ISF Process

Incremental Sheet Forming (ISF)

“now here in the UK”!!

ISF is an incremental sheet forming process suited to low volume and one-off manufacture. ISF utilises a very small tool contact area to achieve controlled deformation with low applied loads and very high accuracy. The tooling costs and lead times are a fraction of what is currently used in traditional sheet forming operations. The ISF process uses a gantry based tool mounting or robot mounted tools to increase the working envelope and facilitate the simultaneous operation of multiple tools.

  • Aluminium
  • Mild Steel
  • Stainless Steel
  • Copper
  • Magnesium

The investment in tooling is minimal, a ‘form tool’ is made from medium density model board. This former can be modified as the part design evolves.

  • The investment in tooling is minimal, a ‘form tool’ of medium density model. This former can be modified as the part design evolves.
  • Low tooling costs and reduced lead times.
  • High tolerance and level of detail on parts.
  • Low volume, on-offs, and variants produced easily.
  • Ability to work hard materials and large working envelope.
  • Incremental deformation using small tool contact areas minimises applied force and spring back.
