Need nylon parts fast? Try vacuum casting them using a new rapid prototyping process developed by MCP Systems and offered in North America by Vantico A&T US Inc. (www.vantico.com). Thanks to a new nylon program module, MCP's vacuum casting machines can produce complex nylon parts with walls as thin 0.02 inch—and do so in as little as six minutes. MCP also introduced new nylon 6 formulations for the new process. Properties include flexural modulii from 108,750 to 137,750 psi, tensile strengths from 4,640 to 6,090 psi, and heat deflection temperatures from 169 to 269F (at 66 psi).
The amount of plastic clogging the ocean continues to grow. Some startling, not-so-good news has come out recently about the roles plastic is playing in the ocean, as well as more heartening news about efforts to collect and reuse it.
