On the market, most of the molds that everyone comes into contact with our injection molds. Plastic materials are injected through the mold to form the required products for sale. In the mold industry, injection molds are commonly used. So what are the characteristics of injection molds?
Injection mold is a processing method used in the mass production of parts, which is mainly used in industrial fields. The injection mold 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 is divided into two types: thermosetting plastic mold and thermoplastic plastic mold.
Injection molds can form multiple plastic parts with complex structures, precise dimensions and good internal quality at one time, so they have been widely used in the production of plastic products.
The rationality of design and manufacturing, geometric shape and structural size design directly affect the rheological properties and filling effect of the polymer melt in the mold channel, and ultimately affects 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.
Phenomena such as jet flow, warpage deformation, weld marks and undershot are all closely related to the design of the gating system.
To control the mold 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.
