Great strength and low material use

Spinning

Lower resource consumption and reduces weight…

Roll forming is a resource-saving process that improves the product properties, compared to alternative processes.

How does spinning reduce the resource consumption?

  • Spinning reduces material waste
    As spinning is a chip-less process, the material waste is reduced.
    Also spun items, often can be manufactures using a thinner material, without compromising product strength. In that way both material consumption and weight are reduced.

  • Spinning reduces energy consumption
    Spinning is a cold process. Therefor you save the energy related to heating up metal, which else would have been required if using a casting process.

Spinning’s resource-saving properties, makes the process attractive when manufacturing new products in large volumes, or in relation to a cost-down project on an existing product.

Which properties does spinned items have?

  • High strength
    In spinning, rolled sheet metal is formed through a cold machining process, Cold processing of sheet metal, does not contain gas bobbles in the material, contrary to a casted item. Gas bobbles makes the material porous, so by preventing them, the material remains strong.

  • Smooth and homogeneous surfaces
    As gas bobbles in the material is prevented in spinning, the irregularities caused by these bobbles on the surface is also prevented. Also, ash-marks from embers in a casting process is prevented using a spinning process.

We have experienced a high demand for spined pulleys. This is because that spined items high strength increases durability and their low weight reduces the inerti, as less material is rotated by the engine. That reduces the engines fuel consumption.

Which tasks can we solve using spinning?

We can perform both Poly V spinning and V-belt thin sheet spinning.
We master Poly V spinning in up to 12 mm thickness and up to 800 mm diameter.

V-belt thin sheet spinning can be performed in up to 2.5 mm thickness and up to 360 mm diameter.

We can combine spinning with e.g., deep-drawing and fine blanking. The items can also be hub-formed in the spinning process.
