1.1 Quality Philosophy

Jingye Lide upholds the quality philosophy of "Quality is Dignity," embedding quality consciousness throughout the entire process — from raw material sourcing to final product delivery. We firmly believe that every powder particle carries our customers' trust, and only consistently reliable products earn long-term partnerships in precision manufacturing.

Our quality management is not achieved by inspection alone — it is engineered in, manufactured in, and prevented in. From alloy composition optimization and real-time atomization parameter monitoring, to precision classification and multi-dimensional product verification, every process step is governed by quantified quality standards and a fully traceable accountability system.

2.1 Core Technology: Water-Gas Combined Atomization

Jingye Lide employs proprietary ultra-high-pressure water-gas combined atomization technology. This process integrates the advantages of both water atomization (high cooling rate, high fine-powder yield) and gas atomization (superior sphericity, low oxygen content), making it one of the most optimized industrial routes for MIM powder production.

Process Principle

Under inert gas protection, molten metal is ejected through a specialized nozzle, initially broken up by high-pressure inert gas (N₂/Ar), then secondarily atomized by high-pressure water jets. The metal droplets solidify into fine, near-spherical powder under extremely high cooling rates. The resulting powder combines near-spherical morphology with low oxygen content while retaining the high fine-powder yield advantage of water atomization.

Key Advantages

1. Near-spherical morphology — Excellent flowability and high tap density for uniform feedstock and mold filling

2. Low carbon and low oxygen — Inert gas protection and strict moisture control ensure powder cleanliness

3. Controllable PSD — D50 precisely adjustable from 6 μm to 12 μm to meet diverse product requirements

4. Batch-to-batch consistency — 12 standardized production lines ensure high reproducibility

5. High fine-powder yield — Industry-leading fine powder ratio with D90 ≤ 25 μm
