Abstract

Пресс (10, 11, 12, 13, 14) для производства частично расширяющихся полимерных объектов, содержащий полость (20) пресс-формы переменного объема, устройство (30) управления температурой, устройство (40) противодавления, размещенное для противодействия расширению полости пресс-формы в процессе прессования, где давление, создаваемое устройством противодавления, увеличивается в зависимости от расширения полости пресс-формы. Также предложен способ прессования частично расширяющихся полимерных объектов.Press (10, 11, 12, 13, 14) for the production of partially expanding polymer objects, containing a cavity (20) of a variable-volume mold, a temperature control device (30), a counter-pressure device (40), placed to counteract the expansion molds in the pressing process, where the pressure generated by the backpressure device increases depending on the expansion of the mold cavity. A method of pressing partially expanding polymer objects is also proposed.
