Be attention please, the hole in workpiece means a pin insert or core in the mold, the pin will be subject to pressure which may cause pin breakage and wear. If the depth is no more than 2 times diame

A hole in the workpiece, there is a core pin'in the mold correspondingly. Core pin Is commonly referred to as core pin shift. A general rule, holes design is that a wall located near a hole should be

There are holes or opening in plastic workpieces which used for a variety of purpose, such as assembly with other parts, decorate the workpiece or give it more eye appeal, or as ventilators and so om.

One of the most common errors is sharp corners in plastics workpiece design. Designing with sharp comers may failure in final use because the sharp corners are areas of high stress concentration and d

The location of ribs and gussets can affect the mold design and the flow length of plastic material in injection process, Gate location can work in concert with the position of ribs and gussets to i

Ribs are longitudinal protrusions on a plastic workpiece that way be used for a number of purposes. The first purpose is to add strength to a workpiece or to add aesthetic features to a workpiece. Th

​The nominal wall thickness effects not only on the strength of workpiece, but also on the haracteristics such as performance, surface aesthetics, appearance, moldability, and economics, so that

Draft angle(Fig. 2. 1)is critical in workpiece design since this directly affects how easily ar object can be ejected from a mold but without be damaged. A slight angle is recommended for all thermopl

The definition of injection molding is as a method of producing objects which is done by the use of an injection molding machine with a heat-meltable plastics material. The shape of products is contro
