Abrasive blasting is a process that is used to finish, clean or prepare metals and plastics using a variety of media in blasting machines. The blasting process works by shooting high-speed streams of abrasive blasting media at a surface to remove debris such as rust or other types of residual contaminants and scale. This abrasive blasting process is also important in the cleaning and roughening of part surfaces prior to coating.
The increased surface adhesion of a suitably blasted part results in a stronger bond between the coating and the parts surface. Abrasive blasting of medical implants increases the implant surface area, which in turn increases the percentage of bone attachment for medical and dental implants. Industries that utilize abrasive blasting include medical, aerospace, automotive, electronics, military and OEM manufacturers.
Abrasive Blasting Media
Abrasive blasting media is determined based on the application and comes in a range of sizes and types. Smaller blasting media typically creates a smoother finish, where larger media produces a rough finish. Shot blasting media is often recycled though the machinery and can be reused, making abrasive blasting a cost-effective process.
Some of the most common types of abrasive blasting media include glass beads, ceramic and aluminum oxide. Glass beads result in a soft, bright finish and are excellent for blasting and light deburring applications. Aluminum oxide is very abrasive and is used for blasting some of the hardest metals and surfaces. Other types of metallic, synthetic, and mineral blasting media are available depending on customer needs.
Abrasive Blasting Applications
Abrasive blasting is accomplished using different types of blasting machines set up to meet requirements for many different applications. Abrasive blasting is used by various industries and is ideal for the following applications:
- Removing glare when under surgical lighting for medical and dental instruments
- Improving adhesion for medical devices
- Increasing implant surface area, which increases the percentage of bone attachment for medical and dental implants.
- Descaling (removal of heat treat scale)
- Texturing for paint adhesion
- Texturing for mechanical function
- Producing a uniform cosmetic finish
