Types of metal component parts including a casing, a bezel, a buckle, parts for a watch band, etc. are made with the Metal Injection Molding (MIM) process. Each type of metal component part can be derived from an instance of a MIM blank corresponding to that particular type of metal component part formed from its corresponding injection molding tool. The MIM blank formed for the metal component part from the injection molding tool then has a portion of the MIM blank subtracted through a laser subtraction process to form an interim shape and geometry of the instance of the metal component part. The laser subtraction process is applied to the instance of the MIM blank for the metal component part when the instance of the MIM blank has not yet been sintered and hardened to a finished shape and geometry for that metal component part for the watch design.

The present disclosure provides methods and systems for composite-to-metal hybrid bonded structures compromising the laser surface treatment on titanium alloys to promote adhesive bond performance. For example, a computer may be programmed to set a laser path corresponding to a predetermined geometric pattern. A laser may be coupled to the computer and apply a pulsed laser beam to a contact surface of the titanium alloy along the predefined geometric pattern. The laser may generate an open pore oxide layer on the contact surface of the substrate with a thickness of 100 and 500 nm. The open pore oxide layer may have a topography corresponding to the predefined geometric pattern. The topography may contain high degree of open pore structure and promote adhesive bond performance. Adhesive, primer or composite resin matrix may fully infiltrate into the open pore structures. Adhesive and composite laminate may co-cure to form composite-to-titanium hybrid bonded structures.
