The following is a brief History of how the IMS SPIRAL System developed.

The introduction of electronic process controls back in the early 1980’s was without a doubt a technological breakthrough. For a lot of OTHER industries, this was a huge step forward. For the injection molding industry, however, IMS questioned the logic of trying to computerize a process so full of variables and lacking in standardization.

Prior to process control, IMS had developed numerous individual products aimed specifically at improving part quality. Full Taper Nozzles and Screw Tip BRODY-rings® are just a couple of examples. Each addressed a specific need and they all were and remain solid, successful products. It was the emergence of the process control, however, that really started us thinking about the injection process as a whole (both the machinery and the material) and what could and should be changed in order to mold better parts.

It was already a proven fact that the current, restrictive R-Screw Process was stretching and deforming the molecular bonds of our plastics and seriously affecting finished part strength. We needed to find ways to get the plastic from the hopper to the mold with the least amount of damage possible. We found that this problem could be solved, in large part, by the replacement of all standard, flat internal tapers with smoother, gentler, logarithmic spiral curves.
