(1) Dashuikou mold: The runner and gate are on the parting line, and the product is demolded together when the mold is opened. The design is the simplest, easy to process, and the cost is low. Therefore, many people use the large nozzle system.

(2) Sluice nozzle: The runner and gate are not on the parting line, generally directly on the product, so it is necessary to design a set of nozzle parting lines. The design is more complicated and difficult to process. Generally, it depends on the product requirements. Sluice system.

(3) Hot runner mold: This type of mold structure is basically the same as the fine water nozzle. The biggest difference is that the flow channel is in one or more constant temperature hot runner plates and hot nozzles, no cold material release, flow path and pouring. The mouth is directly on the product, so the flow channel does not need to be demoulded. This system is also called the waterless mouth system, which can save raw materials, 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 molten plastic into the cavity. It is suitable for plastic molds with a single cavity and a single gate. 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.
