Beads Glass Beads Efficiency, quality and recycling are important in the modern metal production process. Our company provides technology integrated glass beads in various fields such as the aircraft industry, auto industry and electronics industry, creating cost reduction. Especially they show excellent performances in the processes of cleaning, peening, finishing and deburring, all concerning the sand blasting process. Finishing What matters the most outwardly is the bead size. Speed, nozzle angles and other elements should be adjusted along with the maximum working speed and minimum consumption rate. In general, high strength large beads provide deep matte, low strength large beads provide smooth and bright surfaces, high strength small beads provide dull matte, and low strength small beads provide bright satin. Advantages : Wide range of glass finish from matte to stain, recycling finish with an easy process Cleaning Widely used, it often applies effectively to the angle tests of different nozzles. Small size range is well suited to internal grooves or hard parts. High speed and minimal labor are required. So size and nozzle angles should be combined well. In general, optimal cleaning speed by the given size optimizes consumption and reduces costs. Advantages : No scars on the working plane, chemical inactivation, extensive and fine cleaning, high energy efficiency by use Application : Scrap removal or vat, tube, tray, household goods, and a tank; cleaning of machines, dies, plates removal of surface scraps or coating, keeping piston and block clean in the engine recycling process, cleaning large tubine, engine casting, further complex parts Application : Most interior ornaments, mixed surface defects, printing plate/dies, cast etching, casting scar removal, cleaning cast surface and doubling the softness Deburring Top consideration in deburring should be the combination of procedures in the surface finish process to acquire enough energy for restraining or removing barr. Bead sizes should be adjusted by speed and peening strength. Moderate nozzle angles optimize consumption. Advantages : Barr removal, cost reduction by the one-step process Peening The hammering process requires peening to increase fatigue resistance or internal tension corrosion. Glass beads work well particularly in penning because they never give any damage to the surface metal. Application : Removing ends of tools, systems, and finished products, as well as barr removal; Deflashing and deburring of plastic parts and metal casting; Removing barr of threading equipment and spool Advantages : Anti-crack and increased life, excellent for precision work, peening no scrapes on working plane, no need of follow-up treatment following scar removal POTTERS INDUSTRIES INC (USA) POTTERS INDUSTRIES INC (Australia) POTTERS BALLOTINI IMPACT BEADS POTTERS BALLOTINI IMPACT BEADS Particle Size MIL 3,4,5,6,7,8,9,10,11,12,13 MIL 6,7,8,10,11 Potters D,AC,AD,AE Packing 25kg 3 layer paper bag Application - Peening to prevent severe corrosion or cracks in specific parts - Peening for gear, shaft, cutting blades, cutting tools, pipe, joint and spare parts, to raise resistance against severe corrosion or cracks - Peening to boost resistance against weekend materials of the body and propellers - Peening of blades in jet engine parts, windsock, valve, spindle, and shaft POTTERS BALLOTINI IMPACT BEADS (USA) POTTERS INDUSTRIES INC.
