visual inspection


In the production of automobiles and in the manufacturing of components for the automobile industry, high quality standards have been set to achieve longevity and reliability of vehicles.
The safety-relevant parts of the power train and the braking system are especially subject to exact examinations.
In order to fulfill the high demands, a non-destructive optical test often takes place during the production process; this requires a high level of solidity and reliability of the visual inspection system, and also a high level of image quality. In addition to their use in production, visualization systems are also used in research and for maintenance and service.

Testing fuel injectors

Fuel injectors are becoming ever smaller, compacter and more efficient. This means increased demands on manufacturing and testing processes. Residues, soiling or an incorrectly deburred drillhole in the injector can later lead to damage or inefficiency when starting and running the engine.
With small, very thin rigid endoscope systems such as SCHÖLLY FlexiVision 100 with FlexiScope 3, problems can be visually detected and subsequent defects or an engine breakdown can be avoided. The FlexiScope 3 camera handpiece system can also be adapted to every testing requirement, for example, to different drill diameters.

Testing hydraulic parts

Deposits, contamination or surface damage on hydraulic parts can all have a strong influence on quality and reliability. You can examine not only straight but also difficult-to-reach openings and drillholes of hydraulic parts with visual inspection systems such as the SCHÖLLY FlexiVision 100 with FlexiScope 3.

Testing motor parts and casting

Residue-free, clean drillholes and openings of casting or engines such as, for example, oil and aircore drilling must be guaranteed to assure flawless performance of a motor. Because of the difficulty of reaching the openings and drillholes, or because of their great length, robust videoscopes such as the SCHÖLLY EzyScope (mobile or stationary) are used for testing casting and engine openings.

Research / development of engines and exhaust systems

Innovative engine research for the future demands an understanding of all of the involved processes today, especially the fuel behavior upon injection or the atomization behavior of materials for exhaust purification; but also the combustion itself is becoming more and more important in engine development. To observe this behavior live and to be able to comprehend it makes the job much easier.
SCHÖLLY high-temperature endoscopes make it possible to observe these processes visually or with a camera at a PC. Combined with an HD camera, the pictures are razor sharp.

Inspection of turbo chargers

Low emission limit values combined with more efficient combustion of the fuel mixture in the engine provide for high demands on a turbo charger. To fulfill these demands, the components of the turbo charger must display flawless processing. To assure quality, for example, the interior turbine and compressor housings are checked endoscopically during and after the production process. Chip residue, burr or cavities can be the undesired consequences of the manufacturing process which can be revealed by visual inspections. For an efficient and above all a time-saving optical inspection, the borescope is introduced through the side opening of the  volute, the spiral-shaped cavity. For this procedure, borescopes with a small probe diameter and an adapted viewing direction are best. Customized solutions with pre-curved probes enable testing in almost inaccessible canals. The internal inspection can take place manually or by automation.
