Forging is carried out with presses or hammers and during this process the heated material fills in a cavity of the tool – a die. This technology is apt for production of larger series. The advantage of closed-die forging is repeated dimensional accuracy, less additions for metal machining and a higher grade of forging.The forging parts can be calibrated in order to achieve more precise dimensions and to reduce the necessity of further machining.
Open-die forging is carried out with power hammers or with hydraulic presses at dimensionally simplier forgings. Fitted shafts, bars, rings, flanges etc. should be mentioned as the main types of these forgings . This sort of forgings is also appropriate for a one-piece work as there are no costs of the die production. As for disadvantages, there is a need to choose bigger material additions for the final machining.
We can deliver both hand-formed or machine-formed castings in terms of the single piece production as well as the medium series production. Castings can be delivered including finished machining or rough machining.
We are able to get ready the medium size series of forgings and castings including all the machining based on a customer´s technical drawing. Machining is carried out either with standard machines or in some special CNC machining centres.
Besides the usual ways of machining we can offer you:
Screw-thread rolling to M27
Gearing production up to module 6 mm and with a diameter of the head circle up to 300 mm
