Comparison of MIM and Extrusion + NC Solutions

MIM pure copper vs. Copper extrusion + CNC machining

Scheme typeMIM pure copperCopper extrusion + CNC
forming logicMold forming complex structure at one timeCNC secondary machining after extrusion molding
Design freedomExtremely high, supports special-shaped, porous and other structuresExtremely high, supports special-shaped, porous and other structures
Production efficiencyThe monthly production capacity is one million, and the delivery cycle is shortened by 40% +The daily production capacity of a single machine is only a few hundred pieces, and the overall efficiency is low
Material utilization rate> 95%, almost no waste is generated< 60%, resulting in a large amount of copper chip loss
Mass production cost30% -50% lower, the larger the order, the more significant the cost advantageThe cost is high, and the room for cost reduction is extremely limited
yield performance> 98%, no cumulative error in one-time molding of the moldAbout 90% -93%, multiple clamping is prone to deviation

Traditional CNC precision machining

The structure is relatively simple and requires extensive cutting
