Poly-crystalline diamond powder is synthesized making use of the extremely strong power by explosives. We take pride that our explosion facility is one of the largest one in the world concerning diamond synthesis.
At the strong request from various industry, university and government, we actively cooperate in making specific explosion and synthesis experiment.
Our Explosion Facility for Diamond Synthesis
Production Process
After the synthesis process, the refinement process to remove impurity, the milling to process adjust particle size and shape, the grading process to classify the extremely precise size range and the inspection process to control quality strictly based on our company specification.
