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
Just like in all manufacturing, plastic injection molding brings with it their own kinds of defects that can mar or damage parts. It’s critical to work with parts manufacturers who both understand and have the quality control and troubleshooting skills needed to avoid them hurting your bottom line. Not all defects are created equal, and it’s important for you as a client to understand what they are and their causes. Today we’re looking at “splay,” a typically cosmetic defect that might point at issues with your resin or manufacturing process.

Like with all manufacturing processes, plastic injection molded parts can come out of the process with issues and defects that require troubleshooting. One of the most common quality issues is the short shots (sometimes referred to simply as “shorts”), in which the final product is missing material due to the mold not filling completely. In this blog, we’re going to look at the most common causes of this problem, and how troubleshooting short shots is a vital part of quality control and lean manufacturing.
