Warpage can be one of the more frustrating injection molding defects, as it can range from a simple aesthetic problem to an issue that compromises the entirety of the part’s function. This defect can result from any number of variances occurring within the injection molding process. Fortunately, a combined knowledge of plastic flow behavior, material science, and machine and tool settings can prevent this defect. Let’s discuss how experienced manufacturers avoid warpage in plastic injection molding.[Read more…] about How to Avoid Warpage in Plastic Injection Molding
The goal of every manufacturer is to provide a final product free of defects by implementing quality control measures. However, if you find your manufactured parts are fracturing into separate layers, you’re witnessing a mode of failure known as delamination. The source of delamination can range from the plastics you use to the condition of your injection mold. Fortunately, Midstate Mold & Engineering has the experience necessary to troubleshoot the different causes of delamination in injection molding.[Read more…] about What Causes Delamination in Injection Molding?
Every manufacturing process can introduce different defects into the final product. The goal of every manufacturer is to have the machines, process, and quality assurance in place to reduce and even remove flaws from final parts and products. Welcome to another blog on defects and how to detect and troubleshoot them. This week we look at jetting defects in plastic injection molding. Let’s go over what they are, how they are caused, and what injection molding companies do to avoid them.[Read more…] about Injection Molding Jetting Defects: Signs and Troubleshooting
Every manufacturing process can introduce different defects into the final product. The goal of every manufacturer is to have the machines, process, and quality assurance in place to reduce and even remove flaws from final parts and products. In this blog, we’re looking at one of the more common part defects that can come from injection molding: weld lines. Let’s go over what weld lines defects are, how they are caused, and what injection molding companies do to avoid them.[Read more…] about Weld Line Defects in Plastic Injection Molding
The goal of every plastic injection mold and parts manufacturer is to have each mold and part come out without issue or defect. However, like with all manufacturing processes, these flaws can be introduced due to a myriad of situations. Today, we’re looking at a common issue with plastic injection molding that goes by multiple names: flash, spew, or burrs, in which there is excess material attached to the part. In this blog, we’re going to review the molding defect, its causes, solutions, and how to avoid it in the first place.[Read more…] about Flash, Spew and Burrs: Troubleshooting Mold Problems
When it comes to your plastic products, the only holes that should exist are the ones on the designs. Like with all manufacturing processes, plastic injection molding can introduce defects into their products. The important thing for the manufacturer and client to do is to detect the defects and then troubleshoot the problems that are causing them. This blog focuses on the two major source of holes – voids and bubbles – in plastic injection molding: vacuum voids and gas pockets.[Read more…] about Injection Molding Defects: Vacuum Voids and Gas Pockets
