FIELD: mechanics.
SUBSTANCE: press mould includes a die and a punch. The latter is made so that it can penetrate into the die cavity for forming the moulding chamber of press mould. Item is formed by inserting the punch under pressure into the die cavity, in which the body made from polymeric material and measured beforehand was placed and the weight of which is measured according to reference value. Die includes at least one deformable wall the inner surface of which comprises at least some part of the die surface. At that, the above deformable wall has at least partially the thickness which is relatively small, which allows it to be elastically deformed under pressure of polymeric material at the final item forming stage, thus, compensating the error of the measured body weight in relation to reference value.
EFFECT: possibility of specifying the error of measurement compensation, and more effective and quicker removal of heat generated during the pressing process.
