Injection molding is a manufacturing technique that demands careful attention to wear tolerances for components like screws and barrels

The extrusion screw barrel has a significant place in plastic and rubber product industries

The screw is the core component of extruders and injection molding machines, responsible for uniformly mixing, plasticizing, and transporting raw materials. Its operational status directly impacts production efficiency and product quality. Therefore, regular cleaning and maintenance of screws are essential to ensure optimal equipment performance. This article provides comprehensive technical guidance on the necessity of cleaning, cleaning methods, precautions, and professional advice for routine maintenance.

The screw and barrel are core components of extruders and injection molding machines, and their dimensional precision is critical to equipment performance. In practical applications, measuring screws and barrels involves not only basic geometric dimensions but also surface quality, fitting clearance, and material property assessments. This article provides a detailed overview of the tools, methods, steps, and key technologies for measuring screws and barrels, offering systematic guidance for production and quality control.
