摘要：
A balanced runner system for injection moulding apparatus is disclosed. The runner system has an inlet, a plurality of runners and five gates. One of the gates is centrally located, the remaining gates being symmetrically spaced about the centrally located gate. The runners are such that the runner system is capable of supplying molten polymer to each gate at substantially the same rate. The runner system may be used to obtain a more uniform flow of molten polymer to a mould.
