Our Castings Quality Control
Hardness Test
For Brinell testing, we use a spherical penetrating body to press into the surface of the castings. For Rockwell, a bullet- or cone-shaped penetrating body is used, and for Vickers, we use a diamond pyramidal body.
Magnetic Particle Inspection
Our wet MPI method provides enhanced sensitivity, detecting discontinuities with a maximum depth of 1/4 inch. We carry out MPI testing on heat-treated or machined castings to ensure that there are no defects.
Material Test
To ensure the veracity of the material certification provided by the factory, we conduct a chemical analysis of a small piece before each batch of metal ingot is used. We also inspect the molten metal before pouring and conduct testing on the completed samples.
X-RAY TEST
At keming machinery, we use X-Ray testing to detect various defects including gas porosity, gas holes, micro-porosity/shrinkage porosity, shrinkage, cracks, dross, cold shuts, segregation, misruns, and diffraction mottling.
Our International Certificates
KEMING is well-versed in a wide range of industrial standards. Our products and services meet strict quality requirements. We comply with many important standards from around the world. These include the Chinese GB standard, which ensures safety and quality in China. We also follow the American ASTM and AISI standards, known for their rigorous testing and material specifications.
