Wire Divider

Due primarily to its superior Durability and Resistance to Fracture as well as the absence of Iron Oxide coating, Cut Wire Shot provides cost savings associated in Media Consumption, Dust Generated and removal of Surface Contamination.

Media Consumption - Durability testing can be done to measure representative media life (in cycles) or breakdown rate (in grams per cycle). By multiplying the breakdown rate (grams/cycle) by the cost of the media ($/gram), one can determine a relative cost per cycle ($/cycle)

e.g.:

CCW35 - Breakdown Rate measured as 0.038 g/c, and
Cost = $0.00227/g.
Cost per cycle = 0.028 g/c x $0.00227/g=$0.000086/cycle.

CS330 - Breakdown Rate measured as 0.158 g/c, and
Cost = $0.000937/g
Cost per cycle = 0.158 g/c x $0.0009937/g=$0.000148/cycle.

The media consumption cost of CCW 35 is 58% that of the S-330 shot.

Dust Generation - During Durability testing, and also during use, the Dust Generation Rate (DGR) of a particular media can be determined. If 100 grams of media is tested in a life Tester, a small amount of the sample will exit the test machine as dust. The amount of dust lost divided by the Number of cycles tested gives the DGR in grams per cycle (g/c). Cut Wire Shot generates much less dust than other media, and therefore cost of dust disposal can be reduced.

e.g.:

The cost in Cleveland, Ohio to dispose of one 55 gallon drum (containing 800 pounds of non-hazardous metal dust) is about $55.00 or $0.000152/gram.

DGR of CCW35 = 0.0147 g/cycle
Cost of Dust Removal = 0.0147 g/c x $0.000152/g = $0.0000022/cycle

DGR of CS330 = 0.0254 g/cycle
Cost of Dust Removal = 0.0254 g/c x $0.000152/g = $0.0000039/cycle

The cost of dust removal of CCW 35 would be 56% that of the S-330 shot.

Surface Contamination - Studies have shown that the residue left on the surface of a blasted or peened part are much less (as much as 10 to 15 times less) with cut wire shot compared to cast shot. On steel parts, the residue (Iron Oxide) is not normally objectionable. But on non-ferrous parts, it should be removed. Decontamination processes (chemical decontamination is normally preferred) can be costly, dangerous to personnel, and require disposal of spent chemical solutions. With surface residue significantly reduced, decontamination time is also reduced. Exposure of personnel to potential safety hazards is lessened and replacement of spent chemical solutions is less frequent.
