Products
We manufacture made-to-order or custom precision springs and wire forms. About half of our sales are from wire forms and half are from springs. Precision means they are used where exact tolerances are critical.
We also can be a more economical source for standard or catalog springs when your quantities get above 500 pieces per order. Most of our business comes from orders with quantities from 1 piece (rapid prototypes) to 500,000 pieces.
