Customer Case Study: Improving the Shock Absorber and Cylinder Assembly Process
Context
During the final assembly of the shock absorbers, the tube (filled with oil and with the rod extended) must be closed by folding its end over the seal-bearing. The traditional radial roller head crimping process generated irregular axial deformations, reducing the service life of the parts and increasing scrap.
Solution
The company has adopted a GUILLEMIN orbital riveting unit (6 tonnes thrust, 300 mm stroke). This system, equipped with a hydraulic blank holder and a control automation, guarantees:
– Optimal positioning of internal components
– Precise control of parameters (time, pressure, distance)
Results
Reliability and quality
– Less waste and better preserved parts
– Total control of internal deformations and constraints
– Impeccable aesthetic rendering
Flexibility
– Precise speed and pressure settings.
– Reduction in the number of tools required.
Productivity
– Cycle reduced to 8 seconds
– Quick tool change
The GUILLEMIN solution has enabled a significant improvement in quality, flexibility and productivity. This process illustrates how crimping technology can transform a complex process into a strategic advantage.
