Product Range and Specialties of Ningbo Tuoxing Precision Casting Co., Ltd.

The catalogue comprises five distinct bucket‑tooth and adapter items designed for Caterpillar excavators: Cat 1u3252 bucket teeth, Tiger Teeth 1U3202TL, casting bucket teeth and adaptors CAT330, bucket teeth 4K6936, and bucket adapter 1U3352/1U3302. These components are typically forged from high‑strength alloy steel such as AISI 4140 or 4340, subsequently heat‑treated to a hardness range of 45‑55 HRC and surface‑treated with carbide or chrome plating for wear resistance. Standard dimensions follow OEM specifications, with tooth width between 60 mm and 80 mm and shank diameters around 30 mm, and adapters are machined to match the bucket mounting pattern of the respective model. In the excavator spare‑part market, buyers often request material test certificates, hardness reports, and dimensional inspection reports (e.g., CMM data) before confirming orders.

Trade and Export Information - Ningbo Tuoxing Precision Casting Co., Ltd.

China is a major exporter of heavy‑equipment components, and suppliers of bucket teeth typically ship to construction equipment manufacturers and aftermarket distributors in North America, Europe, the Middle East, and Southeast Asia. The relevant HS heading for such parts is 8465 90 (parts of machines for earth‑moving). Commonly required certifications include ISO 9001 for quality management, ISO 14001 for environmental management, and, where applicable, CE marking for EU market entry. Export shipments are usually packed in wooden crates or bulk bags, loaded in 20‑foot or 40‑foot containers, and traded under FOB Ningbo or CIF destination ports. Chinese export regulations require a commercial invoice, packing list, certificate of origin, and, for steel parts, a material safety data sheet.

Sourcing from Ningbo Tuoxing Precision Casting Co., Ltd. - Buyer Guidance

Prospective buyers should request a sample batch together with a mill test report (MTR) that confirms chemical composition and mechanical properties such as tensile strength (≥ 800 MPa) and impact energy (≥ 27 J). Verification of the supplier’s ISO 9001 certification and recent factory audit reports helps assess production consistency. Buyers typically specify the required hardness (e.g., 48 ± 2 HRC) and any surface coating (e.g., 0.5 mm carbide wear plate) in the purchase order, and confirm packaging details - standard practice is individual wooden boxes within a master crate. Lead times for forged bucket teeth in China range from 30 to 45 days after receipt of a confirmed order and payment terms are usually T/T or L/C.
