Stringent testing systems ensuring flawless grain performance and durability.
Every batch supplied by GDM Diamond undergoes a sequence of mechanical and chemical checking procedures. We ensure **100% batch traceability** from catalyst raw materials to finished packaged powders.
Our testing methodologies align with federal European standardizations (**FEPA**), guaranteeing that our clients receive consistent particle size distributions and thermal index integrity.
Certified Quality Management System for synthetic diamond sourcing and micron particle sizing.
Grit and micron size grading verified according to standard European FEPA sifting parameters.
Our quality control labs are equipped with high-precision testing systems to evaluate crystal physics.
Uses laser diffraction to check the exact Particle Size Distribution curve. Guarantees narrow size ranges with zero oversized grains that could scratch substrates.
Advanced image analysis evaluates crystal circularity, aspect ratios, and surface roughness. Allows us to sort irregular flat/needle-like crystals from blocky grains.
Measures the Thermal Toughness Index (TTI) after exposure to temperatures above 1100°C. Ensures diamond grains withstand metal bond sintering heat.
Checks the concentration of trace metallic inclusions (nickel/iron catalysts) trapped inside the crystal grid, ensuring low magnetic response and high purity.
We provide full batch-specific Technical Data Sheets (TDS) and material safety documents. Reach out to our quality office for certificates.
