OEM Custom Service

OEM custom manufacturing and engineering partnership services

Custom Manufacturing Solutions

Matson Foundry provides comprehensive OEM custom casting services, from initial design consultation through mass production and packaging. We work as an extension of your engineering team, providing expert guidance on material selection, casting design optimization, and cost reduction. Our one-stop model takes your project from drawing review to finished components, so procurement and engineering teams can manage one accountable supplier instead of coordinating multiple vendors. During DFM review, we evaluate wall thickness transitions, gating strategy, machining allowance, and tolerance feasibility to reduce risk before tooling starts. We then support prototype validation, pilot production, and full-scale supply with the same process documentation, ensuring smooth transfer from sample approval to long-term OEM production.

Investment casting production from RFQ through prototyping and mass production

OEM Process Flow

Our structured OEM process ensures clear communication, predictable timelines, and consistent quality from RFQ to delivery. Every project follows a defined control plan, with milestone reviews between your team and our engineering, quality, and production departments. This approach helps OEM buyers avoid late-stage redesigns and keeps launch schedules stable when moving from prototype to regular supply.

Step 1: RFQ review & technical feasibility - we review drawings, required certifications, and volume forecasts, then confirm process capability and key risks within the quoting stage.
Step 2: Quotation with material/process recommendation - our team compares alloy options, casting routes, and machining scope to deliver a costed quote with lead-time assumptions and tooling notes.
Step 3: Tooling and sample order with first article inspection - pattern making is developed with CAD/CAM programming and process simulation, followed by controlled sample builds and dimensional validation.
Step 4: Customer approval (FAI report) - we submit FAI documentation, material reports, and sample photos for your engineering sign-off before production release.
Step 5: Mass production with SPC monitoring - critical dimensions and process windows are tracked through SPC to maintain repeatability lot after lot.
Step 6: Final inspection & packing per customer spec - inspection includes CMM checks for key features, visual review, and custom packing labels to match your receiving standards.
Step 7: Shipping (FOB, CIF, DDP available) - export documentation, test reports, and shipment coordination are prepared to support reliable global delivery.

Finished industrial cast components with heat treatment, surface finish, and assembly options

Value-Added Services

Beyond casting and machining, we offer a range of value-added services to deliver fully finished components ready for your assembly line. We are not only a foundry supplier; we are a complete manufacturing solution provider for OEM programs that require dependable quality and supply continuity. By integrating secondary operations into one workflow, we reduce handoff delays, simplify quality accountability, and help customers lower total landed cost. Your team receives one coordinated production plan instead of managing separate vendors for each downstream process.

Heat treatment (solution, aging, normalizing, Q&T)
Surface treatment (polishing, passivation, painting, plating, hot-dip galvanizing)
Assembly of multi-component parts
Custom packaging and labeling
Material certification and test reports (EN 10204 3.1)

With post-processing performed under one quality system, dimensional integrity and surface performance are controlled from casting through final shipment. This integrated model is especially valuable for OEM custom casting services that need heat treatment, corrosion protection, and light assembly before installation at your facility.

OEM custom pump casting components for industrial applications

OEM Custom Casting Applications by Industry

Custom casting is essential for OEMs that need proprietary components designed to their exact specifications - parts that are not available off the shelf. Our OEM custom service supports a wide range of industries:

Pump & valve OEMs - custom volutes, impellers, valve bodies, bonnets, and flanges produced to proprietary designs with customer-owned patterns or we develop patterns from your samples
Hydraulics & pneumatics - manifold blocks, cylinders, and ports that require specific port threading (NPT/BSP), sealing surfaces, and internal passage geometry
Oil & gas equipment - API 6A / 6D compliant components for wellhead, Christmas tree, and pipeline applications, with full material traceability and NDT reports
Water & wastewater - corrosion-resistant castings in duplex stainless steel, nickel alloys, and specially formulated bronze for pumps and treatment equipment
General industrial machinery - housings, brackets, gear blanks, and structural components where proprietary design and reliable repeatability are critical

We treat each OEM project as a partnership - your intellectual property is protected under NDA, and patterns are stored and maintained at our facility with your brand markings applied per specification. Learn how we prevent quality issues across custom casting runs.

Why Choose Matson for OEM Custom Services

Choosing an OEM casting partner is a long-term decision. Here is why OEMs across multiple industries choose to work with Matson:

Engineering-led approach - our team reviews your design for castability before quoting, identifying potential issues like sharp corners, uneven wall sections, and core complexity that could affect yield and cost
Pattern ownership flexibility - use your existing patterns, have us build new ones from your samples or CAD, or co-develop patterns for proprietary designs with shared IP terms
End-to-end capability - investment casting, heat treatment, CNC machining, surface finishing, assembly, and testing under one roof, reducing supplier management overhead
Scalable production - prototype (1-50 pcs), pilot run (50-500 pcs), and full production (500-10,000+ pcs/year) with consistent process control
Responsive communication - dedicated project manager for each OEM account, with regular status updates, inspection reports, and shipping documentation

Your proprietary design deserves a partner who treats it with the same care you would - from the first DFM review to the final shipping crate. Contact our OEM team to discuss your project.

Frequently Asked Questions About OEM Custom Casting Services

What does end-to-end OEM service include?

Our end-to-end OEM service covers the complete supply chain: design for manufacturing (DFM) review, tooling design and fabrication, prototype casting, production, CNC finishing, surface treatment (passivation, painting, coating), inspection, packaging, and logistics.

Can you help with design optimization before tooling is made?

Absolutely. Our engineering team provides a free DFM review at the quotation stage. We identify potential casting issues - thin sections, sharp corners, undercuts - and suggest design improvements that reduce cost and improve yield before any tooling is ordered.

How does tooling cost amortization work?

For long-running programs, we can structure the tooling cost as an upfront investment or amortize it across the first production order. We work with OEM buyers to find a cost structure that matches their budget and production timeline.

What industries do you support for OEM custom casting?

We serve OEM buyers in valve and pump manufacturing, automotive (OEM tier 1 and tier 2), oil & gas equipment, water infrastructure, chemical processing machinery, and general industrial equipment.
