The casting X-ray inspection system, with its advantages in non-destructive testing, focuses on "quality control" and "safety protection", and is widely used in multiple industries with strict requirements for casting reliability. The core scenarios are as follows:
In the field of automobiles and new energy vehicles, the focus is on testing power and safety components. The engine cylinder block and gearbox housing need to be checked for shrinkage holes and inclusions to avoid oil leakage or insufficient structural strength; The shell of the new energy vehicle battery pack and the motor end cover must have no defects that affect sealing to ensure battery safety; Lightweight aluminum alloy castings, such as door frames, require identification of air holes generated by die-casting to meet the weight reduction needs of automobiles.
The aerospace industry has very high requirements for detection accuracy. Engine components such as turbine blades and combustion chambers need to accurately identify tiny cracks and inclusions at the 0.1mm level to cope with high temperature and high pressure conditions; Aerospace components such as rocket engine nozzles and satellite mounts need to be inspected for welding defects and internal holes to ensure reliable operation in extreme environments.
In the rail transit industry, the casing of high-speed rail traction motors and gearbox housings need to be inspected for bearing installation shrinkage holes to prevent increased wear and tear; The bogie frame and brake disc should be free of cracks and looseness to avoid structural failure during driving and adapt to long-term vibration and impact conditions.
In the field of construction machinery, thick walled cast steel parts such as excavator arm and crane boom need to penetrate the thick wall to identify shrinkage and large-sized air holes to ensure load-bearing capacity; The hydraulic pump housing and cylinder barrel should have holes that do not affect sealing to prevent hydraulic oil leakage.
In the petrochemical and energy industries, drilling rig drill pipe joints and wellhead equipment need to have no root cracks to avoid underground leaks; The pipeline joints of nuclear power cooling systems must comply with nuclear safety standards and detect minimal defects; The wind turbine hub needs to be checked for internal looseness and adapted for outdoor high load operation.
In addition, the pump valve housing and compressor cylinder body of general machinery also rely on this system to detect defects, which is a key guarantee for the quality of castings in various industries.
