Temperature control of plastic bottle processed by blow moulding machine

Plastic bottle processing with blow molding machine This is a common processing project in plastic processing, so where is the focus in this process? What I'm going to tell you is that temperature and temperature are critical to the processing of plastic bottles. In the operation of the hollow blow molding machine for processing, we must pay attention to some temperature control to ensure the production of suitable plastic bottles.

Non-flowing temperature: the maximum temperature at which no flow occurs under certain pressure. is to add a quantity of plastic to the upper end of the capillary rheometer in the barrel, heating to a certain temperature, constant refresher 10MIN, the imposition of 50MPA constant pressure, if the material does not flow from the mouth mold, unloading pressure will increase the difficulty of the material temperature 10 degrees, heat preservation 10MIN and then apply the same size constant pressure, This continues until the melt flows out of the die, reducing the temperature by 10 degrees is the flow temperature of the material. Flow temperature tf: A temperature in which the amorphous polymer is converted from a high to a viscous state. is the lower limit of the processing temperature of amorphous plastics.

Decomposition temperature TD: Refers to the polymer in a viscous-flow state when the temperature increases further, the degradation of the molecular chain will increase, the temperature of the polymer molecule chain degradation when the decomposition temperature. Melting Temperature TM: For crystalline polymers, the three-dimensional remote ordered state of macromolecular chain structure is changed to the temperature of disordered viscous flow state, also known as melting point. It is the lower limit of temperature of crystalline polymer forming process. TG: Refers to the transition temperature of amorphous polymers (including crystallization of crystalline polymers) from glassy to high or from the latter to the former. It is the minimum temperature of free movement of the amorphous polymer chain and also the upper limit of the working temperature of the product. More content Welcome to inquire.
