Cycle Time Reduction by 30% in Injection Molding; Liquid CO2 Spot Cooling

Introduction
In custom injection molding, time plays a key role to how much each part is worth; where conventional water cooling methods may take up to 40-60% of the overall cycle time. Vision Plastics sees this is as an opportunity to embrace a more efficient method of managing cycle time called CO2 Spot Mold Cooling (SMC) technology. This injects liquid carbon dioxide (LCO2) in controlled pulses through tiny capillary tubes into strategic areas of the mold. By supplementing existing water lines with this method of cooling, we can potentially decrease the cooling time by up to 50% and the overall cycle time by 30% in some cases.
