What are the technical applications of two-color mold injection?
Edit:Dongguan Yuexin Plastic Mould Product Co., Ltd.   UpDate:2018-08-25

The mobile phone two-color mold plastic products factory technology is suitable for all kinds of tools and products used in daily life, from the machine base to the machine tool casing, to the tire head screw casing, buttons and various household appliances, all with the mold. The application range of plastic products is also expanding, such as household appliances, instrumentation, construction equipment, automotive industry, daily hardware, etc., the proportion of plastic products is rapidly increasing. The technical application of the mold plastic products factory is as follows:

1. General definition of molds: In industrial production, various presses and special tools installed on presses are made of metal or non-metal materials to produce parts or products of the desired shape by pressure. This special tool is collectively referred to as a mold.


Two kinds of plastics are injected into the mold cavity, cooled and formed in the cavity, and then the upper and lower molds are separated, the product is pushed out of the mold through the ejection system, and finally the mold is closed for the next injection molding, and the entire injection mold enters. The G process is performed in a loop.


three. (1) Design the mold line with a mold, and release the mold together when the mold is opened. The design is the simplest, easy to process, and low cost.


(2) Sluice nozzle: The runner and gate are not on the parting line, usually directly on the product. Therefore, it is necessary to design more than one nozzle parting line. The design is complicated and the processing is difficult.


(3) Hot runner mold: This mold has roughly the same structure and fine nozzle. The biggest difference is the temperature of one or more heat flows, while the heat pump port, without cold feed stripping, sprue and gate directly in the product Up, so the port is not NE. ED demoulding, also known as no-flow system, this system can save raw materials, is suitable for raw materials is expensive, high product requirements, design and processing difficulties, mobile phone two-color mold costs are higher.
