EspañolThe choice of injection molding machine is also very important when the mold of hot runner is designed and manufactured.All automatic circulation capabilities of injection molding machine shall be applicable to hot runner system.The following factors should be considered when choosing injection molding machine:
1) due to the increase of hot runner channel and the increase of block runner plate, the mold thickness increases accordingly. When choosing the injection molding machine, pay attention to the installation height of the injection molding machine.
2) the compression of plastics in the large volume flow passage should be taken into account when measuring the injection volume of the injection molding machine.3) for the depreciation of hot runner mould, the continuous operation of injection molding machine is advocated, and multi-stage start is used to reduce the bad hunting.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) the product needs to be inserted into the insert, label or slice to wait in the mold.2) remove the plastic pieces or accelerate them to pop out.
3) control the movement of the plastic parts and reduce the start time attachment.
4) heat the mold before starting the injection molding machine.
5) reduce the time of upper mold, reduce the connection time of cooling water pipe, air path, circuit and temperature control box of heat flow channel.
