Stringent controls, in place during the casting process, are
extremely critical to ensuring uniformity and integrity in the final
cast coil structure. JST uses the most modern equipment available to
achieve a perfect casting.
We use Hubbers casting chambers, regarded as the best in the
industry. Each winding is fitted to a mold which is then loaded into
the casting chamber. Oil diffusion pumps create the necessary vacuum
inside the casting chamber, to rid the casting of any trapped gases
as the molds are filled with the epoxy resin mixture.
The entire casting process is computer-controlled and
incorporates our unique static mixing process. Using this process,
epoxy resin and hardener are mixed while being fed to the mold.
Static mixing allows better control over viscosity during casting
and better uniformity when curing, resulting in castings that are
void-free with greater structural integrity.
Finished castings are staged to be loaded on the cores in the
final assembly area.
