Precision castings in aluminum, steel, iron and copper alloys. From prototype to mass production, we deliver quality you can rely on.
From high-volume die casting to precision investment casting — we match the right process to your product requirements.
Aluminum alloys are lightweight yet deliver high dimensional accuracy for complex geometries and thin walls, ideal for high-volume production runs.
Also known as Permanent Mould casting, this process is ideal for aluminum and zinc alloys requiring excellent surface finish and mechanical properties.
Versatile process supporting cast iron, aluminum, brass, and steel. Our in-house foundry is particularly strong in cast iron sand casting.
Our core specialty for stainless steel castings — competitive pricing, consistent quality, and fast lead times for complex, near-net-shape parts.
Using the silicon gel process with green wax and quartz sand, this method produces exceptionally smooth surface finishes and tight dimensional tolerances.
A comprehensive range of forged shapes and components, manufactured using open-die forging hammers for superior strength and material integrity.
Five clear steps from RFQ to delivery — with full transparency and quality ownership at every stage.
Send your drawings (2D/3D), material specs, and target quantity to RFQ@renyicastings.com
Our engineers review design for manufacturability and suggest process optimizations
We produce tooling and first-article samples for your approval before mass production
Full-scale production with in-process QC inspections at every critical stage
On-time delivery with full dimensional reports, material certs, and after-sales support
Renyi Castings is committed to providing comprehensive casting services for the diverse needs of global clients. We supply everything from raw castings to fully finished, machined components — all under one roof.
We use tried-and-tested casting processes and perform all secondary machining and quality control operations in-house. Our aluminum die casting and sand casting joint-venture foundries ensure capacity and flexibility.
Every casting leaves our facility with full traceability — from incoming material verification to outgoing dimensional sign-off. Quality is built into the process, not inspected in after the fact.
Our quality management system is independently audited and certified to ISO 9001, ensuring consistent processes from order entry through final shipment.
Verified & CurrentEvery heat charge is verified by OES spectrometer analysis before pouring. Mill certificates are cross-checked against customer specifications.
CNC coordinate measuring machines check 3D geometry and GD&T callouts. Vision Measuring System handles micro-features and 2D profiles.
X-ray inspection detects internal porosity, shrinkage and inclusions. Applied to 100% of structurally critical castings on request.
Material test report, dimensional inspection record, and NDT results provided as standard with every delivery. No extra charge.
Trusted by manufacturers across ten major industries worldwide.
