Wire Forms and Flat Springs have few limits when it comes to applications. The constraints are usually in the form of materials. We can and have formed many different shapes from round wire and flat materials. Four slide tooling offers many advantages over conventional punch press tooling. There are a few advantages with wire forms and flat springs, such as the material is purchased to finished width reducing scrap, no die set is needed, material can be formed past 90 degrees, and flat or round material can be formed in a Four-slide.
The four-slide produces high volume parts with hard tooling. When lower volume is needed, CNC wireformers and proprietary tooling are used. Forming can be done in low or high volume for either spring tempered material or mild steel. We can provide minimum bend radius information if needed.

Spring materials are available in many sizes and types. The top four being:
1) MUSIC WIRE
2) HARD DRAWN
4) STAINLESS TYPE 302 for heat and corrosion resistance.
Most wire forms are made from low carbon steel wire, 1008-1018. The shape of the wireform is only limited to your imagination and application.
Using low carbon allows the parts to be welded if needed. Stainless is also available in annealed and quarter hard.
Other grades of stainless and tempers may be a special order which require certain minimums. If additional toughness is needed, most wire forms can be manufactured from spring wire, but they have forming limitations.
Please consult us and we will work with you achieve the best results.
Most wire forms can be plated, but some may require rack plating. Rack plating is an extra cost over normal barrel plating. However, another option is to run the parts from pre-plated material, typically a galvanized zinc finish.
Flat springs are typically made from pre-tempered material or from annealed material and then heat treated.
These springs can be produced from carbon steel or stainless steel.
The carbon steel parts will normally have to be plated to prevent corrosion after the heat treatment process.
We can assist in the design of these springs, and we are able to produce prototypes for a nominal cost to prove your design.
RECTANGULAR BAR STOCK FORMS
We also form rectangular or square bar stock to your drawings. These are normally low carbon material, but spring temper material is available.
We can provide drilled or punched holes are needed.
