How To Increase The Solidity Of Plaster Line Molds

First of all, to ensure the solidity of the gypsum line mold, we must pay more attention to the selection of raw materials. The raw material should use high-purity gypsum powder, if the gypsum powder is mixed with impurities, it will affect the strength and hardness of the finished product.
Secondly, during the production process, the gypsum slurry is screened. After the gypsum slurry is stirred, it is first screened and then injection molded, so that the processed gypsum line mold is smoother, and the strength and firmness are better.
Gypsum wire mold should be dried after production, in the case of relatively large water content, the hardness of gypsum wire mold is not very good, easy to deform.
