In a pressure blast machine, the abrasive media is contained in a pressure vessel under pressure (at 40 to 100 psi) for use in the process. Examples of this abrasive media include steel shot or grit. Once the valve is open to start blasting, the media moves from the pressure pot through the grit valve and then through the hose to start blasting under pressure using the gun or nozzle. The media has two-to-three-times times the velocity on impact and would be close to three-times faster with stripping applications. Normal blasting pressure ranges from 35 to 45 psi.
The pressure blaster is also helpful when you need to complete the blasting process quickly. It moves three times faster than a comparable suction-based blaster cabinet.
A pressure blast cabinet is an ideal tool for removing contaminants, powder coating or heavy-duty layers of paint. The unique combination of air and abrasive media cuts, etches, abrades, cleans or otherwise changes the condition of the surface of your target piece. The process is a high-quality method of surface preparation.
The pressure blasting process offers several benefits:
- Control: Pressure blasting with an abrasive is ideal for preparing a surface. This process is the most thorough approach to cleaning metal. It creates an etched surface perfect for an excellent finish.
- Irregularities: The blasting process also gives the user access to clean the hard-to-reach spots of irregularly shaped parts.
- Applications: Beyond metal applications, a pressure blaster can etch glass, carve designs in wood or stone, harden manufactured parts and much more.
The pressure blast cabinet is a go-to solution when you need a heavy-duty tool that can move quickly and handle large quantities. That’s why the Advanced Deburring & Finishing team recommends these machines when you need to remove layers or want to smooth a rough surface at a rapid pace.
