Finished titanium and zirconium components manufactured from forgings sourced through qualified supply partners and machined to customer drawings and specifications.
An alternative to casting for suitable component geometries and a complementary supply route for pump and valve internals.
Forged starting material can serve either as an alternative to a casting or as a complementary source for internal pump and valve components. The appropriate route depends on component geometry, quantity, material utilization, machining scope and total manufacturing cost.
Pump and Valve Internal Components
Pump and valve assemblies often combine cast pressure‑containing components with forged and machined internal parts. In addition to cast bodies, casings and impellers, ALBA can support the supply of finished internal components manufactured from qualified forged starting material.
For some component geometries, producing the part from a forging and completing the final shape by machining can result in a lower total manufacturing cost than casting. This may apply where the geometry is relatively straightforward, a suitable forged starting form is available and the required quantity does not justify casting tooling or process preparation.
Selection factors:
Casting and forging are not interchangeable in every application. ALBA reviews the component drawing, required material grade, geometry, quantity, machining scope, inspection requirements and delivery condition before assessing the available manufacturing routes.
| Project consideration | Casting route | Forging + machining route |
|---|---|---|
| Component geometry | Suitable for complex near‑net shapes and integrated features | Suitable where the component can be efficiently machined from an available forged form |
| Starting form | Cast close to the required component geometry | Forged bar, ring, disc or shaped blank |
| Tooling/process preparation | Depends on casting process and quantity | Depends on forging availability and any required forging tooling |
| Machining requirement | Local or extensive machining according to design | Normally a greater portion of the final geometry is produced by machining |
| Typical role | Bodies, casings, impellers and complex flow components | Stems, shafts, wear rings, sleeves and similar components |
| Economic selection | Project‑specific | May offer lower total cost for suitable geometries and quantities |
Final manufacturing‑route selection is based on the complete drawing and project requirements. Neither route is inherently more economical for every component.
The material grade, applicable specification, forged starting form, heat‑treatment condition, testing scope and documentation requirements are defined before purchase.
Raw forgings are sourced from qualified forging shops selected according to the material, grades, product form and project requirements.
Material identification, dimensions, certificates and required test results are reviewed before the component enters subsequent machining.
The forging is machined to the customer drawing and inspected according to the specified dimensional, surface and documentation requirements.
Quality Control includes：
Send us your component drawing, material grade, required quantity and inspection requirements. We can review whether the part is better suited to a casting or to a forged and machined starting form.
