Raufoss Technology in Raufoss, Norway, manufactures link arms and other aluminum parts for the automotive industry. By having long-standing partner AP&T upgrade one of the company’s existing forging lines with a new, specially designed 2500 ton hydraulic press, not only have cycle times been reduced but the company can also manufacture larger parts than before. 

Some projects are simply more challenging than others, and in this case the challenge was twofold. The first challenge was the design and construction of the press. To be integrated into the existing line, the new press with its higher tonnage, had to be adapted to the physical limitations of the factory premises. Among these were the ceiling height and the size of the foundation, which required many special solutions.

Secondly, there was the matter of time. Raufoss Technology wanted the upgrade completed as quickly as possible. AP&T’s answer was a tight schedule in which everything needed to go according to plan to reach the finish line.

“We had a tight slot for installation, but AP&T did a good job, and everything was finished on time,” says Ole Ronny Heksum, project manager at Raufoss Technology.

One year after the order was signed, almost to the day, the machines and control system were finally in place.

Explains Mikael Karlsson, product manager of presses at AP&T: “We had to lift the press through the roof of the factory using a crane. Everything went smoothly and the entire installation, including the integration and commissioning, was completed in just 12 days.”

Adds Heksum: “After a period of adjustment, we can now manufacture parts with significantly higher pressing forces than previously, and at a higher production rate.”
