Epoxies form strong bonds that can take thousands of newtons to break apart. However, the strength of the epoxy is directly related to the surface area and cleanliness of the substrates.
The impact of COVID-19 on this country didn’t need to be this bad. It shouldn’t have been this bad. But this is what happens when a country turns its back on manufacturing. America traded its independence for short-term corporate profits, and recovery is going to take much more than a few trillion dollars in federal emergency loans. A euthanized industrial base can’t magically be brought back to life.
DETROIT—With ventilators and face masks now in production, GM is expanding its manufacturing of personal protective equipment, including latex-free face shields, protective gowns and aerosol boxes. All of these supplies are being donated.
Stripping coaxial cables places high demands on processing equipment. Several thin, concentric layers must be carefully removed within a single cycle: insulation, metal braiding, foil and dielectric. The strip length must be exceptionally accurate, since the tolerance ranges of coaxial connectors are narrow.
Like any assembly skill, manual soldering of wire can be learned through proper training. This training begins by teaching the person how to cleanly strip, tin and solder the wire to a connector, PCB or terminal.
Of the many steps in the process of assembling a wire harness, testing the crimped terminal is a crucial one. If the terminal hasn't been properly attached to the end of the wire, it can cause the wire and eventually the entire wire harness to fail. Most manufacturers use pull testing to assess crimped connections and ensure that terminals are properly attached.
With so many ways to formulate plastic to get just the right combination of color, texture, strength and durability, it’s easy to forget how the parts will be assembled. However, if the parts will be assembled with screws, overlooking such parameters as thread style, driver speed and boss design could spell disaster on the assembly line.
