Investment in precision

Sternfenster has invested in aluminium crimping technology, which it said brings new levels of precision to its product lines.

The new four-head Ever Theta frame crimping machine from FOM uses profile scanning technolog to bring exceptional accuracy to manufacture.

This includes flagging out-of-tolerance profiles of as little as 0.4mm in length or 0.9mm on the diagonal, bringing a very high degree of accuracy to 45° mitre and 90° joints.

Managing director of Sternfenster Mike Parczuk said the new platform supported Sternfenster in not only increasing quality of manufacture of aluminium products but delivering new levels of consistency.

“It allows us to deliver a step change in product quality,” he said. “The precision that the new crimper brings to manufacture is incredible. It picks up out-of-tolerance profiles in a way that you simply cannot do manually – however good the individual operative.

“More importantly, it does it over and over again, bringing a far higher degree of consistency to manufacture compared to manual processes. That means we can guarantee product quality from the first to the two-hundredth frame. It’s about repeatability.”

The latest addition to Sternfenster’s £3.6 million aluminium manufacturing facility, the new Eva Theta Crimper, comes hot on the heels of the fabricator’s purchase of a new Schirmer ALU BAZ Composite Orbit-C machining and cutting centre.

This in addition to its FOM LMT cutting and machining centre, and its own powder coating line.

Therefore, Sternfenster can offer competitive lead times across its range of Smarts Visoline, Visofold and Alitherm 300 product offers, the company said.

The Ever Theta also cuts full-cycle times to as little as two minutes and 31 seconds, which is roughly half the time it takes using a traditional single head crimper.
