Press system (10, 11, 12, 13, 14) for production of partially expanded polymer bodies, comprising a mould cavity (20) of variable volume, temperature control means (30), counter 5 pressure means (40) arranged to counteract expansion of the mould cavity during moulding, wherein the pressure applied by the counter pressure means is arranged to increase in response to expansion of the mould cavity. There is also provided a method of moulding a partially expanded polymer body. |
