MCP and Vantico Introduce Nylon Part Casting Process and New Prototyping Materials

EAST LANSING, Mich., May 13, 2003 - A new method for rapid manufacturing of nylon prototypes and parts along with a new RTV silicone rubber for molds and two new PA-6-type nylons were introduced today by MCP Systems and its North American distributor, the RenShape® Solutions Tooling Group of Vantico A&T US Inc., at Rapid Prototyping & Manufacturing 2003 in Chicago. Also announced was a new polyurethane for vacuum casting.

The new process utilizes a specially designed MCP/04 vacuum casting machine that is now available in the U.S. from Vantico. The equipment, fitted with a unique nylon program module, yields economical, production-quality nylon parts in just six minutes. The process is especially well suited for producing complex, thin-walled (0.02-inch/0.5-mm thick) prototypes that are both durable and able to withstand exposure to heat, chemicals and abrasion. The nylon castings are also air- and water-tight, making them ideal for functional testing of automotive inlet manifolds as well as parts used in electrical, medical and recreational equipment.

Also introduced for nylon casting were an easy-to-handle MCP silicone rubber for fast production of durable (20+ parts) molds and two nylon formulations. MCP's PA 700 and PA 1000 nylons are PA-6-grade plastics that exhibit performance characteristics including: flexural moduli of 108,750 psi to 137,750 psi, tensile strengths of 4,640 to 6,090 psi, and heat deflection temperatures of 169°F to 269°F (76°C to 132°C) @ 66 psi.

A new vacuum casting polyurethane, designated RenPIM-VG SG 220, was unveiled at RP&M as well. The product is transparent white for easy pigmenting and features a low, easy-to-handle viscosity. It produces durable parts with a flexural modulus of 285,000 psi, tensile strength of 8,100 psi, elongation of 8% and heat deflection temperature of 198°F (92°C).
