Foundry & forging

Faster, better cleaning without dismantling

Reduces cleaning time by up to 70%

Standard cleaning operations in the foundry & forging industries involves cooling down and disassembly. Next step would be manual cleaning or bead blasting and reassembly. This is causing substantial downtime when cleaning core boxes / vents, permanent aluminum moulds, semi-solid castings and die casting production equipment.

PolarTech dry ice cleaning technology provides significant improvement in cleaning time and at the same time minimizing damage to equipment thereby reducing scrap products. By implementing PolarTech systems you can achieve up to 50 – 60 % reduction in cleaning time and at the same time increase your cycles between preventive maintenance.

Dry ice blasting is a non-abrasive, non-conductive cleaning method to be used in-situ and even touch-up cleaning are safe and easy.

ROI as little as 3 months has been achieved by using dry ice blasting and at the same time eliminating use of chemicals and sand/bead blasting. This meant exposure to workers of hazardous material/operations was minimized or even eliminated completely.

Cleaning technology of the future

Cleaning with dry ice has been used for several years. More commonly used are dry ice in pellet form or blocks using a shaving technology. Both technologies are subject to high investment costs and high running costs. These factors have so far been the obstacles for establishing themselves as a general cleaning process in the industries.

PolarTech´s patented technology is the solution to the problems above.
