Material Identification And Quality Assurance
At Star Rapid, 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 Star Rapid, 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)
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.
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.
There are many thousands of available plastic resins to choose from when making plastic injection molded parts. In order to ensure that the resin we use is of exactly the right kind, we’ve invested in a PolyMax analyzing gun. This device uses a beam of laser light to bounce off the surface of a test sample and read the unique signature given off by its molecular vibration. It contains a database of hundreds of plastic types in memory, and can be programmed with additional plastic types whenever the need arises. Just one more way we’re staying ahead of the competition to give you exactly the right material every time. And check out our blog to read more about how the PolyMax gun works.
Coordinate Measuring Machine
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 machine (CMM) 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.
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.
