Product Introduction
STB series presses are produced by Qiaosen machinery.
The Qiaosen STB 1-point D frame press is designed for stamping small parts at high single-stroking rates or in continuous mode, using either blanks or coil stock. The STB metal stamping press provides all the features you expect to find in a world-class press, at a very competitive price, backed by a three-year (calendar-based) warranty without limitation.
It's different with gap frame press(ST-series),which added support beams that helps to reduce the spring back and add more rigidity to the press frame. It allows heavier duty works to be performed than on a c frame press machine.
Forged 42CrMo alloy material crankshaft, precision-machined gears and other drive train components are designed for smooth power transmission, quiet operation and long life. STB series presses are dry clutch system,It has longer service life of the clutch system, high single stroke rate and high torque outputs performance. Flywheel direct drive design, which can be customized to shorter stroke, more faster speed.
Qiaosen stamping press machines can be customized to meet a wider range of SPM, stroke, rating point (BDC), bed and other specifications and dimensions.
