Integrated Non-Welded Stainless Steel Conveying Screw Augers

Key Features

One-Piece Integrated Forming, Zero Welding Joints

The shaft and spiral flight are machined as an integral single body with no welding points. No weld cracks, gaps or dead corners to trap powder, eliminating cross-contamination risks during material switching.

Food-Grade Stainless Steel Material

Fabricated from solid SUS304 stainless steel as standard; SUS316L is optional for corrosive materials. Smooth polished surface (mirror or satin matte finish available) resists powder adhesion and is easy to rinse and sanitize.

Customizable Screw Parameters

Multiple specifications including variable shaft diameters, spiral pitches, flight outer diameters and total lengths are available to match micro-dose, medium-dose and large-dose filling & conveying requirements. Thin-walled fine augers for tiny weighing, thick heavy-duty augers for high-volume transport.

High Structural Strength & Stable Operation

The seamless monolithic structure delivers superior rigidity compared to welded augers. It runs smoothly under servo drive with low vibration, ensuring long service life and consistent metering accuracy.

Sanitary, Residue-Free Design

Absence of welding crevices prevents powder buildup, caking and bacterial growth, fully complying with GMP hygiene standards for food, pharmaceutical and cosmetic production.

Wide CompatibilityInterchangeable with most brands of screw dosing heads, vertical screw elevators, powder filling machines and feeding conveyors, supporting quick replacement for production lines.
