Suitable For Molding Large And Extra Large Parts
- Jan 21, 2017 -

The vast majority of plastic molding processes, in the molding process, plastic and mold are in a very high pressure (pressure), such as the application of a wide range of injection molding, compression molding, extrusion, blow molding, so the application of these molding The production of large-scale plastic parts, not only must be able to withstand the great pressure of the mold, the mold becomes cumbersome and complex, and plastic molding equipment must also be designed and manufactured very solid, machine mold manufacturing difficulty corresponding increase, Increased costs. In contrast, since the rotomoulding process requires only the strength of the frame to support the weight of the material, the mold and the frame itself, and the closing force to prevent material leakage, it is not necessary to mold large and extra large plastic parts The use of very cumbersome equipment and mold, machine mold manufacturing is very convenient, short manufacturing cycle, low cost. Theoretically, there is almost no upper limit on the size of the parts formed by the rotomoulding process. The production of such a large plastic containers, such as the use of blow molding, not very expensive and huge blow molding equipment is impossible.
