How to create a plastic injection mold?

The injection molding method has been known for many years. Injection molding technology is one of the most common methods used in the plastics processing industry. Manufacturers from other industries also eagerly reach for it. Continuous improvement of technology expands the variety of plastics produced, meeting the requirements set by the Client.

How to create a plastic injection mold?

Molding process

Injection molding process starts from injecting plasticized (heated) raw material to high temperature under a certain pressure into the mold cavity, in which, after it solidifies, a specific shape is given. Thus, the injection molding method makes it possible to obtain a freely designed shape. This technology works best in large-scale production.

Plastics processing with the use of injection molding has several important advantages, which include the variety of the shape of the formed object and its size. When creating small parts, it is common to make several parts simultaneously during one molding cycle. This possibility definitely accelerates the production of plastics.

Temperature during forming

The success of the injection molding process depends on several factors. For smoothly execution, it is essential to ensure the correct parameters during each molding cycle. One of them is the temperature of the material, which is to guarantee adequate fluidity. The second factor is the pressure of the injected material. In order for the plastic mass to be pressed into the mold, the pressure in the machine cylinder must be sufficiently increased. Too much pressure may cause the injection mold to set aside and pour out the material, which may damage the mold or cause the resulting shape to be deformed.
