We are able to produce steel die forgings of the most challenging designs with complex dividing plane in different categories from 0.1 kg to 50 kg of all usual steel grades in the highest quality of processing.
Limit combination of dimensions or the great complexity of the dividing plane and design, requires our individual assessment of manufacturability. Materials - structural, carbon, alloy, microalloyed ,stainless steel according to ČSN, EN, DIN, IASI and specific customer requirements.
We offer the production of small, medium and large series, as well as the production of prototypes that we provide with 3D technology.
We use forging lines with crank forging presses to produce steel die forgings.
Forging lines have induction heatings with precise regulation and sorters of overheated or unheated pieces. The forge is equipped with many forging lines.
Continuous heat treatment lines are used in the production of die forgings.
We also have hardening shop where we apply the right heat treatment for your parts.
All our production processes are certified. We care about the highest quality of processing and consistent quality control for all our products.
We have a quality system with all the modern methods for checking the quality of the entire production process, from purchasing material through continuous production control to final inspection before shipment.
In an effort to provide for our customers technically perfect product, we are working with a minimal defect strategy.
We offer the following operations of forgings by the surface treatment :
If requested by customers, we can also carry out a 100% check for surface defects using a magnetic flux machine. We also have our own 3D measuring facility.
We have all the conventional technologies for machining forgings.
Our range of services includes machining of steel die forgings, especially milling and turning operations on CNC machines.
Depending on customer requirements, we can also offer co-operation with other factories.
We provide transportation of forgings in packages according to the customer's specification, we use wooden boxes or plastic pallets, gitterboxes, including the required accompanying documentation. We ship the goods according to Incoterms 2017 (FCA, DAP or EXW .)
