Undercut is one of the most common yet confusing concepts in injection molding. As a professional plastic injection molding manufacturer, I often get questions from customers about what undercuts are and how to design parts with them. In this complete guide, I’ll explain everything you need to know about undercuts in injection molding – from […]

Injection molding is one of the most common manufacturing processes for creating plastic parts. However, warpage is a common defect that occurs during injection molding, causing parts to bend, twist, or deform after they’ve been ejected from the mold. So what exactly causes warpage? And what can you do to prevent it? In this complete

Weld lines, also known as knit lines, are a common injection molding defect that can affect the appearance and performance of molded plastic parts. In this complete guide, as a plastic injection molding manufacturer, we’ll cover everything you need to know about weld lines, including what causes them, how to prevent them, and how to

Sink marks are a common injection molding defect that leads to uneven surfaces and poor aesthetics. As a professional plastic injection molding manufacturer, I’ve worked with manufacturers who’ve struggled with sinks. By optimizing materials selection, process parameters, tooling design, and part geometry, you can avoid sinks altogether. What Causes Sink Marks in Injection Molding? Before

Injection molding is one of the most common manufacturing processes used today. From car parts and electronics cases to toys and medical devices, injection molded plastic parts are everywhere. But what exactly is injection molding and how does it work? In this comprehensive guide, as a professional plastic injection molding manufacturer, I’ll walk you through

Injection molding is a common manufacturing process used to produce plastic parts. It involves injecting molten plastic material into a mold cavity and allowing it to cool and solidify into the desired shape. One key component of the injection molding process is the die or mold. This is the custom-machined metal tool that forms the

Reducing cooling time is crucial for injection molding operations. The cooling stage often takes up the majority of the overall cycle time. So optimizing cooling can lead to big productivity gains. In this complete guide, I will teach you several techniques for slashing your cooling times as a professional plastic injection molding manufacturer. By the

Reducing flow marks requires adjustments to process parameters and often some trial and error. However, with persistence and attention to detail, their occurrence can be decreased significantly or even eliminated. As a professional plastic injection molding manufacturer, I will cover the root causes of flow marks and proven methods for reducing them in this guide.

Splay defects can seriously undermine the quality of injection molded parts. These streaks and discolorations on the surface not only hurt aesthetics but also compromise strength. So how do you get rid of splay in injection molding?

In this comprehensive guide, as a professional plastic injection molding manufacturer, we’ll dig into the root causes of excessive part weight and actionable strategies to optimize for lightweighting in injection molding. Whether you’re a mold designer, process engineer, or work on the manufacturing floor, you’ll discover tons of tips to slash grams and take costs out of plastic parts.
