Latest Patents

One of Trewiler's latest patents is a "Stamp press process for imprinting decorative textures in thermoplastic." This invention focuses on a method for creating a mold that can transfer three-dimensional relief from a textured substrate to thermoplastic composite material. The process involves preparing a molding core by loading a press with outer layers of textured substrate and an inner layer made of a combination of an epoxy non-woven glass mat and a woven glass cloth prepreg. The press is actuated at low pressure while heat is applied to pregel the epoxy, followed by an increase in pressure to form the molding core. Molds are then prepared using a similar method, and the final product is a thermoplastic composite imprinted with the relief of the molds.

Another notable patent is the "Method of making drill back-up material for small bore drilling." This invention presents an improved back-up sheet designed to support a workpiece during small bore drilling processes. The sheet possesses electrical properties, making it suitable as a laminate in the construction of multi-layer printed wiring boards. The laminate comprises the cured residue of specific materials, enhancing its functionality in various applications.
