Cast Steel Equipment Support Casting | OEM Foundry & Machining Services
Heavy equipment demands rigid, vibration-absorbing structural foundations. Our cast steel equipment support castings are engineered for heavy industrial machinery operating under severe static and dynamic loads. Produced via sand casting and precision-machined to tight tolerances, these components provide exact alignment and structural integrity for gearboxes, drive assemblies, and processing equipment.
Primary Function: Load-bearing, mechanical alignment, and vibration dampening for heavy machinery.
Manufacturing Route: Pattern making → Sand molding → Pouring → Heat treatment → Rough/Fine machining → NDT inspection.
Customization: Built strictly to customer engineering drawings and 3D CAD files (STEP/IGES).

Material & Process
Material selection dictates structural reliability under cyclic fatigue and impact loads. We cast standard carbon steels, alloy steels, and wear-resistant grades tailored to operational environments.
Common Material Grades:
- ASTM A27 / A216 (WCB / WCC): General structural and pressure-containing carbon steel.
- ASTM A148 (80-50 / 105-85): High-strength alloy steel for severe mechanical stress.
- DIN / EN GP240GH (1.0619) / G20Mn5 (1.6220): European standard engineering steel grades.
- Melting & Pouring Facilities: Induction furnaces with direct spectrometer chemical composition analysis prior to pouring.
- Thermal Treatment (In-House): Full-furnace capability for Normalizing, Annealing, Quenching, and Tempering to relieve residual stress and optimize grain structure and hardness.
Machining & Finishing
Raw castings require precise secondary processing to ensure proper assembly fit. Our in-house machine shop eliminates tolerance accumulation between the foundry and final assembly.
Machining Equipment: CNC horizontal boring mills, large-scale CNC vertical machining centers, and heavy-duty floor-type milling machines.
Critical Operations: Face milling of base mounting pads, precision boring of bearing housing bores, and drilling/tapping of anchor bolt patterns.
Surface Preparation: Shot blasting for scale removal, followed by industrial primer coating or rust-preventative oil application based on transit requirements.
Quality Control
Internal soundness is verified through rigorous non-destructive testing (NDT) performed by ASNT Level II certified technicians.
Dimensional Verification: CMM (Coordinate Measuring Machine) for complex geometries and laser trackers for large structural parts.
Non-Destructive Testing (NDT):
- UT (Ultrasonic Testing): Internal defect detection for critical load-bearing sections (ASTM A609).
- MT (Magnetic Particle Testing): Surface and near-surface crack detection (ASTM E709).
- PT (Penetrant Testing): Surface discontinuity inspection.
- Destructive Testing (On Request): Tensile test bars cast with the heat; Charpy V-notch impact testing at specified temperatures (-20°C to room temp).
Applications

OEM / Customization
We operate strictly as an OEM contract manufacturer.
Engineering Support: DFM (Design for Manufacturability) review on customer drawings to optimize draft angles, minimize hot spots, and reduce gating/riser waste.
Prototyping: 3D printed sand molds available for rapid prototype validation before committing to permanent metal tooling.
Documentation: Complete PPAP (Production Part Approval Process) packages, dimensional inspection reports, and material certificates delivered with every shipment.

FAQ
Q: What is your standard lead time for custom support castings?
A: Tooling and sample production typically require 35 to 45 days. Mass production batch delivery runs 30 to 50 days depending on foundry schedule and heat treatment requirements.
Q: Can you provide third-party inspection reports (TPI)?
A: Yes. We routinely accommodate inspections by independent agencies such as SGS, Bureau Veritas, or TÜV prior to final packaging.
Q: How do you prevent shrinkage and internal voids in heavy sections?
A: We utilize computer-aided casting simulation software (SolidCast/ProCAST) prior to pattern making to design optimal gating, risering, and chills, ensuring directional solidification.
Q: What file formats do you accept for quotation and manufacturing?
A: We accept 3D models in STEP, IGES, XT, and Parasolid formats, alongside 2D manufacturing drawings in PDF or AutoCAD DWG format.
Q: Do you supply material test reports with the shipment?
A: Yes. Every shipment includes an EN 10204 3.1 Certified Material Test Report detailing actual chemical composition and mechanical test results for the specific heat number.
Q: What is the maximum single-piece weight your foundry can handle?
A: Our pouring capacity handles single-piece steel castings up to 5,000 kg (net finished weight).
