Here are the key points for selecting resin materials that lead to cost reduction: "Choose resin materials that match the required properties." There are various types of resins and engineering plastics, and their properties differ based on the material. If the equipment being used requires chemical resistance, heat resistance, wear resistance, etc., selecting a material that satisfies all these requirements can lead to very high costs. When selecting resin materials, narrowing down the necessary properties is key to achieving cost benefits. Choosing materials that do not meet the required properties will result in unsatisfactory functionality, so it is important to select materials that balance functionality and cost. [Overview] - There are various types of resins and engineering plastics, and their properties differ based on the material. - Choosing a material that satisfies all requirements can lead to very high costs. - Narrowing down the necessary properties when making a selection provides cost benefits. *For more details, please refer to the related links or feel free to contact us.*

Points for Selecting Resin Materials that Lead to Cost Reduction: "Determine the actual temperature requirements for heat-resistant resins." Resins such as PEEK are available as heat-resistant materials, but the material itself is expensive. While considering cost reductions by changing shapes and precision can yield some effects, there are limits. To reduce costs for heat-resistant resins, it is essential to accurately assess the necessary temperature and select a suitable resin. Choosing materials and resins that precisely meet the design and usage requirements helps avoid unnecessary cost increases. [Overview] - PEEK and other materials are available as heat-resistant resins, but they are expensive. - To reduce costs for heat-resistant resins, first determine the actual required temperature. - Selecting appropriate resins is the shortcut. *For more details, please refer to the related links or feel free to contact us.

This is an introduction to the design points for selecting resin materials that lead to cost reduction, as well as for machining soft materials like rubber and sponge. "For resin and rubber materials, specify by specifications such as color and hardness without designating part numbers." When resin and rubber are limited to unique part names or numbers from specific manufacturers, costs can become high, rather than using generic names that are widely available. One method to reduce the price of resin machined parts is to avoid specifying manufacturer part numbers and instead only specify color and functional aspects. By adopting such methods, companies engaged in resin machining can increase their options for sourcing materials from various routes, leading to cost reductions. [Overview] ■ Limiting to unique part names or numbers from manufacturers can increase costs. ■ Specify only color and functional aspects without designating manufacturer part numbers. ■ Increasing options for sourcing materials from various routes leads to cost reductions. *For more details, please refer to the related links or feel free to contact us.

We will introduce the key points for selecting resin materials that lead to cost reduction: "Considering Unilate for cost reduction of PPS machined products." In resin machining, PPS can be machined with high precision and has excellent heat resistance and chemical resistance, making it widely used in industrial products. However, it is relatively expensive in terms of cost, so even if value engineering (VE) is applied to the shape, there are limits. If cost reduction is necessary, consider Unilate as an alternative material. If it is possible to replace PPS with Unilate depending on the usage environment and situation, significant cost reduction effects can be expected. [Overview] ■ PPS is relatively expensive in terms of cost ■ There are limits even if value engineering is applied to the shape ■ Consider Unilate as an alternative material ■ Cost is about 1/5 of PPS ■ Less warping compared to PPS *For more details, please refer to the PDF document or feel free to contact us.

We will introduce the key points for selecting resin materials that lead to cost reduction: "Dimensions have no special significance; jigs, etc., should be used at the thickness of the material as is." In resin processing, in addition to parts that are incorporated into equipment, there are also workpieces such as jigs used for plating that do not require strict dimensional tolerances. When dimensions and precision are not functionally important for jigs used for plating, it is essential to avoid unnecessary processing steps during the design of those jigs. Specifically, if there is no particular significance to the thickness and diameter of the workpiece, it should be left at the dimensions of the raw material, and surface roughness should also not be specified. [Overview] ■ Requiring constraints such as dimensions and precision increases processing effort and costs. ■ If dimensions and precision are not functionally important, avoid unnecessary processing steps. ■ Make use of the dimensions of the raw material as much as possible. *For more details, please refer to the related links or feel free to contact us.

We will introduce the key points for selecting resin materials that lead to cost reduction: "Specify the hardness and color of rubber sheets within the range of general-purpose materials." When designing parts that use rubber sheets in machines or equipment, you might specify, for example, "black silicone rubber with a hardness of 40°." However, black silicone rubber sheets are typically not available, and the common hardnesses are 50° and 70°. Rubber sheets available in the market have set hardness and colors, and while it is possible to produce rubber sheets outside of these specifications, the costs increase significantly. Therefore, it is essential to carefully check the material, hardness, and color and incorporate them into the design. [Overview] - If it is not a general-purpose rubber, custom orders must be made, which incurs additional costs. - It is necessary to carefully check the material, hardness, and color and incorporate them into the design. - If you are particular about hardness and color, consult a company that specializes in rubber. *For more details, please refer to the related links or feel free to contact us.*

Points for Selecting Resin Materials that Lead to Cost Reduction: "Do not specify the manufacturer, or list it alongside the specification." In machining of resins and engineering plastics, specifying the part number can lead to poor availability, size limitations, or increased costs. Therefore, if the manufacturer is not a concern, do not specify the manufacturer name, or list the part number alongside it. This allows companies performing machining to choose the manufacturer, enabling closer alignment with customer requirements regarding cost and delivery time. [Overview] ■ Specifying the part number can lead to poor availability, size limitations, or increased costs. ■ Only include the general name, or list the manufacturer and part number together. ■ Avoid issues related to delivery time and costs. *For more details, please refer to the related links or feel free to contact us.

We will introduce design points for reducing costs in resin machining: "For expensive resin materials, consider assembly in addition to machining." Resin materials known as super engineering plastics, such as PEEK, are high-performance but also high-cost. If a lot of material is cut away to achieve the necessary shape, material costs become high and waste occurs. For high-cost super engineering plastics like PEEK, it is essential to design in a way that avoids unnecessary material usage. In the case of resin machined products, it is important to comprehensively consider whether machining alone or a combination of splitting and assembly better satisfies functional requirements while also reducing costs. [Overview] - Super engineering plastics are high-performance but also high-cost. - It is necessary to design to avoid unnecessary material usage. *For more details, please refer to the related links or feel free to contact us.

Introducing the design point for reducing costs in resin machining: "In pocket machining, incorporate R or chamfers at the corners." When performing pocket machining on materials like resin, adding R or chamfers at the corners allows for machining without the need to change the end mill. If you can perform chamfering with the same end mill used for pocket machining, you can reduce costs by eliminating tool changes. By considering the machining method during shape design, it is possible to balance functionality and cost. [Overview] ■ Machining is possible without changing the end mill by incorporating R or chamfers. ■ Ensure that the corners have R or chamfers instead of being right angles. ■ Cost reduction is achieved as machining can be done without tool changes. ■ There are various methods for chamfering depending on the shape. *For more details, please refer to the related links or feel free to contact us.

We will introduce the design point for achieving cost reduction in resin cutting: "Reducing costs by reviewing surface roughness." In the cutting process of resins and engineering plastics, how surface roughness is set significantly impacts processing time and influences costs. Therefore, in resin cutting, it is possible to reduce costs by specifying surface roughness only in necessary areas. Additionally, when specifying surface roughness, it is important not to specify more than necessary or to consider relaxing the standards. [Overview] ■ How surface roughness is set greatly affects processing time and influences costs. ■ Costs can be reduced by specifying surface roughness only in necessary areas. *For more details, please refer to the related links or feel free to contact us.

We will introduce the design points for achieving high-precision machining of resin, specifically "points to consider when changing material from metal to resin." In mechanical parts made of metals such as aluminum, there may be cases where the material is changed to resin to achieve lightweight equipment or to enhance the wear resistance and sliding properties of the parts. However, the dimensional tolerances of metals like aluminum cannot always be directly applied to resin. Therefore, when switching to resin, it is necessary to review the dimensional tolerances according to the resin being used. By doing so, it becomes possible to carry out resin processing in a cost-effective manner. [Overview] - The dimensional tolerances of metals such as aluminum cannot always be directly applied to resin. - It is necessary to relax or review the dimensional accuracy. - Understanding the characteristics of each material allows for design while keeping costs down. *For more details, please refer to the related links or feel free to contact us.*

Introducing the design point for achieving high-precision machining of resin cutting: "If you aim for a dimensional tolerance of ±0.01 or higher, consider using aluminum instead of resin." Resin cutting processing can be very challenging in terms of dimensional accuracy, depending on the size of the workpiece. For common resin materials like POM or MC nylon, enhancing dimensional accuracy is quite difficult. For example, trying to achieve ±0.01 will increase processing time and costs. If you want to improve dimensional accuracy, one option is to boldly switch the material to aluminum. Aluminum is lightweight and has high rigidity, making it a suitable alternative to resin in some cases. With aluminum, it is quite feasible to achieve a dimensional accuracy of ±0.01. [Overview] - For common resin materials, enhancing dimensional accuracy is very difficult. - Attempting to achieve ±0.01 will increase processing time and costs. - Replacing the material from resin to metals like aluminum is also an option. - Dimensional accuracy of ±0.01 can be adequately addressed with aluminum. *For more details, please refer to the related links or feel free to contact us.*

Introducing the design point for achieving high-precision machining of resin cutting: "If you want high precision while keeping costs down, use Unilate." To achieve high-precision resin cutting, PPS is suitable due to its low elongation rate and relatively easy machinability. It can accommodate dimensional accuracy of ±0.01mm, but the material cost of PPS is higher compared to other resins due to its precision. Therefore, if high precision of ±0.01mm, which PPS can achieve, is not required, choose Unilate instead. While Unilate has slightly lower machining precision compared to PPS, its material cost is lower, leading to cost reduction. [Overview] - PPS has a higher material cost due to its precision compared to other resins. - If high precision is not necessary, choose Unilate. - The lower material cost leads to cost reduction. *For more details, please refer to the related links or feel free to contact us.*

Introducing the design point for achieving high-precision machining of resin cutting: "For deep hole machining with a small diameter, consider applying pocket machining on the backside." When machining small diameter holes in resin, if the depth is too great relative to the hole diameter, it becomes difficult to achieve hole accuracy such as perpendicularity. Maintaining perpendicularity while machining deeper holes becomes very challenging and increases costs. If deep holes are absolutely necessary for the resin workpiece, consider applying pocket machining on the backside. By doing so, if the depth can be limited to a certain multiple of the hole diameter, perpendicularity can be maintained, leading to high-precision machining of resin. [Overview] - If the depth is too great relative to the hole diameter, hole accuracy such as perpendicularity cannot be achieved. - Design changes should be made to shorten the hole depth by applying pocket machining on the backside. - High-precision resin machining can be realized. *For more details, please refer to the related links or feel free to contact us.

We will introduce the design point that achieves high-precision machining of resin cutting: "Achieving high precision by switching from polytetrafluoroethylene to PPS." Polytetrafluoroethylene is a resin material with excellent heat resistance and chemical resistance, but when it comes to precise machining, it is a soft material. Therefore, depending on the shape, it can be very difficult to achieve accuracy. In cases where heat resistance and chemical resistance are required, as well as precise cutting, adding PPS, a type of resin, to the options expands the design possibilities. [Overview] ■ There are cases where achieving precision with polytetrafluoroethylene is very difficult. ■ Adding PPS, a type of resin, to the options expands the design possibilities. ■ Heat resistance is almost unchanged at around 200 degrees. *For more details, please refer to the related links or feel free to contact us.

Industrial products such as electrical and electronic devices and medical equipment use various materials, including iron and resin. However, in the case of resin, many high-performance products have been developed in response to the demands and changes of the times. The objectives include (1) weight reduction, (2) prevention of scratches during contact with other components, (3) prevention of corrosion such as rust during long-term use, and (4) the pursuit of high precision as long as there are no issues with strength or rigidity. However, improving the functionality of resin also leads to increased costs, so it is essential to accurately understand the characteristics of different types of resin and design accordingly. *For detailed content of the column, please refer to the related links.

• Other polymer materials

Introducing the design point for achieving high-precision processing of resin cutting: "Use PPS for high-precision and burr-free resin cutting." Common resins like MC Nylon and POM have an elongation of 30-40%, which limits the usual dimensional accuracy to ±0.02-0.03mm. Therefore, aiming for higher precision significantly increases costs. When high-precision and burr-free parts are required for resin components that need cutting, consider using PPS. In cases where high-precision resin cutting products are needed, adopting low-elongation PPS makes it possible to achieve dimensional accuracy of ±0.01. [Overview] - POM and MC Nylon are unsuitable for high-precision cutting due to their high elongation. - By using low-elongation PPS, it is possible to achieve dimensional accuracy of ±0.01. - Burrs can also be reduced. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case study of precision machining of "special gaskets made of fluororesin" conducted by our company. To allow chemicals to pass through the evenly drilled fine holes, we use fluororesin, which is not affected by various fluids (liquids and gases) such as general chemical agents and solvents. Additionally, since the dimensional stability of fluororesin is low during machining, the usual tolerance is about ±0.1. However, by performing annealing treatment, it is possible to reduce the tolerance to about ±0.05. 【Case Overview】 ■ Name: Special Gasket Made of Fluororesin ■ Material: Fluororesin ■ Dimensions: Outer diameter φ100 × Inner diameter φ75, Hole φ1.5 × 120 pieces ■ Precision: ±0.05 ■ Features: Surface annealing treatment *For more details, please refer to the related links or feel free to contact us.
