Abrasive Blasting 101
The concept behind a clamshell sandblasting cabinet seems incredibly simple. The traditional design for these cabinets is a hinged top that swings back to allow parts to be loaded by forklift or hoist. Based on appearances, it should be the perfect solution for loading and blasting large or large heavy parts. Unfortunately, there are several concerns when it comes to clamshell sandblasting cabinets.
ProTip: Processing a large part inside a slow, lightweight clamshell cabinet is a mismatch of gun cfm used and the size of the cabinet. It’s similar to painting a commercial building with a one-inch brush.
What is the solution to large part loading? An easily loaded mobile work cart with or without a turntable allowing attached side extension tracks or extension track table permitting part loading outside the cabinet. This design allows safety, and loading of every type of part with no damage to the blasting cabinet. For more information about this cabinet, contact our team of experts.
Clamshell sandblasting cabinets seem like a great solution, but buyers should beware of the machine’s drawbacks. If you have a large item than only requires a very small spot to be blasted, you may be fine using one of these cabinets. If you want to blast the entire surface of a large part and you need mechanical assistance loading and unloading the machine, you could most likely use something other than a clamshell blast cabinet. You might even be surprised to find solutions that are less expensive and much less messy.
