Oelheld U.S. Inc introduced AirForge 4500 this summer. Oelheld reports the product to be "a capable die lubricant with excellent separation and lubricating properties. The product is particularly suitable for and on applications where full flood lubrication is needed. On contact with hot surfaces, AirForge 4500 forms a film which controls the heat transfer between the tool and the work piece. The excellent solubility of the fluid guarantees reduced build-up on dies and presses and ensures clean castings." As background, Hatebur Hotmatic hotformers are suited for forging parts such as wheel spindles, gear blanks, bearing rings, and nuts which are produced from steel bars in a fully automa­ted process.
