Why Buy From Our Factory

• 20 years of OEM and ODM experience for bucket teeth and ground engaging tools; your drawings can become a production-ready casting.
• Free sample for fit verification before you commit to a container.
• Own foundry, not a trading desk — casting, heat treatment, machining and packing happen in one plant in Zhejiang, China, so we control the hardness curve instead of buying it in.
• 24-hour technical reply on part matching: send a photo, dimension sketch or machine serial and we confirm the tooth.

Packing and Delivery

Each tooth is wrapped in anti-rust paper, then packed in export-grade woven bags on a wooden pallet base, or in strong cartons for LCL shipments. Neutral packing is standard; your own carton print, label and pallet marking can be arranged on volume orders.

Application

Typical duty: road construction sub-grade ripping, pipeline trench preparation and land clearing, with a good balance between penetration and wear life.
