FAQ Trading company or Factory? Factory directly, a sort of trading because to be your one-stop plant needs to cooperate with other plants like foundry,forging factory and others. Main Business? CNC machining, for totally finished your designed parts, will might be involved other business like casting,forging,heat treatments and surface finishing. Quality control? Strictly, inspect in each process, will get into next step only its passed the test. Defeat rate controled within 1.5% even lower. Delivery time? 45-60 days, normally. also rely on the components specification, quantities and other factors. What kind of components you do? It's complicated to say, no matter what it is,as long as your parts can be done throungh cnc machining.We are all in this case. Elements I need to provide? 2D or 3D Drawing,batch quantity,special requirements,net weight for casting or forging parts. Can you do this parts? Why not give us a call for detail ? or email us.
