Frequently Asked Questions
What material thickness can ST-45 handle?
ST-45 is designed for 0.3–4mm cold rolled steel, galvanized sheet, stainless steel, copper and aluminum alloy. It supports blanking, light bending, embossing and shallow drawing, and is not applicable for plates thicker than 4mm or heavy deep drawing processes.
What's the difference between ST-25, ST-45 and ST-80 for tonnage selection?
- ST-25 (25 Ton): Mini high-speed model for 0.1–3mm ultra-thin foil and micro electronic parts
- ST-45 (45 Ton): Universal medium-small tonnage for 0.3–4mm medium-thin sheets with balanced speed, tonnage and cost
- ST-80 (80 Ton): Medium tonnage machine for 1–6mm sheets with stronger forming force
Can ST-45 be matched with automatic coil feeding lines?
Yes. The three-side open C-frame reserves standard mounting interfaces for NC servo roller feeders, uncoilers and straighteners, fully compatible with small multi-station progressive dies.
What safety interlock devices are equipped?
Complete safety system including multi-beam safety light curtain, hydraulic overload protection, dual-solenoid clutch anti-secondary drop interlock, emergency stop button, two-hand operation mode, and overload auto alarm.
