Procedure and means for manufacturing shaped articles containing cross-linked polyolefin from a mixture which contains 60-99% polyolefin, 0.01-10% chemically bound hydrolyzable silane and 0-5% condensing catalyst. The polyolefin mixture to be shaped contains 0.1-5% water and 0-20% water carrier agent, and that cooling the product subsequent to shaping is carried out under pressure. The means (20) comprises nozzle members (21) for pressing the shaped article of the polyolefin mixture, and members (22) for cooling the shaped article under pressure to a temperature which is below the boiling point of the water present in the mixture. The chamber (22) also includes means (24) for directing microwave radiation on the shaped article for releasing the water present in the form of crystal water in the polyolefin mixture. |
