Are you looking for a more efficient and eco-friendly way to achieve optimal results in your finishing process? Look no further than plastic media. This innovative abrasive material offers numerous benefits that can elevate your finishing game and transform your surface treatment operations.
Plastic media represents cutting-edge technology in mass finishing, combining superior performance characteristics with environmental sustainability, cost-effectiveness, and versatile application capabilities across diverse manufacturing industries including automotive, aerospace, medical devices, electronics, jewelry, and precision component manufacturing.
Plastic media can be used in a variety of scenarios, including deburring, cleaning, polishing, and surface preparation. It is especially useful for finishing delicate or sensitive materials, such as aluminum, brass, and plastic. The media is available in a range of shapes and sizes to suit different applications, and it can be used in both wet and dry processes.
Effective removal of burrs, flash, and sharp edges from CNC machined parts, stamped components, die-castings, injection molded plastics, and precision-manufactured workpieces. Gentle cutting action prevents dimensional changes while thoroughly eliminating unwanted material remnants from drilling, milling, turning, punching, and trimming operations.
Thorough cleaning and degreasing of manufactured components removing machining oils, cutting fluids, stamping lubricants, drawing compounds, rust preventatives, and manufacturing residues. Compatible with aqueous cleaning solutions, alkaline detergents, neutral cleaners, and specialty cleaning chemistry for complete contamination removal.
Precision polishing achieving refined surface textures, satin finishes, matte appearances, and pre-plate surface preparation. Multiple abrasive grades from coarse cutting through ultra-fine burnishing enable progressive finishing sequences from initial deburring through final cosmetic polishing achieving Ra 0.2-0.8 micron surface roughness specifications.
Comprehensive surface conditioning preparing substrates for subsequent coating operations including electroplating (nickel, chrome, zinc, gold), powder coating, liquid painting, anodizing (Type II, Type III hard coat), chemical conversion coating (chromate, phosphate, zirconium), and adhesive bonding applications requiring optimized surface energy and cleanliness.
Plastic media is especially useful for finishing delicate or sensitive materials where substrate protection is critical:
Soft aluminum grades (1100, 3003), aerospace alloys (2024, 6061, 7075), die-cast aluminum (A380, ADC12), extruded profiles, machined aluminum components, aluminum castings requiring gentle deburring without surface damage, scratching, or dimensional alteration.
Free-cutting brass (C36000), cartridge brass (C26000), naval brass, bronze alloys, copper electrical components, plumbing fixtures, decorative hardware, musical instruments, jewelry findings requiring tarnish-free polishing and brilliant surface development without aggressive material removal.
Thermoplastics (ABS, polycarbonate, nylon, acetal, polypropylene), thermosets (phenolic, epoxy), engineering polymers (PEEK, PPS), injection molded parts, 3D printed components (FDM, SLA, SLS), requiring deflashing, gate removal, support structure cleanup, and surface smoothing without stress cracking or surface marring.
Zamak alloys (Zamak 3, Zamak 5, Zamak 7), ZA alloys (ZA-8, ZA-12, ZA-27), zinc die-cast automotive components, decorative hardware, electronic housings, toy components, plumbing fixtures requiring gentle deflashing, overflow removal, and surface finishing without substrate damage.
Components with existing decorative chrome, nickel, zinc, or precious metal plating requiring cleaning, brightening, or final finishing without damaging delicate plated layers. Gentle polishing action preserves coating integrity while enhancing surface appearance and reflectivity.
Tight-tolerance parts, precision instruments, medical devices, electronic components, optical elements, bearing components, watch parts, jewelry findings, micro-machined components requiring burr removal and surface refinement without dimensional changes exceeding ±0.0005" tolerance specifications.
The media is available in a range of shapes and sizes to suit different applications, and it can be used in both wet and dry processes. Our comprehensive plastic media portfolio ensures optimal performance matching your specific part geometry, material characteristics, and finishing objectives.
