Injection moulding method for forming a bottle crate, bottle crate and corresponding apparatus for obtaining such bottle crate

摘要

The present inventions concerns an injection moulding method and corresponding apparatus for forming at least partially a bottle crate (20, 35) with molten plastic material including additive elements, comprising the step of injecting in a mould (3, 43) through at least one injection nozzle (6, 7 ; 59) said molten plastic to form at least partially a panel (2; 21, 22; 36, 37) of said bottle crate, wherein the molten plastic spreads in two opposite flows (4, 4', 4'', ... ; 5, 5', 5") toward each other until at least a visible junction area (10, 11 ; 53, 54) to provide an initial contact layer of molten plastic when said opposite flows meet each other. It comprises the step of canalising the flows at an extremity of said junction area towards an external overflow duct (16, 17 ; 55, 56) outside of the visible junction area, and filling said overflow duct with the molten plastic of said initial contact layer, for eliminating dark flow lines in said junction area.
