OSVA, thanks to the solid know-how of the latest forging technologies has captive capabilities to manage with its customers every since step of the production process, from design to finished product
The raw material is a key element of the finished product, therefore OSVA buys steel only from approved and certified steel-makers. Along the overall production process, the steel is traceable through identification methodology witch makes extremely unlikely the mix-up of different grandes.
Racks and location of each individual steel heat are manged in real time thorugh bar-code within the ERP. Each rack is allowrd to stock only a single heat/section and such information is the electronically managed along the production cycle.
The current best practices in the forging industries encourage co-design with customers at a very early stage, with the target to optimized the geometry, the amount of stock removal and, finally the component cost. The OSVA engineering team is able to carry-on simulation process on 3D-CAD in order to optimize the foring die well affort starting the prototyping process.
OSVA has in-house capability to both design and manufacture tooling and dies.
This value added allow high flexibility as well as total confidentiality about customers drawings and products. The captive know-how for dies and toolings (forging and extrusion) is also a key factor to keep the lead in innovative technologies.
The forging process develops along the following main steps:
- cold or hot smearing of the billet
- pre-formin
- forging
- hot extrusion
- trimming/deburring
- cold coining (when requested)
The process in then computed with heat-treatment, isothermal annealing, quenching and tempering, controlled cooling, sand blasting, packaging.
Our customes are more and more interested to buy semi-finished components; for such reason OSVA has put in place the resources to manage the out-sourcing of heat-treatment, surface treatment (if any) and machining (turning, milling, drilling, etc…)
During the different steps of the production process we carry-on several type of controls, namely: metallurgical, dimensional and integrity (magnetic particle snspection) as the final product quality is highly affected from the raw material quality, each individual steel heat is fully certified from the steel-maker, double checked at OSVA with the portable spectometer and other tests, when requested, executed from a certified metallurgical lab.
