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.

How to safely machine magnesium?


Although it might sound daunting, it is perfectly safe to CNC machine magnesium if the right precautions are taken.

Avoid tight clearance angles

Although magnesium can be machined at fast speeds without compromising the quality of the part,

it is best to avoid tight clearance angles, because contact between the tool and workpiece increases friction and cutting temperature.

Maintain proper tool condition


Sharp cutting tools can reduce the fire hazard of machining magnesium.
Dull tools can rub and cause friction, which causes sparks and builds up heat where the sensitive magnesium chips

are being created. Needless to say, sharp tools will also produce better parts.
Most machinists use a carbide cutting tool with a large relief angle for machining magnesium.

Avoid water-based coolant

Although coolants reduce machining temperatures, a water-based coolant can actually increase the risk of a magnesium fire

as it will produce hydrogen gas.Avoid coolant altogether, or use a light mineral oil in place of standard coolant. Compressed air

or argon gas can also be used to reduce temperatures without the risk of exacerbating a potential fire.


Make discontinuous chips

When CNC machining magnesium, it is better to make well-broken discontinuous chips, as opposed to more easily ignitable ribbon chips.
Use only explosion-proof chip vacuum
If using a vacuum extraction system for chip removal, this system should be as fireproof as the rest of the machining setup.

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).
