Glass bead blasting is an effective way to strip, clean, or finish metal and plastic surfaces without damaging or changing shape of substrate. Glass bead blasting is often used to remove corrosion, paint, and other surface contaminants from a variety of materials, including steel, aluminum, brass, and plastic. It is also used to polish and clean parts such as hydraulic cylinders, bolt heads, and large assemblies.
Glass bead blasting is a type of abrasive blasting that uses small glass beads as media. The main advantage of using glass beads is that they are not as aggressive as other blasting media, while still providing an effective and efficient method of stripping, cleaning, and finishing surfaces. The size of beads is an important factor in determining results.
Glass bead blasting sizes are typically measured in mesh sizes, ranging from 30 to 500. Mesh size is number of holes per linear inch when a screen is placed over abrasive media. The higher mesh size, smaller size of abrasive particles. A 30-mesh glass bead will be larger than a 500-mesh glass bead.
The size of glass bead used depends on type of surface being blasted, desired outcome, and thickness of material being blasted. Generally, larger bead size, more aggressive blast. For thinner materials, such as sheet metal, a finer bead size should be used. Thicker materials, such as cast iron, will require a larger bead size to achieve desired results.
When selecting appropriate glass bead size for a project, it is important to consider thickness of material, desired finish, and type of surface being blasted. The size of bead must be chosen based on size of particles needed to achieve desired results.
Glass bead blasting sizes can range from 30 to 500 mesh, depending on type of surface being blasted and desired outcome. By using right size of glass bead, surfaces can be effectively cleaned, stripped, and polished without damaging underlying material.
