Yuav ua li cas kho qhov Sensor Position nyob rau hauv ib tug kub khiav

Txhawm rau txo qis kev sib txhuam ntawm cov cua sov cuam tshuam thiab nce qhov ntsuas kub kom raug, qhov ntsuas qhov ntsuas kub yuav tsum tau hloov kho los ntawm kev zam kom tsis txhob siab -shear aav, ua kom qhov deb ntawm 10–20 mm los ntawm lub rhaub, thiab lav qhov ruaj khov thiab sib luag . 1. Kev Hloov Kho Cov Ntsiab Lus ntawm qhov siab {{1} Stearsher installation} ntawm qhov nqaim khiav inlet (<2mm), flow divider cone, or nozzle tip. Because of the high-speed melt flow, these regions produce a lot of frictional heat, which causes temperature readings to be off. Select a Location with Good Temperature Representativeness: It is advised to install in the hot runner connection area or the central section of the main runner. In this case, there is little local interference, a consistent temperature distribution, and stable melt flow. Keep a Reasonable Thermal Coupling Distance: To prevent conduction overheating or reaction latency, keep a distance of 15 mm ± 5 mm from the heater center. Practical Value: In a medical catheter mold, the product yield increased by 12% and the temperature variation dropped from ±6°C to ±1.8°C after the sensor was moved from the nozzle tip to the central region of the main runner. 2. Crucial Elements of Multi-Cavity System Modification Symmetrical Arrangement: To avoid uneven filling as a result of temperature measurement errors, each channel sensor's installation depth, angle, and distance from the heater must be constant. Use Positioning Fixtures: To guaranty consistent installation locations every time and minimize human mistake, use specialized fixtures or templates. Reserve Debugging Holes: To make it easier to compare data performance at various areas during trial molding, many temperature measurement holes can be set aside at first installation. Note: Strict management is necessary because asymmetrical layout is a major cause of multi-cavity imbalance. 3. Steps for Installation and Verification After shutting down and cooling, make sure the hot runner is fully cooled to prevent burns or component damage. Clean mounting holes: To guaranty effective heat conduction, remove carbon residues and deposits. Apply thermal grease: To minimize temperature measurement lag, apply a tiny bit of high-temperature thermal lubricant between the sensor and the hole wall. Tighten to torque requirements: To keep the fastening nut from loosening, tighten it with a torque wrench. Record position parameters: For simple traceability, make a record that includes angle, depth, and distance. Safety Principles: The four procedures of "avoiding hot spots + maintaining spacing + symmetrical placement + data verification" must be followed in order to accomplish reliable temperature control.
