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.
