In recent years, with the continuous increase of mold enterprises and the continuous development of economic globalization, the mold industry has developed rapidly. Some customers are not too familiar with the composition and classification of plastic mold processing. Today, Shenzhen Guan Hualong tells everyone about the knowledge of plastic mold technology.

1. 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. Nozzle system.

2. Dashui Mold: The flow channel 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.

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 demoulding, runners and gates. Directly on the product, so the flow channel does not need to be demoulded. This system is also called the waterless port system, which can save raw materials. It is suitable for the case where the raw materials are expensive and the product requirements are high. The plastic mold manufacturers are difficult to design and process, and the mold cost is higher. 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 spray 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 manifold is re-entered into the cavity, which is suitable for single-cavity multi-point feed or multi-cavity molds.
