Calibration: added value for downstream processes
Calibration at SIFCOR is an essential complementary process to hot forging, capable of achieving tight dimensional and geometric tolerances. Thanks to this precision step, forged parts benefit from improved surface quality and optimal repeatability.
For the customer, this means greater performance, better integration into assemblies, and reduced machining operations. This mastery of calibration thus strengthens the reliability of the finished product while optimizing costs and lead times.
Skills and technologies
- Cold calibration : press operation for cold reworking of the most precise or most critical areas of the forged blank and improvement of its surface finish.
- Cold punching and piercing: the most economical way to create holes, an alternative to hot piercing and machining for intermediate tolerances.
- Straightening: for very thin or very long parts, which are sensitive to hot deformation, this operation improves product flatness.
- Preparation for machining stages: cold calibration provides the machinist with reference points that support process repeatability.
Our strengths
Sifcor has always combined hot forging and cold calibration, giving its customers the best of both technologies:
- A proactive approach from the design stage: our design office selects, as early as the quotation phase, the operations best suited to our customers’ needs. Mastery of cold calibration technology is an additional asset in achieving the best technical and economic balance.
- Autonomy: Sifcor fully masters the design and manufacture of its calibration tooling. This ensures responsiveness and quality.
- Versatile machine park: all SIFCOR sites offer calibration operations thanks to machine parks adapted to their range of products.
- Calibration and final inspection: SIFCOR limits reworking operations by combining calibration with final inspection and packaging, thereby optimizing finishing costs.
As with all its processing operations, SIFCOR makes technical choices that offer the best technical and economic trade-offs. Calibration and all cold operations fully contribute to this objective.
