SEAVAC List of Products and Services

We would like to introduce our company's PVD (Physical Vapor Deposition) processing. Since PVD processing is conducted at temperatures below 500°C, it has minimal impact on the base material, allowing for the recycling of molds through film removal and re-coating. Our company employs AIP (Arc Ion Plating) in both continuous and batch types, and uses the UBMS (Unbalanced Magnetron Sputtering) method for DLC. 【Methods】 ■ TiAlN Coating ■ TiCN Coating ■ CrN Coating ■ TiN Coating *For more details, please refer to the PDF document or feel free to contact us.

Titanium-based coatings are widely used as a standard for cutting tools such as drills and cutters, as well as for decorative items. They are also suitable for molds with strict dimensional tolerances.

• others

It is the standard for chrome-based coatings, excelling in anti-adhesion, corrosion resistance, and lubricity. The component elements are stable, and it is sometimes used as a base layer for other coatings for corrosion prevention.

This is a coating that improves hardness by adding carbon (C) to TiN. Since the thickness is equivalent to that of TiN, it can be easily adopted as an upgraded version of TiN.

• others

This is a coating that improves wear resistance and heat resistance by adding aluminum to TiN. In environments exceeding 700°C, the aluminum component combines with oxygen due to frictional heat, resulting in the formation of a strong Al2O3 layer on the surface, contributing to further lifespan enhancement.

In the automotive industry, the use of molds under harsh conditions, such as high-strength steel plates (high-tensile materials) and thick plates, has been advancing, and suppressing localized elastic deformation that induces coating delamination has become a challenge. SEAVAC's original PVD coating, ZERO-I, not only addresses this challenge but also achieves a high hardness of Hv3,500, surpassing TiCN and TiAlN.

Our company is engaged in the technological development of vacuum heat treatment equipment that meets user needs, and by introducing it into the processing department, we provide higher quality services. Our vacuum heat treatment features cooling fans installed above and below the cooling chamber, allowing for cooling with minimal distortion through alternating operation. Additionally, it enables gas retention heating to ensure uniform temperature rise during high-temperature heating and to prevent metal welding. 【Features】 ■ Excellent cooling performance ■ Reduction of distortion through upper and lower cooling fans ■ Gas retention heating (patented technology) ■ Good temperature distribution accuracy ■ Excellent thermal insulation effect *For more details, please download the PDF or feel free to contact us.

【Composite Processing Technology】 While CVD involves "bonding" through chemical reactions, PVD is characterized by "deposition" through collision energy, which generally results in poorer adhesion. To improve the adhesion of PVD, it is effective to reduce the difference in hardness between the substrate surface and the coating film. Particularly, as the hardness of PVD increases, this difference has been expanding. Therefore, our company has adopted the following technologies for substrate reinforcement. 【Overview】 ■ Improved surface roughness and increased surface hardness for high adhesion, and enhancement of internal residual compressive stress ■ WPC + PVD: Paid option ■ Nitriding + PVD: Paid option ■ Lapping before and after coating treatment: Paid option only before coating.

The "S-PVD Coating (TiN for Molds)" focuses on the metallic stability of TiN and is a coating uniquely developed by our company, achieving both high hardness and thick film formation to ensure the long lifespan and high surface pressure of molds. Additionally, through our expertise, we have achieved a hardness improvement to Hv2,600, exceeding the Hv2,300 of TiN. While leveraging the excellent stability characteristics of TiN, it also contributes to enhanced impact resistance and wear resistance. 【Overview】 ■ Color: Gold ■ Film Hardness: Hv2,600 ■ Heat Resistance Temperature: 550℃ ■ Coefficient of Friction: 0.45 ■ Treatment Temperature: Below 500℃ ■ Film Thickness Guideline: 4–6μm *For more details, please download the PDF or feel free to contact us.

Our company offers 'DLC coating' that enables precise and smooth coatings, with excellent sliding properties, release properties, and resistance to adhesion. By adopting the UBMS (Unbalanced Magnetron Sputtering) method and forming a metallic gradient layer between the substrate and DLC, we achieve a highly adhesive film. This standard DLC film has a high reliability with a balanced friction, hardness, and adhesion. 【Overview】 ■ Color: Black ■ Film hardness: 26.4 GPa (Hv2,700) ■ Oxidation resistance temperature: 300℃ ■ Coefficient of friction: 0.2 ■ Processing temperature: Below 200℃ ■ Film thickness guideline: 1 to 1.5 μm *For more details, please download the PDF or feel free to contact us.
