Plastics & Food Machinery Thread Whirling Solutions

High-performance thread whirling for Plastics & Food Machinery. We machine deep-flight extruder screws and sanitary food-grade augers with flawless finishes.

Solving Extrusion & Conveying Bottlenecks

Forming Deep & Variable Pitches

Extruder screws often feature deep roots and complex variable pitches. Our macro-programmed whirling technology forms these massive, deep-flight profiles in a single pass, drastically reducing the endless cycles of conventional turning.

Achieving Sanitary Finishes

Food processing requires absolute hygiene. Our single-pass whirling creates a burr-free, Ra0.4 mirror finish straight off the machine. This eliminates material stagnation, prevents bacterial buildup, and strictly meets FDA sanitary standards.

Taming Wear-Resistant Metals

Plastics with glass fibers rapidly wear down screws. We excel at hard-whirling highly abrasive nitrided steels and bimetallic blanks, ensuring sharp flight edges and extended tool life without compromising the core's structural integrity.

Proven Expertise in Sanitary & Wear-Resistant Alloys

Whether handling highly abrasive polymers or strictly regulated food products, we match our cutting parameters to your industry's most demanding materials.

Food-Grade Stainless Steels (SUS316L / 304): Flawless, corrosion-resistant thread machining for meat grinders and sanitary augers, completely eliminating built-up edge (BUE) to guarantee absolute food safety.
Nitralloy & Bimetallic Steels (38CrMoAl): Optimized hard-whirling for injection molding screws, delivering exceptional wear resistance for processing glass-fiber-reinforced plastics.
High-Strength Tool Steels: Stable, high-feed machining for heavy-duty compounding twin-extruder shafts, maximizing both durability and production ROI.

Rigorous Inspection for Perfect Material Flow

Any deviation in flight depth or pitch can disrupt polymer melt pressure or food conveying volume. Our metrology lab ensures every screw profile meets your exact fluid dynamics requirements.

Deep Profile Verification: Using specialized depth micrometers and optical comparators to verify the exact geometry of deep roots, variable pitches, and complex mixing sections.
Surface Roughness Testing: Employing high-precision profilometers to strictly monitor Ra values, ensuring the ultra-smooth surfaces required for sanitary and anti-stagnation applications.
Full Material Certification: Providing complete mill test reports to guarantee compliance with your food-grade (FDA) or high-wear industrial specifications.
