Learn how much power it takes to clean dirty molds.

Visitors to NPE2015 next week in Orlando, Fla., will be shown a simulation to indicate the superior cleaning power of magnetostrictive-type ultrasonic cleaning tanks for removing polymer residues from molds. FISA North America, Inc., Elk Grove Village, Ill., will display a cleaning tank with different ultrasonic generators on opposite sides. One is the piezoelectric type that is often used for cleaning plastic parts but does not have sufficient power for cleaning molds, according to FISA’s Philippe Vaudeleau. On the other side will be FISA’s magnetostrictive technology, with a massive, 45-lb transducer, capable of cleaning heavy mold components with heavy contamination, Vaudeleau says. This contrasts with a typical 1-lb piezoelectric transducer, more suited to high-precision cleaning and removal of tiny dirt particles from the surface of lenses and other small parts.

 

Besides being faster and more thorough for cleaning molds, Vadeleau notes that its magnetostrictive transducers can work at higher temperatures—up to 190-195 F, vs. 120 F for piezo-type transducers.

 

Vaudeleau says FISA has sold more than 200 ultrasonic cleaners to U.S. molders and moldmakers over the last 12-13 years.

    In tough economic times, facing hungry competition here and abroad, molders cannot afford to ignore preventable problems that slow cycles, cost machine downtime and mold maintenance, and waste material on reject parts.

  • Determining Maximum Mold Cycle Counts

    The first production meeting with my new employer went something like this: “We want you to establish a preventive maintenance program that is based on cycle counts for all our molds.” Before I could launch into an explanation of how best to determine maximum cycle counts, I was hit with this: “So, how many cycles do you think our molds can safely run before we need to clean them?”Leaving my crystal ball at home and unable to get my x-ray vision working, there was no way to answer that question with any accuracy.
