D-M-E Company (Madison Heights, MI) has introduced new strain-gage-based sensors and added a smaller 125-pound size to its 500- and 2,000-pound product line. These sensors are used in conjunction with auxiliary recording and control equipment for measuring pressures in injection, die cast and transfer molds. The new 125-pound model is ideal for use with smaller ejector pins and is suitable for small molds or applications where water lines, support pillars or other mold features inhibit the use of slide sensors. The sensors allow molders to better control the quality output of their process. By precisely measuring the force of plastic in a mold cavity on every shot, users can be assured that their parts are uniform and properly filled. If an error is detected, the part can be scraped without the need for further testing or quality inspection. Because each sensor is electrically identical, they have the same output—practically eliminating the need to recalibrate the readout system when sensors are exchanged. This makes errors in calibration nonexistent and operators spend less time setting up control systems and recorders.
