Abstract: A housing structure includes a substrate, a first adhesive layer, and a silica gel layer. The substrate includes a first portion, and the first portion includes polybutylene terephthalate and glass fibers, the glass fibers and the polybutylene terephthalate are in a ratio between 40% and 50% by weight. The first adhesive layer is formed on the first portion. The first adhesive layer includes polysiloxane in a range of 2% to 5% by weight, acrylic resin in a range of 3% to 5% by weight, isopropanol in a range of 20% to 30% by weight, cyclohexane in a range of 20% to 30% by weight, and toluene in a range of 20% to 30% by weight. The silica gel layer is formed on the first adhesive layer, and the first adhesive layer bonds the silica gel layer to the first portion.

Abstract: An apparatus for inkjet printing and curing process for performing on more than one side of a workpiece in one continuous sequential process, the workpiece is shaped as a cube configured with a first surface, a second surface opposite to the first surface, and side surfaces connected between the first surface and the second surface. The apparatus for inkjet printing and curing integration process comprises a base, a supporting module, a printing module, a rotary module, and a transporting module, wherein the transporting module moves the workpiece under the printing module for being printed and cured on one side, then the rotary module rotates the workpiece such that a different side is presented for inkjet printing and curing. The printing module thus performs a continuous inkjet printing and curing process on more than one side of a workpiece, and the working efficiency is improved.

Abstract: An injection molding process method of a plastic part on a metal shell to form a high-strength combination comprises: forming a molding cavity which is inwardly concave from the outer surface and extending through flanges at periphery of the metal shell to area beneath bridges protruding from flanges, the bridges being removed after the injection molding. A plastic part with slight deformation is in the molding cavity and is tightly combined with the metal shell due to the bridges. The protruding bridges can be removed from the flanges by milling or cutting without damaging the plastic part, thus the plastic part does not require to be remachined, and the appearance of the metal shell is not affected.

Abstract: A method for manufacturing a metal shell for casing of electronic product comprises stamping, squeezing and milling a sheet metal at a first area and a second area to form hinge side walls. The sheet metal on the periphery is stamped, squeezed, and milled to form side walls. Insert molding is performed at inner surface of the sheet metal to form an internal molded plastic part and a fine machining of the sheet metal is carried out. The metal shell is integrally formed from a single solid sheet, the manufacturing process is simple and economical as CNC processes are reduced.
