High- and low-pressure RTM metering/mixing equipment and clamps, RIM and large LD-SRIM systems.
High-pressure RTM series has hydraulic cylinders with component metering capacities from 500 to 20,000 cc each, typically paired in a 4:1 or greater size ratio. Process controls for all machine functions, with optional full computer interface and SPC package. High-pressure impingement mixhead has external recirculation. Can be modified for high-temperature applications to 400 F.
Quantum Flow is an entry-level RTM machine with reportedly excellent metering capability, ratio control, and flexibility. Provides continuous material flow with accurate hydraulic metering at ratios from 100:1 to 1:1. Handles most fillers, including chopped fiberglass.
Dura Flow cylinder-type RTM machine processes polyesters, vinyl esters, epoxies, and urethanes. Large-volume resin cylinder is mechanically linked to low-volume catalyst cylinder. Quick-change linkage varies ratio in four discrete increments from 20:1 to 200:1. All-pneumatic operation, material recirculation, special cylinder design with equal flow in both directions, and large free-flow material path.
Tech Flow top-of-the-line RTM machine with PLC or computer controls and complete SPC capability features full closed-loop ratio and output control, temperature control system, injection by constant pressure or flow rate, and Windows-based interface. Customized to meet production or laboratory needs.
Two exhibitors at this month's NPE show in Chicago will be showing new high-pressure RIM systems designed for low throughput and low cost.
Despite the small number of polyurethane and RIM exhibitors, you will find some interesting new materials and equipment technology.One highlight will be a novel aliphatic PUR cast elastomer technology said to enable production of highly transparent parts with unique property profiles.
