Mold clamping systems Hydraulic

Hydraulic mold clamping system QMC 100/101

Compact and robust: Stäubli hydraulic clamping systems are designed for a wide range of injection molding machines and presses. Even under harsh operating conditions, they meet all the requirements for a fast, automatic tool change. The hydraulic clamping devices are designed as single or double acting systems. Both clamping technology variants can be optimally integrated into the machine control. Your advantage: setup time optimization on machines of all manufacturers and sizes as well as new and existing plants (retrofit).

Product line overview

Hydraulic clamping system QMC 100 - single acting:

The tensioning element is prestressed by spring force and is hydraulically relieved by a pressure of 160 bar (released by single acting hydraulic cylinder).

  • Clamping system flexible and easily interchangeable
  • Connection of the hydraulic supply possible on both sides
  • Corrosion-resistant housing
  • Easily exchangeable, inductive proximity switches (for detecting the piston position taut / slack)
  • Mounting the proximity switches on the left or right side of the clamping element is possible
  • Self-locking clamping piston
  • Tool remains tensioned even in case of pressure loss

Hydraulic clamping system QMC 101 - double acting:

The tensioning element is tensioned with a hydraulic pressure of 80 bar and is relieved at 160 bar (clamping and release by double-acting hydraulic cylinders).'

  • Clamping system flexible and easily interchangeable
  • Connection of the hydraulic supply possible on both sides, further connections possible on request
  • Coated housing
  • Inductive proximity switches (taut / slack) for detecting the piston position
  • Proximity switches are recessed on the side and are easily interchangeable
  • Self-locking clamping piston
  • No change in the piston position on pressure loss
  • An integrated pressure piece of hardened steel transfers the clamping force only perpendicular to the tool plate


  • Clamping pistons made of high-alloy steel, hardened and ground
  • Clamping block made of surface treated steel
  • Seal made of NBR / FKM
  • Suitable for machine mounting plates with drilling pattern according to EUROMAP 2/3
