The Application of Miran Linear Displacement Sensors in EVA Injection Molding Machines

2026-08-26

In an EVA injection molding machine, the linear displacement sensor (often referred to as an "electronic ruler") is a crucial feedback component for achieving precise injection molding. It mainly ensures the accuracy and stability of the product by monitoring the displacements during key actions such as injection and mold closing.

It is mainly applied in the following key aspects:

1.Precise injection control: Installed on the injection screw, it monitors the displacement in real time to ensure precise injection volume each time, avoiding product shortage or flash formation.
2.Mold closing position monitoring: Precisely controls the opening and closing position of the mold to prevent mold collision and provide a basis for setting the clamping force.
3.Ejection and core-pulling control: Monitors the ejection distance of the product and the position of the slider to ensure a smooth ejection process and prevent damage to the product or the mold.

The environment of EVA injection molding machines is usually hot and contaminated with oil. Therefore, the sensors used need to have high protection levels and the ability to withstand high temperatures .The Miran linear displacement sensor can precisely meet the customer's requirements for accuracy and temperature.According to the installation space and precision requirements, the Miran pull rod type or slider type is usually selected.

Features of the Miran Linear Displacement Sensor:

1.Long service life.

2.Excellent linearity, linear error accuracy: Some models are better than ± 0.04% FS.

3.Resolutionbelow0.0lmm,resolution: uninterrupted resolution.

4.High repetition accuracy,less than 0.01mm
