(1) raw materials are required to meet the functions, performance (medicine, food packaging) requirements of blow molding products. The raw materials of the blow molding stage will be more abundant and the processing performance will be better.Materials such as PEN, not only high strength, good heat resistance, gas barrier property of strong, transparent, resistance to ultraviolet radiation, can be applied to blowing plastic bottles, and fill the temperature is high, the carbon dioxide gas, oxygen barrier, excellent performance and resistance to chemicals.
(2) the product packaging container and industrial products will grow greatly, and the injection blow molding and multi-layer blow molding will develop rapidly.
(3) precision and high efficiency of blow molding machinery and equipment blowing machine;Automation of auxiliary production equipment."Precise and efficient" not only refers to the mechanical equipment in the production of molding process has high speed and high pressure, and the production of products in terms of fluctuations and a heavy appearance size all can achieve higher stability, that is to say, the size and shape of each place production products high geometric accuracy, deformation and narrow, product appearance and inner quality and production efficiency of indexes to reach a higher level.The auxiliary operation includes flying edge, cutting, weighing, drilling, leak detection, etc., its process automation is one of development trend.
(4) more deeply the researches on the mechanism of the blow molding simulation of blow molding, blow molding simulation mathematical model of reasonable construction, numerical algorithm of the rapid, accurate is the key to simulate.
