The challenge

The outcome

Requirements

• - Define part requirements: material, density, tolerances, mechanical/chemical properties, finish, volume, lifecycle
• - Classify sourcing risk: criticality, dual-source need, supply disruption impact, region/logistics exposure
• - Build supplier shortlist: relevant sintered process capability, part size/complexity fit, industry experience
• - Verify technical capability: metallurgy, press/sinter, MIM/PM expertise, tooling design, secondary ops, heat treat, machining
• - Check quality systems: ISO/IATF/AS, SPC, PPAP/APQP, traceability, inspection equipment, calibration
• - Review capacity and scalability: current load, lead times, peak capacity, expansion plans
• - Assess tooling ownership and support: tool design, maintenance, replacement policy, sampling process
• - Evaluate cost structure: piece price, tooling, scrap, logistics, duties, inventory, changeover, hidden costs
• - Confirm commercial terms: MOQ, payment terms, warranty, liability, Incoterms, price adjustment rules
• - Validate supply chain resilience: raw material sources, sub-suppliers, backup plans, business continuity
• - Perform sample/FAI qualification: dimensional, metallurgical, performance, fit/function testing
• - Run pilot and approve PPAP/FAI: establish acceptance criteria, documentation, deviation control
• - Audit operations: process controls, housekeeping, preventive maintenance, worker skills, EHS compliance
• - Establish governance: KPI dashboard, escalation path, review cadence, corrective action process
• - Define onboarding plan: contract, specs, drawings, packaging, labeling, EDI/order flow, forecast process
• - Set performance targets: OTIF, PPM/defects, lead time, responsiveness, cost, innovation
• - Lock change control: no material/process/tooling changes without approval and validation
• - Implement continuous improvement: cost-down, yield improvement, risk reduction, design-for-manufacture reviews

Best practices

• 1. Define the application requirements clearly, including load, wear, temperature, corrosion, and dimensional tolerances.
• 2. Match the sintered material grade to the performance needs, not just the lowest unit cost.
• 3. Request full material and process specifications from suppliers before qualification.
• 4. Verify supplier experience in your industry and with similar part complexity.
• 5. Evaluate dimensional capability, repeatability, and secondary operation requirements early.
• 6. Confirm porosity, density, and mechanical property targets for the intended use.
• 7. Review tooling ownership, tooling life, and tooling maintenance responsibilities upfront.
• 8. Require sample parts and production-quality prototypes before committing to volume orders.
• 9. Assess the supplier’s quality system, inspection methods, and traceability controls.
• 10. Validate lead times, production capacity, and supply continuity for long-term demand.
• 11. Compare total cost of ownership, including tooling, machining, finishing, logistics, and scrap risk.
• 12. Clarify packaging, handling, and storage requirements to prevent damage or contamination.
• 13. Ensure regulatory and compliance needs are covered, such as RoHS, REACH, or industry-specific standards.
• 14. Build in change-control procedures for material, process, or design modifications.
• 15. Establish a collaborative relationship with the supplier for design optimization, cost reduction, and ongoing process improvement.
