Claim 18:
19. A method for manufacturing an apparatus for transporting semiconductor elements, comprising:
providing a mold, wherein the mold comprises a cavity contouring a shape of a bottom portion of the apparatus, wherein the bottom portion of the apparatus comprises a front wall, a rear wall, a bottom wall coupled to the front wall and the rear wall, and a pivotal pin structure comprising:
a base support connected to the rear wall and comprising a sidewall; and
a shaft protruding from the base support and comprising first, second, third and fourth side surfaces, wherein:
the first and fourth side surfaces are connected to the sidewall; and
the first and second side surfaces are connected at an angle greater than 90°;

heating the mold to a first temperature;
heating a polycarbonate resin to a second temperature under an environmental temperature between about 22° C. to about 37° C., such that the polycarbonate resin converts from a solid state into a molten state;
heating a barrel of a mold injection apparatus;
flowing the polycarbonate resin through the barrel;
injecting the polycarbonate resin into the mold through a nozzle attached to the barrel to form a solid structure;
cooling the solid structure; and
imprinting at least one identifying code on at least one exterior surface of the solid structure.
