Custom Auger Screw Manufacturing and Assembly

Auger screws are essential in material handling across a variety of industries. Their effectiveness depends on precise manufacturing, expert fabrication, and meticulous assembly. At Falcon, we manage each phase from flight forming, machining and welding to the final assembly, delivering a ready-to-install product that performs dependably.

Flighting Only or Full Assembly: Choose What You Need

Customers can choose to buy just the flight from us or a fully assembled auger screw, depending on their in-house capabilities. While many facilities can handle welding and machining, producing a true helical flight requires specialized equipment and expertise to maintain consistent pitch, shape and overall quality.

Some customers only need a replacement flight for their own fabrication work, while others want a complete auger screw assembly, so they don’t have to do any production themselves.

Often, customers are capable of fabricating parts in-house but still choose to outsource the full assembly. This approach can help reduce labor requirements, avoid production delays, and maintain consistent quality without depleting their own resources.

How Falcon Assembles Custom Auger Screws

A correct auger screw assembly starts with one critical input: knowing what the flighting will attach to whether it be a shaft, pipe, or tube. This determines all primary dimensions before production begins.

During production, Falcon uses fixtures and alignment tools to ensure each helical flight section achieves the correct inside diameter and pitch. Before moving to assembly, every section is checked against the shaft or pipe it will fit on to ensure proper alignment and fit-up.

Consistent metal flow during the forming process is equally important. Because twisting steel can alter the shape of a flight, the flow side of each section is marked. This marking ensures correct orientation during assembly and prevents misalignment or fit issues in the final product.

Quality Checks at Every Stage

Falcon performs quality checks throughout production regardless of whether the order is for full assembly or flight only. Key fit-up and quality considerations include:

• Verifying inside diameter, outside diameter, and pitch across the full assembly
• Confirming alignment between sectional flight components
• Checking bolt-on wear shoes against customer-provided samples
• Matching customer-supplied shafts, pipes, or tubes for accurate fit-up

When customers provide parts such as cones or tapered shafts, having the actual component on hand enables direct test-fitting for precise inspection. When not available, alternative estimation methods are used, but direct matching remains the most reliable way to confirm accuracy.

Custom Auger Screw Configurations and Specifications

Every auger screw is custom-built. Each design responds directly to customer drawings, specifications, or collaborative input.

Common customization features include:

• Shaft types: round shaft with keyway, square shaft, or splined shafts
• Flight materials: carbon steel, stainless steel, or abrasion-resistant alloys
• Size range: can be up to 20 to 30 feet in length and 6 feet in diameter, with larger sizes possible depending on our equipment capacity
• Multi-section designs: used for long auger screw systems needing sectional assembly
• Handling limits: usually about 1 ton per hoist, with higher capacity possible using overhead crane systems

Sometimes, very large auger screw assemblies exceed our in-house handling limits. In these cases, production may be moved to another one of our facilities. For oversized systems, final assembly might be outsourced, but Falcon still manages the quality standards.

Lead times generally depend on the job’s complexity. We usually provide quotes quickly after getting the needed information, but complete fabrication and assembly can take anywhere from a couple of weeks to more than a month, depending on machining requirements, design complexity, and material availability.

Auger Screw Applications Across Industries

Auger screws are used across many industries, and each application brings its own design requirements that influence performance, durability and overall construction.

Major considerations include:

• Wear protection: hard-facing or wear coatings for abrasive materials
• Orientation design: differences between horizontal (parallel to the ground), inclined (at an angle), and vertical (upright position) systems

Industries that rely on auger screws include:

• Agriculture: Grain bag storage, feed screws, and silo unloaders.
• Construction: Grout pumps and piling augers.
• Wastewater and Environmental: Air pollution control systems, and trash compactors.
• Mining and Drilling: Drill rigs and sand washers.
• Food Preparation: Bakery screws, meat processing screws, and ice cream mixers.
• Pulp and Paper: Turbulence enhancers, conveyors, and dewatering screws.
• Chemicals: Centrifuges, mixers, and blending systems.

Across all industries, auger screws must not only convey material but also stay aligned, operate continuously, and remain dependable under actual operating conditions.

Built for Fit, Performance, and Reliability

The performance of a custom auger screw depends on precise alignment, accurate fit, and disciplined attention to detail at every stage of fabrication and assembly. Falcon Industries applies the same standards whether delivering replacement flight or a fully assembled auger screw: to deliver a product that fits precisely, performs consistently, and runs right from the start.
