Wire forming is a term that incorporates many shapes, sizes and dimensions. The forms are engineered in two or three dimensions and commonly generated from coils of metal wire. In some cases, the raw material commences production in blank forms that are fed from a hopper.
A wire form may be defined as any length of wire that has had some force applied to it that changes its shape. Wire can be round, flat, hexagonal, square, oval, triangular, elliptical or D-shaped, just to name a few. Wire can be made of low-carbon steel, medium- carbon and high-carbon steel. It can also be made of stainless, aluminum, copper, brass and an assortment of other alloyed materials. Wire Forms include, clips, coiled parts, display stands, fittings and fixings, hooks, baskets and welded wire fabricated assemblies.
Examples of Wire-Formed Parts:
Industry sectors utilizing wire formed components includes agriculture, automotive, cable management, construction, display, electronics, engineering, furniture, garden, healthcare, horticulture, industrial, insulation, leisure, medical and pre-cast concrete, and retail.
In wire forming, force is applied to change the contour of wire by bending, swaging, piercing, chamfering, shearing, or other techniques. The various techniques for wire forming can produce any type of shape, form, or configuration. The process starts with coiled wire that is straightened before being formed.
Common metals used for wire forming include steel, brass, stainless steel, copper, aluminum, and a variety of different alloys. The diameters of wires vary from 0.5 mm to 6.5 mm, or 1/64th of an inch to a quarter inch and can produce 2 and 3 dimensional wire forms.
With many manufacturers, hard tooling is required to form specific wire shapes. However, we have multiple CNC wire formers that only require programming to achieve a desired shape. We generally do not require hard tooling of any kind.
