Will the vertical rubber injection molding machine mold be resistant to acid and alkali and aging?

Feb 07, 2020

In the process of making silicone molds, we recommend that customers do not add any silicone oil. If necessary, the amount of silicone oil added to the rubber injection molding machine should not exceed 5% to 10%. Too much silicone oil will damage the molecular weight of the silica gel, so the mold produced will not be resistant to acid and alkali and aging.

Why do the molds made by the vertical rubber injection molding machine have traces, streaks, and unevenness on the surface?

This phenomenon occurs because the product or model to be copied is not sanded or polished. Because the model or product itself is actually not smooth or perfect, if the product or model to be copied is not polished or polished, even the best silicone mold will be unattractive and not smooth enough. Another situation is that when the mold release agent is applied, the mold is not smooth without being evenly applied.
