1): Mechanical level and parallelism are out of tolerance. Check with a spirit level angle ruler. Adjust the parallelism and level. (For large models, small models have little effect)
2): The gap between the pressure plate and the die-adjusting nut is too small. Measure with feeler gauge. Adjust the gap between the pressure plate and the nut, and adjust the gap between the die nut and the pressure plate (clearance ≤ 0.05mm).
3): Burning the nut: Check whether the nut can be turned to generate heat and iron powder is coming out. Replace the nut.
4): Adjust the upper and lower support plates. Remove the lock nut of the expense board to check. Adjust the adjusting nut.
5): The I/O board is broken. Check whether there is a signal at the output point on the computer page. Repair the electronic board.
6): The mold adjustment spool is stuck. Remove the valve and check. Clean the valve.
7): Die adjustment motor is broken: check the oil motor. Replace or repair the oil motor.
