How to classify plastic mold factory products

According to the type of gate system, plastic molds can be divided into three types

1. Hot runner mold: The structure of this mold is roughly the same as that of the nozzle. The biggest difference is that the runner is located in one or more constant temperature hot runner plates and hot nozzles. There is no cold material demoulding, runner and casting. The port is directly on the product, so there is no need to demold the runner. This system is also called a nozzleless system, which can save raw materials and is suitable for situations where the raw materials are expensive and the product requirements are higher. The design and processing are difficult, and the mold cost is high.

2. Large nozzle mold: runners and gates are on the parting line, and they are released together with the product when the mold is opened. The design is very simple, easy to process and low cost, so more people use large nozzle systems for work.

3. Fine nozzle mold: runners and gates are not on the parting line, usually directly on the product, so it is necessary to design a set of nozzle parting lines, the design is more complicated and the processing is more difficult. Generally, the diluent should be selected according to product requirements. Nozzle system etc.
