In metal casting, a variety of casting defects, such as pores, shrinkage cavity, cracks, inclusions, and residual sand, will appear. The casting parts such as engine cylinder block, cylinder head, gearbox, motor shell, connecting rod and others on the automobile can be scanned by X-ray CT to reveal various internal defects.
The matching of the internal structure of a precision assembly is a key factor to ensure its performance. CT scanning can non-destructively observe the complex assembly structure, find internal foreign objects, measure the offset size, and comprehensively evaluate the assembly quality in three dimensions.
With the rise of new energy vehicles, the safety of lithium batteries has attracted the attention of manufacturers and users. X-ray CT is an important method for non-destructive analysis of lithium battery manufacturing defects.
The harsh use environment (high and low temperature, moisture and vibration) of automotive electronics and long use cycle bring high requirements on quality and reliability of electronic devices. X-ray testing technology is required in verification and evaluation, failure analysis, quality inspection, and full production testing.
