Rotary Mold

Vertical rotary molds also employ multiple molds on a turret but rotate in a vertical plane. As each mold reaches the die exit, it grasps the parison and closes. Because of the vertical spacing between molds, intermittent extmder action is not required. Vertical wheels are used commercially for high volume apphcations.

The selection of optimum conditions for rotary molding requires extensive experimental investigations of the various processing regimes. Recently, another way has been developed, i.e., simulation of the flow of a liquid system polymerized in a rotary (rotating) mold.178...

As expected, the largest portion of the cycle time is the cooling of the blow molded container in the mold cavity. Most machines work with multiple molds in order to increase production. Rotary molds are often used in conjunction with vertical or horizontal rotating tables (Fig. 3.59 [14]).

Rotary molding n. A term sometimes used to denote a type of injection, transfer, compression, or blow molding utilizmg several mold cavities mounted on a rotating table or dial. Not to be confused with rotational molding. 

In this technique, a rotary mold is used and parts are ejected as a continuous chain, which is later broken up or fed to machines for further processing. (See Fig. C.5.) The entire process can be completely automated for small precision parts and, with the use of hot runner molds, is said to result in considerable savings over conventional methods. 

A traditional molded part of that type are the rear lights of a motor vehicle, which are manufactured using horizontally moving rotary molds which have 3 to 4 components (Figure 1.67).
