ipm [ on cover ] Automated belling machines for extrusion lines to process corrugated pipes of polyethylene and polypropylene. Direct socket formation onto the pipe by injection moulding. Socket features: perfectly welded, mechanically stable, aesthetically attractive with even, uniform surfaces. Italian technology plast / October 2013 The BA 680/INJ pipe belling machine is designed to injection mould sockets directly on double-wall corrugated pipes Die BA 680/INJ Muffenmaschine für Muffenformung mit Spritzverfahren direkt an Doppelwand-Wellenrohren Corrugated pipe belling technology Even in such challenging economic times as these, in 2012 IPM was able to increase its market share around the world both in terms of development – a witness to the company’s research program, ongoing commitment, passion and professional expertise – and the quality and reliability of the machinery it manufactures. From this point of view, 2012 saw the successful introduction of an innovative range of INJ pipe belling machines for extrusion lines. These machines are completely automatic and are used to injection mould the socket directly onto double-wall corrugated pipes. The versatility of INJ machines is noteworthy as they can process polyethylene and polypropylene equally well using the same equipment. This ambitious project, which took years of research in partnership with the University of Bologna, has led to new, patented technology able to operate with the fastest corrugated pipe extrusion lines currently available on the market. This machine can produce from 90 sockets per hour (pipe OD 110mm) to 25 sockets per hour on pipes with OD of 500mm, but more than this, the machine drastically reduces defects and rejects by increasing the quality of the socket to extremely high levels, and guaranteeing absolute geometric and dimensional stability that will last over time. There are currently four different models in production: for pipes up to six metres long (a 12-meter version can be supplied on request), which are as follows: BA 500 INJ for outside diameters: 110-500mm, BA 680 INJ for OD 160-680 mm, BA 900 INJ for OD 160-900 mm and BA 1200 INJ for OD 200-1200 mm. It is vital that the socket be made of the same material (polyethylene or polypropylene) as the pipe, thereby preventing retraction and any problems linked to “memory effect”, which more traditional thermoforming methods are prone to. This new process is able to ensure reliability, absolute dimensional stability for long periods of time (whatever the ambient temperature), and above all the production cycle can be repeated easily with different raw materials and multiple moulding shapes. Furthermore, the ovalisation defects that may occur in the pipe will have no effect on the socket and the socket walls can be made thicker, the socket shape can be personalised freely and customers can even add their logo if they wish. Tests and the microscopic electro-analysis carried out (and demonstrated by certification from the University of Bologna) show that injected sockets are more resistant than the pipe itself; they are perfectly welded, mechanically stable, aesthetically attractive and offer even, uniform surfaces. As well as in-line belling, such systems offer the customer the option of manufacturing double joint pieces in variable lengths. There are a number of advantages when compared to other systems currently available on the market and here we list the main differences. - “friction” type joints with fitting. The IPM system totally eliminates the following problems: - roduction rejects due to incorrect or incomplete fitting welding p onto the pipe - time and money spent on detecting defects in the socket weld - need for fitting storage, resulting in remarkable room saving - manual handling and feeding of fittings r - eliance on subcontractors supplying fittings and possible variations in price www.plast
