Cut wire shot maintains its peening intensity longer than other types of shot and thus reduces cost.
Cut wire shot is a natural because the peening process requires a round, whole bodied shot that resists rapid change in size and weight to deliver constant intensity. This quality is assured in cut wire shot because the wire from which it has been produced is heat-treated and cold-drawn to achieve hardness and homogeneity. Together with the balanced chemical properties and complete integrity of every piece, this insures that cut wire shot will not fracture in use. It wears down gradually and lasts for many cycles in a peening operation. Tests have shown cut-wire-peened parts have a greater fatigue life than the same part peened with cast shot. This demonstrates that media uniformity is extremely critical for peening.
The larger, huskier bodies of cut wire shot can clean faster. That is why cut wire is used to clean all types of metal. A cut wire cleaned surface is exceptionally bright and smooth. Our pellets are whole-bodied shot with no scale or oxides present. As a result, they create no dust and leave the PelletsLLC.com – Copy Document – 07.05.16 – Page 45 of 78 surface clean.
Cut wire can be used for tumbling and vibratory finishing. The cylindrical form of the particles offers superior penetration into the fillets or recessed areas so important in this work. (Longer lengths are available where deep penetration is required.) Where magnetic separation is desired, cut wire of brass or type 316 stainless and zinc may be used. Available sizes range from wire diameters of .012 inches (.30mm) to .125 inches (3.17 mm) and lengths up to .5 inch (12.7 mm).
For Plating Filler
Cut wire pellets can be used for “fill” in metal plating applications where the amount or volume of product to be plated is not sufficient enough in a bulk plating process.
The pellets carry electrical current throughout the plating cycle preventing “make and break contact” which could otherwise result in arcing and damage to customer product. Pellets can be used to bring the volume of parts in the bulk processing unit (barrel) to a level where continual electrical current flow occurs, eliminating the potential for damage and/or insufficient plating thickness. The pellets then can be stripped of their coating and used again. Depending on the plating process and subsequent stripping method, carbon steel or stainless steel can be used. Another benefit of the application is that it assists in keeping parts from “stacking” during the plating process, resulting in better plate thickness distribution.
