Hollow molded product raw material equipment and application

China molding (blow molding) products are products made from HDPE and PET, including various bottles, barrels, agricultural and agricultural containers, industrial products such as automobile fuel tanks, and marine floats. PET is mainly used for small beverage bottles and food bottles. LDPE and LLDPE are only suitable for small, daily-use containers and flexible packaging. Extrusion blow molding machine large and medium-sized blow molding products generally only use HDPE as raw material. In the blow molding market of HDPE consumption structure in the three major regions and countries with developed plastics industry in the United States, Europe and Japan, European HDPE blow molding products account for about 38% of HDPE total consumption, while the United States is about 34%, just like Europe. The market with the largest share of HDPE consumption, Japan is mainly based on film consumption, and blow molding products account for about 15%. The consumption structure of HDPE blow molding products in the United States is: liquid food bottles are the largest, accounting for 31.8%, followed by household, industrial and cosmetic bottles, accounting for 22.8%, industrial barrels ranking third, accounting for 7.2%, and fourth is motorcycle oil. Bottles accounted for 6.4%, others accounted for 29.1% (tool kits, garbage cans, industrial parts, automotive fuel tanks and other automotive parts). Industrial barrels are used for chemical goods, lubricants, coatings, cosmetics and other packaging. There are different types such as wide mouth and square mouth barrels. The cover is made by injection molding. The development direction of extrusion blow molding machine is multi-variety, diversified and professional. Large-scale, multi-layer coextrusion and large and medium-sized containers are developing relatively fast.
