Magnetic Particle Inspection In the Detection of Internal Defects in Castings

Magnetic particle inspection is a non-destructive testing method that detects defects on the surface or near the surface of ferromagnetic materials by the accumulation of magnetic particles in the leakage magnetic field near the defe...

Ultrasonic Flaw Testing of Metal Castings

Ultrasonic testing refers to a method of injecting ultrasound (high frequency and short wavelength) into the casting, and then detecting the internal defects of the casting according to the characteristics of its refraction and waveform...

Silica Sol Shell Making Process

In the lost wax casting process, the making of the mold shell is a key process. Casting shells made of silica sol as a binder can obtain good surface and high dimensional accuracy for castings.

Centrifugal Pump Impellers

The impeller refers to a rotating body with blades that transmits energy to the liquid, and can also refer to the general term for the wheel disc and the rotating blades installed on it.

Alkali Metal Explosion to Clean Metal Castings

The alkali metal explosion cleaning process, also known as high temperature alkali metal explosion, its basic working principle is: put the casting into a caustic soda solution with a temperature of 750-800℃ and a mass concentrati...
