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...
Ever struggled to remove a plastic part from its mold, or noticed unsightly scratches on a finished product? The culprit is often an overlooked design detail: the draft angle. This seemingly simple fe...
In product design, especially for rotational molding, the presence of sharp corners is one of the most common—yet often overlooked—factors leading to structural failure. Rotational molding inherentl...
Ribs are reinforcing structures used to enhance the strength and rigidity of injection-molded thermoplastic parts. They play a crucial role in enabling engineering thermoplastics to successfully repla...
When it comes to product structural design, wall thickness is far more than just a number—it’s a critical factor that influences cost, manufacturing efficiency, mechanical performance, and even aest...
In the world of product design, especially when dealing with multi-material injection molding, the design of the shut-off surface—where hard plastic meets soft TPE (thermoplastic elastomer)—is criti...
