The EPY650-V4<\/strong> is the heavy industrial leader of the EPY series. Weighing in at 28 Tons<\/strong> and boasting a 400KN clamping force<\/strong>, it is engineered for the massive production of large-volume containers, such as 5-gallon PC water barrels, 20L edible oil containers, and wide-mouth jars.<\/p>\n<\/div>\n The EPY650-V4 integrated blow molding machine<\/strong> is designed to handle the toughest molding challenges. Its massive platens and extended stroke (1070mm upper \/ 550mm lower) allow for deep-draw containers that smaller machines simply cannot produce.<\/p>\n Whether you need to produce a single 20L PC water barrel<\/strong> or four 5L PET oil bottles<\/strong> per cycle, the EPY650-V4 delivers consistent wall thickness and high optical clarity, free from the hazing often seen in two-step processes.<\/p>\n \ud83d\udcaa Heavy-Duty Specifications:<\/strong><\/p>\n The EPY650-V4 utilizes a 4-station rotary table<\/strong> system that rotates 90 degrees every cycle. This integrates the entire production line into one compact unit, ensuring energy efficiency and superior bottle quality.<\/p>\n Molten plastic (PET\/PC\/PP) is injected into a cooled mold to form the preform<\/strong>. The neck finish is molded to exact tolerances here, ensuring a leak-proof seal for the final cap.<\/p>\n<\/div>\n The hot preform is transferred here for temperature equalization. Heating pots or cooling rods adjust the preform’s thermal profile, which is critical for blowing uniform walls in square or oval containers<\/strong>.<\/p>\n<\/div>\n The conditioned preform is stretched axially by a rod and expanded radially by high-pressure air (up to 3.5 MPa). This biaxial orientation significantly increases the bottle’s strength and clarity.<\/p>\n<\/div>\n The finished bottle cools and is automatically ejected onto a conveyor. Since the bottle never touches the floor or manual handling during forming, it remains pristine and scratch-free.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n (Swipe left\/right to view full table on mobile)<\/p>\n
