Durable, PTFE coated precise forming mandrels for manufacturing small diameter parts including extruded tubing and formed rubber bladders are available from Applied Plastics Co., Inc. of Norwood, Massachusetts.
APC PTFE Natural™ Fluoropolymer Mandrels feature a uniform, non-flaking PTFE coating on stainless steel or nitinol wire. Providing an anti-stick surface that exhibits a 0.05 coefficient of friction per ASTM-1894, these mandrels withstand 550°F continuous temperatures with excursions up to 700°F.
Unlike conventional green mandrels that typically flake, PTFE Natural™ Fluoropolymer Mandrels are grit-blasted to enhance the bonding surface. Then the PTFE coating is precisely applied from 0.00005” to 0.0008” thick onto wire from 0.005” to 0.070” dia. with a ±0.0001” final dia. tolerance.
APC PTFE Natural™ Fluoropolymer Mandrels are priced from $1.19 per foot; with delivery from stock. Free samples and literature are available.
