"PROCEM" is a conductive multilayer metal film designed to impart electromagnetic shielding functionality to polymers and composite materials. As a PVD (Physical Vapor Deposition) coating, "PROCEM" not only offers the advantage of providing electromagnetic shielding but also simultaneously addresses issues such as dimensional and weight changes of the housing before and after coating, as well as the finish quality of masked areas. "PROCEM" meets the needs of the increasingly electronic automotive industry. 【Features】 ○ Contributes to weight reduction ○ Directly coats a complete metal thin film onto resin housings ○ Meets electromagnetic shielding specifications for automotive electrical equipment ○ Higher performance than conventional electromagnetic shielding paints ○ Mass production track record at European factories For more details, please contact us or download the catalog.

HEF, which is well-versed in the sliding theory of mechanical components as a tribology research institute, provides comprehensive engineering services for DLC/PVD technology, including not only the customization of coating processes but also the selection of component materials and heat treatment, as well as pre- and post-coating treatments. 【Key Factors for Maximizing Performance】 ○ Selection of component materials ○ Finishing of coated surfaces ○ Condition of the coating surface For more details, please contact us or download the catalog.

"Micro-texturing" is a technology that reduces friction by thickening the oil film present between sliding components and their counterparts through dimples (holes like those on a golf ball), thereby decreasing partial contact between sliding surfaces. Micro-texturing is a new and practical improvement in the field of surface engineering. 【Features】 - A groundbreaking technology utilizing lubricating piezo-adhesive properties - Thousands of holes per cm² - Capable of transitioning from boundary lubrication to fluid lubrication at lower sliding speed stages For more details, please contact us or download the catalog.

"CERTESS CARBON" is a coating primarily composed of amorphous carbon. It exhibits high hardness along with excellent abrasive wear resistance and anti-adhesive wear properties. Additionally, it demonstrates an extremely low friction coefficient, contributing to the reduction of CO2 emissions from vehicles through the performance enhancement of automotive parts. This product can be coated at low temperatures, eliminating the need for processes to correct deformations (distortions) that occur at high temperatures, thus leading to a reduction in labor hours. Moreover, it does not become soft, making it suitable for the molding of plastics and rubber, molds, as well as automotive and machine parts. 【Features】 ■ High hardness ■ Excellent abrasive wear resistance ■ Excellent anti-adhesive wear properties ■ Extremely low friction coefficient *For more details, please refer to the catalog. Feel free to contact us with any inquiries.

"CERTESS NITRO" is a super-hard thin film coating for mechanical parts formed by physical vapor deposition. Thanks to its unique technology, the coating surface is extremely smooth, eliminating the need for any polishing process after film formation. Additionally, the coefficient of friction is significantly reduced, and resistance to corrosive wear, abrasive wear, and adhesive wear is greatly improved. It is utilized in a wide range of fields, including the aerospace industry, automotive parts, and medical device components. 【Features】 ■ Formed by PVD (Physical Vapor Deposition) ■ No polishing process required after film formation ■ Significant reduction in coefficient of friction ■ Improved resistance to corrosive wear, abrasive wear, and adhesive wear *For more details, please refer to the catalog.
