The Challenge Injection molding flash, or flashing, is excess material that is forced out of a mold cavity at the parting line or ejector pin locations. This surface defect mars the finish of molded parts and can interfere with their performance. Traditionally, injection molders remove flash by hand. However, manual trimming is slow, time-consuming, and […]
The Cryogenic Deflashing Process Cryogenic Deflashing is a process designed to remove molding flash created during the molding process. Molding flash can be found on molded parts along the parting lines, gate vestiges, and where pins and slides are located. In order for molded parts to complete their desired function, the residual molding flash needs […]
Batch Deflashing to Remove Mold Flashing We often hear from molders and OEMs that they have mold flashing after their injection molded plastic and rubber parts are manufactured. There are many ways for mold flashing to form on your parts during the injection molding process. Surfaces where sliding and moving parts meet will wear with […]
Are you sick and tired of paying for quality issues caused by hand deflashing? We hear it all the time. You have a section in your manufacturing operation with a team of deflashing personnel sitting around a table. Your team may have seasoned veterans, but you still end up with a varying degree of flash […]
What’s the difference between cryogenic deflashing vs. cryogenic deburring? They’re both secondary processes that remove surface defects without changing critical part dimensions or surface finish. They both subject parts to very cold temperatures, and it’s this cryogenic treatment that makes part defects brittle and easy-to-remove using a special non-abrasive media. In addition, both cryogenic processes […]
