PRECISION CASTING / OEM PRODUCTION
Metal,
made exact.
Investment casting, sand casting and machining for valve, pump and industrial components—built around your drawing.
DRAWING-LED PRODUCTION
A route from drawing to finished component.
Each RFQ is organized around the questions an engineer asks first: process, material, inspection and delivery condition.
Drawing review
Part geometry, material, quantity and critical requirements begin the conversation.
Casting route
Select investment or sand casting according to the component and specification.
Machining & inspection
Define machining state and inspection documents before quotation.
FACTORY RECORD
Seven workshop stages. Three casting routes.
The workshop route follows the actual casting floor: wax injection, wax repair, tree assembly, automatic shell making, dewaxing, pouring and post-processing. RFQs can be routed through low-temperature wax casting, medium-temperature wax casting or sand casting.
Workshop route shown by production stage.
Process route, machining scope and inspection plan are confirmed against each drawing during RFQ review.
CAPABILITIES
Built around the part—not a catalogue.
Investment casting
Silica-sol and composite-process casting for detailed components.
Sand casting
Resin-sand and water-glass routes for larger industrial castings.
CNC machining
Rough and finish-machined delivery options.
Inspection
Inspection planning can include spectrometer material analysis, mechanical testing, magnetic-particle testing (MPI), ultrasonic testing (UT) and radiographic testing (RT).
MATERIAL PASSPORT
Specify the alloy. We define the route.
Renyi’s company profile spans corrosion-resistant, high-alloy and structural steel families. Final grade, heat-treatment condition and test documentation are confirmed against the drawing.
Corrosion-resistant
Duplex & stainless steels
Duplex grades · austenitic stainless steels
For valve, pump and process-equipment castings where corrosion resistance is part of the specification.
High-alloy
Nickel-based & Hastelloy alloys
Nickel-based grades · Hastelloy families
Grade availability and melting route are reviewed project by project before quotation.
Structural
Carbon & alloy steels
Carbon steel · low- and medium-alloy steel
For pressure-bearing and general industrial components supplied raw, rough-machined or finished.
Send the governing ASTM, EN, GOST or JIS designation with the drawing; Renyi will confirm the matching route and documentation in the RFQ review.
RFQ KIT
What makes a casting RFQ ready for review.
Buyers usually receive a faster technical reply when the drawing package, material route and inspection expectations arrive together. Use this checklist before sending proprietary files.
Drawing package
2D drawing, 3D model if available, latest revision, critical dimensions and tolerances.
Material route
Grade, governing ASTM / EN / GOST / JIS standard, heat-treatment state and any corrosion or pressure-service notes.
Demand & delivery
Prototype or production stage, batch quantity, estimated annual use, target delivery and required supply state.
Quality requirements
Material certificate, dimensional report, NDT scope, acceptance criteria and special documentation needs.
What happens after the RFQ.
- Receipt check Sales confirms the contact path and whether the uploaded package can be opened.
- Engineering review The team checks casting process fit, material route, machining state and inspection scope.
- Clarification loop Open drawing, tolerance, NDT or delivery questions are resolved before price is finalized.
- Quotation package The quotation reflects process route, delivery state, document scope and any sampling requirements.
