Spherical carbide makes thicker, tougher cladding.Thicker carbide cladding The plastic or glass sheath that is fused to and surrounds the core of an optical fiber. The cladding's mirror-like coating keeps the light waves reflected inside the core. The cladding is covered with a protective outer jacket.

Entek also developed a proprietary process that reduces the lead time for making a carbide-lined barrel. Its mechanical bonding method boasts greater strength in the apex region between the bores, compared with standard brazing brazing, method of joining metal parts using nonferrous filler metals with high melting points such as copper, silver, and aluminum alloys. Brazing differs from soldering (see solder) by using a higher temperature; and unlike welding, the parts are not melted. . The new cladding is also thicker--.150 in. vs. 0.01 to 0.065 in. for typical brazed carbide cladding. The new cladding is offered for Entek's E-Max twin-screw extruders and replacement barrels for other brands. Tel. (541) 259-1068 * PTDirect: 151VT [ILLUSTRATION OMITTED] |
