The importance of mold sandblasting to silicone products!baby pacifier bibs manufacture

　　In the manufacturing industry, many friends know the sandblasting process, especially for the products in the industry that use steel parts in the machining center. Sandblasting is even more familiar. Of course, sandblasting of mold molds is also common in the silicone product industry. It is a way to improve the product. Maybe some special products cannot be made, such as silicone products sticking to the mold. When various reasons are searched, or there are reasons such as air bubbles, the mold can be improved by sandblasting. , so that the surface of the mold is affected by the fine sand to improve the surface of the mold, improve the expandability of the mold and the fatigue resistance.

　　In the sandblasting process, different sands are selected for materials with different hardness. Common sand materials include glass sand, quartz sand, emery, iron sand, sea sand, etc., while general silicone rubber product manufacturers use emery and glass in the sandblasting process. There are two kinds of sand. Since the inside of the mold does not require high dimensional accuracy, and the mold is generally quenched and heat-treated, two kinds of mixed sand can also be used. Sandblasting is mainly used in the mold process to obtain coating and clean the mold. There are some flower marks inside, and some processes of the core in the mold have been discharged and some have not been discharged, so different sand materials have to be selected for treatment.

　　The roughness of the sandblasted surface depends on the coarse grain of the sand. Therefore, the surface treatment of the molds in the silicone product factory is still more important. Generally, the surface of the products requires different thicknesses of sand. Grinding and removing some residual burrs and rust make the surface smoother. During the production process, the mold will not be rough due to uneven grooves, and the product surface will be smoother.
