Machines that mould sockets on bioriented PVC or PP pipes

The market trend towards the use of what are thought to be more eco-friendly polyolefin resins and lighter and less costly materials has revolutionised socket-moulding machine technology, and consequently the most recently marketed belling machines have a number of new features.

Of particular interest are the machines that mould sockets on bioriented PVC or PP pipes and, thanks to the innovative SICA patented “Permanent Socket Profile” (PSP) system, it is now possible to socket corrugated and ultrarib PP pipes and multi-layer PP pipes. These materials, although interesting, require more sophisticated socketing systems as they have a mechanical memory that affects shrinkage after the moulding of the socket. The PSP system can be used for in-line socketing and makes the socket immune to spontaneous shrinkage even after prolonged exposure to atmospheric agents.
Also worth noting is a new belling machine model for PP, PE and PVC, the BA/PP/1T 160 H version (high capacity) for pipes of diameter 32 mm to 160 mm inclusive. This machine, tried and tested with 250 models installed and working all over the world, has been upgraded to give increased performance. The result is a more compact belling machine with an increased production capacity. It can produce more than 800 sockets an hour on PVC pipe of thickness 1.8 mm and over 680 sockets an hour on PP pipes of thickness 1.8 mm. High speed operations such as these call for high reliability, and this is guaranteed with a series of SICA patented process solutions.
