CHICAGO (July 14, 2 p.m. EDT) — After three years of development, Wilmington Machinery has announced a new rotary blow molding machine.
The machine can produce large bottles up to 4 liters by a single parison, medium-size bottles up to 1.5 liters by dual parisons or small bottles up to 0.75 liters by triple parison, with dual neck-to-neck cavities.
The machine is designed to make single-layer bottles from high density polyethylene, standard polypropylene and clarified PP, according to Wilmington.
Wilmington said the machine is available in 12- 15- and 18-station models and can produce 60-90 large bottles per minute or 360-550 small bottles per minute, running high density polyethylene.
The new rotary machine can run most bottle shapes, including jars, bottles with handles and containers with offset necks. Wilmington offers optional in-mold labeling equipment.
The company continues to offer its line of horizontal rotary blow molders, which are suited for coextrusion. A patented, dual-parison version of the horizontal machine was first shown at NPE 1997.
Wilmington also makes structural foam molding machines.
