Fine nozzle mold: runners and gates 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 complicated, and the processing is more difficult. Generally, the selection depends on the product requirements. Molds can be divided into three types according to the different types of pouring systems. It is suitable for single cavity multi-point feeding or multi-cavity molds. There is no cold material demoulding, runner and pouring.. Our common hot runner system has two forms: single-point hot gate and multi-point hot processing of plastic products gate. The port is directly on the product, so the runner does not need to be demolded. Single-point hot gate uses a single hot sprue sleeve to directly inject molten plastic into the cavity. (3) Hot runner mold: The structure of this type of mold is roughly the same as that of the nozzle. Hot runner system, also known as hot runner system, is mainly composed of hot sprue sleeve, hot runner plate and temperature control electric box. Fine nozzle system.We use many methods when pouring plastic molds. The following Shenzhen plastic mold manufacturers will briefly introduce you! (1)Large nozzle mold: runner and The gate is on the parting line and is demolded together with the product when the mold is opened. This system is also called a nozzleless system, which can save raw materials, and is suitable for situations where raw materials are more expensive and products require higher requirements, design and processing are difficult, and mold costs are higher. The design is the simplest, easy to process, and low cost, so more people use the large nozzle system to work. The biggest difference is that the runner is in one or more hot runner plates and hot nozzles with a constant temperature. It is suitable for plastic molds with a single cavity and single gate; multi-point hot gate branches the molten material to each The sub-heat sprue sleeve then enters the cavity
