Dongri Technology Successfully Delivers 3000-Ton TRF Multi-Station Stamping Die, Setting New Benchmark in Automotive Stamping Industry

Recently, Maidi Mold Co., Ltd., a subsidiary of Dongri Technology Group, announced a major achievement—eight customized 3000-ton TRF multi-station stamping dies tailored for a globally renowned Japanese automotive parts supplier have completed full-process debugging and achieved stable mass production at the client’s Guangzhou production base. This delivery project not only includes an integrated precision mold system solution but also incorporates fully automated robotic arm integration, reaffirming Dongri Technology’s exceptional capabilities in ultra-high-strength automotive stamping molds.

Overcoming Technical Barriers of Ultra-Hard Materials, Establishing Industry Standards

The technical challenges of this project centered on the forming process of two ultra-high-strength steel plates: SPC1180DUB and SCGA1180DUB-45. With hardness levels reaching 1180MPa and elongation rates as low as 5%-7%, traditional molds face industry-wide issues such as forming cracks and springback control. Maidi Mold’s R&D team leveraged its proprietary "Multi-stage Variable Clearance Compensation Technology" and a self-developed mold stress simulation system to successfully control component dimensional tolerances within ±0.08mm, achieving a 40% improvement over industry standards.

Intelligent Mold System Empowers Automotive Lightweighting

The TRF multi-station stamping mold system integrates intelligent temperature control, online inspection modules, and robotic automation transfer systems, enabling high-efficiency production at 20 strokes per minute. The specially designed six-station progressive die structure consolidates 24 traditional processes for automotive floor frame components into 5 continuous forming steps, boosting material utilization to 92% and driving cost-effective production for clients. Mass-produced components have passed customer’s global quality certification and will be used in TOYOTA 313D vehicle models.

Two Decades of Expertise Forging Core Competitiveness

As an outstanding enterprise recognized by the China Automotive Industry Association, Dongri Technology has dedicated 20 years to automotive stamping mold R&D, accumulating 37 patented stamping forming technologies. The company operates Asia’s leading 20,000kN-class mold testing center, equipped with German-imported five-axis machining clusters, offering end-to-end services from CAE analysis and mold development to production line integration. The successful delivery of this 3000-ton project reaffirms Dongri’s leadership in high-tonnage stamping equipment and ultra-high-strength material forming.

“This is a milestone project in automotive chassis structural components,” stated Dongri Technology’s Chief Technology Officer. “With the growing demand for lightweighting in new energy vehicles, we are accelerating R&D for 8,000kN-class multi-station stamping molds. We expect to launch an intelligent mold system compatible with 1,500MPa-grade ultra-high-strength steel by 2025.”
