Product Description
This combine harvester threshing auger cone, also known as a feeder drum inlet cone or spiral auger end cone, is a precision-formed sheet metal component that guides crop flow into the threshing or feeding section. The welded spiral body and mounting flanges provide strength and accurate alignment during high-speed harvesting.
We manufacture these cones as OEM replacement or custom-fit parts for combine harvester manufacturers and aftermarket distributors. Cone diameter, height, spiral pitch, flange hole pattern, and material thickness can all be customized to your drawing or sample.

FAQ
- Q1: What is this auger cone used for?
- A: This cone is installed at the inlet or end of a combine harvester feeder drum or threshing auger. It guides crop flow smoothly into the threshing or conveying section and helps prevent crop blockage.
- Q2: Can you make auger cones for specific harvester brands?
- A: Yes. We accept OEM orders based on your brand, model, drawing, or sample. If drawings are unavailable, we can reverse-engineer from photos or physical samples.
- Q3: What materials are used?
- A: We typically use Q235 or Q345 structural steel plate. For high-wear applications, we can use wear-resistant steel grades to extend service life.
- Q4: Can I customize the cone dimensions and hole pattern?
- A: Yes. Top diameter, bottom diameter, overall height, wall thickness, spiral pitch, and mounting flange hole pattern can all be customized to match your machine.
- Q5: What is your minimum order quantity?
- A: For standard designs, our MOQ is usually 10–20 pieces. For large custom cones, we can discuss based on tooling and production setup cost.
- Q6: How do you control forming accuracy?
- A: We use CNC rolling and forming equipment, followed by fixture welding and dimensional inspection. This ensures consistent cone geometry and correct flange alignment.
- Q7: What surface finish do you recommend?
- A: Spray painting or powder coating is suitable for normal field conditions. For humid or corrosive environments, we recommend hot-dip galvanizing (HDG) to AS/NZS 4680.
- Q8: How long is the lead time?
- A: Samples usually take 15–25 days after drawing confirmation. Bulk production lead time is typically 25–40 days depending on quantity and surface treatment.
- Q9: Do you provide full feeder drum assemblies?
- A: Yes. Besides individual cones, we also supply complete feeder drum assemblies, threshing drum assemblies, and related sheet metal fabricated parts.
- Q10: How do I request a quote?
- A: Please send us the product drawing or sample photo, quantity, material requirement, color, and destination port. Our sales team will reply within 24 hours with a detailed quotation.
