3D Inspection – Efficiently Control the Quality of Sheet Metal Stamping

3D Inspection – Efficiently Control the Quality of Sheet Metal Stamping

Compared with casting and forging, sheet metal stamping is thin and light. When using precise moulds, it can reach extreme accuracy in micron level, high single point repeatability and uniform specifications. However, the finished sheet metal stamping usually gets obvious deformation and deviations after pressing and welding. Such unqualified products will have a bad influence on assembly, therefore, quality control to guarantee products’ accuracy is a very significant procedure.

What manufacturer need?

For an auto parts manufacturer, 3D inspection always goes to finished products to examine the accuracy, which is a common way to confirm whether the products are qualified or not. Traditional mechanical measurements, however, are difficult to obtain accurate 3D data and usually time-consuming. Hence, the manufacturer hopes to carry out an optimal 3D scanning to improve detection efficiency.

ScanTech 3D solution

Taking a manufacturer’s requirements into consideration, ScanTech decides to use handheld 3D laser scanner PRINCE. This 3D scanner owns global initiative technology – dual laser scan mode.

● The red and blue laser scan mode can be flexibly switched according to different scanning demands.

● The Mode R (red laser) keeps the fast measurement rate of normal portable 3D scanners, while hyperfine Mode B (blue laser) features in extreme details and accuracy as structured light 3D scanners.

● PRINCE 3D scanner is pretty user-friendly. It can quickly obtain an object’s 3D data after attaching markers and scanning.

● Easily get deviation values by comparing the 3D model with the original CAD model.

These advantages of PRINCE 3D scanner definitely realize what manufacturer pursues.

Through the onsite operation, we can see that the whole process is very time effective and simple. Users can annotate on key areas of chromatogram to acquire specific deviation values and correct the errors. This is how 3D scanning contributes to performing quality assurance on machinery manufacturing. The PRINCE 3D scanner is proved to fulfill customer’s requirements with high resolution and ultra-fine 3D data.
