<p>Plastics injection moulding machines have a screw carrying on its rear end a piston and at least one continuous flow channel extending to the screw cylinder, the pistons being guided in a corresponding piston cylinder and terminating in a sealing joint at the entrance to the flow channel for sealing the screw and piston cylinder. The liquid flow load and the injection pressure of the machine can be varied independently. The machine can be rapidly adjusted to a different injection pressure without having to dismantle the entire injection assembly.</p> |
