1982

Mold Nozzle with interchangeable tips for design and operation flexibility. The evolution of modern runnerless molding begins.

Hydraulic Sequential Controller is introduced. Sequential valve gating is born. Molding dissimilar cavities in the same mold, controlling weld line placement, insert molding, cascade filling of cavities and low pressure molding all started right here.

1983

Developed the first self contained floating hydraulic cylinder to "float" with the manifolds thermal expansion. Dramatically reduced machining and installation time. The pin guide was a further enhancement in valve gating to eliminate gate wear.

1984

Two Stage Filter provides the largest filtering capacity.

The resin is mixed and filtered introducing a more homogeneous melt to the mold.

1985

Multi-Gate Nozzle with individual gate temperature control for processing reinforced engineering grade resins as well as commodity resins.

1987

Mold Nozzle Bodyless Tip style provides the optimum gate cosmetics.

1988

Mold Nozzle Full Body Tip style provides both excellent cosmetics and design flexibility.

1991

SCV Self Contained Valve Gate System.

Osco revolutionized valve gating again by placing our cylinder outside the mold for quick and simple valve pin settings as well as greatly reducing the complexity associated with machining and installation of the hydraulic cylinder.

1992

Adjustable Valve Gate was introduced as a hybrid between the valve gate and Flow Control System. The system provides solutions to molding high cavitation molds with a positive shut off.

Adjustable Flow Control System. This simple yet practical innovation allows the molder to control the resin flow through each nozzle. This manual control is perfect for balancing family molds, controlling knit line placement, as well as balancing clusters of gates in high cavitation molds.

1995

Machine Driven Valve Gate System

1996

DSCV Dual Self Contained Valve System. With the eye on ultra-large part molding and pin gating, this latest system will be the "work horse" nozzle for the next decade.

Pin gating is a two stage process where our valve pin opens and closes the flow of resin as well as coring out a hole in the product.

State of the Art Co–Injection Nozzle allows two different resins to be injected into the mold cavity creating both core material and exterior skin.

2005

External Hydraulic Shut-Off allows for the free flow of plastic without a valve pin. Shut off is accomplished by means of an external hydraulic assembly.
