The customer was having difficulty cleaning their molds with their standard heat and wipe method. The buildup generated by the mold release and polyurethane would not melt.
Improve the effectiveness of a heat and wipe mold cleaning system.
Once it was determined how hot they could heat the tools, we developed a hard wax base coat that would be applied to a clean tool.
This material functions as a mold sealer and base coat.
The wax blend had a high enough melt point, so it provided a hard film even with the exothermic temperature generated by the foam reaction but would become liquid when the mold heaters were turned up to the cleaning temperatures.
Using this process allowed the customer to effectively use the heat and wipe method and eliminated the need for chemical cleaners or ice blasting.
