In the production of large injection molding machines, the displacement control accuracy of key actions such as mold closing, injection, and ejection directly affects the quality of the products. The MTM3 magnetic levitation slider type magnetostrictive displacement sensor of Miran Technology, with its advantages of non-contact measurement, high precision and long service life, has become the core sensing element for position control of large injection molding machines.

Core application scenarios

Mold closing control: The MTM3 is installed on the mold closing cylinder or the moving template, providing real-time feedback on the mold closing displacement to achieve closed-loop control, effectively reducing defects such as flash and missing mold.

Injection monitoring: Sensors monitor the forward position of the injection screw in real time to ensure precise and controllable injection volume and improve product consistency.

Ejection feedback: Monitor the ejection rod stroke to prevent product damage caused by incomplete or excessive ejection.

Product advantages

The MTM3 series has a measurement range of 50-5000mm, with a nonlinear error of ≤0.05%FS, repeatability of ≤0.0005%FS, and resolution of ≤0.038mm. It supports multiple outputs such as 4-20mA, 0-10V, and RS485. It adopts a non-contact measurement principle, never wears out, has a service life of up to twenty years, requires no recalibration or regular maintenance, and has a protection level of IP65.

At present, the MTM series magnetostrictive displacement sensors of Miran have been widely applied in the position presetting and feedback of injection molding oil cylinders, providing reliable guarantees for the intelligent and precise production in the injection molding industry.

Miran Technology continues to uphold its status as a standard-drafting unit for the Linear Displacement Sensor and Magnetostrictive Displacement Sensor industries. Our commitment to quality is backed by ISO9001, CE, and RoHS certifications, ensuring our products meet global standards.
