Rapid Prototype Inspection

Material Identification and Quality Assurance

for rapid prototypes

Tuowei prototype sophisticated measuring and testing equipment in-house to qualify all incoming raw materials and rapid prototypes,

while our modern metrology lab ensures that your parts meet your exact specifications.

Quality rapid prototypes Inspection and Testing

Making a product of consistently high quality requires good management and process control techniques combined with advanced equipment.

At Tuowei, we make sure every project includes these steps for quality assurance:


Design for Manufacturing (DFM) technical review of all requests for quotation (RFQs)


Contract review upon receipt of P.O


Incoming materials inspection


First article and in-process inspection


First article and in-process inspection


Final inspection and testing w/reports and certifications per customer requirements.

We confirm all incoming raw materials using one or more of the following methods:
Coordinate Measuring Machine

A coordinate measuring machine (CMM) is a device for measuring the physical geometrical characteristics of an object. At its most basic a coordinate is a point, a fixed singular location in three-dimensional space. With our Coordinate Measuring Machine (CMM) we analyze 3D parts to compare measurements, positions, shapes, tolerances, and surface curvature with the 3d data. The measuring instrument provides detailed graphic reports of the product quality allowing us to observe any imperfections.


At Tuowei Prototype we understand very well that the color of your finished product can be as important as its function. We offer extensive color matching services using standardized lighting conditions, and we've recently invested in colorimeter to help clients better visualize the finished look of molded plastic parts.

Shore durometer

Hardness may be defined as a material's resistance to permanent indentation.There are several scales of durometer, used for materials with different properties. The two most common scales, using slightly different measurement systems, are the ASTM D2240 type A and type D scales. The A scale is for softer plastics, while the D scale is for harder ones. Tuowei have these 2 kinds of types to ensure the softer and harder plastics are with correct hardness.

Round Plug

For the machined holes, usually clients have very strict requirement about the tolerance. because correct hole can make sure the assembly correct. Tuowei prototype put the round plug with different grade in the holes, if the plug is suitable for the holes, then the tolerance is ok, if the plug can't be put in and much smaller than the hole, then the tolerance is incorrect. this is a very easy way to test and make a correct hole, and the tooll is also portable for greater convenience for our clients.
