Pretreatment process of vacuum coating equipment tool coating

Vacuum coating equipment and tool coating pretreatment process. Now, all patented vacuum coating machine vacuum coating technologies are playing their specialties in the field of tool coating, making the tool coating process develop rapidly. However, in the actual production process, the success or failure of the film quality is often the choice of a suitable pretreatment process. According to personal experience, the customers faced by tool coating companies include various industries, such as: electronics industry, injection molding industry, metal molding and so on. The production department accepts a wide variety of products. Especially for new industry customers, new test samples, how to choose a suitable pre-treatment process, is the most important issue before the eyes of process developers.

The following uses a test sample as an example to briefly describe the pre-treatment process selection:

1. Fully communicate with customers to understand the basic performance of the sample and the workplace. This is not only beneficial for the formulation of the pre-treatment process, but also the basis for the selection of the later film layer.

2. Analyze the performance, surface condition and important surface of the sample.

3. Select the necessary pre-treatment links, which may include grinding, polishing and other processes. Of course, this is not a necessary link. However, a reasonable increase of the above processes can double the service life of the film.

4. According to the surface shape, pollutant type, surface state and other factors, select pre-cleaning, cleaning and other links. In this process, most companies currently choose chemical removal methods, which brings the disadvantage of chemical corrosion. Especially for an unfamiliar sample, experienced production personnel will pay more attention to avoid damaging the customer's product. A better option is to remove the contaminants physically.

5. For samples with special shapes or structures, effective means must be selected, methods removed, and gadgets must be made when necessary. Otherwise, even if the test is successfully completed in one sample, mass production requirements cannot be guaranteed.

6. Test the effect of pretreatment. This is particularly important for sample testing. The inspection should focus on whether the sample is damaged or corroded due to the pre-treatment process, and whether there are new defects in the pre-treatment link.

7. The sample test should be done by the senior engineer himself, and the process flow will be compiled after the process is obtained and then put into production.
