What we do
The ideal supplier for the hot forging and extrusion of steel parts
Acsa | Steel forgings
From the moment of the offer, the design office supports the customer in the phases of developing the blank. Following the order, our engineers assess the customer's requirements and develop the product using the most recent and advanced design and mechanical processing technologies, as well as advanced systems to simulate the entire hot steel forging process.
A.C.S.A. Steel Forgings has its own mechanical workshop equipped with cutting-edge machining centers, lathes and EDM connected to the design office. The latter carries out all the processing phases via CAD/CAM, sending instructions to the CNCs of the various machine tools. Our mechanical workshop is fully involved in the production of the dies and equipment necessary for the production department to manufacture forgings.
The supplier of the raw material is carefully chosen by our team, consisting of the quality department and the purchasing and design department, following the standards and specifications received and approved by the customers.
A.C.S.A. Steel Forgings is equipped with a total of eleven production lines, with a nominal power of 1600 to 6300 metric tons. The lines are all mutually interchangeable to guarantee parts production for our customers. Each hot forging production line is composed of an electric induction heating furnace for the entire bar, with shearing at the pressing temperature (approximately 1250 degrees) controlled by an optical pyrometer that reads and guarantees the correct temperature at the core of the heated bar for each cut made. In addition, there is a first forging-slagging press, followed by the main press which performs the steel forging, a further press to simultaneously deburr and/or punch the part and finally a fourth press that performs the hot calibration function. In addition to this, more than half of our presses can be served by twist presses, which are essential for the production of twisted crankshafts. We are also equipped with three hot extrusion lines with capacities ranging from 400 to 1000 and 1250 metric tons; these also have electric induction heating furnaces and hot-pressing-temperature cutting. Finally, A.C.S.A. has two drop forging lines with a maximum power of 25,000 kg m for making parts not suitable for presses, due to higher volumes, weight or shape.
A.C.S.A. Steel Forgings checks forged steel production using an inspection team of specialized personnel and modern equipment, jigs and measuring tools. In addition, we have a constant temperature chamber housing a three-dimensional measuring machine for scanner and/or probe measurements.
This is where chemical, mechanical, metallographic, quantometric and hardness tests are carried out. The laboratory is organized according to the ISO/IEC 17025 standard and is equipped with modern, certified instruments and equipment to ensure compliance with the technical requirements of specifications received from customers. Our instruments includes an optical microscope, traction machine, spectrometer and quantometer, Charpy pendulum and Magnatest.
To ensure a result that respects the desired characteristics and details, all our products are supplied by scrupulously following every customer request.
We are equipped with seven shot blasting machines for slagging parts coming from hot forging and/or heat treatment. Visual inspection is always carried out by our specifically trained staff prior to packing. We also have two presses of 1,600 and 2,000 metric tons to carry out calibrations and/or cold coining in order to guarantee part parallelism. We also have three automatic HB durometers, to guarantee 100% hardness after heat treatment or BY. Finally, we are equipped with seven automatic and manual magnet particle inspection units for the quality control of safety parts. Each operator has a license and meets all the necessary regulatory requirements.
On the 5th May 2022 A.C.S.A. Steel Forgings inaugurated a new production line of 4,000 Tons. This is the eleventh line of production for Read more
