The use of metal inserts in plastic injection molding enhances part functionality but introduces design challenges. Poor insert design can lead to defects like cracks, warpage, or failure. This post o...
The purpose of embedding inserts in plastic products is to enhance local strength, hardness, wear resistance, electrical conductivity, magnetic permeability, etc., to increase the dimensional and shap...
Plastic gears are increasingly used in electromechanical devices, consumer products, and transmission systems where high precision and strength are not the primary requirements. Their advantages inclu...
Plastic threads are integral to countless products, from simple bottle caps to complex automotive assemblies. Understanding how to design them effectively is crucial for ensuring both manufacturabilit...
Holes are essential features in plastic parts, serving various purposes such as assembly, communication, decoration, and more. Common types include through holes, blind holes, stepped holes, special-s...
To avoid stress concentration, enhance the strength of plastic parts, improve melt flow, and facilitate demolding, transitional arcs should be applied at all junctions between inner and outer surfaces...
What is a Boss?Simply put, a boss is a raised, cylindrical feature on a plastic part. Its main jobs are:To provide a seating and strengthening location for fasteners like self-tapping screws or insert...
During the injection molding process, plastics undergo volumetric changes. The dimensions of the demolded part are generally smaller than those of the mold cavity. This phenomenon is known as molding ...
Here are several powerful design strategies that go beyond ribs to create inherently more rigid and stable plastic parts.1. The Power of Curved SurfacesFor large, thin-shelled parts, a flat surface is...
The presence of internal stress reduces the mechanical properties of injection molded products or leads to anisotropy, resulting in poorer durability during use. Especially when the usage conditions c...
