How to Quickly Perform 3D Inspection on Complex Mould?

Moulds are comprised of different even very complicated parts, therefore, quality control becomes one of the key procedures for making well-qualified moulds.  Manufacturers usually use traditional tools such as vernier calipers and micrometers. However, such tools are not convenient to operate, besides it’s difficult to accurately measure the concave and curved surface.

What Mould Manufacturer Needs?

Due to many differences between processing equipment and technologies, mould often fails to meet the required precision. The mould manufacturer originally uses CMM that is not time effective:

  • Mechanical wear of probe and object’s surface
  • Limited applications: hard to measure soft surface
  • Measurement speed restricted by mechanical motion
  • Limited measuring range
  • Sensitive to temperature and humidity
  • Unable to capture the full 3D data of the object

However, 3D scanners can accurately obtain the ultra-high 3D data by non-contact measurement:

  • Much flexible
  • Easy to scan large objects
  • High performance in scanning complex and curved surface
  • Easily scan black and specular materials
  • Work normally in direct sunlight, which is useful for outdoor operation
  • Dynamic measuring: free movement between scanner and object

In order to improve work efficiency, the customer chose ScanTech handheld 3D laser scanner to quickly inspect and make data analysis.

ScanTech 3D Solution

Our experts use handheld 3D scanner HSCAN to eliminate the deviations for mould inspection.

Step 1: Attach markers without spraying powder

Step 2: Quickly capture 3D data on curved and complex surface of the moulds

Step 3: Transfer the 3D data to scan software ScanViewer

Step 4: Get comprehensive deviations by comparing the obtained 3D data with the original 3D model and generate inspection reports
