Pressure grouting machine SF25 open

The pressure grouting machine SF25 open – segment forming machine - is used for the pressing of components with pinch points, which cannot be inserted into other machines:

  • cables with angle plugs
  • sensors with larger clamping flange
  • sleeves with longer tubes on both side
  • angled pipes

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 SF25 open 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 the crimping of plugs into sensor cases and much else. Suitable for wall thicknesses from 0.2 mm up to ca. 1.0 mm and a diameter of 3 – 25 mm, depending on the material.

Machine setup

The handling of the machine is very simple. The work piece is inserted into the opening. With this special form of segment forming machine, it is also possible to insert the work piece through an insertion slot at the side. The work piece is 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
