ISF makes sheet forming fast, flexible and profitable, also for short production runs

Free-form sheet metal components are frequently used in the manufacturing industry, although producing them is often expensive and laborious, particularly for short production runs and prototypes. ISF (incremental sheet forming) offers sheet metal-working companies enormous potential for making economically efficient short production runs of 3D shaped sheet metal components.

Free-form sheet metal components are frequently used in the manufacturing industry, although producing them is often expensive and laborious, particularly for short production runs and prototypes. ISF (incremental sheet forming) offers sheet metal-working companies enormous potential for making economically efficient short production runs of 3D shaped sheet metal components

The technology can be used to complement existing technologies, or for producing specific sheet metal components with free-form product features that are difficult or not economically viable when using traditional methods.

Technology

By combining ISF with other sheet metal work processes with their own specific advantages, it is possible to achieve further reductions in production costs. This in turn should lead to greater design freedom and therefore new products and applications.

There are three different methods, depending on how the blank sheet is supported:

  • TPIF (two point incremental forming) uses a full or partial matrix to support the workpiece during formation;
  • Best known and commonly used is SPIF (single point incremental forming), where a matrix is not used and the sheet is held in a clamp, usually in combination with a backing plate;
  • KISF (kinematic incremental sheetmetal forming) is a variation that uses two pins, where one of them acts as the shaping tool, while the second pin gives local support to the other side of the sheet.

Applications

Examples of possible applications can be found in a whole range of different areas:

  • architectural 3D shaped structural external wall components for modern buildings and structures;
  • all sorts of products for the automotive industry, such as bodywork prototypes, individualized components for top of the range vehicles;
  • sheet metal components or moulds for plastic or composite components for aircraft, aerospace, sanitary fittings, etc...
  • components for wind turbines;
  • storage tanks for foodstuffs, fluids and gases;
  • customised furniture and internal wall dividers;
  • patient-specific orthosis and implants

Application lab

In collaboration with KU Leuven, Sirris has created an application lab thereby ensuring that all the existing knowledge and experience is transferred to industry. The lab also gives industry access to its infrastructure, knowledge and technological support, as well as providing an opportunity to explore and test out the technology for themselves.

Over the coming months Sirris is planning to publish a series of articles about potential applications with ISF. Would you like to receive the latest articles as soon as they are published? Register now and receive the link to these publications in your mailbox!
