JASU 4-stations Automatic One-Step injection stretch blow molding machine for PP Baby Feeding Bottles
Product Description
The machines are 4-stations, injection preform, preform heat, blow/stretch blow and product release. The raw material comes from the hopper to the injection screw to inject preform; preform heat; the plate rotates preforms to blow/stretch blow station with themselves heat, without any reheating for blowing, Then the product will rotate to release station and drop down, it is fully automatically cycle rotation working mode.
One of the major advantages of injection stretch blow molding is the ability to stretch the preform in both the hoop direction and the axial direction.This biaxial stretching of material increases the tensile strength, barrier properties, drop impact, clarity, and top load in the container.With these increases it is usually possible to reduce the overall weight of a container by 10 to 15% less then when producing a container in another way.
Lower investment cost for equivalent output Since this process does not require secondary heating, with the help from servo-driven injection system, this bottle manufacturing machine is able to save up to 40% in energy consumption while improving the overall output by 25%.
High quality injection molded neck finish bottle screw size of neck and bottle parting line are perfect, bottle is stronger. No need secondary heating preform,along with energy saving system, can save about 30% power.Automatic production, no need to remove burrs, no need to transport preform, greatly save raw material and labor costs. Stable performance with advanced PC.
Strong clamping force with high pressure and double crank links to lock the mold .Hot runner with valve gate type, designed with special anti-leak device, is adopted for higher preform gate finishing.
