Latest Patents

Highum's latest patents include a groundbreaking method for manufacturing an electro-magnetic shield. His design features an enclosure that serves as a barrier to electro-magnetic radiation. The typical cross-section of this enclosure consists of three parallel layers. The outer and inner surface layers are composed of a polymeric base material in which suspended electrically conductive fill material is integrated, resulting in relatively high electrical conductivity. The middle layer is crafted from a polymeric base material that contains fill material with high magnetic permeability, providing the middle layer with enhanced magnetic properties.

The preferred embodiment of this enclosure is produced using a co-injection molding process. Nickel-coated graphite, known for its high conductivity, is injected into the mold from the outer co-injection nozzle, while carbonyl iron powder, which has high permeability, is injected from the inner nozzle. This innovative approach allows for the creation of an integrated structure containing the three layers in a cost-effective manner, all in a single co-injection molding operation. Moreover, the enclosure may encompass multiple co-injection molded pieces, which can be assembled using various conventional techniques.
