When developing products or trial production of new products, some users often only focus on product research and development at the initial stage, neglecting communication with plastic mold manufacturers.After the product design plan is initially

Because plastic has light weight, good toughness, and easy molding. Because of its advantages such as low cost, in modern industry and daily products, more and more plastics are used instead of glass, especially in optical instruments and packaging

Will the injection mold be put into production immediately after completing? The answer is of course no, because there is still a very important part-trial test. The trial mold is an indispensable part, and the result of the trial mold will directly

The injection molds need to has high corrosion resistance, and many resins and additives have a corrosive effect on the cavity surface. This corrosion causes the metal on the surface of the cavity to dissolve and peel off, resulting in poor appearance

Automobile parts molds require much higher processing equipment than traditional injection molding. Generally, there are two methods for processing.The first is to use a mirror spark machine for processing. In order to ensure the high precision of the

Due to the volume change caused by crystallization in the plastic injection molding process, the pressure during injection molding is high, the melt viscosity difference is small, the interlayer shear stress is small, and the elastic rebound after demolding is...

The gap between the injection molds is too large to cause larger curling and tearing of the edges, resulting in slightly protruding contours and thinning of the edges. Too small a gap between the injection molds will cause the strip to curl slightly and

For high-precision plastic parts, when it is difficult to grasp the shrinkage rate, the following methods are usually used to design the mold: 1. Use a smaller shrinkage rate for the outer diameter of the plastic parts, and a larger shrinkage rate for
