Twin Cone of a multi-positioning technology, each cavity clamping a single independent, multi-level taper positioning system to ensure that mold concentricity (eccentric within the 0.05-0.06 mm). Mold cavity, the core optional S136 (Sweden imports) and 718 high quality steel or stainless steel (hardness> HRC45). I thread in accordance with international standards manufacturing, material selection steel imports nitride (hardness> HRC60). Unique system to ensure that the heat all the same cavity pressure and flow than PET.
