As a professional manufacturer of wear-resistant excavator components, we continuously optimize the production technology of our Forged Tooth Adapter to improve durability, impact resistance, and assembly precision for demanding mining and construction applications.
Our production begins with the selection of high-quality 42CrMo and 35CrMnSi alloy structural steel. Each material batch is carefully cut into fixed-length billets to ensure stable dimensions and defect-free raw materials before entering the forging stage.
During hot forging, the billets are heated to 1100–1200℃ using an intermediate frequency furnace and then formed through precision die forging. This process significantly refines the internal grain structure, increases metal density, and improves the tensile strength and toughness of the Forged Tooth Adapter, enabling it to withstand heavy excavation and high-impact working conditions.
After forging, the adapter blanks undergo rough machining, including profile milling, pin hole drilling, and root deburring. These procedures establish accurate assembly references for the following precision machining operations.
Heat treatment is one of the most critical manufacturing stages. We apply quenching and high-temperature tempering to achieve an ideal hardness range of HRC 28–35, ensuring an effective balance between strength and toughness. To further improve wear resistance, the pin hole surface receives induction hardening treatment, raising the surface hardness to HRC 50–58. This greatly enhances the durability of key contact areas under repeated impact and friction.
For dimensional accuracy, CNC boring and milling machines are used during finish machining. The fit clearance between the adapter, bucket tooth, and pin is controlled within 1.5mm, ensuring tight assembly, stable operation, and reduced looseness during long-term use.
To improve corrosion resistance, all Forged Tooth Adapter products undergo shot blasting to remove rust and slag before being coated with anti-rust primer and engineering-grade top paint. This protective treatment helps extend service life in harsh outdoor environments.
Before shipment, every product passes 100% dimensional inspection along with hardness testing, flaw detection, and assembly verification with DH360 bucket teeth. Only qualified products proceed to packaging, where anti-rust oil and moisture-proof protection are applied to ensure safe transportation and storage.
Through strict quality control and advanced forging technology, our Forged Tooth Adapter products provide reliable performance, longer service life, and stable operation for heavy-duty earthmoving and mining equipment.
