Spectrometer: This advanced material inspection equipment meticulously detects the chemical composition of raw materials, ensuring they meet stringent incoming material acceptance standards.

Universal Testing Machine: Our precision-engineered device evaluates raw material performance by rigorously testing tensile strength, yield strength, elongation, and area shrinkage to guarantee exceptional quality.

Metallography: Post-heat treatment samples are scrutinized under a microscope to observe quenching and tempering structures, ensuring heat treatment qualifications are met to the highest standards.

Three Coordinates: This state-of-the-art technology conducts spatial dimension detection, digital model dimension verification, and meticulous appearance dimension measurement for unparalleled accuracy.

Bench Testing Machine: Innovatively developed in-house, this machine measures product dimensions while simultaneously testing stiffness. It also verifies the fatigue life of both product assemblies and spring eyes.
