Machine Start-up

There are two basic modes of machine operation.

1- Setup:  This includes manual operations. In this mode, every press action requires manual pushing of an appropriate button to bring about the desired action.

2-  Semi-Auto or Full-Auto: In automatic operation timers, relays, and limit switches are electrically coordinated to produce the proper sequence of operations, so that each cycle is repeated from shot to shot, and the end result is a finished product with consistent characteristics.

No buttons should be actuated if the machine is in a shut-down condition. In that case, the first move should be to open the water lines to all connections, such as the heat exchanger, the hopper throat, and any other component requiring water coolant. Next one should make sure that all pump suction valves are open.

One shoud check the setup record, which indicated not only the set of parameters for the job but also the accessoroes needed.

Having assembled all the items needed for mold mounting and setup, one can proceed to manipulate the machine.

Before any model is selected, power has to be available in the control
