Inspection Equipments
The spectrometer is used to detect the composition of materials, and the computerized automatic display numerical instrument displays and analyzes to determine what kind of elements are contained in the article.
The Capability Maturity Model (CMM) is a methodology used to develop and refine an organization's software development process. The model describes a five-level evolutionary path of increasingly organized and systematically more mature processes.
A universal testing machine (UTM), also known as a universal tester, is used to test the tensile strength and compressive strength of materials.
A roughness tester is used to quickly and accurately determine the surface texture or surface roughness of a material. A roughness tester shows the measured roughness depth (Rz) as well as the mean roughness value (Ra) in micrometers or microns (µm).
The contour tester is an instrument for testing and inspecting the contour of an object. As a precision measuring instrument, it is widely used in automobile manufacturing.
Leak testing is used to determine whether products pass a specified leak limit. Leaks occur when a gas or liquid flows from a higher pressure side to a lower pressure side of a part and are caused by holes, cracks, weak seals or permeable areas in a product.
X-Ray testing is the best nondestructive inspection method for detecting internal defects of castings can be examined to verify the internal structure and integrity of the specimen.The casting absorbs part of the radiation, and the remaining portion of the radiation exposes the radiographic film. Dense material withstands the radiation penetration, so the film is exposed to a lesser degree in those areas, giving the film a lighter appearance. Less dense materials allow more penetration and correlates to darker areas on the film. Any hole, crack or inclusion that is less dense than the casting alloy is revealed as a dark area.
Hardness is a characteristic of a material, not a fundamental physical property. It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation.More simply put, when using a fixed force (load)* and a given indenter, the smaller the indentation, the harder the material. Indentation hardness value is obtained by measuring the depth or the area of the indentation using one of over 12 different test methods.
