NN300 vs NN400 Underpinner Comparison
Side-by-side comparison
| Dimension | NN400 | NN300 |
|---|---|---|
| Architecture | Single-corner pneumatic | Quad-angle four-corner cycle |
| Use case | Flexible studio / mid shop | Factory cut-and-join backbone |
| Throughput | Hundreds–thousands/day | ~15 frames/min joining (config-dependent) |
| Automation | Semi-automatic | Fully automatic PLC + auto-feed |
| Profile changes | Frequent — active clamping | Stable SKUs on lines |
| Typical upstream | CT300 / NC500 cutting | NC600 stack cutter |
| Operator model | Hands-on joining | Low-supervision line operator |
| CE certification | Yes | Yes |
Decision tree
Building a linked factory line with NC600?
NN300 is the standard downstream joiner.
Daily volume under 800 frames with mixed profiles?
NN400 retains flexibility and lower capital.
Need four corners without walk-around?
NN300 eliminates repositioning vs NN400 single-corner cycles.
FAQ
Can NN400 sit on the same line as NN300?
Different stations — NN300 serves high-volume lines; NN400 serves flexible cells.
Air requirements for NN300?
Typically 6–8 MPa supply per spec sheet — confirm on quote.
