A method for manufacturing a housing is disclosed. The method includes: roughening a first surface of the housing; placing the housing into a mold and performing an injection molding to form a plastic layer on the first surface and closely bonded to the housing; and defining a plurality of slots by cutting through the housing by means of milling without milling a part or all of the plastic layer, wherein the plastic layer is configured to keep a connecting portion between adjacent slots defined in the housing undeformed during the milling. A mobile terminal is also disclosed.

A method of automatically advancing a polymer cut-board, such as cellular polyvinyl chloride, through a stationary, non-spinning sealing element having a rounded or cylindrical surface that contacts and compresses a cut edge of the board to provide a sealed skin surface to the cut edge.

The invention provides a method for the production of a 3D printed object (100), wherein the method comprises (i) a 3D printing stage, the 3D printing stage comprising 3D printing a 3D printable material (110) to provide the 3D printed object (100) of printed material (120), wherein the 3D printing stage further comprises forming during 3D printing a channel (200) in the 3D printed object (100) under construction, wherein the method further comprises (ii) a filling stage comprising filling the channel (200) with a curable material (140) and curing the curable material (140) to provide the channel (200) with cured material (150), wherein the cured material (150) has a lower stiffness than the surrounding printed material (120).

A polymer board with a cut edge is automatically advanced through a stationary, non-spinning sealing element that contacts and compresses the cut edge and provides a sealed and smooth surface to the cut edge.

A nozzle for extruding a composite material from an extruder barrel. The nozzle includes a body and a tapered nozzle passage extending through the body. The tapered nozzle passage having a nozzle inlet opening configured to interface with the extruder barrel, and a nozzle outlet opening, where the tapered nozzle passage has a contoured nozzle passage surface extending between the extruder barrel and the nozzle outlet opening with smooth transitions, free of angles, so that each nozzle passage surface portion, having a corresponding contour, transitions smoothly to each other nozzle passage surface portion, having a respective different contour, from the nozzle inlet opening to the nozzle outlet opening, and the nozzle outlet opening is defined by at least a first edge and a second edge that intersect each other at an acute angle.
