Die Cutting is a highly efficient means to produce large volumes of uniquely shaped parts while creating a low volume of wasted materials. There are several different ways to produce die cut parts with one of the more common being Rotary Die Cutting. A Rotary Die Cutter typically incorporates the material passing between a roller die cutter and a heavy roller anvil to cut the specific shape  then passes the material down a conveyor or feed line while retrieving the waste material in another collection device.

I recently worked with a customer who was starting to see a large volume of scrap in their vinyl and rubber parts die cutting process as the die cut parts themselves were getting stuck onto the rolling die cutter and weren’t getting grabbed by the conveyor rollers. To try and get the parts to eject from the cutter they installed a few 1/4″ open copper tube air lines running across the roller but were concerned with amount of air they were wasting and the high pitch noise levels of close to 100 dBA. They were also seeing some damage to the parts they were able to get loosened from the die as some of the parts would make contact with the pipe, causing a “blemish” on the part, ultimately failing inspection.

I recommend the customer use our Model # 1100-PEEK Super Air Nozzle. The Model # 1100 consumes only 14 SCFM of compressed air (at 80 PSIG), much less than a 1/4″ open pipe, tested at close to 140 SCFM @ 80 PSIG. This nozzle produces a low sound level of only 74 dBA falling well within the allowable noise exposure levels set forth by OSHA. In addition, the PEEK plastic construction provides a non-marring solution in the event one of the parts did make contact with the nozzle.

EXAIR offers a large selection of engineered air nozzles with varying airflow patterns, force, sound levels and materials of construction to meet a wide variety of application requirements. With help selecting the best solution or to discuss your particular application, please give us a call.
