Apply hard overlay coating on the surfaces of various hard tools such as taps, milling cutters, and hobs. Increase tool life Equipment specifications: customized according to user requirements, more suitable for user needs.
 

PVD (Physical Vapor Deposition) coating is a technology that deposits a thin layer of material on the mold surface, aiming to improve the mold's hardness, corrosion resistance, surface quality, service life and product quality.
The selection and application of PVD coating depends on the specific purpose of the mold and the quality requirements of the products produced. In the automotive manufacturing industry, the most important component of automotive molds is the cover mold, which is used to manufacture all parts on the car.

The advantages of PVD-plated drawing dies mainly include improving hardness, corrosion resistance, improving surface roughness, reducing material adhesion, extending service life, improving product quality, and giving special functions.
PVD technology has more advantages than traditional electroplating technology, such as using a vacuum environment to reduce oxidation reactions, improving coating quality and durability, and providing a higher deposition rate and more uniform coating thickness to meet the needs of mold surfaces of different thicknesses and shapes.

The PVD coating of the tool obtained by using PVD technology, GIS plasma etching technology and MS magnetron sputtering technology not only has good resistance to oxidation decomposition, high temperature wear resistance and diffusion performance, but also reaches the international advanced coating process level in actual measurement.
 

PVD coating technology has the advantages of low temperature and environmental protection. It is suitable for coating treatment of carbide precision and complex cutting tools, and has little effect on the bending strength of the tool material, especially below 600°C. PVD coating has a wide range of applications, including but not limited to drill bits, turning inserts, welding tools, reamers, oil hole drills, carbide end mills, taps and indexable milling inserts.

PVD AlCrN plating technology has the following characteristics:

. Low friction coefficient: This means that during use, the AlCrN coating can reduce friction, reduce wear, and thus increase the service life of tools or components.
. Wear resistance: The AlCrN coating has excellent wear resistance and can maintain stable performance during long-term use, reducing performance degradation caused by wear.
. Low film stress: This helps to reduce cracking or shedding of the coating due to excessive stress during use, and maintain the integrity of the coating.

The core component of the super-hard coating equipment has small particles, slow deposition, very good surface finish of 2-3 microns on one side, and adjustable magnetic field. can coat TiN,TiCN.ALTiN,ALCRN,CRN,TaC etc.
