The controller can be divided into 1-4 stages of injection and 1-3 stages of hold pressure. You can press F3 button F3-Function-techmation PLC controller injection molding machine to enter into the injection setting screen of your plastic molding machine.

Injection Pressure Setting Screen of Injection Molding Machines

Press Manual key Manual-operation-key-injection-molding-machine to enter into Manual mode. First, choose the Hold Pressure Transition mode Hold-Pressure-Transition-mode-Techmation-controller. Use the drop-down key drop-down-button-injection-machine-controlling-pannel to choose the Hold Pressure Transition including position/time/pressure. If the Time mode is used, the controller will switch into Hold Pressure after the set injection time had been reached. If the Position mode is used, the controller will switch into Hold Pressure after the preset end injection position had been reached. However, the set time is used as s backup to activate the Hold Pressure stage if sometimes the set transition position cannot be reached.

Notice: Your preset movement timing must be longer then the injection time in order to prevent the low flow which will caused a failure product. Every stages of hold pressure transfer according to the movement timing and it is not effected by the hold pressure transfer mode.

You can control injection and hold pressure by joining Time and Position mode together. If the end position of injection cannot be reached, change into Time control. Anyway, you can get more information about injection status from the Monitor 1 screen.

Now you can set the hydraulic pressure and speed for each of Injection and Hold Pressure stages, Enter the Positions setting for each injection stage and the time settings for each of the Hold Pressure stages.

Injection increase pressure functions: When you are using Accumulator, you can reach a fast injection pressure which is able to execute a high speed injection speed.

Injection fast set function: You may choose the execution of fast speed injection, choosing one more direction will reach a high speed injection.

Injection shut off:Use only when the machines has Shut Off equipment.

After set all parameters for Injection and Hold Pressure, please try to test all the presets under Manual mode Manual-mode-plastic-injection-molding-machines for optimum machine performance. If you encounter any problems during the operation, please press Manual key Manual-operation-key-injection-molding-machine to stop the machine from operating.
