Technological Equipment

  • Online mode of the technological operations' monitoring system
  • Electronic archiving of heat treatment parameters
  • Detailed documenting of carried-out heat treatment processes

Treatment in a controlled atmosphere through our set of multi-purpose chamber furnaces

Case hardening-Carburising and carboinitriding
Hardening and treatment with oil quenching,
Tempering-low-temperature and high-temperature
Annealing-recrystallization, internal stress reduction, softening, and normalization

This is carried out in our set of multi-purpose IPSEN chamber furnaces with batch dimensions of 400 x 600 x 900 mm, with a programmable automatic operating mode and control of the atmosphere carbon potential through an oxygen probe.
This is suitable for demanding, small and large-scale production.

Processing in the controlled protective atmosphere of pit furnaces

Case hardening-Carburising
Hardening and treatment with oil quenching,
Tempering-low-temperature and high-temperature
Annealing-recrystallization, internal stress reduction, softening, and normalization

This is carried out in a set of pit furnaces with batch dimensions of O 700 mm x 2000 mm (max. 900 kg/batch) with oil quenching.
This is particularly suitable for long rotating components, piece and series production.

Treatment in pit furnaces-Nitriding

Gas nitriding
Creation of very hard surface layers
Anti-corrosion nitriding

This is carried out in a set of pit furnaces with batch dimensions of O 700 mm x 2000 mm (max. 900 kg/batch)

Salt bath treatment

Hardening and annealing with heating in a salt bath with temperature up to 950°C
Quenching and marttempering in an AS 140 salt bath in a temperature range of 160°C-250°C
Isothermal hardening (austempering) and treatment in a salt bath with a temperature of up to 450°C for steel, cast iron, and ADI
Tempering in a salt bath with a temperature of up to 450°C

The maximum equipment working dimensions are 600 x 500 x 750 mm.
Heating in a non-toxic salt bath (K750). Hardening in an AS 140 salt bath, oil, or water.
This is suitable for parts with complex shapes with the risk of deformation upon heat treatment.
Both, piece and serial production

Treatment in air furnaces

Hardening and treatment with cooling in oil and water, low- and high-temperature tempering, and annealing. The heat treatment is carried out in our set of chamber furnaces (batch dimensions of 600 x 500 x 1000 mm) and bogie hearth furnace (batch size 2000 x 1000 x 550 mm).

Heat treatment of Al alloys

Dissolving annealing and hardening
This is carried out in our set of shaft tempering furnaces (batch size of O 700 x 1,000 mm) and low-temperature tempering furnaces for Al-alloy hardening (batch size of 1500 x 1200 x 600 mm).

High frequency hardening

The HF surface hardening of rotating components is carried out through induction heating with water cooling. The hardened layer depth is approx. 0,5-2,0 mm. The hardened part's max. dimensions are O 420 mm with a clamping length of max. 500 mm (the shape, size of parts, and especially the shape and parameters of the hardened surface must be consulted with us before their treatment).
We also perform high-frequency hardening of small parts from the hand.

Medium frequency hardening

MF surface hardening of rotating components is carried out through induction heating with water cooling in our modern CNC equipment. The hardened layer depth is 2,0-8,0 mm. The hardened part's max. dimensions are Ø 200 mm with a clamping length of max. 2100 mm, with a hardened area length of max. 1900 mm (the shape, size of parts, and especially the shape and parameters of the hardened surface must be consulted with us before their treatment).

OTHER OPERATIONS ASSOCIATED WITH HEAT TREATMENTS

Straightening

We straighten parts of various types and shapes in both cold and hot conditions.
Straightening is carried out in our spindle and hydraulic presses (even hot) or through manual part surface filament tapping. We carry out flame straightening as well.

Blasting

We perform both manual and machine blasting.

Technical Support

Technological development, analyses and examinations, material analyses, material and technological consulting (metal heat treatment), mechanical tests and defectoscopy in cooperation with the Brno University of Technology - Institute of Materials Science and Engineering.

Collection Service

We collect and deliver the customer's goods to be treated, as required.

Final quality inspection

We verify the quality after heat treatment of parts. We use hardness testers designed for all the basic hardness measurement methods, including our mobile hardness meter for the measuring of large and complex shape components. Our instruments are regularly verified.


The results of carried-out inspections are documented through quality certificates and other documents per the customer’s request (measurement protocol, hardness patterns, temperature diagrams, etc.)
