Multi-needle electrospinning for production

Multi-needle electrospinning is widely used to scale nanofiber production. TONGLI offers different needle counts and arrangements, combined with controlled motion to produce uniform membranes from laboratory trials through pilot-scale work to production.

Compared with needleless electrospinning, the listed advantages are:

1. Flexible needle combinations and arrangements.

2. Close control of spinning process parameters.

3. Stable solution viscosity and concentration.

4. Compatible with TONGLI’s automatic needle-cleaning device.

5. Straightforward temperature and humidity control for production systems.

6. The original product description states that multi-needle electrospinning technology is not subject to patent restrictions.

7. Numerous established applications are available as references.
