Die casting is an important basic industry for a country. With the high-speed development of the technology, the die casting industry is facing more and more challenges.

Because of the high standards on Safety, Environment Protection, Human Resource and customized demand, it’s urgent for die casting factories to raise the quality and production efficiency and cut down the power consumption and wasting.

It’s complicated processing on die casting. There’re many reasons to cause the flaws. I.e. impure raw materials, imperfect production process, unreasonable mold structure design, improper production operation. The common flaws on die casting are crack, porosity & void, shrinkage and scab. For saving costs and offering the high quality products, it’s necessary to detect the flaws at the processing beginning.

The X-Ray NDT technology has been the first choice on the die casting flaw inspection because of low cost, high efficiency, wide area application, clean and real-time images, etc.

Flaw Sample 1：Crack

The cracks are mainly caused by the improper structure design and unqualified production process.

There're tow cracking types: Casting crack and Heat treatment crack.

The light color mark as showing on the X-Ray image is the crack.

Flaw Sample 2：Porosity/Void

The Void/Porosity are mainly caused by the failure ventilation on the die casting processing.

The surface Void/Porosity can be found by blast cleaning. But it only has to be found the internal Voids/Porosity through X-Ray.

The most flaws in the Aluminum die castings are Void/Porosity.

Flaw Sample 3：Shrinkage

The Shrinkage are mainly caused by the improper structure design.

And the shrinkage flaws are often visible on the joints in inner runners, the thick part of the feeder and the large thickness areas.

The serious flaws are showing with filiform image and the light flaws are showing with light color smoke image.

Flaw Sample 4：Scab

The scab are mainly caused by the impurity raw materials or there're

other materials mixed in the raw materials.

They're often on the upper surface of the aluminum die casting parts and the in-ventilation parts.

The scab are showing with dark block on the X-Ray image.
