Flange-mounted LVDT displacement sensors are increasingly used in injection molding and die casting machines where reliable position feedback is critical. Their robust stainless-steel housing, flanged mounting, and non-contact measurement principle suit high-vibration, high-temperature, and contaminated production areas. Unlike common linear potentiometers, an LVDT has no sliding contacts, so it maintains accuracy and service life under continuous cycling.

In injection molding, these sensors monitor clamp stroke, mold opening, ejector position, and injection unit movement. Flange mounting enables fast alignment on tie bars, moving platens, and ejector plates while saving space. The sensor output supports closed-loop control, helping stabilize mold protection, repeatable ejection, and precise injection positioning. This reduces mold damage, scrap, and cycle-time variation.

In die casting, flange-mounted LVDTs are applied to shot cylinder motion, die locking, ejector stroke, and slide positioning. They resist shock, vibration, coolant mist, and electromagnetic interference when properly sealed and grounded. A robust LVDT helps verify die close position, detect flash or obstruction, and improve casting repeatability. For field installation, choose IP-rated connectors, shielded cable, and stable excitation. Regular zero and span checks maintain long-term reliability. Proper cabling and periodic calibration further protect signal quality in harsh shop-floor conditions.
