Extrusion blow molding machine common problem repair method

It is very common to encounter some production failures in the production process of plastic products. Today MEPER made a collection to summarize some common failure problems. How should we solve them? Let’s understand together.

1. The feeding tray is jammed. The problem of jamming during the feeding process may be because the length of the embryo is too long and the weight is large.

2. The feeding level is not enough for feeding. In this case, we need to carry out some inspections to check whether there is no material in the hopper, and add the amount in time. If it is not because of the feeding problem, we need to continue to check the power status and quickly check the motor. Whether it is in the power-on load state, adjust it in time, if not, check whether there are other problems in time.

3. The mold cannot be removed from the mold after blow molding. In this case, the mold should be resisted first, and the mold should be opened and closed manually, and run in an idling state. If everything is normal, you need to check the exhaust settings. If there is no problem, you need to identify whether it is the problem of the exhaust valve, open the exhaust valve to check the condition of the seal, if there is no problem, check whether there are screws in it, or because the clamping force is too large, if there is These issues are adjusted in a timely manner according to the standard.
