What Are The Characteristics Of Mold Plastic Injection

- Sep 01, 2020-

On the market, most of the molds that everyone comes into contact with are mold plastic injection , through which plastic materials are injected to form the desired product. In the mold industry, mold plastic injection are commonly used. So what are the characteristics of mold plastic injection?

Mold plastic injection is a processing method used in mass production of parts, mainly used in industrial fields. The mold plastic injection process is to inject the heated melted material into the mold cavity by high pressure, and after cooling and solidification, the molded product is obtained. According to the molding characteristics, it can be divided into thermoset plastic molds and thermoplastic plastic molds.

1. The mold plastic injection can form multiple plastic parts with complex structure, precise size and good internal quality at one time, so it has been widely used in the production of plastic products.

2. Whether the design and manufacture, geometric shape and structural size design are reasonable, directly affect the rheological properties and filling effect of the polymer melt in the mold channel, and ultimately affect the molding quality of the plastic part. There are many uncertain factors in the preliminary design and development. First of all, from the preliminary design, experienced practitioners are required, and most of them need to rely on the knowledge and experience of mold designers.

3. Phenomena such as jet flow, warpage deformation, weld marks and undershot are all closely related to the design of the gating system.

4. Control the mold plastic injection temperature: one is to heat the mold to the working temperature, and the other is to keep the mold temperature constant at the working temperature.
