The "IMP Block" has been widely used as a cutting material that originated from the control of voids, which is a benefit of our IMP construction method. By leveraging the advantages of injection molding, we can offer short delivery times, small lots, and low prices. In addition to the existing six sizes, we have newly added "φ60×5mm to 100mm" to our lineup. With a rich variety of sizes, we can meet diverse needs. **Advantages of the new sizes:** - Stable production of small parts - Reduced total costs by minimizing cutting removal amounts - Lower stress during cooling due to the small size, which is advantageous for preventing deformation *It is ideal to obtain one product from one block of this material. If multiple products are taken, there are concerns about deformation due to stress.* We have launched a specialized homepage for the well-received "IMP Block." It contains various information that we have accumulated over time. For more details, please see the link below.

• Mold Design

Compared to machined products, PLAMO's injection compression molding can achieve approximately one-third (as a guideline) reduction in manufacturing costs. In situations where machining is applicable: 1. High precision (geometric tolerances, dimensional tolerances, etc.) ⇒ PLAMO technology applicable 2. Thick-walled shapes (which cannot be molded in the first place) ⇒ PLAMO technology applicable 3. Small production lots (frequent prototyping or shape changes, etc.) ⇒ not applicable Example) Calculated at 3,000 units/year* Machined product: part cost ¥600/unit, annual expenses ¥1.8 million PLAMO molded product: part cost ¥200/unit, mold production cost ¥1 million, annual expenses ¥1.6 million It can be less than machining costs within a year. If production continues over multiple years, it leads to significant cost reductions. *Subject to change based on product shape, materials, and other conditions; this is merely a guideline. If you provide product drawings, machining costs, and annual production plans, we will offer a free simulation of manufacturing costs. Additionally, we are open to consultations regarding requests such as avoiding asset capitalization of molds. ★PLAMO provides financial support for parts development for a limited number of cases each year. Please contact us for more details. Experience the areas that can only be achieved with PLAMO technology.

I believe you have experienced a significant decrease in strength that falls far below the strength data listed in the material catalog for plastic injection molding. It is often the case that the strength of plastic molded products cannot be achieved as indicated in the catalog. This decrease in values is particularly pronounced in reinforced resins with fibrous additives, and it becomes a major issue due to the nature of the reinforced resin. For example, when a decrease in strength occurs, the typical countermeasure is to increase the thickness, but it is important to understand that this adjustment may lead to significant problems. In cases where high strength requirements are necessary, it is essential to be involved from the product design stage, identifying areas of strength reduction and considering appropriate countermeasures. The aging degradation of the resin must also be taken into account. Our company has the expertise to carry out these processes. We would be grateful if companies considering lightweighting or resin substitution for metal parts, or those struggling with insufficient strength and contemplating abandoning development, could contact us. (The photo shows the results of analyzing the glass fiber orientation distribution using simulation software for injection molding. The strength of resin parts depends on fiber orientation.)

• Mold Design

The development of plastic injection molded products is often met with various troubles. While the content varies, are you not giving up because you can't address them in advance? There are many performance requirements for plastic parts, and designers specify product shapes and dimensions that meet these requirements. However, many issues arise during the actual molding and prototyping stages. After that, we go through mold modifications and other processes to refine the product until it meets the requirements. The effort involved in mold modifications and prototyping can be quite wasteful. Some products may not meet satisfaction at all, leading to cases where development is abandoned, which is very unfortunate. Our company supports stable product creation by adjusting the shapes of resin products. We assist those who are not familiar with designing resin parts or who feel uncertain about their designs.

PLAMO has decided to establish a mold manufacturing division starting in April 2021. The operation of this division will be managed by a mold manufacturing company with whom we have had a long-standing relationship, joining us as part of PLAMO. Their extensive experience will allow for meticulous care. In the flow from mold order to product manufacturing, which is common in the plastic injection molding industry, we strongly propose product shapes. Naturally, we focus on satisfying performance requirements and ensuring stable production, achieving the following: - Simplification of mold structure - Extension of mold lifespan - Reduction of dimensional accuracy variation between shots - Minimization of warping and deformation We promise to support engineers who are inexperienced in resin design by constructing optimized mold structures, eliminating unnecessary mold structures, and reducing mold manufacturing and product production costs. *For more details, please refer to the PDF document or feel free to contact us.

Until now, the production of plastic parts required experience and intuition. Our company utilizes simulation software to minimize post-molding troubles by making predictions in advance. Our strengths lie not just in performing simulations, but in: 1. Tuning product design (identifying problem areas and countermeasures based on results generated by simulations) 2. Optimizing molds (release properties, structural simplification, mold cooling, cavity arrangement, gas venting, etc.) 3. Improving moldability (broad optimal molding conditions, increased processing speed) 4. Handling difficult-to-process materials, such as PPSU and PEEK. Through these efforts, we achieve comprehensive quality stability and reduced manufacturing costs. Additionally, our unique technology, injection compression molding (IMP/IMM method), allows us to meet high-quality demands. The IMP/IMM method can accommodate materials and shapes typical of general injection molding while achieving: 1. Reduced sink marks and warping 2. Exceptional dimensional accuracy 3. Reduced voids 4. Improved weld line strength These effects are unparalleled compared to conventional molding, enabling stable production in repeated cycles. If you are looking for a new manufacturing partner, we invite you to experience our high level of technical expertise. Please feel free to contact us.

There are several ways to reduce mold manufacturing costs, but the reality is that many manufacturers leave it entirely to mold production companies. If product manufacturers are leaving it entirely to others, that’s one thing, but when molding companies that receive production requests from manufacturers completely delegate the task to mold makers, it not only negatively impacts productivity and quality but also fails to contribute to the accumulation of technology, which is problematic. The key point is the quality of the mold production company you choose to work with. It is important to consider not only dimensional accuracy but also whether the mold design takes into account moldability and whether the mold considers the characteristics of the intended resin, as a comprehensive sense of balance is essential. The recommended approach is to design with consideration for everything from product design to molds and molding. [To reduce initial costs] ■ Have mold production done overseas, especially in China ■ Obtain comparative quotes from domestic companies and request the cheapest one ■ Make unreasonable requests to the companies you frequently work with *For more details, please refer to the PDF document or feel free to contact us.

Increasing the strength of resin parts is a research theme for our company. The strength requirements for plastic materials often depend on the material and product shape, and high-dimensional processing has not been achieved in molding. Countermeasures in product design include "adding reinforcement ribs," while material-related measures involve "selecting materials that meet strength requirements," and molding measures include "producing products that do not have shrinkage or voids." 【Countermeasures in Product Design】 ■ Add reinforcement ribs ■ Use larger radii at corners ■ Insert metal to increase local strength ■ Maintain appropriate thickness ■ Avoid weld lines in areas that may lack strength *For more details, please refer to the PDF document or feel free to contact us.

Silver streaks, referred to as "silver," are defects that occur on the surface of resin products, resulting in silver lines. The causes include "gases generated from within the resin" during the plasticization process, "air trapped in the resin," and "air trapped in the mold during the injection process." In response, measures such as setting a lower resin temperature or using a cylinder with gas vents are employed to suppress gas generation.

There are two types of warping: one that occurs immediately after demolding and another that gradually occurs after demolding. The causes include "imbalance in cooling balance," "uneven internal stress," and "flow direction of the resin during injection." As countermeasures based on molding conditions, methods such as considering areas with poor heat dissipation and designing molds with cooling balance in mind can be employed. [Causes of Warping] ■ Imbalance in cooling balance ■ Uneven internal stress ■ Flow direction of the resin during injection *For more details, please refer to the PDF document or feel free to contact us.

Resin undergoes volumetric shrinkage during the cooling and solidification process. The high volumetric shrinkage rate, particularly in thicker sections, is a primary factor. The layer that solidifies early after injection on the product surface, referred to as the skin layer in the industry, can lead to voids inside the product under conditions where pressure loss occurs during the cooling process. If the surface solidification layer is thick and robust, voids may form inside the product. Conversely, if the surface solidification layer is thin and soft, sink marks may occur. Additionally, sink marks and voids can occur simultaneously. Measures to mitigate sink marks involve adjustments in molding conditions and product design. 【Methods to Address Molding Conditions】 ■ Increase the internal pressure of the resin ■ Thicken the surface solidification layer to forcibly create voids ■ Use foamed materials to mold without lowering internal pressure *For more details, please refer to the PDF document or feel free to contact us.

A void refers to bubbles that occur inside a product. Since they are internal, the presence of voids is not noticeable in the appearance of anything other than transparent resin. As a result, they are a type of defect that can easily be overlooked, but they become an unstable factor in terms of strength. In particular, the reduction in strength due to voids is particularly evident under compressive forces. The causes of voids occurring when "air is already present in the injected material" include air that mixes in while the resin is being plasticized, as well as gases and water vapor generated during the plasticization process. These can be improved by adjusting the molding conditions. [Causes and Countermeasures (Partial)] <Problem> ■ When air is already present in the injected material <Countermeasures> ■ Air that mixes in while the resin is being plasticized and gases generated during plasticization 　→ Improved by adjusting molding conditions such as water vapor ■ Air trapped when injecting into spools, runners, and cavities 　→ Adjusting molding conditions has limited effectiveness; modifying the mold is effective *For more details, please refer to the PDF document or feel free to contact us.

A weld line is a phenomenon that occurs when resin splits into two streams and then rejoins in products that have multiple gates or contain windows or holes, due to the fact that the surface of the combined resin is slightly solidified. The basic method to visually eliminate it is to create conditions under which the surface of the joining resin is less likely to solidify. Methods such as "raising the mold temperature to delay solidification under molding conditions" cannot completely eliminate it, but can reduce the visibility of weld lines to a certain extent. To completely eliminate it, it is necessary to heat the mold to a temperature close to that of the resin. This method is called "heat & cool." Since the product will not release while the mold is heated, production is carried out by rapidly cooling the mold. [Methods to reduce the visibility of weld lines] ■ Raising the mold temperature to delay solidification under molding conditions ■ Setting a fast injection speed to thin the surface solidification layer ■ Setting a higher resin temperature ■ Setting a higher resin pressure *For more details, please refer to the PDF document or feel free to contact us.

I will explain how the dimensions of the mold affect the product. The shrinkage rate of crystalline resins is about 1% to 2%, while for amorphous resins, it is about 0.2% to 0.5%. Just by looking at this, you can understand that amorphous resins have an advantage in terms of dimensional stability. A lower shrinkage relative to the mold dimensions means that the product can be produced in a shape closer to that of the mold. In contrast, crystalline resins have a larger shrinkage rate, making them more prone to variations in product dimensions. Currently, even for products made from the same material, the shrinkage rates specified by different molding companies to mold manufacturers vary. One point to be cautious about is that the shrinkage rate calculation method provided by material manufacturers is based on very general molding assumptions. In cases of thick walls or complex shapes, these assumptions may not hold, so each molding manufacturer accumulates their own know-how or makes adjustments to mold dimensions and molding conditions, and we respond accordingly. *For more details, please refer to the PDF document or feel free to contact us.*

The cause of burr formation is due to gaps in the mold that allow resin to flow in. The reasons for gaps in the mold include "issues with the alignment of the mold, resulting in gaps" and "problems with mold strength, causing gaps to open under resin pressure." As a method of improvement, there are techniques that consider the mold, such as the "IMP method/IMM method," to suppress the occurrence of burrs. 【Molding Conditions】 ■ There are inherent issues with the alignment of the mold, resulting in gaps. ■ There are problems with mold strength, causing gaps to open under resin pressure. ■ Due to molding conditions, excessive injection pressure and injection speed can result in the clamping pressure being insufficient, leading to parting opening or mold plates bending. *For more details, please refer to the PDF document or feel free to contact us.

The issue of voids, especially vacuum voids, in plastic parts has been a long-standing challenge due to their difficult control. We face the problem of voids in various situations, such as with POM materials used in mechanical components and in thick-walled molded products. However, the solutions are limited, and measures such as reducing the product thickness negatively impact strength. The "IMP method," uniquely developed by PLAMO, is a technology that completely controls voids even in very thick products. It is an application of the technology proven with "IMP blocks" and demonstrates effectiveness for various shapes.

The "IMM method" was completed in 2011 as a technology to solve the strength deficiency of weld lines in fiber-reinforced resin materials. This technology is considered a part of injection compression technology, characterized by its ability to indirectly apply compression and internal flow in areas where compression is needed. The very high compression force generates a strong holding pressure effect, allowing for intentional changes in the internal flow of the resin during injection. The compression effect suppresses shrinkage and produces high dimensional accuracy. The internal flow promotion effect improves the strength of the weld lines in fiber-reinforced resins and allows for control of fiber orientation. In particular, the IMM method can achieve high precision control through its uniquely developed machinery, independent of the injection process, resulting in no variation between shots and stable effects. It is possible to accommodate this method by modifying existing molds. 【Features】 ■ Measures for dimensional accuracy, shrinkage, and deformation of thick and uneven products ■ Improvement of weld line strength and control of fiber orientation ■ Flexibility in product shapes that can be accommodated, such as slide block structures

"Voids" in resin products can lead to stress concentration and become the starting point for failure. They are particularly vulnerable to compressive forces. We achieve stable void-free production with the 'IMP method,' providing highly reliable components. 【What is the IMP Method?】 The IMP method (In-Mold Pressing) is our original processing technology and a type of molding compression method. Molding compression involves injecting resin into a mold and compressing the injected resin during and after filling to shape it. *The IMM method is also effective against voids. However, due to the origins of its technology, the IMP method operates at a higher level and can accommodate thick-walled shapes, while the IMM method is effective for products that are not as thick. Our method offers flexibility in the shapes of products it can accommodate and has the advantage of being able to adapt to mold structures such as slide cores. 【We solve the following issues】 - We want to minimize voids at a high level. - The molding cycle has become longer. - It is difficult to manage variations between shots.

A weld line is the location where molten resin meets within the mold during injection molding, resulting in a Y-shaped groove at the junction. Particularly in the case of fiber-reinforced resins, the fibers at the junction are oriented differently than in other areas, leading to a significant reduction in strength. The "IMM method" is a type of compression molding technology that allows molten resin to flow into the cavity through a compression action. Similar to the IMP method, it offers flexibility in product shape. By intentionally altering the internal flow of molten resin during injection to disperse the weld lines, we can change the fiber orientation and improve the strength at the weld line area. While the V-shaped groove may become shallower, it cannot be completely eliminated. Therefore, please consider this as a different technique from the "Heat & Cool technology" aimed at improving appearance. It is possible to address this through modifications to existing molds. 【We can solve the following issues】 - I want to increase the strength of the weld line to a higher level. - I am selecting unnecessary materials to increase weld line strength. - I am increasing the wall thickness to address the weld line strength.

• Other machine elements

The independently developed IMM method controls fiber orientation at a high level, creating high-strength components. In injection-molded products made from fiber-reinforced resin, it is often the case that the strength does not match the catalog strength. A significant reason for this is that the fiber orientation differs greatly from the catalog strength. The "IMM method" is a type of compression molding technology that allows molten resin to flow into the cavity through compression. Similar to the IMP method, it offers flexibility in product shapes. In conventional injection molding technology, the fiber orientation is determined by the act of injecting molten resin into the mold. The position of the gate is a very important condition from a strength perspective. The IMM method intentionally generates internal flow of the molten resin during injection, which allows for some control over fiber orientation, differing from conventional injection molding. Please consider this method for cases requiring very high strength. It is possible to accommodate by modifying existing molds. 【We will solve the following issues】 - There is a partial lack of strength, and we want to enhance it. - There is a directional lack of strength, and we want to improve it.

High precision is an eternal theme in plastic molded products. High-precision parts enhance the overall performance of the product. In injection molding, the stability of the holding pressure effect directly impacts dimensional accuracy, but the timing of the gate seal required for holding pressure varies between shots. The IMM method has extremely low variability between shots, and its repeatable dimensional stability is significantly higher compared to conventional molding. This effect can be further enhanced by advanced mold correction, achieving even higher dimensional accuracy. The "IMM method" is a type of compression molding technology that allows molten resin to flow into the cavity through compression. By compressing the molten resin during injection and allowing it to flow into the cavity, a significantly higher holding pressure effect can be expected compared to the variability in gate seal and low holding pressure effect typical of standard injection molding. It is possible to address this by modifying existing molds. 【We can solve the following issues】 - I want to achieve high precision in dimensions. - The molding cycle has become longer. - There are products that do not fit within dimensions due to variability between shots.

"Sink marks" not only result in visual defects in resin products but also reduce dimensional accuracy and are a major cause of deformation. The "IMM method" is one of the compression molding technologies that allows molten resin to flow into the cavity through the act of compression. Similar to the IMP method, it offers flexibility in product shapes. Conventional injection molding technology achieves holding pressure effects through the injection unit, but pressure loss occurs due to runners and gates. Additionally, controlling the timing of gate sealing is not easily managed, making high-level control difficult. The IMM method intentionally generates internal flow of molten resin during injection, allowing for high holding pressure effects through compression force, which can suppress sink marks. If you are considering very high sink mark control, please give it a try. It is possible to accommodate this by modifying existing molds. 【We will solve such problems】 - I want to suppress sink marks at a high level. - The molding cycle has become longer. - Sink marks occur in thick-walled products or at the filling end, and I cannot suppress them.

The elimination of warpage and deformation in plastic molded products is an eternal theme. One of the advantages of plastic molding technology is the freedom of shapes that can be molded, but this can lead to warpage and deformation. Particularly, once a mold has been created, the countermeasures are limited, resulting in defects that trouble manufacturers. **Main Causes of Warpage** - Uneven mold temperature: Molds are operated at temperatures lower than the melting resin temperature to cool and solidify the molten resin. At this mold temperature, partial temperature differences occur due to the product shape and component structure. This disrupts the cooling balance of the parts, resulting in deformation during demolding. - Flow direction during injection: In injection molding, the shrinkage rate may differ between the flow direction and the perpendicular direction. This is particularly evident in fiber-reinforced resins. The unevenness of this shrinkage leads to warpage and deformation. - Uneven filling pressure: When injecting the molten resin into the mold, the filling pressure can be uneven. For example, the pressure is high near the gate, while it is lower on the opposite side of the gate. Additionally, areas with thin product thickness experience higher pressure, while thicker areas have lower pressure.

We have solved many difficult problems in the field of plastic injection molding. The focus of our work includes: - High dimensional accuracy - Strength - Voids - Weld lines - Shrinkage, warping, and deformation We specialize in the manufacturing of mechanical parts. These technologies are the result of knowledge gained through collaborative development with our customers and have become treasures for our technological advancement through partnerships with related companies. Our company has developed thanks to the Japanese spirit that supports manufacturing. Although our contribution may be small, our goal and support is to give back. Even in the case of a single IMP block, we have overcome challenges with the support and wisdom of many people to develop new materials into block form. *【Image Description】* This is a diagram showing the fundamental differences between our uniquely developed processing technology and conventional molding. It presents the results of measuring the pressure waveform during the injection and holding pressure stages by installing pressure sensors in the mold. This diagram well illustrates the advantages and characteristics of the "IMP method" and the "IMM method." The "IMP method" allows for prolonged holding pressure, while the "IMM method" can apply very high injection pressure compared to conventional molding.
