2. Investment casting (1) Chinese investment (2) Japanese loss wax
Frequently used materials include carbon steel(GS45,GS52,GS60), alloy steel(16Mn,25Mn,34CrMo,42CrMo4) and stainless steel (CF8, CF8M, CF3, CF3M). Product limitation up to 80 kg and external dimension up to 700 mm. JIT delivery benefits a lot from CNC machined tooling also from automation on process like wax injection, tooling cooling, and shell making.
1) molding process:
Chinese Loss wax investment casting/Japanese Loss Wax investment casting
(3) Fast Forming/Rapid Prototyping/RP investment casting Technique normally used on the condition of very narrow lead time for samples or project under Prototyping step, Since there is no need for moulding, then from general cost side, also economical
3. Centrifugal casting
Material available in stainless steel, Hi-Ni alloy and Hi-Cr alloy. Inspection includes UT/X-ray/PT/Eddy/dynamic balancing and Spectrometer for chemical composition. Boring and grinding machining services are optional upon request, the roughness for inner hole of N7 grade. Customized products include CF8M stainless steel pipe with OD700/L4500mm, and ethylene cracking furnace tube.
