Haochen Hot Runner tells you:

1、 Check the pneumatic or hydraulic input and output pipelines, pumps, and valves for leaks and blockages, and check for damage to the sealing rings in the cylinder body and piston fitting.

2、 Check whether the valve sleeve and valve needle can fit flexibly and freely, and whether there are any issues with concentricity and roundness during self processing.

3、 Is there any inconsistency in the cylinder body, splitter plate, and hot nozzle gate, and is there an additional valve needle guide device added.
