    The Multiforge is a unique concept with distinct advantage over conventional hot upsetting forging machines.

    One of its main features is the departure from conventional vertical opposed gripping dies and the innovation of the horizontal disposition.

    This greatly reduces operator fatigue as the weight of the forging is supported by the bottom die.

    Not only is the weight eliminated but in addition the operator is working at a constant height. Without the need to raise and lower the component between die impressions, as the case on conventional vertical grip die machines.

    The generous die width enables five forging stations to be set up in one tool assembly which can often eliminate secondary processing of certain components which require multiple operations.

    Die life is also improved by minimising the contact time between dies and hot metal of the work piece.

    These important features coupled with the fast stroking rate of the machine ensures a high production rate and competitively priced component.
