		Cold Formed Aluminum Specimen Mount for the Scientific Industry At Skach Manufacturing Company, we are often able to provide customers with a low cost alternative to the screw machine process. The part shown is used in the scientific and medical industry. This stud was originally manufactured using a screw machine process. A large amount of aluminum waste was generated due to the difference between the head and the shank diameters. Skach designed a cold forming process that uses a multi-station heading machine to form the blank. This process eliminated the bulk of the waste material and met the tight screw machine tolerances. A secondary grooving (trim) operation was required to complete the stud. The stud is finished in a tumbling operation to provide a uniform finish on the surface of the ...




		Cold Forming of a Brass Stud for the Electronic Industry At Skach Manufacturing Company, we successfully convert screw machined components to the cold forming process. It is rare to simultaneously reduce costs and improve quality, but that is precisely what our team was able to do in the highlighted project. The part pictured is a brass stud that is inserted into a plastic molded electronic switch. The customer was using a screw machined stud but the part was not able to meet the specified torque requirement. Working with the customer, we revised the design of the stud for cold forming and two secondary operations. We produced a stud which met the torque specification and provided a significant cost reduction. Several other studs were also converted to cold forming, which has provided ...




		Cold Forming of an Aluminum Pneumatic Valve Stem for the Automotive Industry At Skach Manufacturing Company, our ability to manufacture complex custom components, using the cold forming process, provides our customers with a cost effective alternative to the screw machine process. In this example, the customer originally designed the valve stem for cold forming; however, the customer’s request for quotation was rejected by other cold forming suppliers. They all requested design changes that were not acceptable, and machining the part would have resulted in a significant increase over the customer’s target cost. The screw machine process was too slow and generated a significant amount of material waste due to the large difference between the head and the shank diameters. Skach was contacted for input on the ...




		Screw Machine Conversion of a Brass Shaft for an Electronic Switch The cold forming process in conjunction with in-house secondary operations provides Skach Manufacturing Company the capability of producing a wide variety of products. The highlighted shaft is used in an electronic switch. The customer initially dismissed a cold formed part because of the numerous secondary operations needed to complete the part. Skach’s design team successfully cold formed a blank with secondary operations at a lower cost to the screw machine alternative. A blank is first cold formed out of CDA 260 brass. Secondary operations include knurling, trimming and thread rolling. The 1.745" long shaft is then finished with a nickel plate. Diameter tolerances are held within +/- .001" and the concentricity tolerances ...




		Cold Formed Copper Terminal for the Automotive Industry By remaining at the forefront of manufacturing technology, our team at Skach Manufacturing Company continues to provide customers with innovative cold forming solutions. The part shown here is a copper terminal that is used in an automotive switch. The terminal acts as the base for a toggle mechanism and is centered on a concave surface. To remain properly aligned in the switch, the shape and finish of the concave surface are critical. The customer had initially designed the part for a screw machine process but was unable to achieve acceptable results. Prior to contacting Skach, the customer had suffered another setback when a different cold forming manufacturer was unable to produce the concave section without cracking. After the ...
