Polyurethane Mold Cleaning

Urethanes are an adhesive and will bond to aluminum or steel molds.  Over time, the molds used in the casting of urethane and polyurethane parts build up a residue and require cleaning.  Magnus Engineered Equipment (MEE) can provide a cleaning process wherein the molds are cleaned in less than 5 minutes and without any damage or distortion to the mold.  Dis-assembly of the mold is not required for cleaning.  Any size or weight mold can be cleaned with the MEE cleaning process.

In the past, producers of molded urethane parts would use an abrasive or grit blasting to clean the molds after casting.  This cleaning process caused the mold surface to become rougher which then made mold release and mold cleaning even more difficult.  These cleaning processes often required dis-assembly of the mold and many hours of effort to remove the surface contamination.  Using 20 kHz magnetostrictive transducer technology, MEE can provide a cleaning process which will clean the mold without dis-assembly, cause no harm to the mold, and will clean the mold in less than 5 minutes!

MEE manufactures and supplies the most powerful ultrasonic cleaning equipment for cleaning applications.  Unlike the commonly used piezoelectric transducers which operate at 40 kHz, MEE supplied magnetostrictive transducers which operate at 20 kHz and deliver ~25 times more cleaning power than piezoelectric transducers.  Higher power equates to more thorough cleaning, faster cleaning speeds, or both.  Figure 1 shows the cleaning power comparison between MEE’s magnetostrictive transducers and piezoelectric transducers.

Here are some photos of molds with polyurethane contaminant which were cleaned with the MEE process. 

Before Cleaning After Cleaning

Keeping Your Cleaning Equipment Up-To-Date

Magnus Engineered Equipment strives to ensure customer’s expectations are met throughout the life of their Magnus equipment.  MEE stays engaged with customers throughout the machine life to ensure proper operation and performance.  It’s not unusual for customer’s to be operating 30+ year old cleaning equipment, and in such cases, MEE not only provides replacement parts but can also provide updated safety and electrical equipment.  After some years of operation, one customer encountered difficulties with pneumatic control panels.  The originally supplied panels utilized plastic air lines, however these air lines deteriorated due to frequent exposure to incompatible cleaning chemistries.  MEE stepped in and remedied the customer’s problem by supplying pneumatic control panels constructed with stainless steel air lines.  Like other wetted surfaces in the cleaning system, these control panels can now withstand the harsh environment and allow the cleaning line to function without issue.

MEE builds their equipment to be code compliant, but aged cleaning equipment can also be refurbished to encompass the newest controls, safety equipment and be fully code compliant.  Tanks which previously had manually operated lids can be retro-fitted with pneumatically operated lids.  Surge suppression can be added to electrical cabinets to make them compliant with the latest electrical codes, and pneumatic systems which are antiquated can be updated to the newest technology.  Sometimes, older cleaning equipment is re-purposed in manufacturing environments and with small additions, the equipment can be optimized for the new application.  An example is when a cleaning tank is converted from a solvent chemistry to a water based chemistry.  The minor addition of filtration and/or oil coalescence can greatly improve the cleaning process and deliver other benefits such as longer and more reproducible bath performance.

If you have an older cleaning tank/system that could use some maintenance or updating, contact MEE to see what options are available.
