Reciprocating Screw Element
Product Name: Reciprocating Screw Element
Model：φ11 mm ~φ350mm
Applicable Brands：Most well-known extruders on the market
Material: Tool steel, HIP, stainless steel, nickel-based alloy, cobalt-based alloy, etc.
Properties: Wear-resisting, Corrode-resisting and Durable
Structural Features:
This unique modular screw block features three interruptions within a single pitch, forming an irregular trapezoidal kneading section. Corresponding to the gaps created by these interruptions, three rows of kneading pins are evenly arranged on the barrel liner. The positions of the screw blocks and pins are precisely matched, together constituting the core structure for enhanced mixing. The screw blocks adopt an overall modular design, allowing quick assembly with other threaded elements and adapting to extrusion equipment of different specifications.
Functions:
Auxiliary Fastening and Force Transmission
Through micro-deformation of its own, it evenly distributes locking force to the end face of threaded elements, preventing loosening caused by excessive local stress and reinforcing connection stability.
Sealing Protection
Fills gaps at connection points to block leakage of molten materials, prevents intrusion of external impurities, and ensures the cleanliness of material processing.
Positioning and Gap Adjustment
Aids in adjusting the axial position of components via its own thickness, ensuring precise installation and avoiding component interference.
Application Scenarios:
Primarily used between screw heads and threaded elements in twin-screw extruders, serving as a key auxiliary component for their connection.
Suitable for connection scenarios of metal parts requiring fastening, sealing, and positioning, particularly adaptable to high-temperature and high-pressure extrusion processing environments.
