3D Scaning & Quality Inspection

3D Scanning

3D Scanning technology is a non-contact, non-destructive technology that digitally captures the shape and detailed measurement information of physical objects.

Using light patterns or laser lines that's projected on the object are captured with precision accuracy by the scanner’s two cameras, the data captured is used for design and reverse engineering or model validation to the CAD representation.

​At HIRSH we use Zeiss Gom SCAN1 Blue Light Technology that delivers fine meshes with industry proven accuracy and precision.

Our current scanner is capable of creating mesh density of above 0.06mm per scan, when combined with an automatic rotary table a very fine and accurate mesh is formed.

Resulting mesh may be used for reconstructing CAD parts, 3d printed or inspection for quality assurance.

Quality inspection

Different parts need different inspection levels and different methods to validate compatibility to the requirements of the designer, we encourage you to discuss us about your quality requirements and work with us to ensure it can be delivered

We use the industry leading GOM Inspect software from Zeiss to create inspection reports with various degrees of complexity, at HIRSH we offer a wide range of inspection levels:

  • Visual inspection / True fit 

This is our standard inspection every part goes though​.

We also encourage you to provide us with components that need to fit for a true fit inspection.

  • Manual quality inspection report

Manual measurements using lab calibrated measurements tools such as a caliper, height meter and precision pins ​is a time and cost effective method to check compliance of simple measurments.

  • Comparison of scanned part to CAD model 

Your part will be scanned and the resulting mesh will be compared to the CAD model to create a color map of the actual deviations with a simple representation of the parts compliance to the requirment 

  • Full  inspection report to comply with the parts GD&T requirements

Your part will be scanned and the measurement plan will be defined according to the drawing's requirements such as true hole positions, perpendicularity, parallelity and true surface compliance.
