Application:

Precision mold inspection

Used for verifying the cavity dimensions of precision molds such as injection molds and stamping molds, ensuring that the core aperture matches the micrometer level tolerance on the design drawings and avoiding burrs or dimensional deviations in the molded parts.

Hydraulic component quality inspection

Used to detect the channel aperture and fitting size of hydraulic valve blocks, cylinder liners and other components, verify whether they comply with hydraulic standards such as ISO 4400, and ensure system sealing and flow stability.

Notes:

Ultra high precision, strict tolerance control

Adopting precision grinding and calibration technology, it can accurately match the strict tolerance requirements of small apertures, ensuring reliable measurement results.

Super hard and wear-resistant, long-lasting stability

The core components are made of high-quality high carbon tool steel, which has undergone vacuum quenching or nitriding treatment on the surface. Its wear resistance is stronger than that of ordinary steel measuring tools, and long-term use is less likely to cause dimensional deviation due to contact wear. It is suitable for high-frequency and high-strength testing scenarios.
