ARE YOU BLASTING WITH THE PROPER MATERIAL FOR
FOR YOUR APPLICATION?
Let Precision Finishing, Inc., help you evaluate your application!
We not only sell the material we use it. For over 25 years we have operated a blast finishing contract shop which is a perfect platform to test and experiment with different finishing materials. Whether you are looking for a glass bead cosmetic finish, an anchor pattern, paint removal on a delicate substrate or shot peening we have the experience to assist in your media selection process.
Glass Bead
 |
FLEX-O-Lite Glass beads
are spheres of uniform size and
hardness formulated of chemically inert
soda-lime glass. The impact of the beads
removes foreign substances from the base
surface without contamination and
dimensional change. Applications range from
cleaning, cosmetic, deburring and light
peening. It is one of the most versatile blast
finishing materials available. |

Aluminum Oxide
 |
| Aluminum Oxide has a blocky shape with
multiple, sharp cutting edges that penetrate
work pieces, dig-out microchips and leave
exceptionally clean etched surfaces. It is
effective on metals, glass, ceramic, marble,
granite and other stone. It has a MOHS
hardness of 9 which makes it a very tough
and durable material. During blasting it
fractures and thereby does not create a dusty
atmosphere. It is an excellent material for
cleaning and providing a uniform surface
or anchor pattern. |

Zirconia Aluminum Oxide
 |
| This aluminum oxide, developed by
Norton/St. Gorbain, has 23% Zirconium
Oxide in it. The result is a more durable and
fracture resistant abrasive for use in
high pressure applications. It too has a blocky
shape, however it fractures by smaller sizes
compared to regular aluminum oxide. It's
durability is proven in it's exceptionally low
breakdown rate and reduced nozzle wear.
It works very well for pressure applications
such as stone engraving, general metal
cleaning and the investment casting industry. |

|
Silicon Carbide
 |
Silicon Carbide is a very hard material
which is generally used for difficult
cleaning applications and where
contamination of aluminum oxide is a
concern. |
|
|
|
Steel Grit and Steel Shot
 |
Steel Grit/Steel Shot is commonly used in airless
applications since it is softer than
aluminum oxide and doesn't fracture
as easily. It is also used in direct pressure
applications where a heavy profile is
needed. Steel shot is used for shot peening
of ferrous materials. |
|
|
|
Ceramic Beads
 |
| Ceramic beads are product of a fusion
process of oxides at a Very high temperature.
Ceramic beads do not contaminate treated
parts by embedment of particles. Their
exceptional properties of toughness, impact
resistance, hardness and elastic allow them to
maintain their initial shape without shattering
even after a long period of time. They can be
used for general cleaning, deburring and
peening. |

Plastic Abrasive
 |
| U.S. Technology Corp. pioneered dry plastic
media blasting by removing paint from
aircraft bodies. The MOHS hardness of the
materials range between 3.0-4.0 which gives
the ability to remove coatings without
affecting the substrate. Over the years they
have expanded the process to coating-
removal requirements in the electronics,
ships, vehicles, bridges and buildings. There
isn't a material available that quite
accomplishes what plastic media does. [ sizes ] |

Agricultural Abrasive
 |
Commonly known as corn cob grit, it has characteristics similar to plastic media however it's alot softer. The MOHS hardness of cob is 1.0. It can be effective
in cleaning fragile material but isn't
as effective at removing paint and coatings
as plastic media. It can also be used
for light deburring and it's cost is low
compared to plastic media. |
