LOSSBURG, GERMANY — Production efficiency was the focus of this year's Technology Days event, organized in March by injection molding machinery producer Arburg GmbH + Co. KG in Lossburg.
Arburg defines production efficiency as an overarching “meta theme” determined by eight key elements; injection molding machine technology, mold technology, ancillary equipment (peripherals), equipment configuration, process integration, process control, production planning and product design.
The company's four-day open house in March attracted more than 5,200 visitors, 43 percent of which were from abroad, with 200 from Switzerland, about 160 each from France, Poland and Czech Republic and 140 from the U.S.
Some 2,700 visitors attended presentations by Arburg (on production planning), University of Leoben in Austria (on injection molds), BASF SE (on its easy-flow Ultramid B High Speed grade of nylon, and FPT Robotik GmbH + Co. KG (on inline printing).
A 60-metric-ton Arburg Allrounder 370E 600-170 electric-drive injection molding machine, which was equipped with a Kuka 6-axis articulated “industry” robot integrated with Arburg's Selogica control system, were key elements of the production cell, as was the integrated inline printing system.
A new servo-electric driven twin-screw “Injester” was shown for more effective feeding of high-viscosity and pastelike compounds, such as moist polyester bulk molding compounds and solid silicone. Another benefit is simpler and faster cleaning, the company said. A classic design BMC ashtray was molded on an Allrounder Alldrive 470A 1000-400 with an Injester feeding unit.
Optical part molding was covered by production of Fresnel lenses in a Momentive LSR material, as well as injection-compression molding of thick polycarbonate lenses. A medical application shown was a syringe housing molded in a 48-cavity Tanner hot runner mold in LyondellBasell's Purell HM671T grade of PP, achieving 13s cycle time for the 30-ml parts.
