1. A method for forming an apparatus for transporting semiconductor elements, comprising:
providing a mold, wherein the mold comprises a cavity contouring a shape of a top portion or a bottom portion of the apparatus, wherein the bottom portion comprises a front wall, a rear wall, a bottom wall coupled to the front wall and the rear wall, and a pivotal pin structure extending from the rear wall and 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 second side surface is connected to the first side surface;

heating the mold to a first temperature;
providing a polycarbonate resin in a solid state;
heating the polycarbonate resin to a second temperature under a humidity level from about 30% relative humidity to about 85% relative humidity, such that the polycarbonate resin converts from the solid state into a molten state;
heating a barrel of a mold injection apparatus to a third temperature greater than the second temperature;
flowing the polycarbonate resin through the barrel;
heating a nozzle of the mold injection apparatus to a fourth temperature;
injecting the polycarbonate resin into the mold through the nozzle to form a solid structure; and
cooling the solid structure to form the top or bottom portions of the apparatus.
