1. Introduction
The RTM Megaject Pro, has been designed for injecting polyester, vinylester and
methacrylate resin systems under automatic control. The unit uses the proven
Megaject pumping system, which mixes resin and catalyst on demand at the injection
head, with the catalyst ratio adjustable from 0.5% to 4.5%.
The machine incorporates the programmable progressive catalyst ratio (PCR) facility,
which is motor driven and provides automatic catalyst ratio adjustment between 200:1
and 22:1. Interfaced with the machine’s control system, it responds to individual
mould programs and adjusts the percentage of catalyst based upon the settings in the
selected program.
