Causes and Solutions of Unstable Cycle in Injection Molding Machine

Reason
1. Time to keep the mold open
2. Pressure instability
3. Barrel temperature is not consistent
4. Mold temperature inconsistency
5. Feed instability

Corresponding measures
1. Keep the mold open time:
Maintain fixed cycle times for varying lengths of time using a die opening timer

2. Pressure instability:
Maintain sufficient pressure to keep the discharge consistent
Check the pressure system for oil leaks

3. Barrel temperature is inconsistent:
Check the temperature control system to maintain normal operation
Use the best temperature control system
Check the voltage and stabilize it
Make sure the heater is working properly
Before material is added to the hopper, the temperature of each barrel of material should be maintained at the same level
The amount of material at the front end of the plunger should be maintained in a consistent manner
The machine should be maintained in a balanced condition

4. Mold temperature is inconsistent:
Using a mold temperature controller
There should be a proper channel in the mold
The mold should have a proper exhaust pipe
Usually the water pipe in the mold should have an appropriate connection

5. Unstable feeding:
Check feeding mechanism
