The spinneret is a key part of the production of synthetics.
The most important method of synthetics shaping is melt spinning,whose main products are polyester, polyamide, polypropylene and the like.
WuZhong Spinneret produces a variety of high-precision hole type or irregular shape hole type melt spinning spinnerets, and also designs and manufactures spinnerets according to demands of customers.
1 Test pressure of spinneret, see this table.(MPa)
| Spinning fiber | Tile-shaped | Hat-shaped |
| Viscose | 0.8 | 0.8 |
| Vinylon | 1.2 |
| Acrylic | 1.5 |
2 Spinneret finished hardness is more than HV180.
Note: the weight of the test is 0.98N and the holding time is 15s.
3 Surface roughness
a. Spinneret surface roughness Rz ≤ 0.4μmm
b. The rest of the surface roughness Rz ≤ 3.2μmm
4 Naked eye significantly pits, scars, creases and wavy are not allowed in the surface hole area of the spinneret which spinning short filament , non porous area allows a few defects.
The spinneret surface of spinning long filament is not allowed to be defective.
Note:
a. The hole area refers to the inner side of the hole group, and the edge of the outermost hole of the hole group adds a pitch-row to the enclosed area.
b. In addition to the above areas, the rest section is nonporous area.
5 For the hat-shaped spinneret, the flatness tolerance of the spinneret surface and the edge of the hat is shown in following table. (mm)
| Diameter of the hat-shaped spinneret | Spinneret surface | Edge of the hat |
| ≤Φ30 | 0.15 | 0.20 |
| >Φ30~50 | 0.25 |
| >Φ50~65 | 0.45 | 0.30 |
| >Φ65 | 0.60 |
6 The spinneret holes are arranged evenly, and the straightness tolerance of the channel is 0.15mm.
