This design prevents off-center loading and edge warping even on large workpieces, significantly enhancing finished part accuracy from a hardware perspective. The entire machine features an all-welded closed-frame body made of steel plate, stress-relieved through aging treatment for superior vibration resistance and deformation stability. It supports continuous heavy-duty production for up to 24 hours, effectively extending mold life and substantially reducing...Metal stampingProduction Loss

Equipped with a core dry pneumatic clutch brake system and dual safety solenoid valves, this press delivers rapid braking response. It supports three operating modes: inching, single stroke, and continuous stamping, offering superior safety performance compared to traditional mechanical presses. The forged alloy crankshaft undergoes quenching and tempering for precision machining, paired with extended heavy-duty rectangular guide rails. This ensures minimal slider clearance and smooth operation, ideal for cutting and forming large sheets of cold-rolled steel, stainless steel, thick aluminum, and other materials. Full series.Dual-point Pneumatic PressCovers tonnage from 160T to 400T with a spacious worktable and standardized T-slot layout. Quickly install multi-station composite molds for punching, blanking, bending, and shallow drawing in one machine—ideal for flexible, multi-variety stamping production.

In terms of energy-saving and safety design, Shanghai YiduanHeavy-duty double-point pressEquipped with a pneumatic clutch for intermittent transmission, the motor consumes less power under no-load conditions. Compared to traditional rigid presses, it saves approximately 35% in energy while delivering smoother operation with reduced vibration and noise. The electrical control system features high-quality, nationally standardized components and includes dual-hand operation switches as standard. It also provides mounting positions for photoelectric safety devices and integrates overload protection, low-voltage alarms, and emergency stop functionality, fully complying with industrial safety regulations. With minimal wear-prone parts and straightforward maintenance, this equipment significantly reduces long-term operational costs, making it an ideal choice for technical upgrades in large-scale sheet metal fabrication facilities.Stamping Equipment。
