Plastic mold steel is divided into pre-hardened ordinary plastic mold steel, pre-hardened high-quality plastic mold steel, pre-hardened high-hardness plastic mold steel, pre-hard anti-corrosion mirror

In previous news, talked about the deisgn of slider and lifter design, today I would like to talk about the deisgn standard of runner in plastic injection mold. Surface runner and gate design standard

Weld lines, also called knit lines, are formed when two melt fronts converge and join forming a thin fine line in the part. This can be seen in untextured parts and in highly polished surfaces. The

When plastic material is injected into a mold cavity, it is cooled and solidifies to from a part that is made to final part dimensions.However, if the cooling of this part in the mold is not uniform,

Voids are formed inside the wall of a part and can adversely affect the structural performance of the part. Except in transparent parts, voids can be invisible to the naked eye.

Splay marks, also referred to as silver streaks, appear as a blister that radiates over the surface of a part from the gate. If you were to take a small, sharp metal blade and scrape one of these

Sink marks on a plastic part appear as a depression or dip on the part surface. These are created when the shrinkage of the molten core of a part wall is greater that that of the skin. This larger shr

​A short shots or insuficient workpiece fill is a molded part that is underfilled or not filled completely. Visually, this can be seen as sections, such as the last areas of the part to fill, or

Jetting is a phenomenon that occurs in injection molding when molten plastic material flows through the gate and forms a wormlike formation without laying down a skinned surface. The formation beco
