Appts. for plastic pipe prodn. - comprises injection head with nozzle unit and moulding unit having two matrix sections

摘要

An installation for producing plastic pipes of different dimensions, with laterally profiled walls, includes an injection head with a nozzle unit, a moulding unit with two matrix sections, and a series of mould channels. The mould unit has two channels, and the nozzle element is located at the injection head, so that it can rotate relative to the latter. The radical spacing between the nozzle element and the head longitudinal axis, half the axial spacing of the two mould channels. ADVANTAGE - The installation is simple and uses minimal energy.
