Effective hard coating for resin molding of glass-filled engineering plastics.

A special coating that does not compromise the high thermal conductivity of beryllium copper. Reduces wear on the base material and delamination of the coating! Improves high-cycle performance in resin molding!

NGK Fine Mold offers the 'DG Coat' and the new 'TG Coat', which are hard coatings used for beryllium copper materials. When molding engineering plastics, the material contains glass, which can cause the coating on the mold surface to peel off and the base material to wear more easily. By applying a coating to the surface of beryllium copper mold components, the lifespan is extended, reducing the frequency of maintenance during molding (such as mold cleaning and part replacement), contributing to lower running costs and improved equipment operating rates. 【Features】 ■ High hardness and strong adhesion to suppress wear and peeling in glass resin molding ■ Maintains high thermal conductivity, demonstrating high cycle performance comparable to the base material ■ Peeling and recoating are possible, allowing for repeated use 【Main Specifications】 Thin film, high hardness coating 'DG Coat' standard film thickness: approximately 8μm, hardness: approximately HV2000 'TG Coat' film thickness: approximately 1μm, hardness: approximately HV5000 * The TG Coat, with a film thickness of 1μm, is also applicable to high-precision parts, further improving wear resistance!

basic information

What is beryllium copper material? It is a high-hardness copper alloy material with excellent thermal conductivity and wear resistance. It can be widely used not only as mold material but also as cooling blocks. It is available in specified dimensions such as round, square, and plate. *For more details, please refer to the PDF document or feel free to contact us.*
