TECHMATION Controller Operation Manual-Injection molding Machine

This article is a step by step instruction of how to set the heater parameters of injection molding machines running Tecmachine PLC controller. Include the details of heater setting process & specifications for your study. Press the Manual key to activate the Manual mode . Switch the HMI display to the Temperature setting screen by pressing F8(Temperature). There are maximum 6 zones barrel heating zones to be controlled as the plastic injection machine’s specifications. The temperature can be controlled separately for each zone of barrel heating. The current and preset temperature for each barrel heating zone will be displayed in the right side of screen. Heater Temperature Setting Screen of Injection Molding Machines First, set the Temperature Mode(Half Warm): Choose “Not neccessary” if you want to keep the

Press the Manual key to activate the Manual mode . Switch the HMI display to the Charge setting screen by pressing F4(Charge) on the controller panel of your plastic molding machine. Charge (Plasticizing) is divided into 3 stages. You can set the speed and pressure separately. If it is necessary, you can also execute the suck-back after the charge. Press the manual key and ensure it is under the manual mode. Please press the F2(Charge) on the panel to enter the charging screen .Next, insert the position to transfer the 3 stages charging movement. Charging (plasticizing) and suck-back Setting screen If there is a control back pressure with the setting value of pressure function, you can set the back pressure in order to raise the density of the plastic

The controller can be divided into 1-4 stages of injection and 1-3 stages of hold pressure. You can press F3 button to enter into the injection setting screen of your plastic molding machine. Injection Pressure Setting Screen of Injection Molding Machines Press Manual key to enter into Manual mode. First, choose the Hold Pressure Transition mode . Use the drop-down key 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

Nozzle Unit Setting depends on your requirements you can set up the nozzle/injection unit to retract after injection has finished. The controller offers you 3 different modes to choose from if nozzle/injection unit retraction is needed. Nozzle Settings Process of Plastic Injection Molding Machine Press manual key   on the controller panel of plastic injection molder，to activate the Manual operation mode. Switch the HMI display to the Nozzle setting screen by pressing F7(Nozzle). Nozzle Setting Screen of Injection Molding Machine First step please click to set the nozzle retraction mode, After Charge mode: retract the nozzle /Injection unit after charge (plasticizing) is finished. Before Mold Opening mode: retract the nozzle /Injection unit before mold opening start. After Injection mode: retract the nozzle /injection unit after injection has finished.

Cores Setting Instruction of Injection Molding Machines running Techmation PLC controller Press the Manual key to activate the Manual mode . Switch the HMI display to the Core setting screen by pressing F6  (Cores). Injection Molding Machine Core Setting Process Injection Molding Machine Core Setting Screen Depending on your setup your plastic injection machine may be equipped with up to 3 cores (A, B and C). Each core is controlled separately. Warning: When setting up the core(s), you need pay close attention to make sure the settings will not cause damage to the core(s) and/or the plastic injection mold. Since the cores are freely programmable it is impossible for the controller to prevent all possible settings errors. First, choose up arrow or down arrow to select the ABC

The plastic injection machine provides an air blast ejection option for the moving platen(the moving platen) as well as for the stationary platen(the fixed platen) Press the Manual key to activate the Manual mode. Switch the HMI display to the Ejection setting screen by pressing F5 (Ejector) . Set the duration of air blast for each platen Set the plastic mold opening position at which you want to activate the air blast. If required, please set the Delay Time to activate the air blast. After setting all parameters for air blast, please try to test all the presetting under Manual mode to check for optimum machine performance, if you encounter any problems during the operation, please press Manual key  to stop the machine from operating.

The ejector settings can be operated in three different modes to knock the finished product out of the mold at the end of mold opening. You can choose between the Hold, Count Number and the Vibration modes. Warning: Hold mode can be used only in semi-automatic operation. Hold Mode：The ejector moves forward according to the ejector settings and the product is dropped or taken out. After the safety gate has been opened and closed the next cycle will start.   Count Number mode: The ejector is activated according to the Ejector and Ejection Cound settings. This mode is usually used for automatic machine operation. It does not require the opening and closing of the safety door to continue the production cycle.   Vibration mode:The ejector movement is controlled by

Mold closing is executed in four phases: Mold Opening Stage 1, Mold Openning Stage 2, Mold Open Stage 3, and Mold Open Stage 4. Press the Manual key to activate the Manual mode. Switch the HMI display to the Clamp Setting screen by pressing F2 (Clamp) . Then, enter the desired hydraulic speed and pressure setting for the 4 mold opening stages. You have to ensure that those settings allow for a smooth, jerk-free movement of the plastic injection mold. Set the hydraulic speed for the Mold Opening Stage 1 in order to separate the mold platen smoothly. Adjust the transition point for switching from Mold Openning Stage 1 to Mold Opening Stage 2 according to your requirement. The transition point setting of switching from Mold Open Stage 3

There are 5 stages of pressure & speed controlled for mold closing: Mold Close Stage 1, Mold Close Stage 2, Low Pressure Mold Protection and High Pressure.For optimum productivity mold closing should be excecuted as fast as possible. However, it is important to preset correct data to ensure the protection of the plastic injection molds. For this reason pay particular attention to the Low Pressure Close mold part. Press the Manual key to activate the Manual mode . Switch the HMI display to the Clamp Setting screen by pressing F2  mold platen key. Check and set the Max. Mold opening stroke and ensure that it will not exceed this stroke. Next, enter the desired speed and pressure for the 4 stages of mold closing. You have to ensure
