product update | Applications INDUSTRIAL PA66 gas cylinder guard replaces steel
UK-based moulder Glazpart is using an Akromid A3 PA6,6 compound from Akro-Plastic to produce an innovative injection moulded industrial gas cylinder protection guard that replaces an existing steel design. This is an extremely demanding
application, says Akro-Plastic. Each cylinder weighs 100kg and the guard must withstand a 1.2m drop test onto a hard surface at temperatures between -40˚C and +65˚C. Plastic guards have been used on
industrial gas cylinders weighing up to 50kg but this is said to be the first
AUTOMOTIVE TPE secures automotive lines
Automotive systems supplier Veritas has selected Hipex thermoplastic elastomer from Kraiburg TPE for production of
two-component clips for securing brake lines in the engine compartment. The Hipex material was
chosen for its ability to withstand temperatures up to 150˚C and its resistance to oils and greases. It is also compatible with the polyamide resin used for the body of the clips (a mechanical anchoring
technique is used). ENGINEERING Winzeler gears up with five Engel machines
US-based technical moulder Winzeler Gear has added a further five Engel e-Victory machines to its highly automated production facility in Chicago in the US. The new equipment (four 65
tonne e-Victory 200/65 and one 160 tonne e-Victory 740/160) take the moulder’s machine

park up to 39, more than half tiebar-less Engel designs. “The Engel tie-bar-less
design provides us with the ultimate flexibility when designing our automation,” says John Winzeler, president of Winzeler Gear. “The moulding plant dynamics would be changed completely

if we had to rely on conven- tional machine designs.” Winzeler uses a combina- tion of linear and six-axis robots to automate its production systems, along with automated box loading with bar coding traceability. The aim is to ensure consistency of production and eliminate
human intervention at the plant, which produces some 120m gears annually. The company also uses
Engel’s quick mould change system, which it has combined with its own design mould cart. ❙

Veritas to develop the clip, providing advice at the design stage through to volume production. “We are con- vinced that HIPEX will become a standard material for use in the engine compartment and transmis- sion”, says Dr Martin Geissinger, product manager at Kraiburg TPE. ❙

application on the larger 100kg types. It took two years to select the material and develop the component design, which has been compliance tested by the Brussels-based Apragaz certification body. The parts are manufactured in
Akromid A3 S1 Grey, a highly impact modified PA6,6 grade produced at the Akro-Plastic plant in Germany and supplied in the UK by K D Feddersen.
The guards are fitted during cylinder testing. Up to 300 are required per shift, calling for up to 30,000 each year in the UK. The steel guards previously used were produced in China and sup- plied in batches, which lead to occasional shortages.
Manufacturing in the UK is said to have eliminated this problem. ❙
