In injection molding and die casting, reliable position feedback is critical for repeatable cycles and stable part quality. A flange-mounted magnetostrictive displacement sensor is commonly installed on the injection molding machine to measure injection, screw position, mold clamping, ejection, and die-opening positions. Its non-contact magnetostrictive measuring principle offers high resolution, long stroke capability, and strong resistance to shock, vibration, oil mist, and temperature variation. The flange mount simplifies mechanical installation and alignment, shortens maintenance time, and supports retrofits on existing machines. In field use, the sensor enables closed-loop control of injection speed and position, helping reduce flash, short shots, and dimensional variation. During die casting, it monitors mold clamping and shot position under harsh conditions, improving cycle consistency and equipment safety. Proper sealing, cable routing, and grounding are important to avoid electromagnetic interference. Regular calibration and inspection keep measurement accuracy stable. Typical installations include the injection unit, mold closing unit, ejector system, and die height adjustment. Stable feedback improves cycle repeatability and reduces reject rates, while analog or digital outputs integrate easily with PLC and servo controllers. Overall, the sensor is a practical choice for intelligent injection molding and die casting production. This supports smart factory monitoring.
