The turbo advantage

Stuga Machinery has bought the Stürtz HSM 6-KV Turbo corner/transom welder to the UK. Here’s how it could increase your output by 163 frames per week.

Stuga Machinery is the exclusive supplier of Stürtz machines in the UK. The HSM 6-KV offers servo-driven, high-speed welding technology, whilst giving fabricators precise control, the flexibility to weld a full range of window frames, sashes and doors, plus a predicted 14% increase in productivity – or an additional 163 frames per week at 100% equipment effectiveness (OEE).

 

Turbo powered

Stürtz says that traditional pneumatic-controlled welders rely on air cylinders for linear movement, thus limiting control to speed and pressure. The HSM 6-KV replaces these pneumatic systems with servo-controlled axes, providing operators with complete control over each welding phase. By combining higher heater plate temperatures with gradual, pulsed fusion of the servo axis, the turbo corner/transom welder produces faster, consistent and durable welds.

The Turbo heats to 280°C and completes fusion in just 10-15 seconds – versus the conventional 240°C and 25-30 seconds of traditional pneumatic welders, with additional time savings during the pulsed fusion phase. This improved cycle reduces overall welding duration by 15-20 seconds, enhancing production rates. Based on an 8-hour working/5-day working week, Stürtz arrives at the 163 extra frames calculation. The firm claims this can be done without compromising joint strength at all.

 

What to expect

Stürtz also claims that the welder features a user-friendly operator interface that simplifies the loading and welding sequence. Operators start the sequence. The machine then moves to the loading position to allow easy placement of the top frame, transom sides, and bottom frame. Once loaded, the operator initiates the welding cycle. Once complete, the machine discharges the frame onto the corner cleaner line, ready for the next stage.

The welder offers a loading sequence designed for efficiency. Rear corner heads move closer to the operator during the loading phase, which means easier and more accessible frame loading.

 

Enhanced precision and control

Servo-driven rear fences on all corners and transoms provide provide control during fusion and welding phases. Unlike conventional pneumatic systems with basic ‘on-off’ limitations, the servo-driven system allows for gradual torque adjustments, resulting in consistent and durable welds.

 

Reduced transom drop

The transom head design has been slimmed down, allowing for a smaller transom drop (reduced from 350mm to 230mm). This feature enables the production of smaller frame sizes.

 

First sale and FIT showing

“We are very excited to have the first Stürtz HSM 6-KV turbo corner/transom welder already installed and proving its capability for a customer in the UK,” says Ed Williams, the managing director at Stuga Machinery. “We will be showcasing it at the FIT Show in April and can’t wait to see the reaction it will get.

“We are always striving to not only meet but exceed industry standards. This machine gives manufacturers a valuable tool for increasing output, optimising production workflows and ultimately, profitability.”
