Dry Ice Blasting in the Automobile Industry: The Ice Age Has Arrived

In the restoration business, sand, grit, and glassbead blasting are well-known processes for removing grease and dirt build-up, underbody sealant, and paint off components and panels. Damage to the surface structure, resulting in buckles and bulges, is an unpleasant side consequence of these approaches. It would be nice if there was a gentler but equally effective option.

Dry ice blasting, a new technique, might be one solution. Dry ice particles impact the damaged area at high speeds during the blasting. The solid pellets decompose into gaseous carbon dioxide upon contact, resulting in a mild explosion. The paint or dirt layer is lifted and becomes rapidly chilled, brittle, and readily removed as a result of the sudden rise in volume. After then, the portion reverts to its previous shape.

Thermo Blast, a Queensland-based firm, is an expert in this type of blasting. Individual restorers can use Thermo Blast’s blasting services, and the company will also sell BUSE blasting equipment to the automotive industry. The dry ice pellets, which are readily accessible from major gas providers, are combined with air within the blasting unit in this German-engineered and manufactured technology. You may remove underbody sealant without harming the underlying paint coat by changing the air pressure and pellet concentration. The blasting unit may be precisely tuned to match the age and composition of sealants.

When compared to manual removal, dry ice blasting might save you a lot of time. Another advantage is that no pieces must be removed. Axles, steering components, springs, shock absorbers, and brake lines are not damaged by its non-abrasive nature. Rubber, other sealing materials, and even glass are unharmed. As a result, sensitive body elements like as door panels and bonnets may be processed without the risk of pitting or warping. Chrome, aluminium, and fibreglass are all considered to be safe. Dry ice blasting may also be used to clean engine components, such as pistons and cylinder heads. There is no residue, unlike grit or glassbead blasting, that might cause an oil duct obstruction later.
