For more information about Faroex’s new low-cost DCPD molding technology.
Process: A family of lightly cross-linked, olefinic thermoset polymers based on poly-dicyclopentadiene (P-DCPD) with mechanical properties similar to engineering thermoplastics. Faroex molds Telene™ polymer in which two, low - viscosity P-DCPD liquid streams - one containing an activator (A) and the other a catalyst (B) - are impingement mixed at a 1:1 ratio and injected at near room temperature into a closed mold mounted in a “presentation” press. The resulting exothermic reaction creates a fully polymerized part in less than 60 seconds. Button to button cycle times are generally 4 to 6 minutes depending upon size and geometry.
The low viscosity of the liquid components allows the molding of very large parts with surface areas up to 13 m² (120 ft²) or several hundred kilograms (pounds).
Tooling: Production molds are typically CNC-machined aluminum with heating and cooling lines. Ideal volume ranges from 1,500 – 10,000 parts per annum.
Prototyping: Faroex now offers a proprietary process for molding up to 10 prototype parts in DCPD. A new, low-volume DCPD molding technology has also been developed that is capable of forming up to 1000 production-quality parts with a Class “A” finish.
