Dry ice is solid carbon dioxide, which is made by liquefying carbon dioxide into colorless liquid under the pressure of 6250.5498 kPa, and then rapidly solidifying under low pressure. Now dry ice has been widely used in many fields.

The history of dry ice can be traced back to 1823 Faraday and Derby in England. They liquefied carbon dioxide for the first time, and then Chirolet of Germany successfully produced solid carbon dioxide at 1834. But it was only used for research at that time and was not widely used.

applied range

Tire mold, rubber mold, polyurethane mold, polyethylene mold, PET mold, foaming mold, injection mold, alloy die-casting mold, hot core box for casting and cold core box can remove residual resin, invalid release layer, carbonizing film agent and oil stain, and can open air holes. After cleaning, the mold is as bright as new.

Dry ice cleaning does not need to cool and disassemble the mold, which avoids the corrosion and damage of the mold caused by chemical cleaning, the mechanical damage and scratch of the mold caused by mechanical cleaning, and the decline of mold accuracy caused by repeated loading and unloading. Crucially, the two most time-consuming steps of removing the mold and waiting for the mold to cool can be omitted, and the downtime can be reduced by about 80%-95%.
