Precision Springs and Wire Forms
Precision Springs -- made in compression, extension, and torsion types. They can be produced from wire with diameters from 0.004" to 0.625". These three types of springs can be made in diameters up to 6" in single prototypes or millions of parts.
Ferrous and nonferrous materials are used to fabricate springs: music wire; phosphor bronze; hard-drawn; oil tempered; carbon vanadium; chromium; silicon; 302, 304, 316, and 17-7 stainless steel; Inconel® 670, 718, and 750; Monel® 400; beryllium; copper; and aluminum wire materials makeup the list. These materials are held to precise specifications such as MIL-45208A and/or ASTM Standards.
Computer Numerical Controlled (CNC) machines are used to form precision springs. Manufacturing facilities can also include secondary machining equipment such as grinders, formers, burnishers, shot blasters (peening equipment), stress relievers, or heat treating furnaces. Some companies also provide multiple function assembly or component manufacturing operations to accommodate product requests such as extension springs with end pieces. With this type of request the springmaker can also manufacture the component that the customer orders, thereby eliminating the need to move the spring production lot to an off-site location for the assembly or manufacture of any attachments. Cost savings are realized in direct proportion to the number of operations done in-house by the springmaker.
Wire Forms -- made of wire in diameters from 0.030" up to 0.312" with a maximum material length of up to 30".
Spring and formed wire products described herein have applications on bicycles, servomotors, valves, meters, automobiles, and equipment used by utilities.
Products that conform to quality specifications in the order and company certification to particular ISO (International Standards Organization) methods are recognized as enhancements to company activities.
MONEL and INCONEL are registered Trade Marks of Special Metals Corporation
