We would like to introduce a case that addresses the request to "improve the release properties of rubber molds." Physical irregularities were formed on the mold surface through shot blasting, but issues arose as sand got stuck, and unstable grain size led to molding defects. In response, we proposed our 'NiP-PTFE,' which allows for roughness adjustment through film thickness. Since it is an electroless treatment and chemically processed, uniformity can be ensured, and it also allows for the elimination of the blasting process. [Key Points for Problem Solving] - For improving the release properties of resin and rubber molding, there are applicable cases for Teflon coatings, hard chrome plating, PVD-TiN, CrN, etc. - While coatings and plating are important, the surface roughness after treatment is also a very important factor. - In addition to this case, we can also form "micro dimples" on the surface. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where a sealer used in the sealing section of packaging machinery was required to ensure non-stick properties while also demanding high wear resistance and durability. Although a non-stick PTFE coating was used, its hardness was only around Hv400, which posed durability issues. Therefore, we adopted our "Ceramic Coating." This increased the hardness to Hv900, enhancing wear resistance. Additionally, the non-stick performance was secured by reducing the contact area through the action of fine boron nitride particles. [Key Points for Problem Solving] - Even if the counterpart is a film, the hard fillers contained in that film can wear down the counterpart metal. - PTFE coating is relatively hard at around Hv400, but wear still progresses. - The boron nitride contained in the ceramic coating is extremely hard. - Reducing the contact area also excels in wear resistance. *For more details, please refer to the PDF document or feel free to contact us.

We received a request stating, "I don't want to change the type of coating, but I want to extend its lifespan," and we would like to introduce a case where we solved this issue. In fine blanking presses with a plate thickness of 10mm or more, molds have been treated with CVD processing due to the high loads applied to them, which provides excellent adhesion. However, because high-temperature treatment near 1000°C is required, maintaining the precision of the molds becomes very difficult, leading to increased labor for dimensional adjustments. In response, we considered switching to PVD coating, which does not change dimensions. By processing a special micro-dimple (FSA-50) as a base for PVD treatment, we can enhance compressive stress, reduce friction, and improve oil retention, ensuring durability that surpasses CVD coatings. **Key Points of Problem Solving** - PVD coating technology has made significant advancements in hardness, adhesion, and heat resistance. - It has reached the realm of Hv3500 or higher and heat resistance of 1200°C. - It is believed that these physical properties are approaching their limits, and there are increasing cases of adoption involving micro-dimple formation and composite treatments with nitriding as base treatments. *For more details, please refer to the PDF document or feel free to contact us.*

We would like to introduce a case that solved the problem of "wear occurring at the sliding parts of stainless steel in high-temperature environments." The sliding parts were made of SUS materials, and applying lubricants was difficult. We considered nitriding treatment and hard coatings such as DLC, but we could not achieve satisfactory results. Therefore, instead of simply applying a PVD-type film, we significantly improved the performance of the underlying PVD coating by combining it with a high-temperature dry lubrication coating that excels in initial bedding and wear resistance. Our special pretreatment ensured the adhesion of the lubrication coating on the PVD. [Key Points of Problem Solving] ■ Sliding friction between stainless steel tends to cause seizure and galling. ■ Our wear-resistant coating quickly forms an ideal sliding surface and can be applied to areas under thermal load in high-temperature environments and high-performance engines. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of problem-solving using Japan MT's "Dry Lubrication Coating Dry Surface." This involved the application of an insulating film on an aluminum cover for automotive motors, requiring an insulating coating with high thermal conductivity (heat absorption). Initially, we planned to use alumina thermal spraying, but it was very costly, and we needed to secure a film thickness of over 100μm, which posed precision issues. Therefore, we applied the insulating coating DC2830 to ensure insulation at around 20μm. Additionally, we applied the 8441MT coating on top, which also improved thermal issues. The processing temperature was below 200°C, with no impact on the aluminum. [Key Points of Problem Solving] ■ Insulation and thermal conductivity generally have opposing properties. ■ In this case, we attempted to meet both performance requirements by combining a coating that dissipates heat with a highly insulating coating. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case that solved the problem of "wear occurring at the sliding parts of stainless steel in high-temperature environments." The mold material is stainless steel, and since the molding temperature is around 300°C, lubricants such as grease cannot be used. Instead, wear resistance was ensured through hard chrome plating, but there was no fundamental solution to the galling of the counterpart material. Therefore, we adopted a high-temperature dry lubrication coating for the sliding parts of the molds. A large amount of molybdenum disulfide was used to form a hard film, achieving lubrication at high temperatures and preventing galling, as well as ensuring wear resistance. [Key Points of Problem Solving] - The wear-resistant coating is formed with solid lubricants such as abundant molybdenum disulfide and a hard engineering plastic. - Although the hardness is only at pencil hardness, it exhibits excellent strength against friction wear under high loads, contributing to many fields, including machine tools. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case that solved the problem of "unusual noises occurring in the movable parts of metal and rubber in automotive components." Initially, we addressed this issue with non-coated or greased solutions, but these were insufficient as a fundamental countermeasure. While some coatings were used, ensuring compliance varied depending on the material. By applying a rubber-specific coating, we were able to secure low friction across a wide range of applications, eliminating the noise. There were no issues with uneven grease application, and we selected coating part numbers that ensured compliance with rubber. [Key Points of Problem Solving] ■ Typically, grease is often used for stabilization, but due to issues with application equipment and methods, quantification can be difficult, leading to uneven application. ■ By adopting rubber-specific coatings, it is possible to modify the rubber surface itself, making it very effective as a permanent solution. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case that solved the problem of "increased load on components and accelerated wear due to the high-speed operation of machines." While hard chrome plating and other measures were applied at key points, fundamental wear countermeasures were not implemented, and there were components where maintaining precision was difficult with plating due to strict accuracy requirements. Additionally, the material was SK steel, which required processing at temperatures below 200°C to ensure strength. Therefore, we applied the wear-resistant coating MD2812. Thanks to the abundant molybdenum disulfide, initial wear is reduced, and the use of durable resin ensures low friction. The processing temperature is also below 200°C, so there is no impact on the components. [Key Points of Problem Solving] ■ Just being hard is not enough to prevent wear; this is the fundamental issue. ■ The action of molybdenum disulfide contained in the wear-resistant coating imparts load-bearing capacity and low friction. ■ Molybdenum disulfide transfers to the counterpart, creating an ideal surface condition on the opposing side. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case that solved the problem of wanting to prevent the seizing of stainless steel in an environment of 800°C. We were using heat-resistant grease, but there was a possibility of smoke generation in high-temperature areas, and it could also cause difficulties in disassembly after many years of use. Therefore, by applying heat-resistant and wear-resistant coatings, we maintained low torque during assembly. Seizing was prevented even after prolonged use in high-temperature environments, resulting in improved reliability. [Key Points of Problem Solving] - Various components in high-temperature environments face various issues due to the high temperatures. - Friction and wear conditions are more severe at high temperatures than at room temperature, and the progression is also rapid. - Heat-resistant and wear-resistant coatings protect components even in such environments, and the action of solid lubricants can prevent seizing and galling over the long term. - This greatly contributes to improved reliability. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case that solved the issue of "the material was changed to aluminum for lightweight purposes, but the wear amount is greater than that of iron." The outer diameter could not be modified visually, so no treatment was possible. Therefore, both the inner and outer diameters remained anodized in color, ensuring wear resistance on the inner diameter. By applying the wear-resistant coating MD1900 only to the inner diameter, we improved low friction and wear resistance. The strength of aluminum was also secured with a treatment below 200°C. 【Key Points of Problem Solving】 - For areas that cannot be functionally treated with standard plating or coating, masking is performed. - In this case, masking was done for treatment due to visual reasons. - We selected the most suitable treatment from numerous surface treatment coatings, satisfying both appearance and functionality. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case that solved the problem of "seizing occurring during the assembly of stainless steel bottles, making assembly impossible." We were using a PTFE-based coating, but due to insufficient surface pressure resistance of PTFE, we could not meet the performance requirements. Under high load and high surface pressure conditions, the initial break-in coating MD1610 proved effective, allowing for smoother assembly accuracy and productivity. [Key Points of Problem Solving] - Representative examples of solid lubricants include molybdenum disulfide, graphite, and PTFE, each having different load and temperature ranges in which they perform effectively. - In this case, PTFE was insufficient in performance under high load conditions, while molybdenum disulfide, with approximately three times the load-bearing capacity, demonstrated effective performance. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case of preventing abnormal noise caused by stick-slip phenomena between resin and metal in movable automotive cup holders and similar products. We were using grease lubrication to maintain low friction, but it was difficult to quantify, leading to occasional abnormal noise. Therefore, we discontinued grease application and adopted a dry lubrication coating, DC2910, which excels in low friction properties for the sliding parts on the metal side. This change not only improved reliability but also maintained rust resistance through processing on the plating. [Key Points for Problem Solving] - The trend of using resin for parts due to weight reduction is very common, not limited to this example. - Abnormal noises, such as so-called "buzzing sounds," occur due to discontinuous friction states. - To prevent this, the range of coatings with excellent low friction stability is expanding. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of problem-solving for special applications by Nippon MT Corporation. We were using non-coated products, but it was necessary to regularly remove adhesive substances, which significantly reduced productivity. Therefore, we processed with CE100C-MT. The adhesion of substances has decreased, resulting in less maintenance and replacement frequency. Additionally, the film thickness is about 2μm, allowing us to maintain sharpness. [Key Points of Problem Solving] - To make it difficult for adhesive substances to stick, Teflon coating is commonly used. - The film thickness of Teflon coating is about 20μm, so while it eliminates sticking for cutting tools, it may reduce sharpness and lead to other issues. - Generally, the processing temperature for Teflon coating is around 400°C, which can sometimes cause a decrease in the hardness of the cutting tool itself. *For more details, please refer to the PDF document or feel free to contact us.
