Sandblasting Parts and Accessories
Sandblasting removes old layers of paint from metal parts, making reapplication easier. we offer an assortment of top-grade sandblasting parts and accessories suitable for blast cabinets, pressure pot sandblasters and guns.
Mineral abrasives include silica, which can cause debilitating lung disease silicosis. Other alternatives for mineral abrasives are soda, dry ice, plastic media or crushed walnut shells or corn cob grit.
Plastic Grit
Plastic grit is an organic abrasive that is designed to clean and deburr without changing or damaging the surfaces it removes, without producing dust, chemicals or toxic by-products, meeting MIL-P-85891 specifications for aeronautic applications. Guyson provides several varieties of Plasti-Grit to meet blasting needs in different automotive finishes or substrates.
Blast cleaning is used to rid surfaces of contaminants and prepare them for thermal spray coatings, but can also be employed in metallurgy to roughen up surfaces for welding or shot peening, leaving an ideal surface profile for future coatings to adhere to the object, as well as prepare material for refurbishing such as painting or refinishing.
Sandblasting works by using pressurized air to propel media ranging from walnut shells and glass beads to steel shot, which are stored in a blast pot with adjustable valves to control size and abrasiveness of media, down through its length before exiting through its nozzle and hitting whatever surface needs to be cleaned, stripping off whatever residue lies on its surface while creating small divots in its surface that allow future coatings to adhere more readily.
Blast cleaning often involves metal surfaces like ship hulls and bridges that must be regularly painted to protect them from rust and corrosion, including ship hulls and bridges, which have to be painted regularly to keep rust at bay. As part of the painting process, heavy metals and other hazardous substances can accumulate within their paint layers which then release these harmful substances into the environment through blast cleaning action.
Steel Shot and Grit
Steel shot and grit are popular blasting media for metal surface cleaning, as they're highly effective abrasives for removing paint, corrosion and other contaminants from metal surfaces. Because of their hard surface material, steel abrasives can even be used for shot peening to strengthen gears and springs by repeated impacts against them.
Steel shot and grit are among the safest forms of blasting media to use, as they don't shatter into harmful dust particles like other forms of media do. Workers should however wear the appropriate safety equipment such as protective masks and eyewear when working with this type of media to lower risks of health problems and improve productivity. It is also advised to follow proper ventilation and dust control measures during blasting sessions with steel shot or grit for optimal results.
Steel shot and grit are available in an assortment of sizes. Made from high-grade stainless steel molten into round shapes through an atomization process, both types of media can be used for metal blasting or other industrial purposes such as cleaning out tight spaces with debris that larger-sized shots cannot access.
Glass Beads
Glass bead blasting is the process of using spherical-shaped media to achieve semi-polished and peened finishes on metal parts, using gentler methods than sandblasting for maximum surface preservation and less surface damage. Glass bead blasting works particularly well on softer metals like aluminum and cast iron and creates soft surfaces with enhanced mechanical strength for improved mechanical strength of parts.
Glass beads are constructed of recycled and inert material, providing a cost-effective alternative to sand. Reusable several times before losing effectiveness, they reduce both costs and environmental impact while leaving behind a uniform satin finish or rougher texture depending on their size - finer beads will create a satin surface while coarser beads produce rougher surfaces.
Size matters when it comes to bead blast finishes; be sure to include in your order notes when requesting a quote the desired size abrasive grit size you desire.
Remember to invest in a high-quality bead blasting cabinet to protect both workers and final product quality. Such an enclosure will enable temperature regulation and media dispensation during blasting processes; furthermore, a quality cabinet should feature a large view window so you can observe work areas inside.
Steel Nozzles
As part of sandblasting parts like steel shot and grit, it is vital to carefully consider your nozzle materials. Nozzles come in different materials like steel, aluminum and carbide with aluminum being lighter and cheaper while carbide being longer-lived and capable of handling higher blast pressures.
No matter if you are cleaning the weld seams on a steel tank, blasting rust off an old railing or carving stone - your nozzle will determine how efficiently and effectively you can clean the surface. Furthermore, its shape impacts its size of blast pattern - generally straight bore creates tight blast patterns which is best for spot blasting or blast cabinet work whereas venturi nozzles create wider blast patterns and increase abrasive velocity for increased productivity.
Some supply companies offer composite and tungsten carbide tips for their sandblasting nozzles, which have proven their longevity over time and can be used in multiple tasks in addition to boron carbide tips which come second in durability.
An alternative solution is purchasing a wet abrasive blasting system, which tends to be smaller, portable and much quieter than dry sandblasting systems. They work by pulling in the media directly through their gun siphon hopper instead of pushing it through a hose - perfect for occasional use, general cleaning tasks or light production needs.
