1. Hot runner mold: The structure of this mold is roughly the same as the thin nozzle. The biggest difference is that the runner is in one or more constant temperature hot runner plates and hot jacks. There is no cold material demoulding, and the runner and the gate are directly On the product, so the runner does not need to be demolded, this system is also called no nozzle. In the system, raw materials can be saved, which is suitable for situations where raw materials are expensive and product requirements are high. Injection mold manufacturers are difficult to design and process, and mold costs are high.
2. Large gate mold: The runner and gate are on the dividing line, and when the product is demolded together in the mold, the design is simple, the processing is easy, and the cost is low, so more people use large gate systems to operate.
3. Thin nozzle mold: runners and gates are not on the parting line, generally directly on the product, so it is necessary to design more than one nozzle parting line. The design is more complicated and the processing is more difficult, which generally depends on the requirements of the product And the choice of fine nozzle system.
