The System Type Can Be Divided Into Three Types Of Molds

- Oct 31, 2018-

Large Water outlet mold:


The flow channel and the gate are on the parting line, and the product is demolded together when the product is opened. The design is the simplest, easy to process, and the cost is low, so many people use the large nozzle system to work.


Small Water outlet mold:

The runners and gates are not on the parting line, generally directly on the product. Therefore, it is necessary to design a set of nozzle parting lines. The design is more complicated and the processing is more difficult. Generally, the sluice system is selected according to the product requirements.


Hot runner mold:

The mold structure is basically the same as the sluice. The biggest difference is that the flow channel is in one or more constant temperature hot runner plates and hot boring nozzles. There is no cold material demoulding, and the runners and gates are directly on the product. The flow channel does not need to be demoulded. This system is also called a waterless port system, which can save raw materials and is suitable for the case where the raw materials are expensive and the product requirements are high. The design and processing are difficult, and the mold cost is high.


The hot runner system, also known as the hot runner system, is mainly composed of a hot sprue bush, a hot runner plate, and a temperature-controlled electric box. Our common hot runner systems are available in single-point hot gates and multi-point hot gates. The single-point hot gate uses a single hot sprue sleeve to directly inject the molten plastic into the cavity. It is suitable for a single-cavity single-gate plastic mold. The multi-point hot gate branches the molten material to each through a hot runner plate. The hot runner is re-entered into the cavity, which is suitable for single-cavity multi-point feeding or multi-cavity molds.
