The detailed steps of silica gel mold blasting introduce the impact of the surface of the mold on the surface of the mold to improve the surface of the mold and improve the expansion and fatigue resistance of the mold.
In the sand blasting process, different sands are selected for different hardness materials. Common sand materials include glass sand, quartz sand, corundum, iron sand, resin sand, etc., while general silicone rubber products manufacturers use emery and glass in the sandblasting process. Sand two.


Since the inside of the mold does not have high precision for dimensional accuracy, and the general mold is subjected to quenching heat treatment, it is also possible to use two kinds of mixed sand. In the mold process, the coating is mainly taken and some flowers in the mold are cleaned. Traces, and some processes in the mold core are discharged after some process, so it is necessary to choose different sand materials to deal with.


The roughness of the sandblasted surface depends on the coarse grain size of the sand. Therefore, the surface treatment of the molds in the silicone product factory is still very important. The surface requirements of the general products are different. The main function is to use some sandblasting processes in the core which are invisible to the naked eye. Smoothing, removing some residual burrs and rust to make the surface smoother, the mold will not be rough due to the concave and convex grooves during the production process, and the surface of the product will be smoother.


1. Some special products can't be made, such as silicone products.
2. For various reasons, there are still reasons for the occurrence of blisters, etc.
3. Product surface requirements require sandblasting
