What Is Inspection of Castings?
Foundries and clients inspect castings during manufacturing to identify any hidden defects. Common defects include gas porosity, shrinkage, surface defects, and more. There are different methods for inspecting castings to ensure that manufacturers have finished parts of high quality.
The non-destructive test (NDT) is commonly used to assess the quality of castings without damaging them. Using NDT, you can identify defects that negatively affect the material’s strength. Thanks to non-contact 3D scanning, handheld 3D scanners are capable of measuring castings without causing harm to the parts.
Engineers can significantly save time and costs for inspection by using handheld 3D scanners to measure castings. Read the case study below to learn more about how portable 3D scanner KSCAN-Magic contributes to casting inspection.
3D Measurement Solutions for Industrial Castings
Inspection for Small-to-large Castings
The customer in this case is Sichuan Jinlei Heavy Industries Co., Ltd., a leading foundry in China. It provides high-quality products for industry giants in electric power, petroleum, chemical, machinery, rail transportation, shipbuilding, etc.
The customer used to measure small-scaled castings by lineation, which was inefficient and not precise. They had no efficient inspection methods to inspect large-scale parts. Besides, incorrect measurement results led to insufficient machining allowance.
It means that the part manufactured can be defective or even discarded, resulting in substantial financial losses. Adopting a piece measurement device that is efficient enough is necessary to solve these pain points.
Finally, the customer chose Scantech’s portable 3D scanner KSCAN-Magic to measure the castings, determine the machining allowance, and carry out the full-size measurement on the product to ensure the product quality.
Features of Castings
These small iron castings are about 1.5-2.5 m long, and large castings are 6 m. Some of their machined surfaces are reflective and hard to be scanned.
