Cold formed parts
For economical large series
Precisely shaped under high pressure - cold forming is an established basic technology at SFS, with which we manufacture precision moulded parts and special screws. It is a highly efficient and precise mass production process that is particularly suitable for large batch sizes.
Characteristics
Materials
- Steels with low carbon content
- Case-hardening and heat-treatable steels
- Corrosion-resistant chrome and chrome-nickel steels
- Magnetic soft iron
- Aluminium alloys
- Copper alloys
- Special steels
Additional machining
- Machining operations
- Applying threads (rolling, rolling, thread moulding)
- Heat and surface treatments
Machinery
- Double pressure presses
- Two-die three-stroke presses
- Multi-stage presses (up to 6 forming stages)
Quantities
- Double-stage parts > 10,000 pieces/year
- Multi-stage parts > 250,000 pieces/year
Dimensions
- From wire Ø of 0.5 to 50 mm
- Lengths from 3 to 300 mm
Application - pressure cooker
Here, an expensive turned part was replaced by a cost-effective cold-formed part. Dimensional accuracy and welding behaviour were also improved.
