Traditional potting compounds and secondary silicone seals crack under continuous mechanical vibration, permitting electrolyte fluids to short-circuit internal connections. Encapsulating metal contacts and printed circuit boards directly within engineering thermoplastics creates a monolithic barrier that halts environmental ingress. Achieving a robust bond across heterogeneous materials requires balancing metal surface energies with polymer melt temperatures. This technical engineering guide explores labyrinth shut-off design, differential thermal expansion compensation, and high-voltage insulation standards. Table of Contents 1.
