Flow Forming

Flow forming is simply a cold forming process by which a thick-walled cylindrical cup called a preform is stretched over a rotating mandrel by three forming rollers, which are arranged equidistant, and at 120 degrees to each other. Six world-class flow-forming machines to maintain the delivery requirements of customers.

Flow forming can be done on different material as below mentioned :

Maraging Steel
Inconel
Stainless Steel
Titanium Alloys
Aluminum alloys
Copper Based Alloys
Steel High Strength Alloys

Capacity:

Diameter - Min 50 mm - 650 mm
Thickness - Min 0.4 mm - 6.0 mm
Length - Max 3500 mm

Forming Possibility

Forward Flow Forming

Forward flow forming is used for components of a closed or semi-closed base. The Preform with the base is mounted on a mandrel and clamped to the hydraulic tailstock. The three working rollers move from the tailstock in the direction of the headstock/gearbox. The component material takes the directional of least resistance and flows in the same direction as the flow forming rollers. The material flow is in the same direction as the roll-direction. This procedure is known as Forward Flow Forming.

Reverse Flow Forming

In tubular component are required without a base then another procedure is used. The roller moves in the same direction as with the forward flow forming that is from tailstock to headstock. The component material again takes the direction of last resistance that is under the rollers and over the mandrel in the direction of the tailstock. Since the rollers are moving in the opposite direction to the material flow this procedure is called Reverse Flow Forming.

Conical Forming

Conical flow forming is used to produce conical or convex components. This preform is from sheet or machine disks. The preform or the disk has the same diameter as the conical tool. The material is deformed in the axial direction. The small the axial angle of the component than the greater is the reduction in the thickness of the component.
