How to classify flow injection system mold
Mold can be divided into three types according to different casting system type.
(1)The flowway and gate of the large water outlet mold are on the parting line, and they are removed together with the product at the opening of the mold. The design is the simplest, easy to process and low cost, so more people use the large water outlet system.
(2) fine runner mold runner and gate is not the parting line, generally directly on the product, so to design a set of shuikou parting line, design is relatively complex, processing more difficult. Generally speaking, depending on the product requirements to choose fine nozzle system.
(3) this kind of mould structure and mould of hot flow path is approximately the same fine shuikou, the biggest difference is that the flow is in one or more have temperature and heat flow but heat pumping mouth, no cold feeding demoulding, runner and gate directly on the product, so the port don't need mold release, also known as no runner system, this system can save raw materials, applicable to the raw material is more expensive, high requirement of products, design and processing difficulties, mould cost is higher.
