Filling or pouring mold is used for relatively smooth or simple products. No mold line saves time and labor, it is the product or model you want to copy, surrounded by rubber or glass. Put the vacuumed silica gel directly into the product. After the silica gel is dried and formed, the product is taken out and the mold is formed. (Note: The casting mold is generally made of softer silica gel, so it is easier to demould. Will damage the products inside the silicone mold). It is a combination of solid and liquid, using products such as mobile phone sets, luggage sets, etc.
