The lower section of the mold runs on the machine base and the lower machine tie bars. The top section of the part runs on the upper machine tie bars. In this technology, components are molded within the rotating system at different steps. Below are the different steps-[4] The initial moldings are performed in a cavity of the first parting line.
For instance, a 6-inch-diameter (150 mm) screw at 24:1 will be 144 inches (12 ft) long, and at 32:1 it is 192 inches (16 ft) long. An L:D ratio of 25:1 is common, but some machines go up to 40:1 for more mixing and more output at the same screw diameter. Two-stage (vented) screws are typically 36:1 to account for the two extra zones.
