Horizontal injection molding machine is an important equipment widely used for manufacturing plastic products, but in daily operation, it may encounter various failures. Understanding and mastering troubleshooting methods is essential to ensure the continuity and quality of production. Next, Liansheng Precision injection molding machine Xiao Bian will tell you about common faults of horizontal injection molding machine and provide corresponding troubleshooting methods. Let's have a look!

1. The injection molding machine cannot be started:

·Check whether the power connection is good.

·Make sure that the switches and buttons on the control panel are set correctly.

·Check the power supply of the main motor and controller.

2. Material leakage or nozzle blockage of injection molding machine:

·Clean or replace clogged nozzles.

·Check the connection between the mold and the injection system to ensure that the seal is intact.

·Adjust the injection pressure and speed of the injection molding machine.

3. Mold opening and closing problems:

·Check the lubrication system of the mold to ensure adequate lubrication.

·Check the sealing and clamping mechanism of the mold, and repair the damaged or loose parts.

4. Quality problems of plastic parts (such as bubbles or short materials):

·Adjust the injection parameters of the injection molding machine, including temperature, pressure and speed.

·Check the quality and humidity of plastic materials.

·Check the design of the mold, which may need to be modified to improve filling and cooling.

5. Electronic control system fault:

·Check the cables and connections of the control system, and repair the loose or damaged wires.

·Reset the controller parameters to ensure they are consistent with the process requirements.

·Update or replace the controller software to resolve possible software problems.

6. Cooling system problems:

·Check the flow and temperature of cooling water to ensure that they are within the normal range.

·Clean and maintain the cooling system to prevent clogging of water pipes or radiators.

7. Hydraulic system fault:

·Check the oil level and quality of the hydraulic oil to ensure that it meets the requirements.

·Check the hydraulic lines and connections and repair any leaks or damage.

·Clean and replace the hydraulic filter to keep the system clean.

8. Security issues:

·Ensure that all safety devices (such as grating, emergency stop button, etc.) work properly.

·Train operators and maintenance personnel to avoid failures caused by human errors.
