          Reverse design of automobile intake manifold

          Automobile intake manifold reverse design case

          The plastic intake manifold has the characteristics of light weight, poor thermal conductivity and low air resistance. Customers need to copy the 380×330×180 intake manifold, import the data into the computer and modify it slightly, then open the mold for efficient and low-cost mass production.

          Practical problems

          The intake manifold is a relatively complex structure, not only has a lot of dead angles, but also the shape of the ribs on the surface varies. If you use a common 3D scanner on the market, there may be problems such as data splicing and poor precision of the ribs.

          The intake manifold refers to the intake line before the carburetor or throttle body to the cylinder head intake. Its function is to distribute the air and fuel mixture from the carburetor or the

          throttle body to the intake ports of each cylinder to maintain the safety of driving. The tolerances of the connection between the intake manifold and the engine are very strict. The installation of the sensors and actuators on the manifold is also very accurate. Therefore, no large errors can be expected from the data acquisition.

          According to the complex structure of the intake manifold and high precision requirements, Hualang engineers use an industrial-grade 3D scanner: HL-3DSV+. It has the advantages of fast scanning speed, small optical distortion and high scanning precision.

          Scanning steps:


          Spraying the developer (increasing the contrast of the background color of the workpiece surface to obtain more and better scan data)

          Post mark points (automatic stitching of scanned data)

          3D scanning
          (One-click shooting, easy to operate, change the angle of the object or device, so that the lens can capture every face of the object)

          Point cloud data, STL data (high-precision 3D data, can be transformed into various formats for reverse design)

          Data import machine processing equipment to process the mold, the purpose is achieved
