          The 3D scanner can scan the car bumper to obtain high-precision 3D data, improve the second development efficiency of the car bumper, and ensure the accuracy of CAD design results.

          Practical problems

          1. It is very cumbersome and time-consuming to use traditional methods (such as inspection tools, fixtures, three coordinates, etc.) to measure the car bumper, and it is not easy to accurately and quickly measure and detect the shape of the car bumper.

          2. The automobile bumper has many curved surfaces and buckle parts, and the bumper is relatively large in volume and easy to deform. The general three-dimensional scanner is difficult to quickly and accurately obtain the three-dimensional digital model of the automobile bumper.

          The customer wants to further improve the production of the automobile bumper, save production costs and improve product qualification rate. Therefore, Hualang 3D engineers provide professional solutions - 3D scanner HL-3DW (fast access to high-precision 3D data of car bumper) + reverse design software Geomagic Studio (convert car bumper point cloud data to triangular mesh) Face data) assisted the company in the secondary design of the car bumper.

          1. Preparation in the early stage:
          Spraying the developer: Improve the background color contrast of the sample surface for better scan data.

          Paste mark points: Make the acquired data be positioned and stitched in the scanning software.

          2. 3D scanning:

          Hualang 3D engineers use the 3D scanner HL-3DW to quickly obtain high-precision 3D data for car bumpers. The 3D scanner features an ultra-large scanning format, a portable design, extremely fast scanning speed, high precision and high stability. It takes only 30 minutes to get the 3D data of the automobile auto bumper with an accuracy of 0.03mm. Using the acquired three-dimensional data of automobile bumper, the secondary design of the automobile bumper is accelerated, and other relevant departments are provided with reliable parameters, which accelerates the production of the automobile bumper.
