How should we choose mold from three types?

2024-01-31

Plastic injection mould, the abbreviation of a combined plastic mold used for compression molding, extrusion, injection, blow molding and low foam molding, injection mould can be divided into three categories according to the different types of pouring systems:

(1) Edge Gate injection moulding: The runners and gates are on the parting line and are demoulded together with the product when opening the mold. It has the simplest design, is easy to process, and has low cost. Therefore, more people use the edge gate system to operate.

(2) Pin-point Gate injection moulding: The runner and gate are not on the parting line, usually directly on the product, so it is necessary to design an additional set of nozzle parting lines. The design is more complex and the processing is difficult. Generally, the selection depends on the product requirements.

(3) Hot Runner injection moulding: 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 spouts with constant temperature. There is no cold material demoulding, runner and pouring. The outlet is directly on the product, so the runner does not need to be demoulded. This system is also called a water outlet system, which can save raw materials. It is suitable for situations where raw materials are expensive, product requirements are high, design and processing are difficult, and mold costs are high.

Therefore, we need to choose the most suitable mold type based on the specific product materials and output. We, Hongke Mould have been professionally designing and manufacturing molds for more than 15 years. If you have any questions about molds, please feel free to consult.
