The challenge

The solution

Requirements

• Supplier selection and onboarding checklist for castings and casting assemblies
• 1. Define requirements
• - Part drawings, specs, alloys, tolerances, finishes, and assembly scope
• - Annual volumes, demand variability, target cost, and launch timing
• - Critical quality, safety, and regulatory requirements
• 2. Map sourcing strategy
• - Single vs dual source decision
• - Make/buy and local vs global supply choice
• - Commodity, process, and risk segmentation by part family
• 3. Prequalify suppliers
• - Relevant casting processes and assembly capabilities
• - Material and size range fit
• - Industry experience, references, and customer base
• - Financial stability and long-term viability
• - Capacity, tooling support, and engineering resources
• 4. Evaluate manufacturing capability
• - Process expertise: sand, investment, die, permanent mold, etc.
• - Tooling design and maintenance capability
• - Melt control, heat treatment, machining, and assembly integration
• - Scrap rates, yields, cycle times, and scalability
• 5. Assess quality system
• - ISO or sector-specific certifications
• - APQP/PPAP readiness, FMEA, control plans, and traceability
• - Inspection equipment, CMM, NDT, metallurgical testing
• - Nonconformance, corrective action, and containment process
• 6. Validate commercial offer
• - Piece price, tooling, maintenance, and amortization
• - Material surcharge logic and index linkage
• - Logistics, packaging, duties, and payment terms
• - Cost transparency and should-cost alignment
• 7. Review supply chain resilience
• - Raw material sourcing, foundry inputs, and backup suppliers
• - Capacity redundancy and disaster recovery
• - Lead times, inventory strategy, and freight options
• - Geopolitical, currency, and single-point-of-failure risks
• 8. Check engineering and launch support
• - DFM/DFA input, prototype support, and simulation capability
• - Rapid tooling changes and sample turnaround
• - Change control and engineering revision management
• 9. Audit compliance and sustainability
• - EHS practices, labor compliance, and responsible sourcing
• - Environmental reporting, emissions, and waste management
• - Conflict minerals or customer-specific compliance needs
• 10. Run pilot and qualification
• - Sample evaluation against all specs
• - Process capability targets and first article approval
• - Assembly fit, function, and durability testing
• - Trial shipment and packaging validation
• 11. Negotiate and contract
• - SLAs for quality, delivery, responsiveness, and recovery
• - Warranty, liability, IP, tooling ownership, and confidentiality
• - Change management, pricing review, and termination terms
• 12. Onboard operationally
• - Set up ERP, EDI, forecasts, and ordering process
• - Approve packaging, labeling, routing, and documentation
• - Confirm escalation contacts and issue-management cadence
• - Train on quality requirements and acceptance criteria
• 13. Establish performance management
• - Track PPM, OTD, lead time, cost, and responsiveness
• - Quarterly business reviews and continuous improvement plan
• - Scorecard-based corrective actions and risk re-assessment
• 14. Build long-term strategy
• - Cost reduction roadmap and VA/VE pipeline
• - Capacity expansion and technology road mapping
• - Dual-source qualification and succession planning

Best practices

• 1. Define exact technical specifications, tolerances, and material requirements up front.
• 2. Align casting selection with the end-use application, load, environment, and performance needs.
• 3. Verify supplier foundry capabilities, certifications, and process controls before sourcing.
• 4. Require complete material traceability for raw materials, heat lots, and finished parts.
• 5. Review design-for-manufacturability early to reduce defects, cost, and lead time.
• 6. Standardize inspection and quality acceptance criteria, including dimensional and visual checks.
• 7. Specify testing requirements such as chemical, mechanical, NDT, pressure, or leak testing when needed.
• 8. Evaluate total cost of ownership, not just unit price, including scrap, rework, logistics, and warranty risk.
• 9. Confirm that the supplier can support secondary operations such as machining, coating, heat treatment, and assembly.
• 10. Establish clear change-control procedures for design, process, material, and tooling changes.
• 11. Assess supply chain resilience, including capacity, lead times, and contingency sourcing.
• 12. Require packaging, handling, and storage standards to prevent damage, corrosion, or contamination.
• 13. Use clear documentation requirements for certificates, test reports, drawings, and compliance records.
• 14. Partner with suppliers that offer engineering support, prototyping, and continuous improvement.
• 15. Measure supplier performance regularly using quality, delivery, responsiveness, and cost metrics.
