Understanding the Differences Between Injection Molding and Extrusion

Part production requires careful consideration and planning regarding both the material and process selection. Injection molding vs extrusion is a popular debate because both processes can create repeatable plastic parts at a competitive speed. However, they have some differences as well.

Flow Mark in Injection Molding: Causes and Prevention

Injection molding is a popular manufacturing method for plastic parts. This technology is efficient for high-volume production, maintaining repeatability and cost-effectiveness. However, any deviation in tooling, process variables, and raw material quality causes various defects in molded parts. A flow mark in injection molding is one major defect that influences the finish and aesthetic appeal.
