The application of PVD coating on stretching moulds can significantly improve the product surface hardness, abrasion resistance, corrosion resistance, heat resistance and lubrication, and can facilitate the release of moulds, which can greatly enhance the quality and service life of the moulds.
(1) Improvement of wear resistance: PVD coating has high hardness, which can effectively resist wear and tear, thus prolonging the service life of the mould.
(2) Enhance corrosion resistance: PVD coating can improve the corrosion resistance of the mould, especially in some corrosive production environment, can protect the mould from damage.
3）Improve thermal stability: PVD coating has good thermal stability, can keep the performance of the mould stable under high temperature environment.
(4) Improve lubrication: The coating can provide better lubrication performance, reduce friction and lower maintenance costs.
5) Enhance the quality of the mould: through the PVD coating treatment, the surface roughness of the mould can be improved to enhance the precision and quality of the mould.
