In a recent article on 3D scanning for the automotive industry, we have talked about how 3D scanning can be used in product development, inspection of stamping parts, and supplier quality assurance. Today, we will dig into how it can be applied in the inspection of car body and explore more applications.

Quality control always comes as a priority to consider during manufacturing. Vehicles not produced or assembled properly, even a minor error, can put people’s lives at great risk.

Inspection of Car Body

·Dimensional Inspection
Manufacturers face constant challenges in monitoring the whole manufacturing process when using traditional inspection gauges due to their limited efficiency. Moreover, each complex feature requires a kind of inspection tool, which increases the complexity of the task. These non-efficient inspection tools fail to meet the strict fit-and-finish standard.

An inspection device that doesn’t require complicated setups and that can handle various inspections tasks can be the answer to the question. That is where Scantech comes in. We provide high-tech 3D scanners such as composite and handheld 3D scanner KSCAN and optical-tracking 3D scanner TrackScan. With a simple setup, these portable 3D scanners allow users to change the critical parameters such as measurement parameters and exposure settings flexibly according to the feature and materials of the parts to be inspected.

In this way, the manufacturer can scan sub-assembly in real time and get a precise digital twin of the parts. Complete, precise, and traceable data of the parts manufactured can serve as a basis for finding root causes of potential issues that may arise later.

One major advantage of our 3D solutions are the uniform and efficient evaluation method. It enables manufacturers to access complete data of inspection from different manufacturing steps and systems. By integrating all the data into one base, automakers have the confidence to monitor the manufacturing efficiently and fitting of the cars’ design.

Trial Production Run
·Automotive Gap & Flush Inspection
Scantech’s 3D scanner also plays an important role in trial production run. A major automotive manufacturer in China adopted our scanners to record various kinds of data for manufacturing. According to previous inspections, the parts manufactured do meet the strict dimensional specifications.

However, the engineers identified that there was wind noise when driving the car at a high speed. When driven at a higher speed, the air outside the vehicle is at a lower pressure as compared to the wind inside the car. A car that is less aerodynamically designed is more prone to such wind noises. To ensure a smooth and quite ride for further customers, the manufacturer must identify the hidden reasons.

By tracing the data captured by a 3D scanner, this automaker analyzed the dimensions of the door surface and gaps between doors and mounted vehicle bodies. Technicians conducted on-site inspection with our composite 3D scanner KSCAN-Magic to identify problems.

Scantech’s lightweight 3D scanner is equipped with five working modes including large area scanning and superfine scanning. It is capable of capturing precise data of surfaces and gaps in car doors. With this efficient measurement method, and the precise data delivered, engineers verified the possible reasons and were able to locate the problems quickly.
