“We’ve been using SinoDiam’s micron diamond powder for optical lens polishing for over 3 years, and it has become an essential part of our precision finishing process. Before switching to SinoDiam, our team faced frequent issues with inconsistent particle sizes and uneven polishing results, which led to higher rework costs and downtime.
Since adopting SinoDiam industrial diamond powders, the difference has been remarkable. Each batch delivers ultra-uniform particle size distribution, high purity (over 99%), and stable performance—boosting our polishing yield from 85% to 98%. The surface quality and mirror finish of our lenses have improved significantly.
When we needed a customized ultra-fine diamond powder for a new project, SinoDiam’s technical team responded quickly and sent a trial batch within 5 days. Their dual-factory supply system in China and Thailand ensures fast delivery and consistent availability, even during supply chain disruptions.
For any precision machining or optical polishing manufacturer looking for high-quality diamond micron powder, SinoDiam is a trusted and reliable partner that delivers both performance and value.”
