The characteristics of PVD coating on metal surface treatment: life-enhancing, hardening, and value-added, and are widely used in the mold industry for its superior performance such as hard height, high wear resistance, strong corrosion resistance, high temperature resistance, and anti-adhesion.
PVD is the abbreviation of English Physical Vapor Deposition (Physical Vapor Deposition). Ionization occurs, and the acceleration of the electric field is used to deposit the evaporated substances and their reaction products on the workpiece. PVD coating is usually called: metal surface treatment, coating, titanium plating, vacuum coating, chrome plating, titanium plating processing, PVD, surface treatment, titanium plate, surface treatment processing, vacuum coating processing, surface treatment, etc.
1. The surface of the precision pressure-balanced mold can have a very low friction coefficient after being coated with a vacuum coating, which reduces the processing force. After the mold is coated with vacuum coating, the surface hardness can be increased by 5 to 10 times, which can greatly reduce the surface wear, especially when it is used for high-precision machining, it can obtain very excellent surface quality. After the cold stamping and drawing dies are coated with a vacuum coating, the friction force can be significantly reduced, and the scratches and wear during processing can be significantly reduced. Therefore, the life can be increased and the cost can be greatly reduced. Vacuum coating processing
advantage:
The friction coefficient is reduced and the processing force is reduced
Improve surface hardness and greatly extend mold life
Prevent the product from pulling and pulling, and improve product quality
Eliminate the trouble of unloading, polishing and reloading the mold, and improve efficiency
2. Due to its complex structure, the plastic mold is difficult to process, so the cost is relatively high, so improving the life of the mold is a major issue, especially the mirror surface and the etched surface are particularly easy to wear, which has always been a very annoying thing. distressing thing. The improvement of the surface hardness of the vacuum-coated plastic mold makes the wear resistance significantly improved; and the enhanced surface finish of the mold and the reduction of the friction coefficient make the rubber compound flow better and the plastic product easier to demould. At the same time, the vacuum coating forms a dense protective layer on the surface of the mold due to its special lattice structure, which can effectively solve the drawbacks of corrosion. More importantly, because our coating will not change the surface condition of the mold, whether it is a mirror surface or an etched surface, even the extremely demanding CD mold. Vacuum coating
advantage:
Higher wear resistance and greatly extended die life
The compound can flow for a longer time and the filling effect is better
The surface quality of plastic products is improved, and the defect rate is reduced
Easier demolding, even avoiding the use of release agents
Effectively prevent corrosive raw materials from eroding the mold base
Molds are easy to clean with longer cleaning cycles
3. Cutting tools such as milling cutters, drills, saw blades, thimbles, taps, reamers, etc., after being coated with vacuum coating, the cutting edge part can withstand high temperatures of up to 800 ℃ during the cutting process and still maintain good hardness. The surface has more wear capacity and lower friction coefficient, so it can reduce the cutting force and improve the surface quality and precision of the product. After being coated with nano-coating, it can not only prolong the service life of the tool, but also improve the cutting parameters, and even realize dry cutting, remove the use of cutting fluid, protect the environment and reduce the manufacturing cost.
advantage:
Significantly improve tool life
More high temperature resistance, dry cutting possible
Improve cutting parameters
Increase productivity
Improve the quality of processed products
4. The vacuum coating in the electronics industry is not only applied to the knife molds in the hardware and plastic machinery industries, but also has many excellent properties such as high surface hardness, good finish, and high precision, making it also popular in the electronics industry. For example, terminal blades, IC packaging molds, micro-milling and micro-drilling for PCB processing, PCB hole punching molds, gold finger molds, etc. The coating on these products not only solves many problems for users, but also brings them more benefit.
advantage:
The coating thickness is very thin, which can meet the high-precision requirements of the electronics industry. It is completely environmentally friendly and meets various safety requirements (such as the RoHS directive) to improve the wear resistance of tools or parts and ensure the stability of product quality.
