1. Rubber compounding
Including mixing of raw rubber, color matching, weight calculation of raw materials, etc.
Second, vulcanization molding
Using high-pressure vulcanization equipment to undergo high-temperature vulcanization to make silicone raw materials into a solid form
3. Trimming
The silicone sleeve products that come out of the mold will be accompanied by some useless burrs and hole shavings, which need to be removed; in the industry, this process is completely done by hand, and some factories are also completed with punching machines.
Fourth, polishing
Since the production environment is not vacuum, the silicone mobile phone cover is inevitably contaminated with dust and impurities, or some products are soiled by the boot personnel, and some cannot be cleaned. At this time, the mobile phone cover can only be modified by sanding. As long as the customer accepts, the sanding treatment is fine Can reduce processing costs and reduce waste.
V. Cleaning
Most silicone products must be cleaned. Dirty is a relatively backward processing process, because the previous process may stain the silicone mobile phone cover. Dust and impurities can be blown off with an air gun, and then cleaned with a dust-free cloth and Tianna water to give customers a satisfactory product.
Six, spray oil
Most silicone cell phone cases need to be sprayed with oil. After completing this process, the quality of silicone cell phone cases will be improved by one level. Most ink manufacturers can provide environmentally friendly touch oil. A good phone case looks at the design and looks at the texture. Some of them are sprayed in spray booths, and some are soaked in ink pools, with various methods.
Seven, baking
After spraying the touch oil, the cell phone case must be dried. After baking in a high temperature oven for about 15 seconds, it can be moved to the side to cool and pack.
