PROBLEM TO BE SOLVED: To facilitate the wiring of a plurality of cables by only one person. ;SOLUTION: This molding for wiring is a base member 1 for molding used for wiring a communication cable on a wall surface, and is formed by applying an adhesive 4 on the bottom surface 3 of a...
Using the 3D nanomolding process, continuous microscale ratchet gratings were patterned on the sidewalls and bottom of the microchannel to realize 3D T-micromixer structures. By using a solvent-assisted bonding technique with a plain or micropatterned cover plate, enclosed T-micromixers with no side...
The baseline used in the calculation was the center line of the arithmetic average, i.e., the line when the top and bottom areas of the contour were equal. It should be noted that the surface roughness of the molded PEEK samples was greater than the surface roughness of the mold (Ra≈...
Third, fiber–wall interactions happen at contact locations to machine parts. This is visible by the abrasive wear that can be found on the screw, the barrel, and other machine parts. Agglomerations and fiber bundles reduce the overall extent of the fiber shortening, resulting in a higher ...
After employing DOE and ANOVA, the results demonstrated that flow progression and hesitation are dependent on wall thickness, injection velocity, and material type. Loaldi et al. [33], using the same techniques (DOE and FEA) focused on the experimental validation of the injection molding ...
Side-action cores are moving elements that enter the mold from the top or the bottom and are used to manufacture parts with overhangs (for example, a cavity or a hole). Side-actions should be used sparingly though, as the cost increases rapidly. Interesting fact: About 50% of the typical...
Molding method of blow-molded container The present invention provides a blow molded container and molding method. In the synthetic resin bottle-shaped direct blow molded article, three or more slits so that the bottom surface of a ridge line formed at the bottom of the remain... 黑泽孝雄 ...
A method of forming a cosmetic product by back injection molding is disclosed. The method includes providing a pan having at least one removable wall therein. Each removable wall forms at least two compartments in the pan, with each compartment having apertures therein. The method also includes ...
