METHOD OF MANUFACTURING A PIECE COMPRISING SEVERAL PARTS CONNECTED TOGETHER
Disclosed is a method of manufacturing a final piece including several materials, the final piece being produced at least according to the steps of: inserting an elastomer (5) in at least one insertion cavity (6) of an initial piece (2) so that the elastomer (5) is in contact and fixed with the initial piece (2); then cutting the initial piece (2) in at least two distinct parts (3, 4), so that the at least two distinct parts (3, 4) are fixed together but not in contact with each other, the at least two distinct parts (3, 4) being connected together by the elastomer (5). This may be applied to manufacturing a final piece including several parts, of various natures, connected together.
Methods and apparatuses for casting polymer products
In an example method of forming a waveguide part having a predetermined shape, a photocurable material is dispensed into a space between a first mold portion and a second mold portion opposite the first mold portion. A relative separation between a surface of the first mold portion with respect to a surface of the second mold portion opposing the surface of the first mold portion is adjusted to fill the space between the first and second mold portions. The photocurable material in the space is irradiated with radiation suitable for photocuring the photocurable material to form a cured waveguide film so that different portions of the cured waveguide film have different rigidity. The cured waveguide film is separated from the first and second mold portions. The waveguide part is singulated from the cured waveguide film. The waveguide part corresponds to portions of the cured waveguide film having a higher rigidity than other portions of the cured waveguide film.
COMPOSITE PANEL HAVING PERFORATED FOAM CORE AND METHOD OF MAKING THE SAME
A panel for a trailer and a method of making the same is provided. The trailer includes a front wall, a rear wall opposite the front wall, a first sidewall, and a second sidewall. The first sidewall is formed by a first continuous laminate panel that extends an entire length of the first sidewall, and the second sidewall is formed by a second continuous laminate panel that extends an entire length of the second sidewall. The first continuous laminate panel and the second continuous laminate panel each comprise a first skin, a second skin opposite the first skin, and a perforated core between the first skin and the second skin.
