Baoding Guokun specialized in sand molded casting, green sand casting, resin sand casting, precoated sand casting, shell molding casting with grey iron, ductile iron, cast iron, cast steel, cast aluminum, bronze, brass, copper with high quality and competitive prices and high quality. All of our customized metal castings are manufactured accoridng to custoer's requirements, drawings, design or samples.
Cast Iron 65-45-12 Dura-bar is a ductile iron grade offering high wear resistance, strength, durability, ductility, with excellent consistency, impact resistance, machinability, and finish. Tensile and Yield Strength are comparably strong to 1040 steel in the "as-rolled" condition.
65-45-12 Dura-Bar is manufactured through the Continuous Cast process, which is actually closer to extrusion than casting. However, this process causes all of the impurities in the molten iron to float to the top of the crucible, away from the metal being used to create the bar. This removes porosity and other impurities common to other cast iron grades.
65-45-12 can be oil quench hardened from 1600 F (885 C) to a minimum hardness of Rockwell C 50 on the outside of the bar. The inside diameter hardness will be less than Rockwell C 50.
It is typically used in the automotive and power industries for gears, rotors, pistons, valves, rollers, bushings, chucks, flywheels, pile drivers, rams pulleys, housings, and motorcycle disc brakes.
| Item | Green Sand casting | Resin sand casting | Precoated Sand Casting or shell mold casting | Automatic Molding Line |
| Process | Green Sand Casting is the common sand castings made using wet sand or “green sand” molds. | Resin sand casting process is using the resin sand as the molding material. Resin sand is a kind of mixture of quartz sand and resin | The main molding material is the pre-coated phenolic resin sand, which is more expensive than green sand and furan resin sand. | Green sand molding line & resin sand molding line |
| Advantage | Usually for large steel castings and iron castings. | Suitable for custom castings with rough surface requirement and low unit cost. | high dimensional tolerance, good surface quality, and less casting defects | High production rate, only suitable for small & medium castings, require annual quantity |
