Plastic injection molding machine is one of the key equipment for manufacturing plastic products. Its performance and life directly affect production efficiency and product quality. In order to ensure the normal operation of the injection molding machine and extend its service life, maintenance and care are essential. The following are the key steps for the maintenance of plastic injection molding machines: today Injection molding machine manufacturer -Liansheng Precision will talk about the key steps of the maintenance of the plastic injection molding machine.

1. Clean and keep dry:

Keeping the injection molding machine clean and dry is the primary task of maintenance. Regularly remove the dust, dirt and residues inside and outside the injection molding machine. Ensure the drying of plastic raw materials to avoid adverse effects of humidity on production.

2. Lubrication system maintenance:

Regularly check and maintain the lubrication system, including the lubrication points of injection unit, mold part and mechanical transmission system. Use proper lubricant to ensure smooth operation of all parts.

3. Check the electrical system:

Regularly check the electrical system, including the control panel, cables, sensors and switches. Ensure that the electrical connections are secure and free from damage or wear.

4. Temperature control system:

Monitor and calibrate the temperature control system to ensure that the plastic material maintains a constant temperature during injection. Check heating elements and sensors regularly.

5. Injection unit maintenance:

Check the status of injection unit, including screw, cylinder, nozzle and mold. Make sure they are not damaged or worn, and clean and maintain them regularly.

6. Mold maintenance:

Mold is a key component of plastic injection molding machine, and it shall be inspected and maintained regularly, including cleaning, lubrication and replacement of worn parts. Ensure that the mold is in good condition to obtain high-quality products.

7. Safety system inspection:

Regularly check the safety system of the injection molding machine to ensure their normal operation. This includes door locks, emergency stop switches, safety barriers, alarm systems, etc.

8. Operation parameter monitoring:

Regularly monitor the operating parameters of the injection molding machine, such as injection speed, pressure, temperature and cooling time. Adjust as necessary to ensure that the product meets the specifications.

9. Component replacement:

Regularly replace consumable parts, such as nozzles, screws, heating elements and sealing rings. Timely replacement of these parts can prevent production interruption and quality problems.

10. Training and operation procedures:

Ensure that operators are trained to understand the correct operating procedures and maintenance points. Establish operation manual and maintenance log to record maintenance activities and problems.

11. Regular maintenance plan:

Develop a regular maintenance plan, including a schedule for cleaning, lubricating, inspecting, and replacing components. Follow the plan to carry out maintenance work to avoid sudden failure and production interruption.

12. Periodic inspection and adjustment:

Carry out comprehensive inspection and adjustment regularly to ensure that the injection molding machine is in good working condition. This includes checking the tension of fasteners of mechanical parts and transmission system.

Maintenance is to ensure Plastic injection molding machine Key factors for long and efficient operation. Regular maintenance can reduce failures and production downtime, improve product quality, reduce maintenance costs, and extend the service life of the injection molding machine. Therefore, it is very important to develop maintenance plans, train operators and regularly monitor the status of equipment. These steps will help ensure the stable and reliable operation of the injection molding machine in production.
