SCANTECH 3D Digitization Solution for Irregular Curtain Wall

January 31, 2021February 1, 2021 Keith Mills Publishing Editor

With the rapid development of architectonics, irregular curtain walls are applied more widely than ever before. Simultaneously, the rise of such structure poses great challenges to the processing and assembly of aluminum alloy profiles.

The procedure of manufacturing profiles for irregular curtain walls is very complex, it involves structure designing, profile blanking, assembly, delivery and installation. During the process, extremely accurate data are required to produce eligible profiles.

SCANTECH KSCAN composite 3D scanner can obtain the 3D data of profiles, capture surface contour and reflect the deformation in a short time with non-contact scanning, which can improve the efficiency and quality of processing, cut the cost and reduce the reworking. That’s why KSCAN is the perfect choice for profile bending detection, profile blank machine guidance as well as unit plate assembly quality control.

Performance Benefits of KSCAN

Ultra-Wide Scanning Area

Scanning area reaches 1440 mm × 860 mm; finish scanning a 2m*6m unit plate within 5 minutes.

Few Markers Needed

Save 70% time of attaching markers

High Accuracy

Aerospace class ultra-high precision nondestructive inspection; Reach accuracy of up to 0.02mm, volume precision of up to 0.03mm/m.

No Powder Spraying Needed

No harm to the surface of the subject; Suitable for all kinds of scanning scenarios

Profile Bending Detection

Normally, many companies do not have the ability to bend straight profiles so most of them choose outsourcing processes as their solutions. However, this method has attributes of high cost and low flexibility, it even has a risk of leaking confidential scheme. These companies are also unable to inspect the profile in a solid way.

For those companies who can process the profiles, mostly they applied outdated inspection methods such as ruler inspection, which results in a higher deviation and has high requirements to the experience of inspectors.

Traditional Inspection Method

SCANTECH KSCAN composite 3D scanner can proceed non-contact inspection to the deviation of profiles, help with locating the profiles and providing position reference to subsequent processing. One of our clients greatly reduce the rework rate and improve efficiency by 60% after taking our solution.

*Colour map compares scanned data after inspection to digital model of profile and shows tolerance deviations.*

Profile Blank Machine Guidance

After bending the profile, the blank machine is applied to cut the working allowance. When the profile is fixed on the machine tool, KSCAN can scan the whole profile and provide 3D data for programming and processing.

Compared with the traditional method, the KSCAN solution conducts programming and scanning at the same time, processing irregular pieces precisely, standardizing operation procedures, reduce waste as well as enhancing competitiveness.

Unit Plate Assembly Quality Control

Unit plate assembly is the process of integrating the profiles to a curtain unit, during which the length of diagonal and height are required.

KSCAN, with built-in photogrammetry system, provides high-accuracy grid data within 5 minutes. The eligibility of the unit can be tested with the deviation chromatogram generating from aligning the scanning data and designing model. According to the deviation chromatogram, manufacturers can fix the deviation precisely and pack the unit for installation.
