Modular Assembly with Extruder Screw Shaft Assembly and Continuous Helical Flights

Helix pitch accuracy and root diameter cylindricity govern conveying performance in an extruder screw shaft assembly; pitch deviation accumulates along the screw length and alters material residence time in each zone, while root diameter out-of-round causes eccentric barrel clearance that generates localised pressure spikes during extrusion. Prisaisi (Shenzhen, Guangdong, mould factory established 2021, Shajing Bao'an District) turns this extruder screw shaft assembly with continuous helical flights at their close to 4,000 m² Shenzhen facility, with helix pitch, root diameter cylindricity, and OD verified against your released dimensions during first article review. IATF 16949 and ISO 9001 certifications cover automotive, drones, and energy storage extruder screw shaft assembly applications. Include helix pitch tolerance, root diameter, OD fit class, and material specification in your RFQ package.
