 Tooling:
Our 30 years of accomplishments insure consistent results. Costs are very dependent upon cavity configuration.
- The RYNITE, Ryton and ZYTEL are thermoplastics
with faster molding press time
- Farboset and Fiberite are Thermoset materials
- Norcast 3259, 2 part liquid epoxy, is the slowest
of the Encapsulant processes The material requires
vacuum impregnating and oven time
Other Considerations:
- Heat dissipation- Farboset 1115 dissipates heat
approximately 3 times faster than most engineered
thermoplastics plastics
- Coils using magnet wire finer than 38 AWG benefit
from using the gentle pressures used in thermoset
transfer molding
- Special design techniques are required Injection
molding coils with integrated electronics( diodes,
varistors, TVS). These components need to
be protected from high pressure
- Overmolded water resistant coils use design techniques
to minimize weeping at lead/ terminal area
- Explosion proof coils are designed with exacting
verification that all air has been pushed out
- Our thermoset, Farboset 1115, proprietary, will mold thinner wall sections than most thermo plastics
