Stefa Folding Machine VH

Mac-Tech’s long folding machines stand out for their precision, cost effectiveness and state of the art versatility for easy operation. Using the unique bending beam technology, Mac-Tech’s long folders produces a rotation against the material that is clamped by the beam. This allows for working with the most delicate of surfaces without damaging the product, as is typically the case with thinner (between 0.5 to 0.8mm) coated and lacquered material and depending on the number of arms the Mac-Tech long folder can bend thick materials up to 3mm.

The perfect metal folding machine for 3m to 12mm in length, lengths that a press brake simply can’t produce. Long lengths can be achieved without extra additional add-on equipment. In addition, with a small footprint this folding machine can fit in spaces a press brake can’t.

Production Speeds

With the Mac-Tech long folding machine, tool configuration times are greatly reduced since there are no punches or dies, making it easy for the operator to start the machine and obtain an excellent finished product. These characteristics make this machine ideal to produce many profiles in small batches. With the depth of work that this machine can achieve it opens the door to handle much larger plates. Positioning becomes an uncomplicated task since the large part of the plate is supported on trays and “inside” the machine which frees up the operator and reduces fatigue.

Regardless of material thickness, radius, angle or sheet quality, there is no need to pre-set tools in a folding machine. Non-use of tools avoids maintenance costs and purchase of new ones. The geometry of the clamping beam allows you to perform rounds, hems, ‘tear droop’ hem or open hem without the tooling costs.

The Mac-Tech long folder comes standing with a automated cutting sheer. The flexibility to cut the entire length of the machine with a single piece of equipment reduces your overall cost per part. The two laminar slitting disks allow for smooth and burr free cuts every time.

Just In Time Manufacturing

Need to produce a part in hurry? With the simple CNC controller. Simply draw out your measurements and your ready to start running the job. The material development calculation is automatically performed, and the operator can begin prepping the next job.

Safety

As with any piece of equipment, operator safety is top of mind. The cost can be overwhelming with expensive safety lasers which does not prevent the machine from being safe. The Mac-Tech long folder ensures that the operator is always alerted to crushing and injury potential, with automatic safety alerts the machine does not allow automatic movements without the operators input first.
