    Abstract: A composite safety toothbrush is disclosed, and in particular, methods for making and forming the composite. The toothbrush apparatus detailed herein employs a composite head made from a rigid inner polymer material and a softer thermoplastic material surrounding the inner material. The softer material provides safety for prison toothbrush applications as well as elderly and patient care where care givers may brush the teeth of a patient. Innovative pin connectors in the inner toothbrush head assist in the composite formation. The toothbrush solution herein further importantly provides for a toothbrush having a flexible handle, also providing safety in a prison environment.

    Abstract: The present invention discloses a method of manufacturing a housing and an electronic device. The method comprises the following steps: preparing a mold according to a predetermined shape of the housing, wherein the mold comprises at least one moving die and at least one fixed die, a first texture structure is formed on the inner surface of the mold, and the first texture structure comprises a plurality of projections arranged in a first arrangement, and a groove recesses inwardly is formed between any two adjacent projections, and the groove is formed by etching and removing a part of the moving die and/or the fixed die by the laser engraving method; closing the moving die and the fixed die, and heating the mold to a predetermined mold temperature; and injecting a raw material in a melting state into the mold cavity of the mold; retaining a pressure of the raw material in the mold cavity of the mold; cooling the mold; opening the mold to complete the housing. The housing made of the first material exhibits a second material effect in visual and/or tactile senses.
