Visual testing in Automotive

In the production of components for the automotive industry, high quality standards are required to achieve longevity and reliability of vehicles. In order to fulfill the high demands, non-destructive visual testing often takes place during the production process.

Engine

In order to achieve the longest possible engine lifetime with efficient function, strict quality requirements are met during production. For example, the cylinder head and cylinder block are visually inspected. The focus is on oil bore holes, oil lines and cooling channels. Any casting, sand or chip residue leads to oil contamination during subsequent operation and accelerates engine wear. During inspection, each oil bore hole and oil line is tested. Depending on the position of a potential defect or material residue, the inspector changes the direction of view by replacing the probe. Quickly interchangeable probes and a handy device ensure efficient operation.

During the final inspection of the cylinder head and cylinder block, the cooling channels are also visually inspected on a random basis.

The infographics give you an overview of the endoscopic inspection in the engine block and the typical probes.

Injection system

In the injection system of a combustion engine high pressures occur during engine operation. Thus the components must be of high quality. During engine operation residues, soiling or incorrectly deburred drill holes in rails, injection pumps or injectors can cause subsequent defects or engine breakdown. In order to ensure the quality, the components are visually tested during production process before they are assembled.

In the infographic you can learn more about typical inspection areas of the injection system.

Brake system

The brake system is one of the most important safety equipment of a vehicle. Components of the brake system are strictly controlled. Deposits, soiling or defects inside components would have strong impacts on the safety and reliability of the system. Thus the master cylinder, the brake caliper, the brake disk or the brake fluid reservoir are visually tested during production process.

The Infographic shows the typical inspection areas of the brake system and  possible defects.

Turbo charger

Efficient combustion of the fuel mixture in the engine puts high demands on a turbo charger. To fulfill these demands, the components of the turbo charger must show flawless processing. To assure quality, for example, the interior turbine and compressor housings are inspected during and after the production process. Chip residues, burr or cavities can be the undesired consequences of the manufacturing process which can be revealed by visual testing.
