Undercut injection molding deals with complex shapes and design that prevents removing the part from the mold without any damage. Undercut features in injection molding generally increase the overall complexity and associated costs of any design. For these reasons, it is better to avoid them wh

Injection molding plays a critical role in producing plastic parts and designs, and it is a fairly easy procedure. However, manufacturers tend to face some manufacturing difficulties when dealing with press-fit connections, especially without the aid of crush ribs.These tiny structures ensure the sm

Flash is one of the most common defects in injection molding. It’s the thin plastic layer on the parting line or any other part where two dissimilar surfaces from the mold meet and form a boundary. Such areas can create a difference in the expansion and other parameters, which can contribute to incr

With several advantages over other manufacturing techniques, plastic injection molding has become one of the most popular techniques employed by manufacturers worldwide. This technique involves using plastic resins, and its versatility is a welcome feature.However, there are many plastic resins in t

The prototype aims to see exactly how your product appears and acts in a real-world scenario. There are different prototyping processes in the manufacturing industry, ranging from CNC machining to 3D printing. The beauty of these processes is their speed and cost-friendliness, as most of them enable

Injection molding is a great manufacturing process for making aesthetical rapid prototyping and plastic production parts. But if no strict control system for the production process, there may be defects in the plastic molded parts, such as sink marks.So, what is a sink mark in injection molding? Why

Designing draft angles for injection molding can be a hassle. As designers and engineers, we like to work with straight, perpendicular models that are easy and intuitive to read, measure and modify.  However, when it comes time to actually manufacture compo
