Problems solved by technology

[0002] Since PDCPD products only need an injection pressure of 4-10 MP, theoretically speaking, the strength of the resin mold should be able to meet the mold life of about 3000; but in the actual application process, the life of the mold is less than 10 sets. Problems; After analysis and research by our company, we found that the current PDCPD rapid molds are mainly filled with ordinary resin molds, but there are the following problems:
[0003] 1. The product is difficult to demould;
[0004] 2. Ordinary resin molds cannot withstand high temperatures above 200 degrees; resulting in easy damage to the surface of the mold;
[0005] 3. The heat dissipation performance is too low; the current PDCPD resin mold life cannot meet the design goal; the damaged part is mainly caused by excessive heat concentration due to poor heat dissipation of the mold;
[0006] 4. Since the local temperature exceeds 400 degrees, the polymerization reaction of PDCPD cannot proceed normally, resulting in a decrease in the strength of the product; a certain odor will be produced; these odors are the concatemers produced by the incomplete polymerization reaction, which itself will Reduce the strength of the product and other performance indicators
