About Us
Company Profile
Suzhou Rijiaxing Special Steel Co., Ltd. was established in 1993. The company is located in the picturesque town of Xukou, Suzhou, on the shores of beautiful Lake Taihu. We specialize in hot-work die steel, cold-work die steel, high-speed steel, copper, and aluminum.
Equipped with high-precision CNC machining equipment, we provide our customers with superior quality and meet their exacting machining requirements. Through our tireless efforts over the years, we have earned the trust of customers in both domestic and international markets and have become a leading supplier of mold steel to many renowned brands.
For many years, the company has maintained close cooperation with three international steel mills—DAIDO (Japan), SCANA (Sweden), and SIJ (Germany)—and is authorized to serve the Chinese market on their behalf. At the same time, we have long provided promotional and service support for leading domestic mold steel manufacturers such as Fushun Iron & Steel, Baosteel, and Zhiwei.
We look forward to working hand in hand with you through concrete actions, collaborating in good faith to create a brilliant future together!
STAMPING
The stamping facility runs 25 mechanical and hydraulic press machines from 60T to 1000T capacity. Worktables span 500×400 mm to 4000×1500 mm, with closed heights of 230-900 mm and slide strokes of 135-800 mm. The press line handles cold-rolled, stainless, and galvanized steel sheet from 0.15 mm to 6.0 mm thickness, with material widths up to 1000 mm and automated straightener-feeder systems or robotic transfer arms on most cells. Press types include single-point and double-point mechanical presses plus 1 hydraulic press for deep-draw work. Production runs at a sustained 75% utilization rate on 12-hour shifts. Capabilities cover progressive-die stamping, single-operation blanking and forming, and tandem-press transfer of large automotive body components. Typical products include accelerator-pedal brackets, brake-pump supports, window-lift hinges, friction plates, sheet-metal shields, and safety-critical structural parts, with full IATF 16949 quality-system compliance and in-line CMM inspection.
MOLD
The mold-making division operates 16 categories of precision tooling equipment totaling 43 machines. Highlights include slow-wire EDM at ±0.002 mm precision (travel600×400×320 mm), 11 sets of mid/fast-wire EDM (travel 630×400×350 mm), small-hole and forming EDM, surface and cylindrical grinders, jig borers, lathes, and radial drills. CNC machining centers reach travels of 3200×2200×1000 mm with positioning accuracy of 0.01 mm, while a Baoma profile projector inspects at 0.001 mm resolution. A dedicated 200T gantry tryout press validates die performance before release. The facility designs and builds progressive stamping dies, single-process dies, compound dies, and plastic injection molds for automotive, security-camera, aerospace-display, and industrial-enclosure applications, processing PC, PC+ABS, ABS, PA66+GF35, PA66+GF20, and PP resins. Tooling is fully CMM-verified against IATF 16949 tolerances before shipment。
