Assembly: the final step towards the finished stud
After the cold-forging stage — and rolling, where required — comes assembling: a key step that transforms the body into a finished stud ready for delivery to the customer.
This process involves inserting the tungsten carbide pin into the body previously produced using our two metal wire forming techniques. Assembling therefore joins the two components of the stud — the pin and the body — by means of shrink fitting.
Precision work
A precise operation tailored to each stud design
Each stud model requires specific tooling, defined according to its shape, size and the customer’s technical requirements. We therefore adapt our assembly lines to ensure perfect positioning of the components, using for example:
- Vibratory bowls to correctly orient the parts;
- Feed tubes to guide the pins and casings;
- Presses to carry out the assembly operation, ensuring a strong and durable bond.
Essential expertise
As with the previous stages, precision and rigour are paramount. We carry out inspections at every stage of production, following dedicated procedures and using tools adapted to each type of component.
To guarantee consistent quality, each machine is equipped with monitoring systems, including control cameras and SPC (Statistical Process Control) devices, enabling the automatic detection of any deviation or non-conformity.
