3D Quality Control of Glasses to Meet the Tough Specifications

3D Quality Control of Glasses to Meet the Tough Specifications

Apr 29, 2022

The glass industry has its own unique sets of requirements for quality control ranging from edge inspection, thickness calculation, spectral reflectance, color measurement, and more.

Curved glass is among the most commonly used material. It has to be thoroughly inspected to check whether it has met the strict tolerances required in industrial manufacturing.

Curved glasses

It is time-consuming and highly costly to inspect glasses using traditional approaches due to their limited measuring areas and non-efficient contact measurements.

To further improve the efficiency of product quality control measurement, manufacturers need to adopt new technical methods. Using a handheld 3D scanner for quality control can effectively overcome this challenge.

This blog will take the following case as an example: 3D scanning and inspection of medium-and-large scaled curved glasses.

The glass inspection can be enhanced with our innovative optical measurement equipment KSCAN-Magic. The case shows us how the 3D scanner KSCAN-Magic can be used and what benefits it can bring.

Challenges of inspecting glasses

3D Laser Inspection of Medium-and-large Scaled Curved Glass


The large size of glasses is one of the main challenges. When inspecting objects with 3D scanning,

alignment errors can stack up as the scanning volume grows.

Technicians need to conduct on-site measuring of glasses to avoid scratching the delicate glass surface.

Besides, it is necessary to analyze elements like compressive and tensile stresses of glasses to verify whether they are qualified. A piece of measuring equipment that delivers high-quality and precise results is needed.

How do circumvent these challenges by 3D scanning?

Benefits of 3D Quality Control Measurement

Built-in Photogrammety Improves Accuracy

With its built-in photogrammetry, the blue lase 3D scanner KSCAN-Magic allows users to measure objects of all sizes and obtain quality control measurement results with an accuracy up to 0.020 mm.

When it comes to 3D scanning large-scale objects, photogrammetry combined with large-area scanning can reduce alignment errors, which ensures precise and highly repeatable results.

When scanning curved steel glass (4m*4m) for large buildings, technicians and engineers can use KSCAN-Magic’s integrated photogrammetry.

It is a way to capture the part’s general geometry, and then obtain its complete 3D data using ultra-fast and hyper-fine scanning modes. With KSCAN-Magic, the technician obtained these 3D quality control statistics for manufacturing optimization.

Portable, Flexible and Robust

It is risky to move large-scale glasses around, as they are fragile. Optical 3D scanner KSCAN-Magic series is the key to overcoming the challenge as it is flexible and portable. It can be transported with minimum effort and conduct 3D measurements and 3D laser inspections anywhere you want.

On-site 3D measurements and inspections

Traditionally, when inspecting a certain type of part, a special 3D laser inspection tool is needed. The costs of purchasing, transporting, and storing various inspection tools can be expensive.

Thanks to its non-contact measurement, the handheld 3D scanner KSCAN-Magic can scan parts in different sizes and shapes. Thanks to its intuitive settings, a beginner can get familiar with it within just one day.

Portable 3D scanner

Accurate, Efficient, and Intuitive

It is not easy for traditional inspection tools to perform well inaccuracy without compromising on efficiency. Composite 3D scanner KSCAN-Magic enables users to get precise measurement results by offering five standard working modes.

It’s innovative large-area scanning (infrared lasers) can scan an area as large as 1440mm*860mm, efficiently reducing the scanning sessions.

Using the hyperfine scanning mode, the technician easily captured the complete data of the glass at a resolution up to 0.010mm.

With accurate and high-resolution 3D statistics for quality control at the fingertip, these technicians can effectively analyze elements such as surface profile and gap and flush. It is helpful to meet the needs for further analysis and deliver an intuitive report.

Hyper-fine scanning mode

When using KSCAN-Magic to inspect the automobile glass (shown above), the technician obtained complete data in 10 minutes. He then imported 3D data into 3D software to generate a 3D model.

The model was compared with the original CAD model to obtain the final analysis report. Elements such as surface profile and gap and flush features are intuitively represented.

Intuitive reports

Data Analysis and Archiving

The inspection results can also be saved as digital backups, which provides a data basis for further product development, optimization, and wear analysis.

Scan data for archiving

As one of the greatest inventions in human history, glass has become one of the critical materials in life. Quality control of glasses is essential for the functionality and safety of products.

Handheld 3D scanner KSCAN-Magic is a good choice for enhancing the efficiency of inspecting large-scale glasses due to its portability, precision, and efficiency.
