INDUSTRIAL STRAIN AND FORCE SENSORS SENSORS FOR MOLDERS Injection molding machines are no longer manufactured without sensors. The reason is simple: ever increasing demands for improved performance and consistent product quality call for fast and reliable machines with sophisticated controls. Sensormate products provide this control and help to achieve continuously higher quality levels. Sensormate prides itself on delivering products which offer maximum ease-of-use, making the job for the molder as simple as possible. ALL THE SENSORS YOU NEED FROM ONE MANUFACTURER That’s why over 80% of...

APPLICATIONS ALL-ELECTRIC INJECTION (and not only) > njection force: I - Wireless range of load cell for highly accurate monitoring of injection pressure, measuring axial force ant torque (optional); optimum location behind the screw. - Diaphragm load cell: the flat-body design allows for easy integration into the Injection unit. > old protection (also in Hydraulic/Hybrid Injection molding M machine): - Our strain sensors detect parts between mold halves instantly. > ocking force (also in Hydraulic/Hybrid Injection molding L machine): - Strain sensors (SB,SL) measure the deformation on the...

INDUSTRIAL STRAIN AND FORCE SENSORS The structural integrity of the molding machine is determined by the platen, toggle and tie bars. Monitoring the deformation of these three elements, along with that of the mold being used, is crucial. Our strain sensors deliver signals to analyze deformation of the machine and mold, and control it on-line. Sensormate sensors are ideal for R&D, final inspection, and after-sales support. Molding machine deformation is an indirect effect of the locking force, which can be very accurately measured on the tie bars. Our strain sensors can measure with high...

1 WIRELESS LOAD CELL 2 DIAPHRAGM LOAD CELL INJECTION UNIT ALL ELECTRIC MACHINE WITH DIAPHRAGM LOAD CELL INJECTION UNIT ALL ELECTRIC MACHINE WITH WIRELESS LOAD CELL…. Pancake like diaphragm load cell designed for the case in Fully electric Injection Molding machines. The flatbody design allows for easy integration into the Injection unit without adding to the machine length. Available with standardized mV/V output or an EEPROMmodule to allow for higher mV/Voutput for better signal/ noise ratio. Without doubt, as a process parameter the best signal can be found at the screw ante chamber...

INJECTION FORCE DIAPHRAGM VS COMPRESSION LOAD CELL Most of today’s all electric Injection Moulding machines use diaphragm load cells. But there are some drawbacks of this technology. The following list shows the pros and cons of Diaphragm compared to Compression Load Cells. The compression load cells – mostly used in wireless rotating load cells – have excellent technical data. - Up to 2.0 mV/V signal are possible (depending on load introduction part 2 mV/V is ca. 1500 me = 315 N/mm2), with narrow tolerances - Only compression strain; fail safe designs possible - 2.0 mV/V means better...
