Various systems and methods for forming a polymer part with utilizing heating fluid are provided. In one embodiment of the present invention a method for forming polymer includes heating the mold apparatus with a first heat energy source comprising heating fluid to a first mold temperature, and then heating the mold apparatus with a second energy source which is different than the first energy source. The second energy source heats the mold surface to a second mold temperature greater than the first mold temperature to form the part to achieve a desired surface finish of the polymer part.

Method for forming a polymer part

Various mold apparatuses and methods for forming a polymer with induction heat energy are provided. In one embodiment of the present invention, a mold apparatus for forming polymer includes a mold having a top mold portion and a top mold surface that is magnetic. The bottom mold portion of the mold includes an induction heating unit that is at least partially embedded in the bottom mold portion that provides induction heat energy to the mold. The mold apparatus is constructed and arranged to dissipate greater than about 50% of the induction heat energy in the top mold portion. The induction heating unit of the bottom portion of the mold provides rapid heating to the top mold surface to provide high surface quality polymer parts and a shorter molding cycle time while utilizing less energy.

Mold apparatus for forming polymer and method

A light collimating and diffusing film and a method for making the film are provided. The film includes a plastic layer having a first side and a second side opposite the first side and at least a first peripheral edge. The first side has a first textured surface, wherein between 7 to 20 percent of slope angles on the first textured surface proximate a first axis has a value between zero and five degrees. The first axis is substantially parallel to the first peripheral edge. The plastic layer collimates light propagating therethrough.
