3D Inspection for Large and Complex Aluminum Mold with EinScan HX
In recent years, with the rapid development of the automobile industry, electronic information, home appliances, building materials and machinery industries. The structural design of industrial products is becoming more and more complex, the contours of molds are becoming more and more diverse, the proportion of free-form surfaces is increasing, and the precision requirements for mold processing are getting higher and higher, which makes the detection of molds difficult.
Traditional mold inspection methods are generally done manually by contact measuring tools such as vernier measuring tools, micrometers, and micrometers. Only a few indicators such as mold width, height, and depth can be measured, while mold curved and recessed surfaces are difficult to measure. This inspection method is not only complicated and time consuming, but also cannot ensure the accuracy of precision for some large-size molds, making mold inspection a very time-consuming and laborious part of industrial manufacturing.
For this reason, non-contact 3D scanner inspection has received more and more attention from the mold industry, and has gradually become one of the main methods of industrial mold inspection. It has solved the disadvantages of traditional inspection methods in the mold industry and achieved high-quality inspection.
Measurement and inspection process
For this inspection process, the mold factory chose EinScan HX dual blue light handheld 3D scanner. Blue laser + blue LED light source, so that it can adapt to more detection application scenarios. At the same time, because of its portable, easy-to-use, fast and efficient features, it can no longer be affected by the complex environment of the factory, greatly improving the efficiency of quality inspection .
Step 1: Post Points:
Select the laser mode of EinScan HX for scanning. Before scanning, paste positioning marks on the reflective aluminum mold workpiece. Thanks to the wide material adaptability of EinScan HX, there is no need to do powder spray pretreatment.
Step 2: 3D scanning
The laser mode has a scanning speed of 480,000 dots/sec. The technical engineer can directly and quickly obtain the complete high-precision three-dimensional model data of the aluminum mold in just 10 minutes .
Step 3: Three-dimensional inspection
In order to confirm whether the aluminum mold meets the accuracy requirements, the scanned aluminum mold data and the original design digital model are imported into the inspection software Geomagic Control X. After the coordinates are aligned, the deviation comparison analysis is performed using the chromatogram form to obtain the deviation annotation diagram, and finally the inspection report is output.
In the above case, the editor introduced the application scheme of EinScan HX blue laser light source for scanning large-size aluminum mold inspection. It only took 30 minutes from the point scanning to obtain the data to the aluminum mold inspection analysis report. The time arrived saves a lot of time compared to traditional detection methods and solves many parameter problems that cannot be detected by traditional measuring tools .
EinScan HX innovatively blue LED light source and the blue laser light source to a collector device, a machine, compatible with a variety of surface materials and size of the object; both L- fast and efficient ED structured light, and also take into account the accuracy of the laser detail.
In addition, in the fast mode of EinScan HX, for mold samples with obvious characteristics, blue LED light source can also be used to scan, and three-dimensional data can be quickly obtained without sticking mark points, which improves efficiency and meets multiple needs of users. Detection and reverse engineering provide efficient and feasible solutions.
