HOT PRESS METHOD AND DEVICE

摘要

The invention relates to a hot press method characterized in that a punch has a plurality of pressurization shafts with respect to the pressurization shaft (1) of the ram of a hot press and in that pressing is effected with graphite in sheet form interposed between the ram and punch. The invention provides a hot press method and device, that incorporate the advantages that a plurality of hot press products can be simultaneously produced, that forming is possible in a shape substantially resembling the shape of the product and that the yield is improved as compared with a single-shaft hot press device, and that is designed to impose load evenly on the punch to uniformize and improve the quality of products and to prevent damage to the device, etc.
