Engel has announced the winners of its 2015 HL Awards, which recognise companies using the Austrian group’s tie-bar-less injection moulding machines. The press release is available here.
In the award category, "Efficient use of the mould area", Hengst, based in Münster, Germany, won the award in connection with oil filter module bases it moulds from polyamide reinforced with glass fibre for various Audi and Volkswagen four-cylinder diesel engines. Selecting tie-bar-less technology meant Hengst can make the bases on an Engel victory 3550/450 tech machine with a clamping force of 4,500 kN, instead of a tiebar machine that would need to have a clamping force of at least 8,000 kN.
The second winner was Gardena Manufacturing (past of Husqvarna Group), which makes 20 million garden hose connectors per year, in the southern German municipality of Gerstetten. Since January this year, an Engel victory 740H/310W/400 WP combi has been used for a new two-component process. Winning in the "Innovative process integration" category, Engel said “only the tie-bar-less clamping unit makes it possible to combine maximum precision with very short cycle times” in the process.
Winner of the third and final category, "Economical automation concept", was Schneegans Freudenberg Silicon. The company uses projectile injection technology to produce automotive parts in Losenstein, Austria. In the automated production cell, based around a tie-bar-less Engel victory 400 tech machine, four integrated multi-axis robots share the tasks of inserting the projectiles, removing the moulded parts from the mould, detaching the overflow cavities, printing on the front of the funnels, fitting O-rings, assembling oil sleeves and dipsticks, leak testing and packaging the finished modules.
In addition to the winners, ENGEL has announced the names of the other applications that made the shortlists for each category. Gustav Hensel (Lennestadt, Germany) and UAMT (Oradea, Romania) completed the "Efficient use of the mould area" list with the manufacture of covers for cable junction boxes and the production of handbrake handles, respectively. In the "Innovative process integration" category, the remaining shortlist places were taken by Valeo Autoklimatizace (Rakovnik, Czech Republic), which submitted its fabrication of ventilation flaps for cars, and Tente-Rollen (Wermelskirchen, Germany), whose application was the manufacture of double castors for hospital equipment. In the "Economical automation concept" category, Mora (Mora, Sweden) and Weidplas (Rapperswil, Switzerland) were the best-placed candidates behind the winner with the fabrication of outdoor knives and the production of air ducts and bonnet scoops, respectively.
