(1) Hot runner mold because of the increase of hot runner, more runner plate, so the thickness of the mold increases accordingly, choose the injection molding machine to pay attention to the installation height of the injection molding machine.
(2) when the injection volume of injection molding machine is measured, the compressibility of plastic in large volume flow channel should be taken into account.
(3) For the depreciation of hot runner mold, continuous operation of injection molding machine is advocated, and multi-stage start-up is used to reduce damage.
Many devices are used to ensure the automatic operation of the mold. The first choice is a robot or a simple and controllable manipulator, such as:
(1) products need to insert inserts, labels or flakes to wait for the mold.
(2) remove plastic parts or accelerate their ejection.
(3) control the movement of plastic parts and reduce the starting time annexes.
(4) heating the mold before starting the injection molding machine.
(5) Reduce the time of the mold, reduce the connection time of the cooling water pipe, the air path, the circuit and the hot runner temperature control box.
