WHAT IS SCREW AND BARREL?

A screw and barrel are regarded as the heart of an extruder. Hardness, wear resistance, design, processing technology, and assembly all contribute greatly to its service life, quality, and efficiency. Extruder sets are heavily reliant on their screw and barrel as core components for quality and grade. The screw is made of corrosion-resistant alloy steel with high strength. It is typically made of alloy steel that is heat-resistant, high-strength, strong, wear-resistant and corrosion-resistant. The barrel and screw work together to crush, soften, melt, plasticize, vent, and compact the plastic. Furthermore, the barrel provides mounting support for other devices (heaters, cooling devices, filling hoppers, meters, etc.).
