Description

Technical Parameters

Product Overview

Complex geometry: intricate internal passages, thin walls, near-net-shape features difficult to achieve by forging or fabrication
Process flow: wax pattern → ceramic shell → cast in the specified alloy → heat treatment → precision CNC machining of critical features
Surface quality: smooth as-cast finish, reduced material waste
Cost benefit: dimensional accuracy that shortens or eliminates downstream machining on non-critical surfaces
Best suited for: OEMs replacing forged or fabricated designs with a lighter, lower-cost lost wax casting parts solution that still meets pressure, load, or fatigue requirements

Materials

Material Grade	Grade	Typical Properties	Common Use Case
Carbon steel	WCB	Good strength and weldability, moderate cost	General industrial parts, valve bodies, pump housings in non-corrosive service
Carbon steel	20#	Low carbon, good ductility, easy to machine	Structural brackets, low-stress components
Carbon steel	45#	Medium carbon, higher strength than 20#	Shafts, gears, load-bearing structural parts
Alloy steel	42CrMo	High strength and toughness, hardenable by heat treatment	High-load gearbox, drivetrain, and heavy machinery components
Stainless steel	304	Good general corrosion resistance, non-magnetic	Food-grade fittings, general corrosive-environment parts
Stainless steel	316	Improved corrosion resistance over 304, chloride resistant	Marine hardware, chemical processing parts
Stainless steel	316L	Low-carbon version of 316, reduced weld-decay risk	Welded assemblies, pharmaceutical and food processing equipment
Stainless steel	CF8M	Cast equivalent of 316, good high-temperature strength	Pump and valve bodies in corrosive or high-temperature service

Material is selected based on the pumped or handled medium, load, operating temperature, and corrosion exposure of your application. Our engineers can recommend a grade or qualify an alternative alloy based on your specification.

Technical Specification

Item	Specification
Manufacturing process	Water glass or silica sol lost wax casting → heat treatment → CNC turning/milling/drilling → surface finishing → inspection
Casting tolerance	±0.2mm
Machining tolerance	±0.02–0.05mm on critical features
Surface roughness	Ra 3.2–6.3μm as cast; Ra 1.6μm or better after machining
Critical features	Threads, bores, and mating faces held to drawing specification
Applications	Valve bodies, pump housings, agricultural machinery components, automotive brackets, marine hardware, hydraulic fittings, general OEM structural parts
Industries served	Water treatment, oil & gas, construction machinery, food processing equipment
Customization	Fully manufactured to customer drawing, sample, or reverse-engineered CAD model, material, tolerance, and surface finish per specification

Manufacturing Process

Wax pattern - precision wax tooling built to your drawing
Ceramic shell - pattern shelled in ceramic slurry for dimensional stability
Dewax & casting - shell fired, then cast in the specified alloy
Heat treatment - normalizing, quenching/tempering, or stress relieving as required
CNC machining - bores, flange faces, and threads brought into tolerance
Surface finishing - shot blasting, plating, painting, or coating per specification
Final inspection & packaging - dimensional check, cleaning, export-ready packaging

Because casting and machining both happen in-house, tooling issues found during trial casting are corrected immediately rather than routed through a subcontractor. Before tooling is cut, our engineers also provide a free DFM (Design for Manufacturing) review - typically returned within 48 hours, flagging wall-thickness transitions, shrinkage risk, and parting-line placement that affect castability and cost.

Quality Control

Stage	Check
Material	Spectrometer verification of incoming alloy
Casting	Internal soundness check; PT/UT/X-ray available for pressure- or safety-critical parts
Machining	In-process dimensional checks at each stage
Final inspection	CMM measurement against the original drawing

Documentation

Material certificate
Dimensional inspection report
CMM report
PT / UT / X-ray test report (on request, for critical components)

Packaging

Parts cleaned and rust-protected before packing
Packaging designed to withstand export shipping and handling
