Injection molding is one of the most versatile and cost-effective manufacturing processes for producing plastic parts at scale. From Legos to iPhone cases, countless products we use every day started as molten plastic injected into precision-machined steel molds. However, injection molding only delivers on its potential if you design parts specifically for the process. Unlike […]

Troubleshooting for injection molding process is a critical skill for anyone working in plastic manufacturing. As an intricate production method with many variables, issues inevitably arise that require quick identification and remediation to avoid costly downtime. In this comprehensive guide, as a professional injection molding manufacturer, we’ll cover proven troubleshooting methodologies to efficiently resolve defects

What is Large Part Injection Molding? Large part injection molding is a type of injection molding process used to produce sizable plastic components. Like all injection molding techniques, it works by injecting molten plastic material into a mold cavity under intense heat and pressure. As the plastic solidifies, it hardens into the shape of the

The debate between 3d printing versus injection molding has been going on for years in manufacturing circles. With advancements in additive manufacturing, the question arises – is 3d printing cheaper than injection molding? This comparison seeks to provide an up-to-date, data-driven analysis on the cost differences between these two popular manufacturing processes. As a professional

Cold slugs are a common issue in injection molding that can lead to defects on plastic parts. In this comprehensive guide, as a professional injection molding manufacturer, we’ll cover what exactly causes cold slugs, as well as solutions for preventing them. What Is Cold Slug in Injection Molding? A cold slug refers to a small

Flash is one of the most frustrating defects in injection molding. This thin layer of plastic along the parting line of your molded parts not only looks bad but can also lead to costly post-processing. So what causes flash in the first place? And more importantly, how can you prevent it from happening? In this

Flow lines are a common defect that can occur during the injection molding process. These visible lines on the surface of a plastic part are mainly an aesthetic issue, but they can still cause problems. So what exactly causes flow lines? In this complete guide, as a professional injection molding manufacturer, I’ll cover the key

Weld lines are one of the most common defects found in injection molded plastic parts. When two flow fronts of the molten plastic converge in the mold, they may not fully fuse back together. The result is a visible line on the part called a weld line, which indicates a weak spot. As a professional

What is a Gate in Injection Molding? An injection molding gate is a small opening that allows molten plastic to enter the mold cavity during the injection molding process. The gate controls the flow and direction of the plastic as it moves from the runner system into the cavity to form the desired part. Proper

Packing pressure is a critical yet often misunderstood parameter in the injection molding process. As a professional plastic injection molding manufacturer, I’m here to demystify packing pressure, why it matters, and how to optimize it for high-quality parts. Stick with me! What is Packing Pressure in Injection Molding? In short, packing pressure is the pressure
