A structure forming apparatus includes a rotary body, an irradiation unit, and a holding member. On the rotary body, a mask that is subjected to patterning is capable of being disposed. The irradiation unit is capable of irradiating an area along an axis direction of a rotation of the rotary body with an energy line with the mask intervened therebetween. The holding member is disposed to be opposed to the rotary body so that a holding area that holds a material cured with the energy line is formed.

Thermal extrusion method to fabricate large-dimension superhydrophobic cylinder pillar arrays with droplet pancake bouncing phenomenon

A thermal extrusion method to fabricate large-dimension superhydrophobic cylinder pillar arrays with droplet pancake bouncing phenomenon. Preparing thermal extrusion mold: the through-hole arrays with 0.8˜1.25 mm diameter, 0.25 mm interval space and 0.6˜1.0 mm height are first obtained on metals, and are then polished, rinsed and dried. Thermal extrusion: polymer materials are first thermally extruded on the obtained mold and cooled to room temperature. Demold: excess polymer materials flowing from the through hole are cut off and then the polymer cylinder pillar arrays are lifted off from the mold. Superhydrophobic treatment: the whole polymer sample is treated using mixed liquid spray consisting of titanium oxide nanoparticles dispersed in fluoroalkylsilane ethanol solution, and the superhydrophobic cylinder pillar arrays are obtained. The method is easy to operate, low-cost, recyclable, effective for different polymer materials, and can obtain cylinder pillar arrays with large dimensions, which can realize efficient large-area and industrial fabrication of the droplet pancake bouncing surfaces.

PATTERNED THREE-DIMENSIONALLY MOLDED FOOTWEAR AND METHODS OF MAKING THE SAME

Methods for manufacturing at least a portion of an upper for an article of footwear that include thermo-forming a pattern on the upper. The methods may include disposing a skin for forming an upper over and inflatable bladder and disposing a mold insert between the skin and a surface of a mold cavity. The mold insert may include a mold pattern including surface features formed in the mold insert. The inflatable bladder may be inflated such that the skin is pressed against the mold insert within a heated mold cavity to form a pattern on an exterior surface of the skin and cause the skin to take on the shape of at least a portion of an upper. In some embodiments, the surface features may be disposed in a gradient pattern configured to provide varying degrees of one or more characteristics to different areas of an upper.

A METHOD OF MOLDING A CONTAINER INCORPORATING SURFACE INDICIA AND THE CONTAINER

A method of forming a container (1) and a container (1) formed thereby. A preform (2), having a generally cylindrical body (60, 8) extending between a closed end (12) and an open mouth, is placed within a mold (20, 22) having surfaces corresponding in shape to the desired container (1). An incompressible medium, which is the end product that remains in the molded container (1), is injected under pressure into the preform (2). Under the influence of the incompressible medium, the preform (2) is expanded into contact with the surfaces defining the cavity, simultaneously forming and filling the container (1). During expanding of the preform (2), portions of the plastic material are forced into a series of recesses (72) defined in the cavity surface (82, 85). With the incompressible medium contained therein, the container (1) is removed from the mold (20, 22) and including a series of raised dots corresponding to the series of recesses (72) defined in the cavity surface (82, 85).
