Examples of Typical Glass Media Blasting Applications

Glass media blasting is a flexible process that is commonly used in a wide range of manufacturing processes. Smaller glass bead abrasive material is well-suited for lighter processes involving fine detail work. Medium-size glass beads make the best choice when working with metal materials such as aluminum and stainless steel and are known for their ability to hide defects on the substrate surface. Large glass beads work well for cleaning and deburring of rough surfaces found on many metal castings and various automotive parts.

Another important benefit of using glass beads for sandblasting is that the process generates a relatively small amount of dust. This is because glass beads can be blasted at a lower PSI than many other types of media. Reduced dust levels enhance operators’ visibility during the blasting process, allowing them to work more effectively. Less dirt and dust also saves time and reduces the costs associated with keeping the work area clean, which can have a positive impact on the company’s bottom line.
