Socketing machine- UNIBELL

A range of belling machines for PVC-U pipes that offer several configuration options and equipment to meet market demands in terms of production capacity for plastic pipe extrusion systems.

Versions with hot air oven, oven with ceramic elements, shortwave oven, and air or water socket cooling system.

Machines can be configured with one or two heating stations.

Advantages and key features:

  1. Reduced footprint and high productivity thanks to the use of a single IR-SW heating station and socket cooling system with internal cooling cycle (Sica patent), as well as a special ring loading system (Rieber R versions).
  2. Low energy consumption heating cycle with IR-SW oven. The heating station switches on only when the pipe is to be heated and power output is controlled by the temperature measured directly on the pipe surface.
  3. Low energy consumption socket forming cycle. The socket cooling fluid is recovered and used to cool the forming mandrel (Sica patent).
  4. High quality socket with excellent surface finish. The socket is formed and calibrated internally on the mandrel by compressed air. The socket is then cooled with filtered dry air.
  5. Reliable work process. Only filtered and dried air is used in the forming cycle, which means: simple system construction, easy component cleaning, and no corrosion.
  6. Versatility with a variety of machine configurations. Versions are available for the Rieber (R) system, as well as simplified versions only with mechanical mandrel and solvent-cement socket.
  7. Quick tool change for switching pipe diameter with both mechanical mandrel and Rieber systems, using patented Sica equipment.
  8. Sockets short pipes down to 0.5 meters on drainage pipe.
  9. High productivity version with two heating stations (/2) and cooling via compressed air mixed with pressurized atomized water (JW). Sica patent.
