Media-Ceramic and Polyester Resin

Ceramic and polyester resin (plastic) Medias provide a superior finish to a wide variety of parts when added to a mass finishing machine. While ceramic media can be used on all metal types, polyester resin media is perfect for softer metals such as aluminum, brass, or copper where impingement may cause a problem.

Chosen by SHAPE, SIZE, and, COMPOSITION (CUT), media determination is based on the dimensions of the part as well as the required APPLICATION and desired finish.

Angle Cut Triangles provide for a uniform and effective finish. They offer maximum surface contact on flat surfaces and allow for the angled sides to penetrate into comers.
Angle Cut Triangles-45° Angle Cut Triangles-45° 5/8" x 5/8"
7/8" x 7/8"
45° Triangles provide a sharper angle for even better penetration in remote areas. The elongated shape gives better flowing action over the parts during processing

3/16" x 3/16"
1/4" x 1/4"
2" x 2"
2" x 1"
Straight Cut Triangles offer maximum surface contact on flat surfaces. The straight sided shape gives a blocky action that helps maximize cutting action.

1 1/8" x 3/8"
1 3/8" x 7/16"
1 3/8" x 1/2"
1 7/8" x 5/8"
Angle Cut Stars or Tri-Stars have the basic capabilities of a triangle, along with sharp points for reaching into remote areas. Ideal for gear teeth, slots or sharp corners.
Angle Cut Cylinders-22° or 30° Angle Cut Cylinders-22° or 30° 1/8" x 11/32
3/16" x 11/32" or 3/8"

7/8" x 1 1/2" or 1 3/4"
1 1/8" x 1 3/4"
Angle Cut Cylinders are best for use on concave surfaces, rounded areas and holes. Can be used on a wide variety of parts.
Angle Cut Cylinders-45° Angle Cut Cylinders-45° 1/4" x 5/8"
5/16" x 5/8"
3/8" x 5/8"
1/2" x 5/8"
5/8" x 3/4"
The 45° Cylinder reaches recesses, holes and remote crevices with even greater penetration than the 22° angle cut cylinders.
Angle Cut Cylinder-60° Angle Cut Cylinder-60° 1/4" x 9/16"
5/16" x 9/16"
3/8" x 9/16"
The 60° Cylinder reaches recesses, holes and remote crevices with even greater penetration than the 22° or 45° angle cut cylinders.
Tri-Cyls or Cyl Cut Tri-Cyls or Cyl Cut 3/8" x 3/8"
5/8" x 5/8"
1 1/2" x 1 1/2"
Tri-Cyl or Cyl-Cut Media is a versatile shape suitable for use on a wide variety of surfaces. Made with a cylindrical surface that mates well with concave surfaces, plus two flat surfaces that perform well on convex surfaces. Tri-Cyls also combine the strong points of both triangles and cylinders to penetrate into corners, slots and angels.

Ceramic Spheres offer a smooth, rolling action which enables them to easily roll around and through parts to produce a cleaning and blending action. Provide good contact in rounded areas.
Angle Cut Ellipse-22° Angle Cut Ellipse-22° 5/16" x 3/16" x 1/2"

9/16" x 1/4" x 7/8"
3/4" x 3/8" x 1"
1" x 7/16" x 1"
The Angle Cut Ellipse media combines the finishing action of a flat shape with the flowing action of a cylinder. They are especially effective on concave surfaces and have anti-wedging characteristics that reduce or eliminate lodging.
Cones Cones 3/8" x 1/2"
1/2" x 5/8"
9/16" x 5/8"
11/16" x 3/4"
3/4" x 7/8"
1 1/4" x 1 1/4"
Due to its tapered shape, cone media extends media life and has anti-wedging characteristics that reduce or eliminate lodging. Good media for parts with holes.

Pyramid and Tetrahedron media offers great anti-wedging characteristics which help reduce or eliminate lodging. Good media for aluminum die cast where lodging is prevalent.

CERAMIC MEDIA COMPOSITION determines wear life of the media, cutting action, and, cosmetic appearance of the parts. Each media can be ordered in a specific composition based on desired finish.

NON-ABRASIVE or POLISHING - Extremely hard and long-wearing media recommended for brightening, burnishing and polishing. MILD CUT or LIGHT CUT- Versatile, general purpose, mildly abrasive. These products combine low media wear rate with reasonable metal removal rate. They produce a fine finish and can be used for and burnishing with proper compounding.
MEDIUM CUT or GENERAL PURPOSE - Formulated for a high performance cutting action for deburring and metal removal.
FAST CUT - Most aggressive cutting media for the removal of heavy burrs, flash or scale. Used for maximum metal removal in the minimal amount of time.
HIGH DENSITY - Extremely resistant to fracturing, ideal for high-energy applications. Very fast cut facilitated by heavier weight per cubic foot.

PLASTIC MEDIA is available in both High Density and Low Density compositions.

All media is pack in 50lb boxes
