In injection molding , wall thickness is one of the most crucial design elements. Selecting the appropriate injection molding wall thickness ensures the manufacturer optimizes the part’s appearance and moldability. It also improves the mold’s performance, leading to lower manufacturing costs. Most manufacturers use the prototyping stage to test different wall thicknesses and their impacts on the resulting part. Nevertheless, there are some best practices most manufacturers fo

The injection molding process allows manufacturers to rapidly create parts. The process involves using a mold into which a melted material, called a melt, is poured. The design of that mold is critical to the part’s visual and structural integrity. Mistakes in the design of a mold can lead to an array of defects, including warping, sink marks, and flow lines. This article aims to help manufacturers avoid the poor mold design choices that lead to compromised parts by sharing

Injection molding is a precise process, meaning many things can go wrong. Everything from operator error to minor issues with the mold design can cause problems for the part’s aesthetic or structural integrity. Injection molding flow lines are one such issue. This article explains what they are, how they occur, and the techniques manufacturers can use to avoid them. What Are Injection Molding Flow Lines? Flow lines often appear as a wavy pattern on the surface of a plastic pa

Even minor errors can cause physical defects in a part during the injection molding process. These defects may damage the part’s structural integrity or make it less physically appealing, with both problems likely leading to the part being unsaleable. Injection molding sink marks are an example of such a defect. This article examines what these marks are and how manufacturers can prevent them. What Are Injection Molding Sink Marks? Injection molding sink marks are small depre

Most of the injection molding tools contain air inside the cavity when tightly closed. When plastic is injected the air needs to squeeze and go out somewhere. Mold venting enables air to pack and free up space for the plastic. The Problem With Poor Mold Venting Failure to vent a mold properly increases mold temperatures and increases the melt’s pressure. The combination of these issues can extremely heat the oxygen in the mold, causing an array of visual defects and part int
