A practical walk-through of how professional diamond blades are manufactured in a China factory.
International buyers evaluating a diamond blade manufacturer in China should understand the process behind consistent cutting performance. At Protec Tools, production is organized around controlled segment making, joining methods and final inspection—not only finished-goods photos.
1. Diamond powder mixing and segment pressing
Diamond grit and metal bond powders are selected for the target application (concrete, asphalt, granite, tile). Segments are pressed under controlled conditions to balance cutting speed and tool life.
2. Sintering and bond formation
- Sintering consolidates the bond around diamond crystals
- Process control affects wear rate and aggressiveness
- Different bonds are used for abrasive vs hard materials
3. Laser welding or brazing to the steel core
For demanding concrete and construction blades, laser welding creates strong segment-to-core joints. Brazed constructions remain suitable for specific tool families. Core quality, tension and runout are checked before joining.
4. Inspection, packing and shipment readiness
Dimensional checks, weld/braze integrity and appearance inspection are completed before packing. Export packing protects tools during long-distance shipping. Buyers can also request CE/EN13236 documentation for applicable products.
