Description
Manufacturing Process
- Material Selection – High-carbon steel or alloy steel is chosen for strength and wear resistance.
- Cutting & Shaping – Steel bars are cut and formed into the required rasp bar shape.
- Teeth Formation – Teeth or ridges are either cast, milled, or welded onto the bar for effective threshing.
- Heat Treatment – Hardening and tempering enhance durability and resistance to wear.
- Surface Coating – Protective coatings (e.g., powder coating, zinc plating) prevent corrosion.
- Quality Testing – The bars undergo hardness tests, wear resistance checks, and dimensional inspections before final use.
