New laser tech shaves costs
DOMUSA Teknik makes and sells heating, ventilation, and air-conditioning (HVAC) products with a particular focus on solar systems for domestic water heaters, cast-iron and steel gas/oil boilers, biomass boilers, hot-water heat exchangers, electrical boilers, and diesel burners.
Until 2014, the company used a punching process to cut steel sheets for boiler manufacturing. This process involves cutting the cold sheets with a mechanical device formed by two tools: a punch and a die. The punch is compressed into the steel under force. The cut piece is separated from the sheet leaving off-cuts which cannot be used, resulting in signifcant waste raw material.
To improve efficiency, DOMUSA purchased two new fibre laser-cutting machines to replace the steel-punch system. Laser cutting directs a high-power beam at the material, and can be programmed for precision-cutting jobs which maximise raw material use and minimise losses, reducing waste generation.
