How long can you complete production of 5 sets of Plastic Panel extruder twin screw barrel, I really need them fast?

Usually 35 days are needed for production after drawing confirmation. If your size is standard, such as 55/110, 65/132, 80/156 twin conical screw barrel, we’re capable to shorten to 20 days when the time fits perfectly.

Haste makes waste, it’s better to leave more time to production people, because quality is the key. We will help you to save time on other areas, such as drawing preparation, logistics---each day counts!
