HG Precision Components is by rigorous process design, then approval by engineer management, to manufacture, and full check, shipment arrangement.

The order flow chart is:

1. order& drawings receive from customer

2. process design

3.process design approval

4.manfuacture arrangement

5. full check

6. shipment arrange

Here is take an example for the process design.

Process Design	time	process detail
preparing material		Raw Material size is: ∮125*45mm
fast wire cutting		∮70 dimension rough process, -/+1mm obligate
CNC	4h	Ex-circle is -/+0.02mm tolerance to prepare, bore is -/+0.15mm obligate, the two side concentricity is 0.03mm, thickness is -/+0.2mm, and in this process, we make sure the roundness finish, R core is smoothly connection. The bench work is necessary.
process inspect	1h	Check the outline dimension, and the surface finish, the and bore dimension
heat treatment		HRC60-/+1
IQC	0.5h	Check the hardness
surface grinding		After the grinding flatness within 0.01mm
CNC	3h	the face of ex-circle∮80&∮70 through hole, and the back∮80 the right size, the concentricity is within 0.01mm, also do the bench work
full check	1h	Check the main size: ex-circle, bore, and ∮80 concentricity, and official inspection report.
