How many types of PVD nano coatings are there?What are the advantages?

PVD coating

Characteristics of metal surface treatment PVD coating: increase life, increase hardness, increase value, and its high hardness, high wear resistance, strong corrosion resistance, high temperature resistance, adhesion resistance and other superior performance is widely used in the mold industry.

PVD is English Physical Vapor Deposition (PVD), is refers to under the condition of vacuum, with low voltage, high current arc discharge technology, the use of gas discharge for vacuum coating equipment so that titanium plate evaporation and evaporate matter and gas ionization, using electric field acceleration, cause the evaporation material and the reaction product Deposition on the workpiece.

PVD coating is usually called: metal surface treatment, coating, titanium plating, vacuum coating, chromium plating, titanium plating processing, PVD, surface treatment, titanium plate, surface treatment, vacuum coating processing, surface treatment, etc.

1. The surface of the precision weighing mold can have very low friction coefficient after being coated with vacuum coating, which can reduce the processing force.After the mold is coated with vacuum coating, the surface hardness can be increased by 5 to 10 times, and the surface abrasion can be greatly reduced.

After the cold blanking and drawing die is coated with vacuum coating, the friction can be significantly reduced, and the scratch and abrasion can be significantly reduced.Therefore, it can increase the life span and reduce the cost significantly.

Advantages:

Reduce the friction coefficient, reduce the machining force

Improve the surface hardness, greatly extend the life of the mold

Prevent product hair, pull, improve product quality

Save the trouble of unloading mold, polishing and reloading mold, improve the efficiency

2, the plastic mold due to its complex structure determines the processing difficulty, so the cost is relatively high, so to improve the life of the mold is a major topic, especially the mirror and etching surface, it is particularly easy to wear, which has been a very painful thing.

The surface hardness of the plastic mold coated with vacuum increased, and the abrasion resistance increased significantly.And because of the enhancement of the surface finish and the reduction of the friction coefficient of the mold, the plastic material flow is better and the plastic product is easier to take off the mold.

At the same time, because of its special lattice structure, the vacuum coating forms a dense protective layer on the surface of the mold, which can effectively solve the problem of corrosion.More importantly, because our coating will not change the surface condition of the mold at all, whether it is mirror or etched surface, even the very high requirements of the CD mold

Advantages:

Wear resistance is higher, mold life is greatly extended

The flow time of rubber material is longer and the filling effect is better

The surface quality of plastic products is improved and the defect rate is reduced

Demoulding is easier, even avoid using demoulding agent

Effectively prevent corrosive material from corroding mold matrix

The mold is easy to clean and the cleaning cycle is longer

3. The vacuum coating of the electronic industry is not only applied in the knife mold of the hardware and plastic machinery industry, but also highly favored in the electronic industry due to its high surface hardness, good finish and high precision.

For example, terminal blade, IC packaging die, PCB processing of micro-milling micro-drilling, PCB hole stamping die, goldfinger die, etc., coating on these products not only solve many problems of users, but also bring them more benefits.

Advantages:

The coating thickness is very thin, which can meet the requirements of high precision in the electronics industry and is completely environmentally friendly. It can meet all kinds of safety requirements (such as RoHS instruction) to improve the wear resistance of tools or parts and ensure the stability of product quality
