Press line

Chipboards are manufactured in a continuously operating press system. The compression force is generated by a hundred press cylinders arranged one after the other. Cylinder distortions can occur during operation however and these often cause the static seal of the threaded locking ring to leak.

Based on the damage analysis in the context of the repair, Montanhydraulik Reparatur und Service GmbH retrofitted the press cylinder with a flanged locking ring in order to relocate the static sealing to an area of low deformation.

Further advantages of the retrofitting include the guarantee of the tightness even in the case of major distortions plus simple and rapid disassembly of the locking ring for repair.

Press cylinder:

  • piston diameter: 327.5 mm
  • rod diameter: 300 mm
  • stroke: 110 mm
