摘要： In a sawing cord the three constituting elements of steel cord, sawing bead and sleeve polymer in between the beads must work optimally together. In order to improve the injection moulding quality the inventors disclose an injection mould wherein the injection channels inject polymer from opposite sides of the steel cord into the injection cavity. The injection mould comprises two half moulds that form the injection cavity when closed. Different preferred embodiments are described inclusive the use of channels having a tree structure, preferably a binary channel tree, preferably a balanced binary tree and most preferred a balanced binary tree with equal length pathways from feed channel to each injection channel. The use of heated channels is disclosed and the rules for balancing between the number of heated versus non-heated channels are explained. Furthermore the method to use such mould and the product resulting from the use of the mould are claimed.
