Molds contact

At the gob feeder, the forming operation begias. The gob feeder deUvers a glass gob shaped such that it enters the blank mold without excessive mold contact, distortion, or reshaping of the glass. Shears cut off a gob of glass. The gob is fed to either a blow and blow, press and blow, or press-only forming operation to produce a container.

Direct chill casting is the pouring of molten aluminum into a water-cooled mold. Contact cooling water is sprayed onto the aluminum as it is dropped into the mold, and the aluminum ingot falls into a water bath at the end of the casting process. 

The preparation of molded contact lenses using the polymers of the current invention are described by the author [1] in an earlier investigation.

A knockout system is required to eject the part from the mold (see Chapter 7 Mold Design"). On most machines there is an adjustable stationary ejector plate containing ejector bars which go through the movable platen. As the mold closes, the ejector bars go through the holes in the back platen of the mold, contact, and stop the mold knockout plate. The rest of the mold continues to close to a predetermined distance and stops. A superior method to activate the knockout system is by use of hydraulic cylinders. This permits advancing or retracting the knockout system with any speed or force. This can be particularly useful in cam and insert molding.

It was found that the temperature recorded by the intrusive thermocouple depended heavily on the set barrel temperature and the temperature of the mold contacting the nozzle. Based on theory we would expect to see the melt temperature readings increase with injection velocity due to the increased viscous dissipation. As seen in Figure 1, the flow channel in the nozzle leading up to the...
