You know what the surface of the mold handle it? Many people may not understand it now specifically about this issue?

Sandblasting is to quartz sand through a certain pressure air gun shooting at the mold surface to form a layer of frosted plastic mold surface. When the plastic mold injection products, the product will be formed on the surface matte effect. Sand and grit blasting are generally divided into two kinds. For sandblasting the surface of plastic parts easily worn. Striae is formed by a chemical etching method syrup. Striae plane was most species, can imitate a variety of surface effects. For the price difference is very large striae processing, high-tech craft sticks. For different sticks, the price is relatively low. But for molds for automotive interior parts and home appliances, mold and other three-dimensional sticks, the price will be more expensive. Fire patterns refers EDM plastic mold lines left after processing. For fire patterns often die after discharge machining, surface pattern effect left the fire to be, leaving fire patterns accepted treatment. Usually do not deliberately working electrode fire patterns, that costs more. For plastic mold surface treatment technology, we use the most is striae. Of course, what kind of actual product requires surface treatment, still have to decide based on the use of plastic parts.
