I have already introduced the relevant contents of the double-layer glass for everyone. I believe that everyone has a certain understanding of it. Today, we want to bring you the high-pressure grouting molding of this product. Let's take a look at the interested friends.
The tradition of double-layer glass injection molding is to inject mud into the plaster model, and the mud mold absorbs the moisture of the mud to form a certain thickness of the embryo body. However, in this natural state, the filter-type grouting process is slow, the production efficiency is low, and the formed double-layer glass body structure is inconsistent, the water content is high, and it is not easy to demould, and the double-layer glass is dried and shrunk. The firing shrinkage is large, and it is easy to cause deformation defects.
In order to further absorb the moisture in the mud, to ensure the compactness of the embryo body, to prevent the occurrence of defects such as cracking and delamination of the embryo body, high-pressure grouting is used in the production of the double-layer glass.
