I remember as a little girl
how my father would use different equipment, soldering irons and welding tools
to fix a broken item, from a digital board of a computer, to the back of the
old RCA tube televisions and other items. On Saturdays as a treat he would take
us to visit his friend's garage. Most girls did not like the smell and
environment of a mechanic's and body shop, I did not either, but it was the
quality time as a female I would have to enjoy with my father and
brothers. I learn a lot about cars and
fell in love with the older models of cars, like Chevy and Ford, which were
easily to repair with the right tools and expertise.
So after I finished
cleaning the shed, I went on the Internet and wonder where people could
purchase items such as welding equipment and other supplies. Surfing around the
sites I learn about the process of welding plastic work pieces together. It is
a very common process for joining plastics. One company that interested me was http://www.heatstaking.com.
They seem to be updated and carried the latest inventory. I check out their
events page and thought my father would be in his glory attending the show and
learning about the different machines that the experts are using now to build
everything that uses plastic and other materials. Also I ponder about the
education required for this specialized skill and which is the future and
global requirement for this generation and next will be.
They would have to learn about small to large
creation from toys to harbor freight and in-between.
I look around more and came
across the Wikipedia page, http://en.wikipedia.org/wiki/Plastic_welding,
If I was younger and decided
to go back to trade school I would study the knowledge of how to do ultrasonic
welding, where a press is used to put the two parts to be assembled under
pressure.
Placed in a nest or anvil
where the parts are placed and allowing the high frequency vibration to be
directed to the interfaces and mould together with clean lines.
An ultrasonic stack composed
of a converter or piezoelectric transducer, an optional booster and a sonotrode
(US: Horn). All three elements of the stack are specifically tuned to resonate
at the same exact ultrasonic frequency (Typically 20, 30, 35 or 40 kHz). I like
holding an item in my hands, and look at the smooth lines that flow throughout
the item. All done by specialized machines with complex parts and produce an
excellent usable product. It is funny
how cleaning out a shed brings about knowledge and I found a site I can
recommend to my dad’s friend’s son, my brother-in-law to investigated as he is
in need of replacing his welding equipment to meet state requirements.
