Abstract
A process in an injection moulding procedure where molten thermoplastic material (2') or molten metal (2'') is injected through a hot runner system (1) and an inlet nozzle (3). The inlet nozzle (3) includes a micro-porous cooling body (4). Channels (5) are provided for communicating a cooling agent from a supply source (6) to the cooling body (4). Molten material is allowed to flow through the hot runner system (1), the inlet nozzle (3) and into a mould cavity (8). The molten material begins to solidify, whereupon the cooling agent flows through the channels (5) and into the cooling body (4). The cooling body (4) hereby cools the molten material surrounded by the cooling body (4). The molten material thereby solidifies into a plug (10) which stops further communication of molten material through the inlet nozzle (3) while the material is allowed to solidify in the mould cavity (8). The mould (7) can thereafter be opened, the detail produced can be removed, and the procedure can be repeated.
