Mutual Trust: Trelleborg supplies seals for the Arburg machines it uses in its own facilities

A high-performance machine such as the hybrid all-rounders from the Hidrive series operating in the packaging industry might well complete 7.3 million production cycles a year. Needing to demonstrate the highest possible performance under these conditions, one of these high-tech machines might contain as many as 20 Trelleborg seals and guide strips.
“We are always on the lookout for seals with as little friction as possible, that can be installed under any circumstances all over the world,” Krötz says. Hence the decision to switch hydraulic oils, from T46 to T29, after it became clear that micro scratches might appear on the piston rod if zinc-free hydraulic oils were used.
Joint testing in production
Tests are currently being carried out with the new high performance Turcon® M12 sealing material. To do this, Arburg machines that are in production at the Trelleborg Sealing Solutions facility at Stein am Rhein, Switzerland, are equipped with seals in the new material.
“In this way we carry out our testing together, under real production conditions,” explains Theodor Mack, a sales representative at Trelleborg Sealing Solutions. At Trelleborg’s Liquid Silicone Rubber (LSR) competence center in Stein am Rhein, Arburg’s green-and-yellow injection molding machines dominate the central production hall. Wherever you look, the characteristic shudder of the hydraulic hoses and movement of the handling units indicate that production is under way.
Full confidence in automated processes
“Our production is fully automated, and we have full confidence in the high efficiency of the Arburg machines,” says Jakob Bleiker, Technical Director of the Stein am Rhein facility.
Seals made by Trelleborg are also component parts for Arburg’s new freeformer, which heralded a new era in plastics processing when it was presented at the K 2013 trade fair, the international trade fair for plastics and rubber. It is likely that it won’t be long before the first of this newest generation of machines takes pride of place in a Trelleborg facility.
Arburg GmbH, based in Germany’s Black Forest, is a leading producer of injection molding machines for plastic processing. Trelleborg Sealing Solutions has high confidence in Arburg’s injection molding machines, with more than a hundred Arburg machines installed in 24 production facilities worldwide. Sealing systems that contain Trelleborg’s own seals contribute to long machine life.
Meeting high standards
“The people at Trelleborg have always been committed to providing us with sealing solutions that meet the high standards demanded by our machines,” says Martin Krötz, head of Arburg’s testing department. All new seals undergo thorough testing by the manufacturer before they are built into the injection molding machines.
Arburg GmbH
The German machine builder Arburg is a global leader in the production of injection molding machines with locking forces of between 125 and 5,000 kilo newtons for plastic processing. Other product lines include robot systems, turnkey solutions tailored to the needs of both individuals and industries, and other peripheral solutions. Arburg has branches in 32 locations in 24 countries and business partners in more than 50 countries. Production is carried out exclusively at the German headquarters in Loßburg.
Arburg Injection Molding Machines in Situ
The revolutionary Freeformer plastic injection machine
Arburg’s world premiere of the freeformer moves an unprecedented success story in the field of injection molding machines into a new, revolutionary process of additive manufacturing. The unique freeformer produces fully functional plastic parts using a new additive manufacturing technique – ARBURG Plastic Freeforming (AKF) – from 3D CAD files, standard granulates and without a mold. It therefore offers boundless freedom for the efficient production of individual parts and small-volume batches. Theodor Mack is excited “that our seals are involved in a worldwide sensation as it hits the market.” Trelleborg’s Turcon® Roto Glyd Ring® and Turcon® Roto Glyd Ring® D120 are used as internal seals while a Turcon® Roto Glyd Ring® seals externally.
