Plastic mold production process and injection processing maintenance

Before mold design, the designer agrees that whether plastic products conform to the principle of injection molding should be discussed in detail with the product designer. This includes a discussion of product geometry, dimensional accuracy and appearance requirements, as well as the need to minimize unnecessary trouble in two-color injection molding.

Process parameters affecting injection quality of plastic mold manufacturers

Considering the thickness of raw materials and articles, the temperature of the barrel should normally be set at a level 10-200 CD above the nominal melting temperature of the material. Amorphous materials such as PS and ABS have no specified melting point, so the barrel temperature should refer to the melt flow index (MI) and spiral process line (SPR).

How can abs injection molding parts be produced by plastic mold injection processing factory to increase brightness?

In the production of plastic parts when the main reason is bad mold injection, industrial raw materials and other aspects, if the mold processing is bad, such as scars, wear, rough and other insufficient, it will be reflected in the plastic parts, plastic parts on poor luster.

Temperature requirements for injection PC products

First of all, PC material characteristics of high definition, good fracture toughness, stress resistance, wide range of application temperature, PC process characteristics are: melting viscosity requirements of cutting rate is small, and the requirements of temperature, no significant solution point, melting body viscosity is high, high temperature PC material and hydrolysis reaction, injection PC products will be easy to crack.

What are the reasons for insufficient and uneven hardness of plastic mold processing?

The hardness of die heat treatment is a very important mechanical property index, and the unqualified hardness is a very serious defect. After heat treatment, insufficient or uneven hardness will reduce the wear resistance and fatigue strength of the mold. Plastic mold processing manufacturers say that this will lead to early failure of the mold and seriously reduce the service life of the mold.
