5. Longxin Foundry Model Train Parts production service process:

Longxin has 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
