How to Maximize Quality in Injection Molding Parts with Minimum Flow Lines
How to Avoid Injection Molding Flow Lines Injection molding is the process of injecting molten plastic material into a mold cavity to form the desired part shape. This process requires careful monitoring and control to ensure a high-quality final product. One of the common problems in injection molding is flow lines, which are visible surface defects caused when the molten plastic flows unevenly within the cavity. To avoid flow lines in injection molded parts, there are several steps that must be taken. 1. Proper Design Considerations The first step in avoiding flow lines is to properly design the part. Considerations…
