3. Longxin Poduction Process for Spheroidal Graphite Casting :
Sand casting/centrifugal casting/Forging– Normalizing & tempering – Rough machining-Precision machining- Quenching & Tempering – Finish Machining-Finish treatment-Package and deliver
Process
Firstly, according to customer drawing, our engineer design casting drawing.
1) Material & Mold
==Mold/pattern preparation: carbon steel or other cast steel
Make the mold shape: high precision machining
2) Melting & Pouring: intermediate frequency electric furnace,5 sets, 5000Tons melting capacity.
==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, me-tallographic 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.
