Springs & wire forms

SPRINGS & WIRE FORMS

The primary types of custom springs we provide at Sonfast include compression, extension, Bellville, leaf, and torsion springs, in addition to an array of specialty spring types made from flat or round wire stock. Springs are available in a number of carbon steel, alloy steel, stainless steel, and brass grades, all of which are produced of high quality, ASTM/SAE grade material. Customization options such as closed or open ends, hooks, and hinges, can all be incorporated into the spring design. Custom springs are manufactured either in accordance with customer provided prints, or by specifications that are determined in collaboration with our technical support team. Numerous finishing options which include everything from a simple cleaned and oiled finish to custom colored powder coating are also available.

"I work for a Tier 1 suppler to BMW.  BMW is producing at record numbers and supplying parts on a consistent basis is challenging.  Sonfast is one of my suppliers and they provide excellent product quality and customer service.  BMW often requires additional parts on a very short notice and Sonfast is one of the few suppliers that are always able to accommodate a drop-in order without any issues. I would be most happy if all my suppliers provided the same service and quality parts as Sonfast does."

"Sonfast is more than a supplier, they are a partner and always willing to go over and beyond. On new projects Sonfast team will come in and sit with the design team to review fasteners and suggest what to use and also review all of our current portfolio to make sure we do not add extra inventory. Helping to ensure we use more common lower cost components and not special higher cost fasteners is an everyday example of Sonfast exceeding expectations. Helping with cost, functionality, inventory control, small things that keep us competitive in the market place. Thanks Sonfast Team."

"We started out with Sonfast buying a high volume of one particular screw.  Sonfast was hands down the most competitive price, but even more importantly their ability to manage our inventory.  This kept us a steady supply of components.  We recently added three more high volume precision components for a high end automotive customer.  Many of these parts have long lead times, so it is crucial to have a supplier you can count on to manage inventory and supply chain.  On top of their commitment to maintain supplies, the personal service and relationship that we have developed with the Sonfast crew is hands down on of the best."
