Desktop basalt filament winder made in US

US-based startup X-Winder created the world’s first small scale winder for continuous fibers, including basalt fiber. The machine can also process carbon fiber, Kevlar or fiberglass.

Necessary rock studies of the gabbro and andesite basalt groups for the suitability as the raw material base for the production of continuous basalt fiber (CBF). A unique technique including laboratory melting and pilot-industrial melting at the high-tech equipment.

X-Winder allows for making parts up to 7 mm in wall thickness with strength nearly the same as other commercially available products. However, the cost of parts built by X-Winder is 50% to 80% less than the equivalent parts from a commercial vendor. This desktop winder’s power supply accepts 220V input.

X-Winder can be operated on any working space, making the winder suitable even for small workshops. The developers have tried to make their equipment affordable for small workshops, “garage” laboratories and enthusiastic amateurs.

The winder ensures quality with the maximum mandrel diameter of 8” in width. The equipment does not monitor the filament end so the winding process must be under control. X-Winder costs $ 1195 in the maximum configuration.

The project is looking for backers on the Kickstarter crowdfunding platform. By mid-December they raised over $80 000 out of requested $10 000.
