A new generation of high-performance engine oil pan was produced by using the synchronous design to improve the product structure and adopting high pressure oil pipe insert special process.By improving the steel pipe shape and process to narrow shape tolerance

the positioning accuracy and consistency were improved.By modifying the mold design

stability of the steel pipe insert installation and die casting process was improved.Through steel preheating and knurling process

the problem of products leakage was eliminated.In addition

steel pipe insert cleaning and antirust process was developed to solve product pipe rust in the process of die casting and processing

effectively ensuring the product high pressure oil airtight performance and cleanliness and making a successful product design and production.
