99 Sintered High-Density Aluminum Channel Blocks - Top Quality from China Suppliers & Factory
Manufacturing Process
-
1Raw Material Preparation High-purity alumina powder and various particle grains size are prepared.
-
2Forming The raw material is formed into the desired shape using techniques such as casting or extrusion.
-
3Sintering The formed blocks are sintered at high temperatures to achieve the required density and mechanical properties.
The Advantages
99 dense alumina channel blocks are no glass pollution, eliminate glass impurity, bubble, ‘Cat-Scratch’ and reducing defects of glass production. The production yield-rate can be highly improved, especially for crystal glass, cosmetic glass, perfume glass, high-grade container glass etc.
