Have you ever thought about how artificial intelligence (AI) can change the design landscape in injection moulding? The integration of AI into the design phase opens up new possibilities for efficiency, accuracy and overall product quality. As manufacturers and designers adapt to this technology, understanding the impact of AI on design is key. What is [...]
When doing injection molding DFM, experience matters. Small oversights in draft, wall thickness or tooling assumptions can survive multiple reviews, only to surface once a mold is cut or parts are coming off the press. At that point, the cost is measured not just in dollars, but in schedule delays and product quality. This guide [...]
Injection molding is one of those technologies that is so central to our everyday lives that we hardly notice it. We are surrounded all the time by objects created through this process. Almost everything made from plastic (which is almost everything) is made with injection molding. As a product designer, it’s important to understand this [...]
From specialized cooling component materials and conformal cooling inserts to standard machining practices employing new mold components, mold cooling has evolved and increased in efficiency in recent years. Historically, mold cooling systems were designed to circulate water or other media through the base plates, but not necessarily effectively within the cavities. Newer technology creates optimized [...]
There are dozens of reasons why ejector pins break. Very few of them have anything to do with the pins themselves. here I will discuss how the molding machine and the ejection system can be the culprit. If the molding machine has a bent ejector cross (also known as the machine’s ejector platen, ejector plate, [...]
When you install guide pins and guide bushings within the ejector housing, it is called a guided ejection system. Guided ejection systems greatly increase the longevity of a mold — but they also increase the cost. So, when are they needed and when are they not? In order to answer that question, we need to [...]
An injection-molded part should have a uniform wall thickness for even filling and cooling as much as possible. It is better to modify the geometry of a part to eliminate thick sections rather than design special cooling for the thick sections to prevent or only reduce unsightly sinks, voids and warpage. The poor design will [...]
Injection molding technology continues to evolve, demanding greater efficiency, precision and reliability from moldmakers and processors alike. Recent technical discussions have highlighted practical solutions for addressing persistent challenges in cooling, lubrication, actuation and mold plate control. This article breaks down these themes into actionable insights to help manufacturers achieve better performance and longer tool life. [...]
Venting is one of the most crucial, but often overlooked, aspects of mold design and manufacturing. Parting line vents typically include a primary vent and secondary and tertiary relief channels. The primary vent should be deep enough to evacuate air and gases quickly but not so deep as to create flash. Polishing the vents helps [...]
When a mold is designed with decoupling in mind, the result is lower scrap, faster startups, better part quality and happier customers. For many scientific or decoupled molding has become the gold standard for delivering consistent, high-quality parts, especially as industries demand tighter tolerances, advanced geometries and greater traceability. However, the key to successful decoupled [...]
