Progressive touts hot sprue bushings
New hot sprue bushings from Progressive Components have a copper core, giving them a very even heat profile and consistent heat transfer, according to the company in Wauconda, Ill.
Progressive said the sprue bushings include a wire channel insert and a recessed connector, eliminating loose and exposed wires.
The company also has developed a standard side-action device for molds, called the 100 Series CamAction.

Immersion Graphics bathes parts in design
Immersion Graphics Corp. of Columbus, Ga., has developed a new way to decorate plastic parts — by dipping them in a design that is floating on a water bath.
Here is how the Final Finish process works: A photo or computer-generated picture of the desired design is electronically transferred to rolls of film.
The film is then floated in an immersion tank and sprayed with a special chemical activator. The film itself dissolves into a ``gelatinous state,'' which floats on top of the water, according to the company.
The operator sprays a base coat onto the part, then dips it into the liquid. The image clings to the part, wrapping itself around all surfaces of the part, even into corners.
The operator dries the part, either in the open air or a special oven.

Pad printing now has 13 base-color inks
Companies that use pad printing machines no longer have to rely on ink designed for the silk screening process which has been slightly modified for printing, thanks to a new ink from Teca-Print USA Corp.
Teca-Print's color ink has a heavier concentration of pure pigments, for a high level of opacity.
The ink also boasts much faster drying and curing cycles. Thirteen monopigmented base colors allow very accurate color matches, according to the company in Billerica, Mass.
