Many injection mold processing is very sensitive to black spots, very annoying, very tangled, very impossible. However, it is said that special attention and happiness should be paid to fuel injection and other products. I hope to cover the black spots and avoid the worry of looking back.
In the past, I always thought that black spots could be covered by spraying rubber oil, but in fact, they couldn't be covered. For example, there is a small black spot on the white product. Once the rubber oil is sprayed, the small black spot is still obvious, because the rubber oil itself has a bright paint. Some injection mold processing has no fuel injection department, and there is no place to test spray, which leads to misunderstanding.
Injection mold processing
If the product background color produced by some injection molds is red, the color sprayed with rubber oil is also red, but there is a better hand feel on the product surface, so we can see what black spots, mixed colors, top white, scratches, dirty things and so on on on the product surface. In the past, self righteous led to the invalidation of more than 1000 products.
