Keep good operation habits to ensure the safe operation of plastic processing equipment

Plastic processing equipment is a kind of equipment for plastic molding, and it’s very common in the plastic processing industry. The operation of plastic processing equipment is not difficult, actually in general is relatively simple. But even so, also hope that we can form a good habit operation, so it is good for the subsequent use of plastic processing equipment, and improve the service life of the equipment.

First, before the boot

1. Check whether there is water and oil in the electrical control box of the plastic processing equipment. If the plastic processing equipment is damp, do not start it. Electrical parts should be blown dry by maintenance personnel before starting.

2, Check whether the supply voltage is consistent, generally should not exceed ±15%.

3, Check the emergency stop switch, before and after the safety door switch is normal. Verify that the rotation direction of motor and oil pump is consistent.

4. Check whether the cooling pipes are unimpeded, and put cooling water into the Oil cooler and cooling water jacket at the end of the barrel.

5. Check whether there is lubricating oil (grease) in each moving part, and add enough lubricating oil.

6. Turn on the electric heat to heat each section of the barrel of the plastic processing equipment. When the temperature of each section reaches the requirement, keep warm for a period of time to make the temperature of the machine tend to be stable. The insulation time varies according to the requirements of different equipment and plastic materials.

7, Add enough plastic material in the hopper. According to the different requirements of injection molding, some raw materials better through dry first.

8,To cover the heat insulation cover on the barrel, which not only can save energy, but also can extend the life of electric heating coil and current contactor.

Second, the operation process

1. Do not cancel the role of the safety door for convenience.

2. Pay attention to the temperature of the pressure oil, and the oil temperature shall not exceed the specified range. The ideal working temperature of hydraulic oil should be kept between 45 ℃ and 50℃, generally in the range of 35 ℃ to 60℃ is more appropriate.

3, pay attention to adjust the travel limit switch, to avoid plastic processing equipment in the action of the impact.

At the end of the work

1. Before shutdown of plastic processing equipment, the plastic in the barrel should be cleaned up to prevent oxidation or long-term thermal decomposition of the residual material.

2, the mold should be opened, to ensure the elbow bar mechanism in a locked state for a long time.

3.The plastic processing equipment workshop shall be equipped with lifting equipment. When assembling and disassembling molds and other heavy parts, we should be very careful to ensure production safety.

Above is the introduction of the relevant content of plastic processing equipment that we explain to you. I believe that after reading this article, you have a new knowledge and understanding of the processing equipment. I hope our introduction can bring you certain assistance.
