Double-Shot Molding Process

In recent years, with the development and universality of the plastic industry, the application scope of plastic products has become more and more extensive, such as: household appliances, instruments and apparatus, construction equipment, automobile industry, daily hardware and many other fields. However, with the increasing trend of plasticization of industrial products and daily products, the requirements for the strength and precision of plastic products are also increasing. Therefore, in order to make the mold have better strength and precision, it is necessary to adopt double-shot molding process. The following is a brief introduction to this process.

The mold is a tool for producing plastic parts. It is generally composed of several groups of parts, and there is a mold cavity in this combination. During injection molding, at first, the double-shot mold is clamped on the injection molding machine. Secondly, the molten plastic is injected into the molding cavity, and plastic parts are molded by cooling in the cavity. Thirdly, the upper and lower molds are separated, and the products are demoulded from the mold cavity by the ejection system. At last, the mold is closed again for the next injection molding. It is the entire and cyclic injection molding process.

In the injection molding production process, it needs to use something, such as plastic raw materials, color powder, gate materials, molds, injection molding machines, peripheral equipment, fixtures, sprays, various auxiliary materials and packaging materials. To keep smooth production operation of injection molding dept, it is necessary to manage the personnel, materials, equipment and tools involved in each link and positions. It mainly includes the operation and coordination management of raw material room, crushing room, mixing room, production site, post-processing area, tool room, semi-finished product area, office and other areas.

Due to the mold or semi-finished product needs to be rotated, the requirements for mold design and machine parameters are more precise. In addition, due to the high variability of double-shot molding, in order to achieve smooth production and meet the expected ideals, all mold designs must be considered simultaneously with product design.

In summary, with the continuous maturity of double-shot molding process, our country is gradually becoming a manufacturing base of global consumer product . In recent years, plastic product manufacturers in South China have taken on many orders that require double-shot molding process, which has enabled our country to further improve double-shot molding process.
