Abrasives & Media

TRIN MIXES

Trinco’s exclusive combination of glass bead and aluminum oxide delivers fast and efficient cutting action while maintaining close tolerance and a fine satin finish. With three grades to choose from, one will be the solution to your cleaning/finishing application.

TRIN-MIX # 4:

The finest of the Trin-Mixes, Trin­-Mix # 4 is ideal for removing light to medium contamination from tools, tooling, molds and dies. It is considered a general purpose media which can be used in a wide range of applications from texturing plastic injection molds to providing appealing finishes on exposed stainless steel and aluminum surfaces. Dimensional change of less than .001 inch can be expected.

TRIN-MIX # 2:

Somewhat more aggressive than Trin-Mix # 4, Trin-Mix # 2 promotes faster cleaning and a slightly rough finish. Ideal for heavier contamination where a dimensional change of minus .001 inch is acceptable.

RAD-MIX:

This is the most aggressive of the Trin­-Mixes. Although developed for the radiator rebuilding industry, it is ideal for removing tough contamination from surfaces with a minus .001 inch tolerance or better.

TRIN-BEADS (Glass Beady:

A very popular media used primarily for dimensionally sensitive applications where tolerance and finish are your main concern. It is used widely by automotive rebuilders, die and mold makers, the plating and aircraft-aerospace industries. Trin-Beads are perfect for removing medium to light contamination without causing dimensional change, over­stressing, imbedding or pitting. Mesh sizes range from extra coarse # 3 (20-30 mesh) to extra fine # 13 (170-325 mesh). Following are descriptions of typical applications:

COARSE – BT # 3 & 4:

Good for cleaning heavier contamination and peening for stress.

MEDIUM COARSE BT # 5, # 6, & # 7:

Good for engine rebuilding, mold texturing, and peening of softer metals.

MEDIUM – BT # 8, # 9, # 10:

Good for plating, anodizing preparation, and most general applications.

FINE – BT # 12 & # 13:

Good for cleaning light contamination and wherever a fine surface finish is desired.

TRIN-BLAST (Aluminum Oxide):

A highly aggressive abrasive ideal for applications where tough contamination is encountered and stock removal of .001 to .002 inches is acceptable. The resulting finish is ideal for painting, plating, coating or wherever a matte finish is desired. Grit sizes range from # 12 (Coarse) to # 240 (Fine).

SILICON CARBIDE:

This extremely aggressive abrasive is used in many of the same applications as aluminum oxide, where faster cleaning and/or deeper etching is required.

WALNUT SHELLS:

This soft aggregate is used in blasting processes for removal of foreign matter or coatings from surfaces without etching, scratching, or marring the cleaning area.

i.e. Cleaning delicate molds, armatures and/or electric motors prior to rewinding.

COB GRIT:

Known as soft grit blasting, this natural cellulose grit is derived from corn cobs; used for removing light foreign matter such as carbon, oil and dirt without affecting surface.

STEEL SHOT:

A solid round particle causing a peening action and producing a dimpled surface. Its heavy weight gives greater impact and hammering action for peening and cleaning heavy forgings and removing heat treat scale.

STEEL GRIT:

An angular media, and like thousands of tiny chisels and cutting tools, does a fast cleaning job. Produces an ideal surface for adherence of new coatings. Often shot and grit can be mixed to achieve different finishes.

PLASTIC:

This relatively new, dust-free media is a special formulation of plastic material that has high tensile, compressive and flexural strength, combined with comparatively low hardness. Used for deflashing plastic parts and cleaning molds, dies, electronic connections, and circuit boards. It can effectively deburr machined-iron castings and non-ferrous screw machine parts.
