SHAMOKIN - D/E Associates has been producing products using injection molding and other ordinary machining techniques for decades.

And while it's now moving on to futuristic 3-D glasses, the procedure is little changed.

"The assembly process is pretty basic," said George DeLellis, project manager and secretary-treasurer for D/E. "It's an emerging market (3D glasses), but it's all old production processes."

Here's how the new production will work for 3-D glasses, as demonstrated at right by George DeLellis, project manager:

TOP LEFT: Thousands of pounds of small, black plastic pellets sit in D/E's building waiting for use.

MIDDLE LEFT: The pellets will be dumped through a bin into an injection mold machine, equipment that D/E formerly used to produce international voltage converters and adaptor plugs for overseas travel. The plastic is heated and injected into sunglass-shaped molds, which were made by Boyer Machines, of Northumberland.

BOTTOM LEFT: Complete sets of frames will drop by the thousands out of the injection mold machines. Each frame will come out attached on "runners" not unlike how parts for a model car or airplane are packaged. They are torn loose from the runners and prepared for assembly.

TOP RIGHT: Lenses made from "circular polarized technology" are cut from rolls of film that will be shipped to D/E from a Boston, Mass.-area company. (This sample is scratched; in real production, all handling of lenses will be done with gloved hands.)

MIDDLE RIGHT: An assembly unit, produced by Latovich Machine Shop, Mount Carmel, is used to press the frames and lenses together. Eight assembly stations are ready for use in an established production line. At least two more assembly lines are planned.

BOTTOM RIGHT: A finished pair of 3-D glasses, which will sell in the industry for anywhere from 50 cents to $1 a piece.
