| Scheme type | MIM pure copper | Copper extrusion + CNC |
| forming logic | Mold forming complex structure at one time | CNC secondary machining after extrusion molding |
| Design freedom | Extremely high, supports special-shaped, porous and other structures | Extremely high, supports special-shaped, porous and other structures |
| Production efficiency | The 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 cost | 30% -50% lower, the larger the order, the more significant the cost advantage | The cost is high, and the room for cost reduction is extremely limited |
| yield performance | > 98%, no cumulative error in one-time molding of the mold | About 90% -93%, multiple clamping is prone to deviation |
Traditional CNC precision machining
The structure is relatively simple and requires extensive cutting
