Description
Plastic Cone Tumbling and Filler Media - Rock and Soft Metal Polishing - 5/8" x 3/4" Size
Winona Van Normans cone-shaped plastic tumbling media produces a smooth finish with little shine. It is excellent for preparing parts for anodizing, smoothing injection and compression-molding parts, smoothing 3D printed parts, deburring and smoothing soft metals (brass, zinc, and aluminum), and large rock tumbling. The cone shape works particularly well with parts that have holes and avoids rolling the burr into the hole.
30% lighter than ceramic media. It does not discolor metal and does not peen over burrs.
Made of 50% silica and 50% resin.
Rock Tumbling Applications
Transporting grit
Plastic tumbling media picks up and holds grit, carrying it to and rubbing it against hard-to-reach surfaces. The small media size helps it smooth surfaces. It is ideal to maximize the points of contact your grit and your rocks.
Quieting your tumbler
Plastic tumbling media has more sound absorption than ceramic media and will quiet your rock tumbler by muffling the sound of rocks mixing.
Smooths injection molding parts
Smooths a wide range of injection-molded parts. Suitable for low- and high-volume production of simple and complicated shapes. Cone-shape plastic tumbling media is especially good for injection-molded parts with holes in order to avoid rolling the burr over into the hole.
Smooths 3D-printed parts
Additive manufacturing 3D-printed parts are made layer by layer, and our plastic tumbling cones are gentle enough to smooth the finish of hard to reach surfaces without damaging parts.
Smooths Compression molding parts
Compression molding uses pressure and heat to form raw material into a new shape. Our plastic tumbling cones gently smooth the finish on compression-molded parts.
