Hot runner preform mould easy processing, easy maintenance

Hot Runner Preform Mould design after the need to put into the injection molding machine production, the choice of the injection molding machine is also very important. The entire automatic circulation capacity of the injection molding machine should be applied to the hot runner system. In the choice of an injection molding machine, the following factors need to be considered:

(1) Hot Runner Preform Mould due to the increase in the hot runner, more than a block flow path board, so the corresponding increase in the thickness of the mold, select the injection molding machine to pay attention to the installation height of the injection molding machine.

(2) Injection molding machine injection volume measurement, to take into account the large volume of flow in the plastic compression.

(3)For the Hot Runner Preform Mould depreciation, to promote continuous operation of the injection molding machine, with multi-level start to reduce the bad.

Many of the equipment used to ensure the automatic operation of the mold, a preferred robot or a simple and controllable manipulator, such as:

(1) The product needs to be placed in the mold, labeled, or sheeted to the mold.

(2) Remove the plastic parts or speed them out.

(3) Control the movement of plastic parts and reduce the start-up time of accessories.

(4) Before starting the injection molding machine to heat the mold.

(5)To reduce the time on the mold, reduce the cooling water pipes, gas, circuit, and hot runner temperature control box connection time.

The split plate is also called a hot runner manifold. It is the central part of the hot runner system, it will be the main channel nozzle for the plastic melt through the flow channel to the injection point nozzle. The manifold can fill the mold cavity evenly, balance the plastic flow, the system's heat balance. Shunt plate series X type, H type, I type, Y type, K type, other, and so on.

Hot runner manifolds are heated in two ways, one is to heat, that is, set the heating rod in the runner, from the flow inside the heating plastic. The other is the external heating, usually in the direction parallel to the flow channel, to set the heating hole, insert the heating rod, or install the heating ring, from the flow channel outside the heating channel.

In both cases, the internal heating method has a higher thermal efficiency, but it is likely to cause local overheating in the hot runner system and increase the melt flow resistance. Although the external heating method does not produce local overheating and flow resistance Small, easy to run the flow channel, the heating device is easy to buy, easy to maintain, but the heating efficiency is low.
