Material Identification And Quality Assurance

At Kang Ding, we have sophisticated measuring and testing equipment in-house to qualify all incoming raw materials, while our modern metrology lab ensures that your parts meet your exact specifications.

Quality Inspection And Testing

Making products with consistent high-quality requires good process control techniques combined with advanced equipment. At Kang Ding, we make sure every project includes these steps for quality assurance:

    Design for Manufacturing review for all quotes provided
    Contract review upon receipt of PO
    Incoming materials inspection
    First article and in-process inspection
    Final inspection and testing with reports and certifications as required

Advanced Inspection Equipment In-House
Optical Emission Spectrometer (OES)光谱仪(OES)

A testing apparatus that uses a current to electrically charge a sample of the material. The resulting discharge of plasma is unique for each element and this pattern can be read by the optical spectrometer to determine the metal’s complete composition.

There are many similar alloys and grades of metal available on the market, and some of them are mislabeled or fraudulent. We offer Positive Material Identification (PMI) for all incoming materials so you have complete confidence that you receive exactly what you ordered. We are one of the few services in China to offer this level of testing.

XRF Analyzer

X-Ray Fluorescence (XRF) analysis is a non-destructive testing (NDT) process by which materials such as metals, clothes, plastics, ceramics, etc. are exposed to low level, short-wave X-rays or gamma radiation. Each element reflects the emission with a different wavelength and a specially calibrated spectrometer can analyze the wavelengths to detect what elements are present and in what relative concentrations. The XRF analyzer can also detect banned materials under the REACH and RoHS legislation.

Faro Laser Scanning

Ideal for complex geometries, the Faro laser scanner quickly and accurately scans the surface of the part and creates a digital file that can be compared with the customer’s supplied CAD file for easy reference.

We also have a coordinate measuring machine (CMM) with a touch probe for making even more precise measurements of detailed features as required.

Our Mitutoyo Surfometer measures the surface roughness of an item, so we can ensure a specific surface finish is achieved. This device is also portable for greater convenience for our clients.

Coordinate measuring instrumentCoordinate measuring instrument

At its most basic a coordinate is a point, a fixed singular location in three-dimensional space. A series of points can be used to define the parameters of a complex shape. Therefore a Coordinate measuring instrument (CMI) is any device that is able to collect this set of points for a given object and to do so with an acceptable degree of accuracy and repeatability.

The use of contact measurement methods for CNC machining products, stamping products, metal film and other measurements. In order to analyze the machining data of the workpiece, we provide the original information of the workpiece for the customer sample and the reverse engineering. We often need to use the coordinate measuring machine to scan the surface of the workpiece.
