Pressure grouting machine – SF50

The pressure grouting machine SF50 - segment forming machine - is used for:

  • grouting / pressing of shells with cables or sleeves
  • grouting / pressing of cases with plugs
  • grouting / pressing of sleeves and pipes
  • grouting / pressing of sensors with cables 


The motorised press guarantees a form-fit connection which helps achieve, among other things, better strain-relief, anti-twist protection or shielding.  

For workers of rotationally symmetric components the segment forming machine SF50 represents a consistent enhancement of existing systems for the pressing of pipes, pipe ends, sleeves, shells, armatures and many other applications. 

A typical example is the implementation of sensor sleeves which mechanically protect connection leads from being pulled out and seal them at the same time. This procedure also allows crimping of plugs into sensor sleeves. Wall thicknesses of 1.0 mm up to approx. 2.0 mm with a diameter of 3 – 50 mm are possible.

Machine setup

The handling of the pressure grouting machine is very simple. The work piece is inserted into the opening, usually positioned with the help of a stopper, which assures that it does not move while the jaws move axially towards the work piece. The corresponding working parameters can be stored and managed in the machine control system. The user interface allows easy and logical operation. All essential processes are electronically monitored and the data is stored in the control system. This ensures high process safety and reproducibility.

Basic machine

  • basic module with fastening holes for the reception of all functional components consists of: base panel with carrier for servomotor, gearing and encoder
  • setup consisting of connecting member, lever and jaw guide conduct
  • jaws (forming tools), flat or circular press, possible number of jaws: 8
