Flash, Spew and Burrs: Troubleshooting Mold Problems

An injection molding machine ejecting the finished part from the mold.

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.

Design for Manufacturing: Working Early with Vendors

Computer with CAD graphic design on it.

For many businesses, looking for a parts manufacturing vendor happens late into the design process, often after you’re deep into the design phase. This has its advantages, as the scope of the product has already been figured out and having a CAD or physical prototype allows for quicker mold design. However, it’s not usually the right decision when it comes to the end product. Work with your vendor early in the design process, even before prototype development, can result in a product that’s easier and less costly to manufacture, with fewer mold design and injection molding production problems.
