For moldmakers who wish they could simulate the molding process without having to build a prototype mold first, Sigmasoft software, designed for 3D injection molding process simulation, may be the ...

Plastic injection moulding process involves several stages. Initially, the polymer material and additives are fed into the heating system of the injection moulding machine. Subsequently, the heated ...

In the modern manufacturing landscape, the quest for consistent and reproducible mechanical properties in injection molded parts is more critical than ever. Achieving this level of quality depends ...

Analytical simulation and modeling of unit manufacturing processes based on knowledge of the underlying process physics and validated by experimental results is becoming a powerful tool to advance the ...

Injection molding is a critical manufacturing process, and has been so for a long time. It still has room to improve in several areas however, and “smart” injection molding equipment is gaining ...

This paper presents a novel method to eliminate halo gloss transition surface defects commonly found on large-scale injection-molded parts. Due to the increasing importance of product appearance and ...

ProMed, a contract manufacturer specializing in liquid silicone rubber (LSR) and highly regulated combination products, has announced new process refinements in the LSR injection molding process ...

Lightweight parts, energy-saving processing or combining several process steps into one. It can all be summarized under one buzzword: sustainability. A technology that is highly promising is ...

Figure 1. Pressurized nitrogen gas is injected into a melt to penetrate the part via a network of thicker cross-sectioned gas channels (click to enlarge). Gas-assist injection molding was developed ...
