Y coating series

Unique mold cleaning technology leveraging the expertise of a cleaning agent manufacturer

Whether or not the coating adheres well is determined by the cleaning process.
We have developed our own mold cleaning technology by leveraging the expertise of a cleaning agent manufacturer.

Low temperature treatment (500°C) minimizes dimensional changes and distortion of the material

Low-temperature treatment achieves coatings with the same degree of hardness or higher than TD treatment or CVD. Dimensional changes and distortion of materials can be reduced.

*Steel must be tempered at least twice at 520°C or higher.

Unique film removal technology that leverages our development strengths as a chemical manufacturer

Our technological development as a chemical manufacturer has made it possible to dissolve and remove not only PVD, but also CVD and TD coatings using chemicals. Also, by controlling surface roughness after film removal, we have made it possible to recoat used molds.

For CVD and TD treatment (using shot blasting)

The film removal roughens the mold surface and requires extensive wrapping.
(See figure on the right: Surface after removal of film by shot blasting ×500)

For Y-coat (using dissolution and removal)

A simple wrap can be used to maintain a mirror surface after film removal.

Damage analysis capability and quality assurance

Based on our extensive experience in mold analysis, we perform "magnified observation", "residual film thickness measurement", and "cross-sectional analysis" of damaged molds.
We provide reliable quality and after-sales service with our well-trained staff and analyzers.

Type K + Y-coat treatment

This is a composite treatment in which a hardening treatment (Type K) is applied to the metal material and Y-coat is applied on top of it.

The synergistic effect of "material hardening + Y-coat" provides an effect greater than that of conventional ion plating coatings.

• Cross-section of film

  

• Abrasion and galling resistance

  • Y-coat only
  • Type K + Y-Coat

  The hardening of the base metal surface layer makes it difficult for foreign matter and burrs to penetrate. Also, since the deformation of the base metal due to penetration is minimized, the coating film can easily follow and the chipping breakdown of the film is reduced.

• Features

  Greater abrasion and galling resistance, softening resistance, fatigue resistance, etc.
  Dimensional changes are also the same as for Y-coat only.

• Precautions

  Materials such as stainless steel, cemented carbide, etc., for which the hardened layer is difficult to diffuse, may not be sufficiently effective.
