Using the company's patented vacuum molding system, the Vacu-Jet Vacuum Rubber Injection Molding System eliminates or minimizes the entrapment of air or gases that cause defects in molded products. The machines utilize a FIFO (first in-first out) system that allows the first material introduced to be the first material injected. This assures proper residence time for the material and a high level of shot consistency. Vacu-Jet injection molding systems are available in a number of models with injection molding capacities of 500cc to 10,000cc and with clamping forces from 100 to 1,500 tons. Platen sizes range from 16 in. x 16 in. to 44 in. x 44 in.
