Flat Forms & Strip Forms
The Newcomb Spring Corporation offers a wide range of form manufacturing capabilities to produce flat forms and strip forms, including small metal stampings. Parts are produced on four-slides, verti-slides and specially built multi-slide machines, though most often components are manufactured on power presses using a die set created for a specific part. Often our flat forms and strip forms are fabricated in conjunction with other parts and assembled to customer specifications.
Our material size range for these components is .004-inches to .125-inches thick and up to 5.0-inches wide.
Production & Design
Newcomb Spring is equipped to produce flat forms, strip forms and small metal stampings in small quantities from sheet material or etched blanks. For large, high-volume manufacturing runs, we typically utilize hard tooling. Newcomb often recommends that customers order a short run of parts to verify a component's functionality, avoiding costly design errors.
The extensive variety of equipment we utilize to produce flat forms and strip forms, combined with our use of form tools, allows Newcomb Spring to create complex shapes as well as produce die-sets which can be used for cutting, etching, extruding, notching, swedging, stamping and more. Our facilities also offer primary and secondary operation departments which work to produce components of short order flat forms made from blanks produced by etching, EDM or simple dies.
Whenever possible strip forms and flat forms should be designed to bend against the grain of material (i.e. perpendicular to the grain) to improve life expectancy and reduce the risk of fracturing.
Material Considerations
Newcomb Spring is capable of manufacturing parts using any material, though typically we produce flat forms and strip forms from continuous coil material. The most frequently chosen coil materials are #3 slit edge, #5 deburred edge and #1 round edge. The main differences among these options are:
- #3 slit edge is often used when a die cut eliminates the edge of the material; when edge condition is not critical to a part's fit, form or function; or when costs prohibit other edge options.
- #5 deburred edge is often used when the edge condition is critical to a part's fit, form or function. This edging option offers improved safety in part and stock handling, as the edging process produces broken corners instead of square corners.
- #1 round edge is one of the safest material options in terms of handling parts and stock. As well, this edging increases the cycle life of torsion springs and leaf springs.
