Provided is a method of polymer molding of cables and connections, such as undersea cables and connections using additive manufacturing. Design requirements for cables/connections, including form, fit, and function data is provided. The requirements are used to produce a three-dimensional model of a mold, which is converted into a file format that allows for three-dimensional printing and computer-aided manufacturing. A mold is printed utilizing a UV cured resin on a high resolution three-dimensional printer. The mold is then checked to ensure it meets form, fit, and function data. Finally, an cable/connection is molded by mixing polyurethane, injecting it into the mold, and baking. The disclosed method provides significant time and cost savings when compared to prior art steel and aluminum mold manufacturing.

A method for making a composite piece comprised of a metal part and a glass-fiber-reinforced plastic part, comprising: providing a metal part with a receiving cavity and a flow guiding channel, the flow guiding channel having an inlet communicating with the receiving cavity and an outlet; introducing molten plastic reinforced with glass fibers into the receiving cavity to fill the receiving cavity and the flow guiding channel and overflows from the outlet to form a flash section; curing the molten plastic to obtain a plastic part; removing unwanted portion of the metal part together with a portion of the plastic part to obtain the composite piece, wherein the glass-fiber-reinforced plastic part includes an exposed surface and glass fibers exposed at the exposed surface are substantially parallel to each other. A metal-plastic composite part prepared by the method and an electronic device housing are also disclosed.

The invention belongs to the technical field of integrated machining of lenses and provides an integrated injection-molding method for a lens and a lens formed by the integrated injection-molding method to overcome the defect of poor sealing performance of lenses in the prior art caused by separate assembly of the lenses during production. In the invention, a high-transparency polycarbonate material is purified to remove impurities and moisture; then, an integrated mold is debugged; a material plasticization and filling process, a temperature holding process and a cooling process are accurately controlled by means of an injection molding machine to realize integrated formation of a lens and a product body; and after being formed, the product body is processed, and performance is detected. In this way, the sealing performance of the lens is improved.
