What is the reason the liquid silicone feeder can not shoot glue? How to solve it?

September 23, 2024
When the equipment fails, we should know where its cause is and what causes it to appear this phenomenon. The same is true of the liquid silicone feeder, so what is the treatment method that the liquid silicone machine can not shoot glue?
 
1. Liquid silicone feeder nozzle is clogged with dirty things. Check the nozzle for impenetrability. Clean or replace the nozzle.
 
2. Glue barrier. Remove the flange and check whether the nozzle is broken. Replace the glue nozzle.
 
3. The injection direction valve is stuck. Check whether the directional valve has 24V voltage and coil resistance of 15-20 ohms. Normally, the valve is blocked. Clean the valve or replace the directional valve.
 
4. The injection piston rod of liquid silicone machine is broken. Loosen the ejector piston rod and check whether the rod is broken. Replace the piston rod.
 
5. The barrel temperature is too low. Check whether the actual temperature reaches the melting point temperature required for the material. Then adjust the barrel temperature.
 
6. The sealing ring of the rubber injection piston is damaged. Check piston seal for damage. Replace the seal ring.
