The mold generally includes two parts, a movable mold and a fixed mold (or a punch and a concave mold), which can be divided and closed. The mold is a precision mold with complex shape, which bears the expansion force of the blank, and has high requirements on structural strength, rigidity, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important signs of the level of machinery manufacturing. http://www.chinainjectionmould.com/plastic-mould/precision-mold/

Cast Film. Cast film is created by feeding a sheet of heated resin through a flat die. The molten material emerges from the die and out onto larger chilling rollers which cool and solidify the material. It is then ready for trimming and rolling. Cast film is minimally pre-stretched compared with blown film giving it improved depth of drawing for thermoforming operations. The cooling process can be used to produce different characteristics in the final product. Cast film can be thinned by winding the film out of the roller faster than it is extruded. http://www.xinyemachinery.com/film-blowing-machine/
