MIM Copper Heat Sinks: Driving Thermal Innovation in 2026

The Heat Is On: Why Thermal Management Matters

The global MIM parts market reached $4.6 billion in 2025 and is projected to grow to $12.2 billion by 2035 at a 9.9% CAGR. Copper-based MIM components now account for ~11% of the market, driven by thermal management demands across AI data centers, 5G, and EV sectors.

Why MIM for Copper Heat Sinks?

• Complex geometries at scale: MIM produces intricate fin structures and micro-channels impossible to machine
• Near-net shape: Minimal waste — critical with copper prices up 30% in two years
• High density (≥96%): Thermal conductivity within 5-8% of wrought copper
• Mass production economics: Per-part costs drop above 50,000 units/year

Key Applications

AI Data Center Cooling:

MIM copper cold plates deliver thermal performance for direct-to-chip liquid cooling — a single AI rack needs 50-200 specialized heat sinks.

5G Base Stations:

MIM copper heat spreaders with vapor chamber designs for next-gen base stations.

EV Power Electronics:

MIM copper baseplates and pin-fin heat sinks for SiC/GaN power modules.
