We use industrial-grade extruders which melt and mix our resins with colorant, which is precisely fed at a consistent rate, via gravimetric color feeders.
Once melted and uniformly mixed, the resin is pushed through a heated die and fed into a warm water bath, which quickly cools the filament.
An industrial filament puller maintains the filament diameter, by speeding up or slowing down, based on readings it receives from the laser measuring head. The laser measuring head not only measures the diameter, but also the ovality, or in our case, lack thereof.
Our winding machines then spool up the filament with a traverse feeder, which ensures an even flat winding. This also ensures that it cannot overlap filament and cause a tangle.
Our finished spools are post-dried in our walk-in oven and then immediately vacuums sealed with a desiccant pack to ensure you receive dry filament.
