Plastic Mold Classification Based On Pouring System

Plastic Mold Classification Based On Pouring System
  • (1) Large nozzle mold: the runner and gate are on the parting line, and they are demolded together with the product when the mold is opened. The design is the simplest, easy to process, and the cost is low, so many people use the large nozzle system to operate.
  • (2) Fine nozzle mold: runner and gate are not on the parting line, generally directly on the product, so it is necessary to design an additional set of nozzle parting line, the design is more complicated, the processing is more difficult, and it is generally selected according to the product requirements Fine nozzle system.
  • (3) Hot runner mold: The structure of this type of mold is roughly the same as that of the fine nozzle. The biggest difference is that the runner is located in one or more hot runner plates and hot mouths with constant temperature. The outlet is directly on the product, so the runner does not need to be demolded. This system is also called a waterless system, which can save raw materials. It is suitable for the situation where the raw materials are expensive and the product requirements are high.
