As a leading enterprise in the abrasive industry, Jin Rui Company continuously provides high-stability grinding solutions for aerospace, precision tools, automobile manufacturing and other fields with its core product lines-Grinding Wheel, Oilstone and high-end abrasives, such as Green Silicon Carbide, Brown Fused Alumina and White Fused Alumina.

Full scene product matrix, covering the whole process of precision grinding

1. High-performance Grinding Wheel -Technical highlights: Self-developed brown/white corundum substrate combined with precision molding process. -Application value: suitable for rough grinding to fine grinding of hardened steel, alloy steel and other difficult-to-machine materials, taking into account the requirements of cutting force and surface smoothness.

2. Precision Oilstone -Technical highlights: ultra-fine green silicon carbide/white corundum material, micro-pore structure design. -Application value: It can solve the final polishing of ultra-precision workpieces such as molds and measuring tools, and achieve Ra0.1μm mirror effect.

3. Core advantages of abrasives Green silicon carbide (GC) | 9.5 Mohs hardness, sharp edges and corners | Fine grinding of cemented carbide and titanium alloy Brown corundum (BA)| High toughness and impact resistance | Deburring of heavy castings and polishing of welds White corundum (WA) | 99% purity, strong self-sharpening | High carbon steel precision tool sharpening

Technical Breakthrough: Nano-abrasive Coating Technology

-3μm ceramic strengthening layer was formed on the surface of brown/white corundum particles.

-The service life of grinding wheel is increased by 40%, thus avoiding the risk of grinding burn.

-It has been applied to the precision grinding production line of motor shaft of new energy vehicles.

Industry empowerment case

-Tool manufacturing field: white corundum grinding wheel helps precision tool enterprises to achieve ±0.01mm blade consistency.

-Automobile industry chain: Brown corundum heavy-duty grinding wheel is used for batch processing of gearbox gears, and the cost per piece is reduced by 18%.

Commitment to sustainable development

Rotogravure is typically used for stand-up pouches. Folding cartons also use this technique. Rotogravure process consists of an engraved cylinder that is used to transfer the ink to the substrate. The engraved cylinder presses the paper or film onto the gravure cylinder which is smeared with the ink. Rotogravure is not very common when compared to flexographic or lithographic printing, but is still used in commercial printing. It can provide premium quality prints with calibrated colors, has 4 color process and can easily add PMS colors. Rotogravure printing also provides very long lasting prints.

-Invest in the construction of an abrasive recycling center, with an annual recycling capacity of 1,200 tons of abrasive.

-Introducing environmental-friendly water-soluble grinding wheel binder, reducing VOC emission by 90%.
