Production service process
 
We have three rought parts production lines: resin sand casting,centrifugal casting and forge line.
 
Sand Casting Process
 
Firstly, according to customer drawing, our engineer design casting drawing.
1)  Material & Mold
Molding materials preparation:
Molding sand, core sand, furan resin, water and etc
Mold/pattern preparation: wooden or metal material
Make the mold shape: manual molding for large parts and machining molding for small.
Mixing the sand, furan resin and other auxiliary materials- making core-paint and assembly the mold, sand frame, and the core and press to tight-drawing the mould, paint and dry the mold shape
2)  Melting & Pouring: intermediate frequency electric furnaces
Make pilot bar- test chemical composite- if ok, continue the melting
Pouring and melting temperature test
3)  Mould assembling & Open boxes
Clean the cast and remove the casting head
4)  Grind &Polishing
Clean, sand-blasting
5)  Testing Items
Check the size to the original drawing
Mechanical test and ultrasonic flaw detection, metallographic detection (if customer require) Final check according to the drawings
6)   Put Casting Goods in storage
Surface treatment options: polishing, sand blasting, heat treatment, paint, power coating, anodizing, electroplating, mirror polishing
Precision machining options: CNC, milling, drilling, numerical lathe, peel, polishing and etc
7)   Packing & Delivery
Standard export package (Wooden Case/Bulk/OEM As Request)
Accept FOB, FAS, CNF, CIF door to door etc or customer designated shipping agent.
 
Centrifugal casting process:
 
Precision machining metal mould according to customers’ products.
Other steps, melting, pouring, opening, clean, tempering similar to sand casting.
 
Steel forging process:
 
Forging– Normalizing & Tempering – Proof Machining- Quenching & Tempering – Finish Machining
