Moderate	10-50g	$0.50-$2.00	$0.25-$1.00
Complex	10-50g	$1.00-$5.00	$0.50-$2.50
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.
