Due to widespread materials non-conformance in China, Star Prototype takes Positive Material Identification (PMI) very seriously. We are determined to ensure that our customers' quality requirements are met. To meet this goal, we have invested heavily in our inspection department, acquiring several different metallurgical testing machines for prototype materials testing. The majority of our machines are portable, so if you have any inspection needs, contact us to discuss how we can be of service to you.
View the video tour of our inspection technologies to see for yourself how Star Prototype is ensuring material quality.
Optical Emission Spectrometer (OES)
Positive Material Identification (PMI) is a daily problem in China. One of our most recent investments, an Optical Emission Spectrometer (OES) is used to positively identify metals. With this equipment, we can, without any doubt, guarantee that the materials that we use are what they are supposed to be. The engineers out there may know that there is a huge difference between different grades of aluminum, for example, but how can you know for sure which grade is used for your prototype? Without materials testing using OES or possibly XRF, the simple answer is you can't.
testing can have disastrous consequences. If a customer specifies a part
to be made from Aluminum 7075, then the chances are that this part is going to
be subjected to some load. If the part is made from a lower grade of aluminum
it could well fail, causing an untold amount of damage. It has happened before,
and it will happen again, but not to Star Prototype. Our OES machine is state-of-the-art
and was purchased from Oxford Instruments, along with the entire range of
calibrations. This means that we can positively identify aluminum, steel, copper,
brass, zinc, nickel, titanium, and more. Additionally, our unit is portable, so
we are able to offer prototype
materials testing as a service to anybody needing PMI (Positive Material
Identification) in the Guangdong Province. We are proud to be able to satisfy
ourselves and our customers that the metals we supply conform to the
specifications ordered. PMI is a very rare service among Chinese machining
Ultrasonic Hardness Tester
An Optical Emission Spectrometer can positively
identify the composition of the material, but what about the hardness, or
temper of the material? To ensure we know the hardness of a material, we have invested
in an Ultrasonic Hardness tester, designed to check the hardness of a full
range of metals from soft aluminum up to fully hardened tool steels. This tool
is also portable, so we can use it off site when the need arises.
Faro Laser Scanning
Star Prototype also has a Faro laser scanner with touch probe. This is the latest high-precision Faro Quantum Arm and is used to measure virtually any part. Once the part is measured through Faro laser scanning, we can compare the data to the measurements in the 3D CAD file, to check for any deviations or missed features. At Star Prototype, we primarily use our Faro laser scanning arm for first article inspection of injection molded parts and pressure die cast parts. We can also use our Faro laser scanner to check complex stereolithography and SLS master models in the rapid prototyping and vacuum casting process.
also have a touch probe just like on a traditional coordinate-measuring machine
(CMM) that we can use to measure very tightly toleranced features more
equipment is ideally suited to rapid prototyping and tooling because of the
ease of use and flexibility to inspect complex geometries quickly and reliably.
Again, this piece of equipment is portable and can be used to inspect off site
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.

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.
analysis is particularly useful for fast, on-site Positive Material Identification
(PMI) and RoHS testing. Our Oxford Instruments X-Met 7000 XRF analyzer gun is
completely non-destructive and leaves no mark on the surface of the test piece.
Although not as accurate as the OES, it is sufficiently accurate to identify
non-conforming materials. If we find a measurement on the XRF analyzer to be
just outside of specification, we will check the test piece on the OES for a
more accurate analysis.
Materials Testing Case Study
Star Prototype recently assisted an engineer who suspected that his stainless steel was not actually the grade it was supposed to be. With our state-of-the-art metallurgical testing technology, we were able to help him discover this fraud.
