3. Longxin Poduction Process for  Valve Body 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, 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.

4. Quality Assured:                                                                                                                                              

The QA documents we provide together with the Valve Body Casting :

Factory Quality Warranty bookChemical Composition Report Mechanical Properties Report UT Report Heat Treatment ReportDimensions Check Report

1)The data on chemical composition report and mechanical properties report are approved by third party dominated by customers.

2)100% ultrasonic test according to EN10228-3, SA388, Sep 1921 C/c etc.

3)Heat Treatment Report: provide original copy of heat treatment curve/time table.

4)Steel Ingot: EAF-LF-VD/ESR. Material Certificate according to En10204-3.1 is requested from ingot supplier
