| Precision | 0.1-5g | $0.50-$3.00 | $0.25-$1.50 |
Note: Prices are estimates and vary by supplier, material, and market conditions. Titanium and refractory metal parts command 2-4x premium over stainless steel.
FAQ
Q: How do I verify a MIM supplier's capabilities?A: Request a supplier questionnaire covering equipment list, material capabilities, quality certifications, and customer references. For critical applications, conduct an on-site audit including facility tour, process documentation review, and quality system assessment.Q: What is the typical MOQ for MIM parts?A: Most MIM suppliers require 5,000-50,000 pieces minimum per part number. Some suppliers offer lower MOQs at higher unit prices. For prototyping, some suppliers provide CNC-machined equivalents before committing to MIM tooling.Q: How long does MIM tooling take?A: Typical MIM mold lead time is 4-8 weeks depending on complexity and supplier workload. Multi-cavity molds for high-volume production may require 6-10 weeks. Plan accordingly for program timelines.
