• Injection Molds
There are several different reasons why you might blast a metal surface. Surface preparation or paint removal, deburring or maybe you need to clean off residue that’s built up on a metal mold.
Coulson Ice Blast is a faster and cheaper method of removing rubber residue from tire molds. Ice is gentle enough that it won’t wear away the mold, but aggressive enough to clean the rubber residue off it. Compared to competing technologies, ice can be made practically for free, using any standard ice cube maker. Ice blasting is a great way of removing burrs during the manufacturing process. Ice will deform on impact and squeeze its way through small holes, tight slots and channels, knocking off burrs as it goes. As a result, it can be used to clean off tiny burs from small or complex parts. Ice blasting will not damage the parent metal. Other deburring processes usually round off corners and edges. This can be a problem when a high tolerance is needed on parts. Ice blasting just removes burrs, without rounding the edge. At the same time, ice blasting removes greases and cutting fluids left over from machining processes, performing two operations at once.
Because of its dust suppression qualities and minimal residual moisture, ice blasting makes containment easy. It is an ideal technology for removing hazardous substances, such as lead paint. The spray of water captures blasted off particulates and drags them downwards, resulting in lower levels of airborne contaminants. If a tarp is placed beneath the blast area, the lead paint will collect on top of it in a neat slushy pile. Containment and disposal are as easily as folding up the tarp after blasting. For this reason, ice blasting is used to clean lead paint off large bridges.
In these, and other Metal applications, Coulson Ice Blast is Redefining Clean.
