PVD Coating Machine

Model No.:

HCCA-1618 Multi-arc Ion PVD Coating Machine   

       The coating machine is used to coat decorative film, especially coat the metal film, namely the term IPS in the clocks and watches industry. It integrated the technology of arc source evaporation coating to make the film. The coating film is corrosion resistance, wearable, good combination between the film and substrate, etc. It is widely used in the ceramics, mosaic, glass ware, watches, jewelry hardware, stainless steel and so on.

Process 

1. Need electroplating for base coating to cover the surface (for brass, zinc alloy etc; Stainless steel parts no need electroplating treatment.)     

2. Ultra-sonic cleaning machine to clean products and keep surface no dust no oil and no wax.    

3. Put into oven for baking    

4. Loading products on PVD fixture, put into PVD machine to get color coating.    

5. QC     

6. Customer can select anti-finger coating according to their requirements   

7. QC and packing   

Main features for PVD coated product 

1. Main material: brass, zinc alloy, stainless steel parts etc. For different materials, the most direct impact on the PVD process is pre-heating temperature, temperature control during the coating process. For example: stainless steel and brass pieces can be pre-heated to 180-degree; zinc alloy parts can be preheated to 140 degree; For different materials, it should make necessary adjustments on the process, in order to get the uniform color, consistent product quality.   

2. Main color: Main color for bath products: imitation gold color, rose gold, gray and black, stainless steel color, bronze etc. HCVAC can get all these colors by one machine. But sometimes, we recommend customers to coat different colors series in different batches. For example: when coat black, we need to fill the vacuum chamber with a lot of C2H2 gas, which will seriously contaminate the vacuum chamber. It will affect the next other colors a lot. In this situation, it’s not the technics problem, but should consider the reasonable production arrangements to ensure the stability of quality.    

3. Quality requirements: color and color difference, corrosion resistance, abrasion wear resistance, adhesion performance etc.. According to our experience, there are allkinds of abnormal occurrence during production. Need to be considered in all aspects of production, such as: In the event of poor bonding strength, we not only have to consider the PVD equipment problem, but also consider: the product itself, coating layer quality problems, cleaning problems, clamping problems, etc.
