Metal forming, is the metalworking process of fashioning metal parts and objects through mechanical deformation; The work piece is reshaped without adding or removing material, and its mass remains unchanged. CSMFG is an American owned company with experience in metal forming since 2003. Our roll forming process begins by passing a long strip of coiled metal through a series of incremental bends until a final cross-section profile is achieved. Besides, our team of roll forming experts can apply further improvements.
Roll forming is ideal for economically producing high volumes of close tolerance parts with a wide range of geometries. Our roll forming process makes metals into hardened states so that lower labor costs can be reached.
Advantages of roll forming
- Replace higher cost plastics and extruded parts
- Reduce waste, secondary operations and labor costs
- Compatible with both ferrous and non-ferrous metals
- Fabricate finished or painted parts
- Broad range of geometric opportunities
Roll forming capability
Roll forming machines are available that produce shapes of different sizes and material thicknesses using the same rolls. Variations in size are achieved by making the distances between the rolls variable by manual adjustment or computerized controls, allowing for rapid changeover. And, Tolerances can typically be held within ±0.015 inches (0.38 mm) for the width of the cross-sectional form, and ±0.060 inches (1.5 mm) for its depth.
We use different kind of forming to achieve the most cost effective solution for our customer
Extrusion - where the material is pushed through an orifice
Die forming - where the material is stamped by a press around or onto a die
Forging - where the material is shaped by localized compressive forces
Intending - where a tool is pressed into the work piece
Stretching - where a tensile load is applied along the longitudinal axis of the work piece
Expanding - where the circumference of a hollow body is increased by tangential loading
Recessing - where depressions and holes are formed through tensile loading
Combined Tensile and Compressive forming
Pulling through a die, deep drawing, spinning, flange forming, upset bulging, roll forming
