I have a remote car door control, and a piece of the plastic case has been
snapped off. The piece has one of the key-ring loops at the top. The other
loop is on the undamaged half of the case.
Can find no markings which seem to identify the plastic type. Inside the
case, maybe written by hand in white paint, is 2c, and below that, 23. Any
other markings are FCC and Canadian radio compliance codes, etc. The maker
Markings as on exterior of cover: FCC ID:HYQ1512S, CANADA:1551 102 326,
RSS - 210, DENSO.
The broken piece is large enough to work with, about 1 1/8" long and 3/4"
wide. The break is roughly a straight line, the edges are ragged and don't
fit together tightly. Some unknown person has in the past tried to repair
with what looks like plastic model cement. It hasn't held, and I've peeled
the cement off.
After Googling a lot, I still don't know how to identify the type of
plastic, and how make a solid repair. Using "Ambroid ProWeld Professional
Plastic Welder, For styrene, Butyrate, ABS & Acrylic (Lucite or Plexiglas)"
the parts are together now, but not very securely.
Working from the inside so it looks ok, would hot glue gun material work?
Or use a soldering iron tip to smooth and seal the edges? (I've not had
good results with this in the past)
Help would be welcome.
