When designing molded threads for plastic parts, the goal is to achieve reliable function without compromising part strength or manufacturability. Unlike metal threads, plastic threads require special...
Plastic bearings are load‑bearing moving components in which relative motion occurs between the plastic part and other mating parts. Proper structural and dimensional design is critical for performan...
When selecting wall thickness for a plastic part, its moldability must be considered. The flow length — defined as the distance from the gate to the last filling area — must stay within the allowab...
Bosses play a critical role in many plastic part designs, serving as connection and assembly points for screws, inserts, or other components. Proper boss design ensures mechanical strength while avoid...
In injection mold design, the cavity and core are the primary components that shape the plastic part. The cavity forms the outer surface of the part, while the core forms the inner surface, as shown i...
Ribs are essential features in plastic part design. When designed correctly, they improve part performance without increasing wall thickness. Below are the main functions of ribs and key design guidel...
In injection mold design, guide pins and guide bushings ensure proper alignment between the moving and fixed halves of the mold. Poorly designed guiding components can lead to mold damage, inconsisten...
Why Are Fillets (rounded corners) Important?Most plastic parts have multiple intersecting surfaces. Unless otherwise specified, these intersections are typically designed with fillets rather than shar...
Why This Matters: Poor gas channel design leads to incomplete filling, gas blow‑through, and part defects. This guide shows you exactly where to place gas inlets and how to design gas channels for re...
In conventional manufacturing, many plastic parts require post‑molding assembly with other components — such as metal base plates or other plastic parts. This not only demands a lot of manual labor ...
