Sandblasting, leather grain and fire pattern belong to the category of mold surface treatment. These three surface treatment technologies, among which sandblasting and skin grain are used more, there are some fire-retardant patterns, but not too much. For a general description of the three processes of sandblasting, leather and fire patterning of plastic molds.
Sand blasting is to shoot quartz sand through a auto Cap machine certain pressure air gun to the surface of the mold to form a frosted surface on the surface of the plastic mold. When a plastic mold is molded into a product, a matte effect is formed on the surface of the product. Generally, sand blasting is divided into two types: fine sand and coarse sand. For sand blasting, the surface of the plastic part is easily worn away.
The skin texture is made by a chemical water etching method. The leather grain has the widest variety and can be used to imitate various effects. The price difference for the dermatoglyph processing is very large, and the technical content of the dermatoglyphic process is high. For different skin textures, the price is relatively low. However, for three-dimensional leather lines for automotive interior parts molds and home appliance molds, the price is much more expensive.
The fire pattern refers to the texture left after the machining of the EDM plastic mold. For the fire pattern,Auto Plastic Parts Mold after the mold is discharged, the surface of the product can be fire-retarded, and the pattern of the fire is accepted. Generally, the electrode processing pattern is not intentionally made, and the cost is high.
For the plastic mold surface treatment technology, we use the most skin texture. Of course, what kind of surface treatment is required for the actual product, or whether it depends on the use of the plastic part.
