STN series is Straight Side Tie Rod Frame 2-Point & 4-Point Mechanical Eccentric Gear Press Machine.
This series presses are large stroke length,which are great for large stamping parts. Application such as appliances panels or automotive body panels parts are commonly stamped on these press machine. It can also be used on any type of application where long forming or drawing is required. It is common that in the production it would requires robotic system or 3-axis transfer systems devices to transfer parts between presses, so the long stroke also serve as time window for the parts handling systems. QIAOSEN STN Press is great for large progressive stamping, through the windows 3-axis transfer stamping, and press to press robotic integrated applications.
STN series presses are produced by Qiaosen machinery, which built to meet or exceed JIS Class 1 accuracy standards. Qiaosen adopt high strength steel frames and Quenching & Grinding Process for Slide-Guide,which can make the press machine have minimizing deflection and high accuracy and provide increased tool life.
Forged 42CrMo alloy material crankshaft ,precision-machined gears and other drive train components are designed for smooth power transmission, quiet operation and long life. Qiaosen adopts "8-Points Slide Guiding" ,its makes the presses has the characteristics higher accuracy and stronger stability. It Can be option equipped with Die Doors, Quick Die Change System, and Moving Bolster to make production safer, more efficient, and more convenient.
