Tools Hard Film PVD Vacuum Coating Equipment is an optimized device designed to improve the performance of tools (especially cutting tools, molds, etc.).
Its core goal is to deposit one or more layers of thin films (such as TiN, TiAlN, CrN, AlCrN, DLC, etc.) with extremely high hardness, wear resistance, low friction coefficient and good chemical stability on the tool surface, thereby significantly extending the tool life, improving processing efficiency and improving the surface quality of the workpiece.
Features：
High hardness and wear resistance
The hardness of the deposited hard coating is very high, much higher than that of the tool base material (such as high-speed steel, cemented carbide).
It greatly improves the tool's ability to resist wear (abrasive wear, adhesive wear), and extends its service life by several times or even more than ten times.
Excellent film-base bonding
Ensures a strong metallurgical bond or mechanical bite between the coating and the tool substrate to prevent the coating from peeling off under heavy load, impact or high temperature.
Good thermal stability and oxidation resistance
Common coatings (such as TiAlN and AlCrN with high Al content) can still maintain high hardness and oxidation resistance at high temperatures (up to 800-900°C), and are particularly suitable for high-heat applications such as high-speed dry cutting.
Low friction coefficient
The coating surface is smooth and has a low friction coefficient (such as DLC coating), which reduces cutting force, reduces friction heat, inhibits the formation of built-up edge, improves chip removal, and improves processing accuracy and surface finish.
Low temperature deposition process
The temperature of PVD process is relatively low.
It can prevent the tool substrate (especially high-speed steel) from softening, deforming or generating internal stress due to high temperature tempering, and maintain the original strength and toughness of the substrate. This is one of the core advantages of PVD in the field of tool plating.
Film uniformity and complex shape coverage
By optimizing the cathode (target) layout, workpiece holder design (revolving planetary holder) and process parameters, we ensure that a coating with uniform thickness and consistent performance is obtained on the surface of complex-shaped tools (such as milling cutters with cutting edges, drills, gear hobs, and deep-cavity molds);
Applications:
Cutting tools
Molding mold
Wear-resistant parts
The PVD coating machine for tool coating is a key equipment for improving the performance of core tools in modern manufacturing.
Its low-temperature deposition, high hardness, excellent bonding strength, good thermal stability, complex shape coverage and environmental protection characteristics make it widely used in cutting tools, forming molds (stamping, die casting, injection molding, etc.) and various wear-resistant parts.
By depositing high-performance hard coatings, it can significantly extend the life of tools, improve processing efficiency, improve product quality, and reduce comprehensive production costs. It is an indispensable part of modern efficient, precise and green manufacturing.
