What's an oil pan?<\/h2>\n\n\n\n

The oil pan is located in the lower part of the engine crankcase, also known as the lower crankcase. It is used to seal the crankcase, collect the lubricating oil produced by engine friction back to prevent outside dust impurities into the lubricating oil.<\/p>\n\n\n\n

Classification of oil sumps.<\/h2>\n\n\n\n

These are the common types of oil sumps<\/p>\n\n\n\n

Plastic oil sump<\/h3>\n\n\n\n

Plastic oil pan means that the material of the oil pan is engineering plastics, and it is made of injection mold <\/a> Processing technology manufacturing, this material made of oil pan quality is lighter and thinner, design freedom is higher, the price is relatively low, more convenient installation. Has a certain degree of toughness. However, the high temperature resistance and corrosion resistance of the plastic oil pan is relatively poor, relatively short life, suitable for low working temperature, low frequency of use, the weight requirements of the environment.<\/p>\n<\/div>\n\n\n\n

Aluminum oil pan<\/h3>\n\n\n\n

Aluminum alloy oil pan is made of aluminum alloy, so it has good heat dissipation performance, light weight, strong corrosion resistance, can withstand a large amount of impact, and has a certain degree of strength. However, the aluminum alloy oil pan is usually made by die casting, which is a process with low mass production cost, but high mold cost and not suitable for customized manufacturing. It is usually used by automobile factories for mass production. In order to further meet the demand for customization, some customers use low-pressure casting or gravity casting, the process can choose low-strength molds just (relatively inexpensive) to greatly reduce the cost of the product is relatively thicker, the performance of the heat treatment is higher than the die casting, usually in the tuning car, racing car, vintage cars and other customized industry with more.<\/p>\n<\/div>\n<\/div>\n\n\n\n

iron oil sump<\/h3>\n\n\n\n

Iron oil sump according to the thickness of different process casting, there are stamping oil sump (about 2mm) and cast iron oil sump, stamping oil sump through the press brake with robotic arm<\/a> Stamping made of light weight, manufacturing process, lower cost, suitable for mass production, however, due to the stamping of the oil pan is relatively thin and stamping process, product rigidity is poor (stamping equivalent to the product received an impact), can not manufacture complex structures, usually can not be repaired and can only be replaced. Cast iron oil bottom as a result of thicker after t6 heat treatment has a particularly high strength (much higher than aluminum alloy) weight, however, the shortcomings are also very obvious, the weight is greater, the cost is also higher, the lack of toughness, easy to crack by impact. Manufacturing cost is more expensive.<\/p>\n<\/div>\n\n\n\n

Aluminum alloy oil pan production process.<\/h2>\n\n\n\n

Ningbo Hexin aluminum alloy oil pan manufactured by die-casting and low-pressure casting, gravity casting of the three production processes, low-pressure casting and gravity casting in addition to the production of different machines process is relatively similar.<\/p>\n\n\n\n

Ningbo Hexin selects electrolytic aluminum ingots (non-recycled aluminum) from listed factories of Yunnan Aluminum Industry, which are good materials with good products. From the material to ensure that the product new energy is excellent and stable.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n
