Injection molding, blow molding, and extrusion are three of the most widely used plastic manufacturing processes, each designed for specific product types, production volumes, and performance requirements. Understanding the differences between these technologies is essential for B2B manufacturers seeking efficiency, quality, and long-term cost control. This guide compares injection molding machines, blow molding, and extrusion based on clamping force, shot size, mold size, production volume, ene
