Casting Capabilities In Detail

Stainless Steel Investment Casting

As a stainless steel investment casting manufacturer, Waking runs the silica sol lost wax process for parts that need fine detail, stable dimensions and good as-cast surfaces: valve bodies, pump housings, impellers and food or marine hardware. Complex geometries, thin walls and internal structures that are difficult to machine from solid are cast close to net shape, then finished in-house. Shortlisting an investment casting supplier? Send drawings or samples — custom investment casting projects start from there.

ProcessSilica sol lost wax (investment) casting
MaterialsStainless steel 304 / 316 / CF8 / CF8M
Typical partsValve bodies, pump parts, impellers, machinery components
Secondary workCNC machining, polishing, passivation
DocumentationMaterial certificates & dimensional inspection reports

Carbon & Alloy Steel Casting

As a carbon steel casting supplier and steel casting manufacturer, we produce steel casting parts for industrial machinery, agriculture and construction equipment. As a lost wax casting manufacturer, our investment casting foundry controls mold preparation, melting, pouring, cooling, cleaning and defect checking in-house, with heat treatment arranged per specification — so batch-to-batch consistency holds from sample approval to mass production.

Typical partsMachinery components, structural parts, fittings
Heat treatmentPer material specification
Quality controlProcess control from melt to final inspection

Aluminum Low Pressure & Gravity Casting

For aluminum components, Waking runs both low pressure casting — dense, leak-tight parts such as motor housings — and gravity die casting for cost-effective medium and large components. Tooling, casting, T-slot machining and surface finishing (sand blasting, anodizing, powder coating) are coordinated in one plant, with leak testing available for pressure-containing parts.

Typical partsMotor housings, transmission housings, brackets
FinishingSand blasting, anodizing, powder coating
TestingLeak testing for pressure-containing castings

CNC Machining of Castings

Castings rarely ship as-cast. Our precision casting factory finishes them on 400+ CNC machines — milling, turning, drilling, tapping — using casting-specific fixtures and datum strategies so machined surfaces, threads and assembly faces hit drawing tolerances. Key dimensions are verified on CMM, with X-ray, hardness and metallurgical testing available in our inspection lab.

ApproachCasting-specific fixtures & datum design
InspectionCMM, X-ray, hardness, metallurgical analysis
ReportsDimensional & material reports per order
ScopeOne-stop: casting + machining + inspection

Every quote covers the full chain — casting process, machining plan, inspection method and export packaging — so you deal with one steel casting manufacturer instead of coordinating a foundry, a machine shop and an inspection house.

Waking has been casting and machining metal components since 2002. Foundry, CNC workshop and inspection lab share one 70,000 m² site, so process questions get answered by the people running the equipment — not relayed through a middleman. Drawings are reviewed before production, critical steps are controlled during it, and finished parts ship with the reports your QA team needs, to 40+ export markets.

IATF 16949 quality management, environmental and occupational health & safety management certificates.
