Solutions for Clamping Faults in PET Injection Molding Machines

Solutions for Clamping Faults in PET Injection Molding Machines!

The Clamping section of a PET injection molding machine is a vital component, and encountering issues in this section can render the entire machine inoperable, resulting in subpar production quality. Drawing upon years of experience in the PET injection molding machine industry, we have analyzed common issues in the Clamping section and provided corresponding solutions.

Firstly, let's address situations where the PET injection molding machine fails to perform Clamping. To tackle this issue, we propose the following solutions. Start by inspecting the forward travel switch of the safety door and carrying out any necessary repairs. Next, check the 24V5A power supply in the control cabinet and replace the fuse box and power supply unit if needed. Additionally, examine if the valve core is stuck, and clean it promptly if any issues arise. Ensure that the I/O board has output signals to guarantee proper energization of the solenoid valves. Lastly, verify whether the hydraulic safety switch is correctly engaged and if the mechanical locking bar plate is in the open position.

Next, let's examine situations where the PET injection molding machine generates noise during the mold opening and closing process. To address this, we offer the following solutions. Check whether the lubrication oil pipes are loose and reconnect them securely if any issues are detected. Confirm that the lubrication oil level is sufficient, and increase the supply if it is insufficient. We recommend adding lubrication oil every 50 mold cycles. Then, assess whether the Clamping force is excessive and adjust it accordingly. Review the current parameters of the amplification board, ensuring compliance with acceptance standards and making adjustments as necessary. Lastly, employ a dial indicator to check if the parallelism of the mold exceeds the acceptance range. If issues are identified, adjust accordingly.

Handling Clamping faults in the PET injection molding machine is crucial as it directly impacts its proper functioning and the quality of the manufactured products. By implementing the aforementioned solutions, you can swiftly and effectively address common Clamping faults and ensure the stable operation of your PET injection molding machine.
