In the high-stakes world of injection molding, downtime is the enemy. A mold on the bench is a line not producing. Among the most frequent culprits of unplanned stops are three common types of physical damage: broken pins, wear, and chipping.
Understanding how to properly diagnose and repair these issues is not just a maintenance task—it's a critical skill for maximizing productivity and protecting a valuable asset. Here’s your practical guide.
If you've been around injection molding, you've heard of hot runner molds. They're often described as the "premium" option—significantly more expensive than traditional cold runner molds, yet overwhelmingly preferred for high-volume production. Why is there such a paradox?
Let's demystify hot runner technology by answering two fundamental questions.
If you're involved in plastic part design, procurement, or manufacturing, you've likely heard the terms "two-plate mold" and "three-plate mold." While they both make plastic parts, the choice between them fundamentally impacts cost, part appearance, and production efficiency.The core difference lies

When it comes to branding or adding functional markings to products, manufacturers often face a critical choice between three major processes: Laser Marking, Silk Screen Printing, and Pad Printing. Each technology has its own superpowers and limitations.
Choosing wrong can lead to faded logos, high production costs, or a finish that doesn't match your product's quality. This guide cuts through the complexity, providing a clear comparison to help you make an informed decision for your specific application—especially for injection-molded parts like your gas-assist cabinet handles.
You can see the main difference between two-shot injection molding and overmolding in how they make parts with different materials. Two-shot injection molding uses one machine to put two materials or colors together in one step. Overmolding puts a layer on top of a part. This is often done to make a

Overmolding (also known as two-shot molding or insert molding) is a transformative manufacturing process that bonds two different materials into a single, functional part. From soft-grip tool handles to sealed electronic components, it delivers unmatched benefits in ergonomics, aesthetics, and performance.
However, achieving a perfect overmolded part is notoriously tricky. The process sits at the intersection of material science, precision tooling, and nuanced process control.
Here, we break down the most common overmolding challenges into four critical categories and provide practical solutions to overcome them.
