Technologically developed production

At the Blaj company, we pay great attention to the quality as well as to the constant technological development (we invest in new and improve already technically advanced equipment), since we want to provide our customers with refined special fasteners and services.

Production takes place in the following stages:

1. Material sawing.
   
   
   
2. Hot forging from M6 to M72, inductive heating, determination of heating parameters by pyrometer ( whereby the forging as such means an improvement of mechanical properties and the material structure).
   
   
   
3. Normalizing, quenching and tempering, quenching of austenites and carbonisation at our own heat treatment facility.
   
   
   
4. Conventional turning on CNC lathes: from 5mm - to 100 mm and special machining of longer workpieces on CNC lathes: from 8 mm - to 70 mm; length: max. 1000 mm.
   
   
   
5. Grinding (also centreless).
   
   
6. Milling.
   
   
7. Deep drilling.
   
   
8. Thread rolling, also after the heat treating of 12.9 (metric threads, UN, UNC, UNF, Withworth, or according to the client's drawings). By rolling we achieve an improvement of mechanical properties due to the course of force lines with regard to the thread form, a cold solidification of the surface, a decrease of surface roughness and the resulting decrease of the friction coefficient.
   
   
   
9. Ribbing.
   
   
10. Inductive heat treatment.
