Solve semi-automatic non-injection action needs to analyze the possible causes and take corresponding measures for investigation and repair.
The advancement of the injection unitis not terminated.
Check whether the injection unit and themold clamping limit switchare normal.
Meanwhile,check the electrical wire connection of the valve.
Reset the linear displacement sensor of the clamping unit.
When the machine clamping toggle is straight, the position should be 0, readjust the zero position of the linear displacement sensor.

Check the status of the safety door
In semi-automatic mode, if the safety door is opened, the injection molding machine will stop quickly.
Confirm the control conditions
Before starting the semi-automatic mode, including mould opening in place, thimble back in place, screw back in place.
Motor power on, electric heating power on, and the temperature reaching set point, motor stationary state, and safety gate closed.
Check the electrical and hydraulic system
According to the specific stage of the failure of the semi-automatic action in the mechanical cycle, find out the corresponding control elements.
Adjust the pre-molding and injection time
If the injection volume is insufficient in semi-automatic mode,
The injection volume can be increased by adjusting the pre-molding time and delay time.
This is done by allocating a portion of the injection time to the pre-molding,
Where a portion of the material is injected into the mould through the back pressure of the pre-plastic and then transferred to injection.
Manual adjustment
In semi-automatic mode, if the ejector pin does not retract into place,
The program is designed with protective measures,
If it is not in place, the ejection action will be carried out first,
And then the subsequent clamping or ferrule action will be carried out.
Troubleshooting
If you encounter the problem of thimble loss of control in semi-automatic mode,
You can check whether the ejector pin board.
Program settings
Make sure that the program is set up correctly,
Especially in semi-automatic mode, and do not open the safety door before the injection action is carried out.
What is semi-automatic non-injection action?
The semi-automatic non-injection mode of the injection molding machine usually refers to the semi-automatic operation state.
The machine can automatically complete a molding cycle but does not perform the injection action.
In this mode, the machine starts with mould clamping.
Goes through pre-molding, cooling, mould opening, etc., but does not carry out the actual injection process.
At the end of each production cycle, the operator needs to manually open the safety door to remove the workpiece.
And then close the safety door again before the machine can continue with the next cycle of production.
In semi-automatic mode, the machine can automate most of the molding cycle actions.
Such as mould clamping, pre-molding, cooling, and mould opening,
But the injection actions need to be done manually or automatically by the machine under certain conditions.
For example, in some semi-automatic modes, the machine will automatically close the mould after the pre-molding is in place.
And then pre-mould and cool, but it may be necessary to manually operate or inject material.
Haichen’s operating specifications
In the semi-automatic non-injection mode of an injection molding machine.
Ensuring the safety of the operator requires a series of strict safety norms and measures to be followed.
First and foremost, all Haichen operators must be fully trained and familiar with local regulations and norms.
When operating the equipment, avoid wearing long hair.
Loose clothing, or jewelry to prevent it from getting caught in the equipment.
During the clean-up process, operators should wear heat-resistant PPE to prevent burns from contact with hot surfaces or splashing of hot materials and gases.
The material removed from the machine can be very hot.
And personal protective equipment needs to be worn as well.
All operators should wear personal protective equipment when working around the inlet and when cleaning machines or mould gates.
