Products Description
Bottom Shell Casting is a common metal part, usually used in automobile engines, mechanical equipment and other fields. Bottom shell are usually made of aluminum alloy, cast iron, and other materials with good strength and wear resistance. Their design can be customized to ensure that they meet specific engineering requirements. Bottom shell play an important role in the manufacturing industry and are widely used in various industrial fields. If required, sump castings can be manufactured by selecting the right material and process according to the specific project requirements.
Automotive engine oil pan materials and the corresponding process are: cast iron or cast aluminum parts - single-layer sheet steel stamping parts - die-casting aluminum alloy parts - (metal / plastic / metal) sandwich composite parts and so on.
Engine oil pan castings itself attributes directly affect the quality of processing, in which the hardness value is to determine the casting of an important indicator of processing.
(1) Brinell hardness: mainly used to determine the castings, forgings, non-ferrous metal parts, hot-rolled billets and annealed parts of the hardness of the determination range ≯ HB450.
(2) Rockwell hardness: HRA is mainly used for high hardness specimens, determination of hardness higher than HRC67 above the material and surface hardness, such as cemented carbide, nitrided steel, etc., the determination of the range of HRA>70. HRC is mainly used for steel parts (such as carbon steel, tool steel, alloy steel, etc.) quenched or tempered hardness determination, the determination of the range of HRC20 ~ 67.
(3) Vickers hardness: used to determine the hardness of thin and steel plate parts, can also be used to determine the hardness of carburized, cyanide, nitriding and other surface hardening parts.
