CFC Threads, Bolts and Rods

Neftec offers class leading CFC Threads, studs, nuts, bolts and CFC Rods for heat-treatment and Vacuum furnace market. CFC Threads are extensively used throughout the construction of; vacuum furnaces, Solar Cell manufacturing, silicon ingot growing, fixtures and fittings.

High performing CFC Threads and other CFC threaded/Non-threaded components are a key Heat-treatment industry, but often overlooked. The correct CFC Thread is vital for many heat-treatment structures and it’s important choose the correct CFC Thread to minimise failure and production downtime. For this reason, Neftec CFC threads are favoured by many leading furnace manufacturers and resellers.

Short-fibre carbon composite CFC threaded bars, bolts, nuts and plain rods offer a lot of advantages over traditional long-fibre composites and high-temperature alloys. The high density and very high inter-laminar strength allows for far greater accuracy and tolerances when machining. This gives a cleaner thread but it also regains it’s high-strength due to the low risk of de-lamination.

Neftec’s CFC threads offer peace of mind to our customers, they know our products offer exceptional reliability, quality and long-life.
