Extrusion system for large-wall tube and pipe

Proven performance for sanitary pressure pipes

Sabic Europe, The Netherlands, is a supplier of pipe grades in bimodal HDPE and various PP grades. The company’s Vestolen P 9421 is a PP random copolymer (PPR) grade used in applications such as hot and cold water supply. This grade of pressure pipes has been in use for over 30 years, which is claimed to be longer than any other PPR pipe grade. Vestolen P 9421 is available in a variety of colours and contains a finely tuned stabilisation package proven to be fully effective against thermo-oxidative

degradation. Pipes produced from the grade meet the requirements of the commonly used ISO EN 15874 and ISO 3213 standards. Vestolen P 9421 is easy to handle and process using conventional extruders and injection moulding machines. It is also environmentally friendly and corrosion- free.

Guill Tool & Engineering, USA, has extended its new 200 Series extrusion system to handle sizes of up to 20" in diameter and up to 2" wall size thicknesses. The new 200 series is a self-contained extrusion system weighing as much as 7,000lbs. The system has a patent pending mounted track and cart for easy handling and maintenance. The cart system can tilt the die on-the-fly in order to compensate for the catenary (sagging) effect caused by gravity as the extrusion product exits the equipment.

Tube bending,

as it should be.

More productivity and precision… Less set-up time and scrap

Cable, tube or pipe manufacturers that require large diameter and multi-layer jacketing will also benefit from the new rapid advanced material flow of the 200 extrusion head and the support system, without the rigging or support equipment usually required by conventional systems on the market today. With Guill’s precision engineering, the 200 Series ensures thinner walls and closer tolerances. This is important for larger tubing sizes, where waste or scrap may account for thousands of dollars in lost revenue. Engineering for the closest tubing tolerances results in huge material savings for all users, according to Guill production officials. The company also manufacturers tips, dies, and breaker plates.

Unison’s all-electric tube bending machines will revolutionise your tube fabrication operations. Servomotor bending axes give you complete software control of the process. You can bend with enormous precision. Scrap is virtually eliminated! And anyone can set- up the machine automatically, and repeat configurations at will. The all-electric machine will also slash your electricity costs, as it only consumes significant energy when actually making a bend. On a customer comparison with an equivalent hydraulic bender, our machine consumed 90% less electricity! Choose Unison - the inventor of the all-electric tube bender - and you will see a genuine return on your machinery investment. We have a large range of machines for 10 to 150 mm diameter tubes.
