Product Introduction

The tonnage capacity starts from 300 ton up to 1200 ton. The press is constructed with welded heavy boxed type frames, and it is pressurized with tie rods to 150% of press capacity for better deflection rating. Our center drive design maximizes the transmission performance and reduce inertias, which increase the service life of the press. STF series presses is great for large progressive stamping, through the windows 3-axis transfer stamping, and press to press robotic integrated applications.

STF series presses are produced by company, which built to meet or exceed JIS Class 1 accuracy standards. 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. Presses below 600 tons use pneumatic wet clutch brakes (unibody), while presses above 800 tons use dry clutch brakes (split-type). Adopting “8-Points Slide Guiding” ,its makes the presses has the characteristics higher accuracy and stronger stability.

Can be option equipped with Die Doors, Quick Die Change System, and Moving Bolster to make production safer, more efficient, and more convenient.
