Precision & Steel Castings
Sand casting, lost-foam casting, and investment casting support for pump bodies, valve bodies, counterweights, and complex industrial components.

How this manufacturing scope is defined
Custom casting starts with process selection. Part mass, wall transitions, internal passages, required surface, tolerance, alloy, annual quantity, tooling budget, machining stock, and inspection determine whether sand casting, lost foam, investment casting, or another route is appropriate.
The quotation should separate tooling, casting, heat treatment, rough and finish machining, NDT, dimensional inspection, coating, and documentation. This makes first-article approval and repeat purchasing easier to control.

Manufacturing scope
Processes and component families
Pump & Valve Body Castings
Cast housings and pressure-containing geometries reviewed against drawing, material, and inspection requirements.
Equipment Counterweights
Cast iron and cast steel counterweights for construction, lifting, and material-handling equipment.
Complex Structural Castings
Non-standard cast parts with pattern, machining, heat-treatment, and dimensional planning.
Technical definition
Casting route and drawing review
Define the geometry, material, quantity, and acceptance requirements before fixing the foundry process.
| Review area | Manufacturing guidance | RFQ input |
|---|---|---|
| Geometry and wall transition | Review feeding, shrinkage, cores, draft, parting, distortion, and machining access. | 3D model, section views, critical wall thickness |
| Material and heat treatment | State the full grade, standard, mechanical-property condition, weld repair rule, and allowed equivalent. | Material specification and required test values |
| Casting tolerance | Separate as-cast dimensions from machined datums and identify critical-to-function features. | Datum scheme, tolerance standard, machining allowance |
| Inspection level | Select NDT type, extent, locations, acceptance criteria, first article, and dimensional reporting. | Inspection plan and acceptance standard |
Production sequence
A controlled route from RFQ to release
- 01
Process review
Compare casting routes against geometry, alloy, quantity, tolerance, and tooling.
- 02
Tooling and simulation
Develop pattern, core, gating, feeding, and distortion controls where applicable.
- 03
Cast and condition
Melt, pour, clean, heat treat, and prepare machining datums.
- 04
Machine and release
Finish critical features, inspect, document, preserve, and pack.

Inspection and documentation
Release points to include in the order
- Q1Material heat and test-sample traceability

Frequently Asked Questions
What should I include in a precision & steel castings RFQ?+
Include the controlled drawing and revision, material grade, quantity, critical dimensions and tolerances, process or heat-treatment requirements, inspection and documentation scope, destination, and required delivery date.
Can you review an existing component sample?+
A suitable sample can support dimensional capture and process planning. The buyer should also provide operating context, required material, acceptance criteria, and any dimensions that cannot be reliably recovered from a worn part.
How are inspection and certification requirements handled?+
State every required certificate, test, NDT method, dimensional report, witness point, marking, and packing requirement in the RFQ. The quotation should identify what is included, what is optional, and any open assumptions.
