Industrial vacuum specialist Ringler GmbH, located in Waldstetten, Germany, and part of the Kärcher Group, has announced that it has begun making a range of suction nozzles by selective laser sintering. The Additive Manufacturing process results in considerably faster production and enables better airflow properties inside the nozzle, the company stated.
Standard nozzles are often unable to completely remove shavings and dust from increasingly complex workpieces in processing machines. Part cleaning plays an important role in the industrial production process as only clean workpieces can be further processed without faults. Until now, custom-built nozzles entailed high design engineering and manufacturing costs due to the large number of individual components.
Typical construction practices involve many individual metal parts being welded into a single component. In the selective sintering laser process, nozzles are built in one piece and require no elaborate assembly design. As a result, suction nozzles can be produced in a quarter of the time.
In addition to improvements in speed and product design, airflow properties inside the nozzle have been refined to reduce loss of suction power. In addition, a blowout function can be integrated with a blast of air through an additional airway connected to a pressurised airline removing any adhering swarf and dust or ejecting it from recesses, after which it can easily be vacuumed up.
