There is one thing we should understand about injection moulding machine, the various voltages for specific functions are switched in by a relay in the PCB that is controlled by the switches in the switch pad. If for any reason the switches are not coming on, there is a problem with the control voltage cct in the PCB or the relay may be bad.

If the relay is latching and the expected power is not delivered, there is a problem with the power cct of the pcb. Tracing the power cct is simple since the power supply is usually involved, but that of the relay control is some how difficult.

In most cases resistors and capacitors in the power cct are usually affected by flash or corona that occurs in an unearthed system or improper earthed system.

If there no physical cause, U should be looking at the ICs in the cct board.

Also check ur electro mechanical contactors.
