* Splicing structure, easy to transportand disassemble with simple and elegant appearance.
* Using food-grade PP material,healthy, environment friendly and making no slag or other contaminant to the preforms.

Oven

In the oven the preforms move forward and rotate themselves to make every part of the bottle have the same temperature. After heating, the preforms have elastomeric property, so the preforms can be stretched biaxial. For the soft drinking bottles the range of temperature is 90~100℃, while for hot filling bottles the range is 110~120℃. The heat of the oven is controlled by the quantity of the working lamps, the whole setting temperature and the power of the oven.
