-   dispatch according to customer’s specification


 
Development and manufacture of drope stampings
 •  our own construction and technology of forgings and forge tools
 •  3D CAD software – Catia, SolidEdge, 2D + 3D simulation of forming 
     - Simufact
 •  production of drope stampings of steel weight category 0,1-20 kg
 •  our forgings are forged at modern forging lines  (photo of machines)
 •  induction heating of material with blank sorter
 •  possibility of controlled cooling from the forming temperature

Our own manufacture of forge tools
 •  manufacture on conventional and CNC machines
 •  functional surfaces exclusively manufactured by applying the CNC 
    technology and using the CAM software POWERMILL
 •  3D control of execution 

Material division
 •  cold division on SCHUBERT STS 450 shears – bar steel of round 
    cross-section from D25 to D90
 •  other dimensions on Behringer band saws

Thermal treatment
 •  normalization, soft annealing, solution annealing, stress relieving annealing, 
    BG annealing
 •  refinement
 •  surface and high-frequency hardening (for guidance  D15-90 mm)
 •  cementing in gas atmosphere (gas carburizing)
 •  ensuring the required material tests

Forgings surface treatment
 •  blasting with the steel granulate
 •  check for surface cracks - magnetic defectoscopy
 •  check of material structure - Eddyliner
 •  calibration and cold forging
 •  electroplating 
 •  forgings varnishing

Forgings machining
 •  CNC chip working of forgings
 •  finalization into simple sets
 •  Just in time “deliveries to customers

The whole manufacturing process quality inspection
We gained a reputation and international references as the subcontractor for car industry, building industry and agricultural technique.
Our processes are certified according to VDA 6.1, ČSN EN ISO 9001:2009 and ČSN EN ISO 14001:2005. When aiming to provide our customers with faultless products we work with Zero-fault strategy.

Dispatch according to customer’s specification
We provide the transportation in packages according to customer’s specification including the required accompanying documentation.
