Procurement Recommendations

Choosing the Right Supplier

1. Match process to part requirements — if your part requires MIM-level precision with ferrous materials, die casting suppliers cannot meet your needs

2. Verify certifications — automotive requires IATF 16949, medical requires ISO 13485, aerospace requires AS9100

3. Consider total cost — include shipping, duties, and inventory carrying cost, not just per-part price

4. Evaluate engineering support — suppliers with DFM capability can save 15-30% on part cost through design optimization

5. Request samples — always validate quality with prototype parts before committing to production

Negotiation Tips

• Volume commitments — 12-month volume commitments typically yield 10-20% price reduction

• Multi-part programs — bundling multiple parts with one supplier increases leverage

• Tooling amortization — negotiate tooling cost amortization over production volume rather than upfront payment

FAQ

Q: What is the typical MOQ for MIM suppliers?

A: MIM suppliers typically require 1,000-10,000 pieces minimum, depending on part size and complexity. Some suppliers accept lower volumes at a premium.

Q: How do I request a quote from these suppliers?

A: Prepare a 2D drawing with critical dimensions, material specification, annual volume, and quality requirements. Most suppliers respond within 3-5 business days.

Q: Should I choose a single-process or multi-process supplier?

A: Multi-process suppliers offer process optimization (each part uses the best process), supply chain simplification, and single-point accountability. Single-process suppliers may offer deeper process expertise for very specific applications.

Summary

North America offers a robust supplier base for MIM, die casting, and precision casting. The key to successful sourcing is matching your part requirements to the right process and supplier capabilities. For complex assemblies requiring multiple processes, multi-process suppliers like BRM can optimize each component individually while simplifying your supply chain.
