JB21 JB21S Series C-Frame Press

Product Features
Due to superior quality steel plate and welded steel structure, the C-frame press offers high structural stability. It also has stable transmission and features rational structure design due to its horizontally displaced crankshaft and the drive system positioned on either side of the machine.

For the purpose of minimized noise and enhanced safety, this mechanical press adopts dry type pneumatic friction clutch. The safety of the machine and press tooling is further guaranteed by a specialized protection unit.

Our JB21 and JB21S series C-frame press products are PLC centralized controlled, and can be optionally equipped with air cushion, automatic feeder, transmission output shaft, and photoelectric protector.

To satisfy clients' individual demands, this range of metal forming press is fabricated with different structures. Our C-frame presses of JB21/JB21S-100 to JB21/JB21S-200 models are designed with six-surface slide guide, pneumatic balance cylinder, and electric die set height adjustment function.

By exchanging the press tooling, the machine can be utilized for punching, blanking, bending forming, and more purposes. Combining the functions of punch press, blanking press, press brake, etc., this sheet metal machinery offers you a great solution for processing sheet metals in automotive, home appliance, and more industries.
