Heat treatments

Services provided

Stress relief annealing for welded assemblies and castings, temperature mounting, as well as annealing for improving machinability and cast iron ferritization

• Normalizing
• Solution quenching and artificial ageing for aluminium parts
• Quenching + Tempering

Thermochemical Heat Treatments

We execute Carburizing and Nitriding Treatments

For carburizing, nitriding, carbonitring and nitrocarburizing we employ proprietary homologated technologies using a gas mixture that differs according to requirements: methane gas, propane, ammonia, nitrogen, endothermic gas and CO₂.

• Thermochemical Heat Treatments operations
• For special steel parts we execute controlled atmosphere quenching to ensure minimal deformations and superior product quality

Induction Hardening

We execute induction hardening

Our equipment has automatic converters which allow saving the parameters , therefore providing a high degree of repetability

• We can assure case depth from 2.5 to 6.0 mm on equipment of 8KHz and 0.6 – 2.4 mm on equipment of 100KHz
• We perform services for customers such as: Neptun, Softronic, Menarom, Stentor Maritime Steel Constructions, Pronif, Promex, Upetrolam, Popeci, Reșița Reductoare & Regenerabile, Tehnomet, Prompt, Arsat, Emsil

Galvanic Coatings

Galvanic Coatings list of operations

• Black Oxide Coating for Rings and rollers made by Timken, Rulmentul Barlad and INA Schaeffler
• Manganese fosphating to bear-rings shafts for Ina Schaeffler

Press Quenching

Klingelnberg quenching press

The possibility of performing press quenching on a Klingelnberg press for products susceptible to deformation or requiring strict control of their execution dimensions.

• reduction of the effort and time for final grinding
• suitable for gears
• bevel gears, rings and other types of parts

Machining

Machining on CNC machines, milling and grinding.

On equipment with numerical command we can machine parts with the maximum dimensions of: D = 250mm, L = 450 mm

• Plane grinding for parts with maximum dimensions of 300 x 1000 mm
• Shaft grinding for parts with maximum dimensions of D = 300 mm and L = 2000 mm
• Threading by pressing
• Grinding of shafts that were hard chrome plated
• Milling
