I&#8217;m a supplier of servo hydraulic vertical injection moulding machines, and I know how crucial it is to keep those sensors in top &#8211; notch condition. Today, I&#8217;m gonna walk you through exactly how to calibrate the sensors in a servo hydraulic vertical injection moulding machine. <a href=\"https:\/\/www.baizanplast.com\/hydraulic-vertical-injection-moulding-machine\/\">Servo Hydraulic Vertical Injection Moulding Machine<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.baizanplast.com\/uploads\/47357\/small\/handle-tool-overmoulding-machine20260402022436c967b.jpg\"><\/p>\n<p>First things first, let&#8217;s understand why sensor calibration is so important. These sensors play a key role in the precision and efficiency of the machine. They measure pressure, temperature, position, and other vital parameters. If they&#8217;re not calibrated correctly, you might end up with products that don&#8217;t meet the required specifications. That means wasted materials, more production time, and unhappy customers.<\/p>\n<h3>1. Before You Start the Calibration<\/h3>\n<p>Before diving into the calibration process, you need to do some prep work.<\/p>\n<ul>\n<li><strong>Safety First<\/strong>: Make sure the machine is turned off and disconnected from the power source. Working on an energized machine is extremely dangerous and could lead to serious injury.<\/li>\n<li><strong>Gather Tools<\/strong>: You&#8217;ll need basic tools like wrenches, screwdrivers, and, of course, a calibration kit. The calibration kit usually includes a pressure gauge, thermometer, and other measuring devices that are traceable to national or international standards.<\/li>\n<li><strong>Check the Machine Manual<\/strong>: Every machine is different, so it&#8217;s important to refer to the user manual for specific instructions on sensor calibration. The manual will also tell you the recommended calibration intervals.<\/li>\n<\/ul>\n<h3>2. Pressure Sensor Calibration<\/h3>\n<p>The pressure sensors in a servo hydraulic vertical injection moulding machine are responsible for measuring the hydraulic pressure. Incorrect pressure can lead to issues like incomplete filling of the mould or over &#8211; injection.<\/p>\n<ul>\n<li><strong>Isolate the Sensor<\/strong>: Use the shut &#8211; off valves to isolate the pressure sensor from the hydraulic system. This will prevent any sudden pressure changes during calibration.<\/li>\n<li><strong>Connect the Reference Gauge<\/strong>: Connect a calibrated reference pressure gauge to the same port as the sensor. The reference gauge should have a higher accuracy than the sensor being calibrated.<\/li>\n<li><strong>Zero the Sensors<\/strong>: Before taking any measurements, make sure both the sensor and the reference gauge are zeroed. This can usually be done by adjusting a small screw on the sensor or using the zero &#8211; setting function on the gauge.<\/li>\n<li><strong>Take Measurements<\/strong>: Gradually increase the pressure in the system using the hydraulic pump and take readings from both the sensor and the reference gauge at different pressure levels. Record these readings carefully.<\/li>\n<li><strong>Compare and Adjust<\/strong>: Compare the readings from the sensor with those from the reference gauge. If there are differences, you&#8217;ll need to adjust the sensor. Most pressure sensors have an adjustment potentiometer that you can turn to increase or decrease the output signal. Keep adjusting until the readings match within an acceptable range.<\/li>\n<\/ul>\n<h3>3. Temperature Sensor Calibration<\/h3>\n<p>Temperature control is critical in the injection moulding process. Incorrect temperatures can cause issues like poor material flow, warping of the final product, or even damage to the mould.<\/p>\n<ul>\n<li><strong>Disconnect the Sensor<\/strong>: First, disconnect the temperature sensor from the machine&#8217;s control system. This will prevent any electrical interference during calibration.<\/li>\n<li><strong>Use a Calibrated Thermometer<\/strong>: Place a calibrated thermometer in the same location as the temperature sensor. The thermometer should be in direct contact with the material or surface being measured.<\/li>\n<li><strong>Heat up or Cool Down<\/strong>: Heat up or cool down the material or surface to different temperature points. Take readings from both the sensor and the thermometer at each point.<\/li>\n<li><strong>Make Adjustments<\/strong>: If there are deviations between the sensor readings and the thermometer readings, you&#8217;ll need to adjust the sensor. Some temperature sensors can be adjusted electronically, while others may require replacing internal components.<\/li>\n<\/ul>\n<h3>4. Position Sensor Calibration<\/h3>\n<p>Position sensors are used to measure the position of the clamping unit and the injection unit. Accurate position measurement ensures that the mould is properly closed and the correct amount of material is injected.<\/p>\n<ul>\n<li><strong>Check Mechanical Installation<\/strong>: Before calibration, make sure the position sensor is properly installed and aligned. Any misalignment can lead to inaccurate readings.<\/li>\n<li><strong>Set the Reference Position<\/strong>: Determine the reference position for the sensor. This could be the fully open or fully closed position of the clamping unit or injection unit.<\/li>\n<li><strong>Measure and Compare<\/strong>: Use a precision measuring tool, such as a micrometer or a laser distance meter, to measure the actual position. Compare this measurement with the reading from the position sensor.<\/li>\n<li><strong>Adjust the Sensor<\/strong>: If there are differences, adjust the position sensor. Some sensors can be adjusted by changing the mounting position or by using the calibration settings in the machine&#8217;s control system.<\/li>\n<\/ul>\n<h3>5. After Calibration<\/h3>\n<p><img decoding=\"async\" src=\"https:\/\/www.baizanplast.com\/uploads\/47357\/small\/two-station-vertical-injection-moulding57b2b.jpg\"><\/p>\n<p>Once you&#8217;ve completed the calibration of all the sensors, there are a few more steps to take.<\/p>\n<ul>\n<li><strong>Reconnect the Sensors<\/strong>: Make sure all the sensors are properly re &#8211; connected to the machine&#8217;s control system.<\/li>\n<li><strong>Run a Test Cycle<\/strong>: Start the machine and run a test cycle. Observe the performance of the machine and check the readings from the sensors. Make sure everything is working as expected.<\/li>\n<li><strong>Document the Calibration<\/strong>: Keep a record of the calibration process, including the date, the readings taken, the adjustments made, and the results of the test cycle. This documentation is important for quality control and for future reference.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/www.baizanplast.com\/vertical-injection-molding-machine\/tiebarless-injection-moulding-machine\/\">Tiebarless Injection Moulding Machine<\/a> Now that you know how to calibrate the sensors in a servo hydraulic vertical injection moulding machine, you&#8217;re well on your way to ensuring the best performance of your machine.
