components of the X-ray glasses are;



Step 1: Molding

The injection molding is
applied to the raw material plastic for the formation of x-ray glass frames.

The preparation involves
the hollow metal matrix desired shape and size of the frame. The frame unit may
be either single or separated which must be connected. Usually, manufactured as
single unit.

2: Melting

The melting process melts
the plastic polymer pellets by transferring pellets from the holding bin to the
liquefying machine. At extremely high temperature, almost 300°F (149°C), the
plastic pellets have been melted. After the liquefaction of the plastic,
molding takes place again through injection. The melt passed at extremely high
speed and pressure into the mold. The mold is filled by the melt and some more
melt is added to overcome the plastic contraction after solidification and

3: Separation

After the cooling of
plastic polymer, it has been separated from the mold and then passed from the
conveyer belt automatically for further processing.

4. Finishing

Finally, the frames have
been smoothed. The abrasive machine smoothed the frames by removing rough edges
and extra plastic.


Lenses of x-ray glasses
have been made by using cardboard. The grade and thickness of the cardboard
have been depending on the designer’s choice. Before the cutting of the lenses,
the cardboard sheets have been sent to the printing press. The printing press
drawn sheets in the huge rollers machine. The ink from the rollers have been
transferred to the sheets creating black and white spiral outward appearance.

5: Cutting

The blanking machines cut
the lenses from the cardboard sheets, after the settlement of decoration. The
cardboard sheet rolled into stamper machine. The stampers have a series of
metal cookie cutters essentially to cut the sheet in the exact size and shape
of the lens. As the cardboard sheet have been rolled, stampers reached down
towards the cardboard and cut exact shape of the lens.

6: Conditioning

The lens is positioned
perfectly on the front side for the decoration after cutting. The shaped lens folded
over to make a double layered lens.

7: Finishing

using puncturing machine, gaps are stamped into twofold layered focal points.
The cut-outs are put so that a metal bar with the same size as the craved gaps
can punch through the center of each focal point. The focal point is at that
point opened and a plume is stuck over each gap. The focal point is at that
point refolded and stuck together. The focal points are at that point connected
to the plastic outline. A groove on the outline interior each focal point range
permits the cardboard focal points to snap in. The x-ray glasses are at that
point put into a plastic sack bundling and a cardboard card is stapled to the
best to shut the sack. The card is enhanced with outlines to appear how the
glasses are utilized.
