Import Auto Stamping Dies — Buy in wholesale FOB from Supplier in China

Tj Innova Engineering & Technology Co., Ltd. manufactures auto stamping dies for forming automotive body panels and chassis components from sheet metal at its facility in Wuxi, China. The dies are engineered for high-speed press lines and manufactured from tool steels including A2, D2 and H13 grades, selected for wear resistance and thermal stability under repeated impact loading. These precision tools are used to produce outer body parts such as doors, roofs, side-panels and hoods, as well as structural chassis components including cross-members and bracket assemblies. The supplier also produces dies for inner body parts including wheelhouses, floor panels and seat reinforcements, alongside testing jigs and welding fixtures.

Tool steel selection follows standard automotive die practice: A2 offers air-hardening convenience with good dimensional stability; D2 provides superior abrasion resistance for long production runs; H13 delivers excellent toughness and resistance to thermal fatigue for hot-forming or high-speed applications. Die cavities and cutting edges are typically hardened to 58-62 HRC for A2/D2 and 48-52 HRC for H13, though exact hardness values for Tj Innova's output should be confirmed with the supplier. Standard industry tolerances for automotive stamping dies range from plus-or-minus 0.02 mm for critical contour surfaces to plus-or-minus 0.1 mm for secondary features, depending on part class and OEM customer requirements. Die life expectancy typically spans 500,000 to 2,000,000 strokes before major reconditioning, contingent on material thickness, part complexity and press line speed.

Buyers for these dies include OEM manufacturers and tier-one automotive suppliers operating press shops with mechanical or servo-driven stamping lines. Typical applications span closure panels, structural reinforcements and chassis brackets for passenger vehicles and light commercial vehicles. The dies represent capital equipment rather than consumable parts, with individual die sets often exceeding 10 tonnes in mass for large body-panel tools. Press tonnage requirements range from 800 to 6,000 kN for single-action dies and 10,000 to 25,000 kN for transfer press tooling, typical values that buyers must match to their existing equipment. Importing from Wuxi, China involves confirming die design standards (commonly VW, GM or Toyota specifications), acceptance testing protocols, and whether the supplier provides full tryout and spotting services before shipment.

Tj Innova Engineering & Technology Co., Ltd. is located at C Building, No.100, Dicui Road, Wuxi 214072, China, in the Jiangsu province manufacturing corridor. The supplier is classified as an imported tier vendor within the marketplace system and holds a harbor trust tier designation. The response rate is listed at 0.00 with zero average response hours recorded, which indicates no response data is available rather than zero actual responses. Buyers should note that verification signals are limited and direct contact is essential to assess current production capacity and engineering support.

The company produces auto stamping dies for outer body panels Mits, inner structural parts and chassis components, extending its offering to testing jigs and welding fixtures. The listing explicitly states these products are not limited to the automotive industry, suggesting capability in adjacent sectors. No information is provided about year of establishment, factory floor area, employee count, annual revenue, specific OEM customers, or ISO quality certifications. Buyers should request evidence of quality management system certification, previous die project references, and whether in-house CNC machining and heat treatment capabilities are owned or subcontracted.
