Abrasive Blasting is used for cleaning and preparation. Blasting is the quick and easy way to remove foreign matter from metal, rubber, or plastic. Blasting is an excellent method for removing rust, heat-treat scale, corrosions, paint, flash-burn and dirt.
Blasting also prepares parts for assembly, plating, anodizing, painting, and/or coating. It’s efficient, economical and fast.
Blasting Techniques, Inc. has the capability to blast with Aluminum Oxide, Silicon Carbide, plastic, Nicklepowder, course slags, blackbeauty, starblast, steel shot, and of course glass. All size grits are available and certifiable.
FAA approved SPOP 8, 9, 10, and 218.
Tumble to Deburr
Several methods of tumbling are available, conducive to your parts:
- Barrel tumbling for large volumes
- Tub tumbling for larger heavy parts
- Sweaco tumbling for hard-to-reach burrs
- Orbital Barrel Finishing (Harperizing) to achieve smooth polished finishes
The purpose of deburring is to remove burrs or flash from machined or stamped parts. Our variety of medias allows us to attain your desired finish on almost any surface. We are equipped with a Comparator and Surface Tester to achieve your appropriate surface finish and edge break. FAA approved SPOP 180, 182, 184, 186, 188.
Orbital Centrifugal Barrel Finishing is a form of tumbling. Like tumbling, it uses media and water to deburr and finish parts. Unlike tumbling, the high forces generated by centrifugal finishing is actually two barrels attached to a turret, which spins in a counterclockwise direction. The action inside the barrel is rather that of media and parts pressing and sliding together. It enables the surface to be uniformly refined and can achieve high compressive stresses on the surface. P&W approved for PWA-107.
Shot peening is a process in which Blasting Techniques, Inc. covers the engineering requirements for peening surfaces by impingement of metallic shot to induce residual stress in the surface layers of parts, thereby increasing fatigue strength and resistance to stress-corrosion cracking. We adhere to AMS-2430 specifications and certify all completed work. All shot peening is in accordance with FAA approved SPOP 501, GE70-47-01, and P11TF8.
Glass Bead Peening
Glass bead peening is an approved method of propelling glass shot onto a material substrate in order to convert the shot’s kinetic energy into residual compressive stresses at the substance surface. Glass bead peening usually requires a lower intensity than shot peening. Blasting Techniques, Inc. has a P&W qualification for this procedure in accordance with AMS-2430, SPOP 500, GE70-47-01, and P11TF4.
Nicro-Blasting base metals prior to brazing improves the wetability of the surface for brazing filler metal (BFM). The grit “works” the surface, essentially peening it, which helps the BFM wet the surface better than the original untreated surface wetability: one of it’s main advantages is that it covers, and thus, prevents oxidization of metallic elements such as alumiand titanium in the base metal.
Vapor Blasting is known as Liquid/Vapor Honing or Wet Blasting. It is a process using water as a carrier of the media or grit to produce a soft slurry action rather than an aggressive dry action. Used in cleaning operations, it’s a finishing process for final inspection. This process does not change the dimensions of the part, but rather disguises scratches and eliminates minimum surface imperfections. FAA SPOP-9, 16, and 219: GE 70-21-05, P11TF4, and Rolls Royce Overhaul Process-104.
Automate and Manual
Glass Bead Cleaning is done with ground glass grit. All glass is Mil-G-9954 for certifications needed. All sizes of glass available. The purpose of glass bead cleaning is to provide a lustrous matte finish and improve the appearance and merchandise value of the part. Glass bead finishes add to the reliability of parts. FAA approved SPOP 16 for wet Glass Bead Cleaning and SPOP 500.
