 Melting customized raw material according to chemical composition which customer provide.

 2, Spectrum Testing

 We will continue produce after chemical composition approval. 


 3, Cutting Steel 

 Cutting steel into the best proportion for forging.

 4, Annealing

 Annealing for raw material to ensure there is no cracks in products during forging process.

 5, Forging Process  6, Rough machining

 7, Heat Treatment

 We could do different heat treatment ways according to mechanical properties which customer request.

 8, Inspect Mechanical Properties

 We will cut a test specimen from product body to test, and continue producing after test specimen approval.


 9, Machining

 Machining according to drawing dimentions or customer's delivery dimention request.

 10, Magnetic Particle Testing (MT)

 We usually use MT to inspect surface cracks of products.


 11, Ultrasonic Testing (UT)

 We usually use UT to inspect the size of products internal defect, and tell approval or not according to customer's UT grade request. 

 12, Final Inspection

 We will do visual inspection and inspect dimentions of products by measuring inplements after finishing.

 13, Packing   14, Transport
