[Case Study on Problem Solving] Prevention of Unusual Noises Caused by Stick-Slip Phenomenon Between Resin and Metal

Abolishing grease application and adopting DC2910! Examples of dry lubrication coating dry surfaces.

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.

[Problem-Solving Case] We want to ensure wear resistance and protection of components at high temperatures.

Preventing wear resistance and powder shedding of carbon! A case study on considering coating for carbon.

We would like to introduce a case that solved the issue of wanting to ensure wear resistance and protection of components in a high-temperature environment of 500°C or higher. Initially, we were using a non-coated solution, but there was a possibility of carbon detachment, which could lead to contamination of the surrounding area. Therefore, we applied the heat-resistant and wear-resistant coating CE300-MT. The coating passed the heat resistance test at 600°C, and by covering the surface, we were able to prevent powder shedding. 【Key Points of Problem Solving】 - The environments used by our customers vary from below room temperature to above 1000°C. - Since the characteristics of friction and wear are greatly influenced by temperature, selecting the appropriate coating technology is extremely important. - Our Surface Series offers a lineup that can be used with various materials and environments, including metals, plastics, ceramics, and rubber. *For more details, please refer to the PDF document or feel free to contact us.

[Problem-Solving Case] Wear Resistance Measures for Aluminum Cylinders

Coating only the inner diameter is necessary! A case where masking was performed for appearance reasons.

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.

[Problem-Solving Case] Preventing Noise Caused by Friction Between Metal and Rubber Parts

Very effective as a permanent measure! Examples of dry lubrication coating dry surfaces.

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.

[Case Study on Problem Solving] Wear Resistance Between Molds in Resin Extrusion Molding

Achieving lubrication at high temperatures! Examples of wear-resistant coatings contributing to many fields.

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.

[Case Study] Improvement of Wear Resistance in the Mechanism of Heat Recovery System

Dramatically improve the performance of the underlying PVD coating! Case study in exhaust heat recovery systems for HV vehicles.

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.

[Problem Solving Case] Extension of Mold Lifespan and Maintenance of High Dimensional Accuracy

Change to PVD coating with no dimensional changes! Ensures durability greater than CVD coating!

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.*
