Quality Inspection


  • In addition to our stringent in-process controls, all components must pass a thorough final inspection.

we have a coordinate measuring machine, salt spray testing machines, profile projectors and other precision

measuring devices, etc.


  • Customers' CAD drawings can be directly imported in the coordinate measuring machines (CMM) for a

direct comparison to the dimensions that are taken from the physical part.


  • All testing is conducted in a 20 degree Celsius climate-controlled inspection room and the CMM is calibrated to

GB/T 16857.2-2006 (ISO10360-2:2001) standards. All components and sub-assemblies are 100% inspected,

identified with a logo if required and a final inspection is generated pertaining to all the critical dimensions.

1-Is magnesium hard to machine?

  • Drilling, milling, turning, and other processes are smoother when using magnesium, and machining the material requires a significantly lower cutting force and overall production time than other metals.

2-Can you CNC magnesium?

  • Magnesium is a lightweight metal with high level of machining ability that can be CNC machined to create parts with high strength and excellent corrosion resistance. However, magnesium can be difficult to machine due to its tendency to ignite or explode if proper precautions are not taken


3-How many machines do you have?

  • We currently have more than 60 machines: roughly 40+ CNC mills and 30 Injection mold machine,10+ 3D printers. With our long history of growth, this number is always changing.


4-How do I get a quote?

  • To get a quote for all of our services, simply send us your 3D CAD model to us. You'll get an interactive quote within hours with free design feedback. If there are problem areas in the submitted design,we will provide free design feedback(DFM).

5-What types of files do you accept?

  • We can accept native SolidWorks or ProE files as well as solid 3D CAD models from other CAD systems output in IGES (.igs), STEP (.stp), ACIS (.sat) or Parasolid (.x_t or .x_b) format.

6-Do you provide First Article of Inspection (FAI) Service?

  • We can provide FAI as part of the unlimited offer.



7-What is payment term does your company can be acceptable?

  • We can accept T/T (50 prepayment should be paid before start the production; the 50% remaining payment should be paid after finish the project).
