The four-roll hydraulic forming machine is characterized by high output, because the finished parts are formed at one time, and the operation is convenient and comfortable.

The W12 model is one of the highest quality products on the market. Hydraulic motors with planetary gearboxes for the upper and lower rollers of W12 model provide power, which directly transmits the power to the rollers without losing power.

The rolls are made of high-quality forged steel, which is induction tempered and quenched. After quenching, we polish the rolls. We also provide special rolls for certain jobs upon request.

We use double spherical roller bearings instead of bushings to eliminate bushing tolerances and friction, resulting in energy loss.

The bearings are pre-lubricated and protected by a special gasket, which does not require any lubrication during the entire service life of the machine

The four-roll machine has several advantages:

We can gently clamp the sheet between the two center rollers in the process of pressing the flat sheet, and lift the rear roller up to help.

Better pre-rolling performance, because we can clamp the work piece firmly between the two center rollers during pre-rolling, thereby eliminating work piece slippage.

Since the workpiece is firmly clamped during the pre-rolling operation, a smaller flat end can be produced. This leads to in many cases, no additional operations are required before seam welding of the parts.
