Quality Assurance

Magnet Quality Assurance

We possess comprehensive testing equipment and a strict quality control system to ensure the performance and stability of each batch of magnets.

Magnetic testers: Test magnetic flux, Gauss value, remanence, and coercive force to ensure stable magnetic strength.

Image measuring instruments and calipers: Accurately check dimensions and tolerances to ensure products meet design requirements.

Salt spray testers: Simulate harsh environments to test the corrosion resistance of coatings.

High-temperature test chambers: Verify the stability of magnets under different temperatures.

Tensile testers: Ensure the magnet’s holding force meets the required application requirements.

Through these advanced testing equipment and standardized processes, we are able to provide customers with high-quality, reliable, and durable magnets.

KEYENCE VR-5000-3D contour detector

Measuring the shape and roughness oftheproduct, from the whole to the local details,can be measured by one device, and themeasurement range is 5 times that of theprevious one. Equipped with “automaticprocessing and setting function” to eliminatehuman measurement errors.

Zeiss 3D Measuring

High-density scanning points, high reliability and high repeatability measurement results can be obtained; probe connection method and length range are widely applicable;ceramic parts and long bearing seat ensureaccuracy and reproducibility, small base andbackpack control The cabinet saves more
space.

zMAGCAM 3D MagneticField Scanner

Using 128*128 matrix array Hall probes, the surface scanning of the magnetic steel quickly shows the magnetic distribution of the surface. The software is compiled based on Python, and the analysis results are more intuitive and convenient.

Inverted metallurgical

Equipped with large-field eyepieces and long-distance plan achromatic objectives, no cover glass, large and clear field of view. With locking and limiting device, coarse movement tightness, fine movement scale value and halogen lamp can be adjusted. lt can switch between normal observation and polarized light observation, and can perform light-transmitting photography.

Magnetic declination detection

The three-dimensional Helmholtz coil is connected to the three-component fluxmeter,the magnet is placed on the sample stage,and the magnetic flux value, magnetic moment and angle values of the three components can be obtained through specia! software.The software can display measurement data and perform statistical analysis on it, and display MX, MY, MZ, M and magnetic declination a at the same time.

Mitutoyo Rockwell Hardness Tester

Generate multiple Rockwell, Rockwell surface and Brinell hardness test force levels;Dolphin-nosed indenter measuring arm design is convenient for inner and outer contact; real-time electronic force measurement control ensures high-precision load, effectively avoiding test force overload.

ICP composition analyzer

Qualitative, semi-quantitative and quantitative analysis of major, trace and trace elements in samples. Based on the solid detector, it consists of a sampling system, a high-frequency generator, a plasma torch, an optical path system, a detector, analysis software and a computer system. The computer controls the instrument to monitor the instrument and automatically adjust the parameters.

CCD visual inspection

Fully automated visualinspection can inspect 100% of the products, with high inspection accuracy and fast efficiency, which can meett he inspection needs of mass production.
