A safer and more effective method for removing polymer buildup from production dies. Easily remove polymer buildup from the holes in the spinnerets or dies.
Manufacturers of polymer nonwoven products are increasing production rates with dry ice blasting. Regardless of the manufacturing method, spunbond, melt-blown, wet-laid, or needle-punch, cleaning is an integral part of maintaining and improving product quality and productivity.
Traditional cleaning methods of a melt-blown die can take many hours and multiple shifts. Cleaning with Cold Jet’s dry ice MicroParticles is measured in only minutes depending on the size of the die. This significantly reduces production downtime.
SPECIFIC USE CASES
Dry ice blasting effectively removes various polymers (PP, PET, TPU, PA, PE, PC, PS, etc.) from dies utilized to manufacture a variety of nonwoven products
The dry ice blasting process brings a variety of advantages over traditional cleaning methods.
The process is non-abrasive and extends the asset life of the die. With dry ice, there is no longer a need to manually drill out die holes or scrape off excess polymer. Dry ice blasting is a dry process and does not require water or ultrasonic tank cleaning and does not produce secondary waste. It is also environmentally sustainable and eliminates the use of chemicals.
We have reduced cleaning time by 98% with dry ice blasting. Die cleaning previously took 10-20 hours to clean polypropylene from a 600mm melt-blown die spinneret holes. By utilizing Cold Jet’s MicroParticle dry ice, we clean the mold in 12 to 20 minutes.
