PET plastic injection molding machine is special designed and manufactured according to PET material moulding technologies, such as the special design of the screw and barrel, precision controller of the heating of the barrel, tie-bar space, nozzl, ejecting system, enlarged motor and oil pump, etc. Various types of pet preform including pet bottle preforms, hot fill bottle preforms, wide mouth jar preforms and 3-5 gallon bottle preforms.
NPC Precision Machinery has rich experiences in various types of PET preforms manufacturing process technology. We design the Pet preform injection molding machines aim at preforms or other PET products, offering an optional choices. We go through all the factors like: raw PET dehumidification, additive color mixing, production capacity, stable running, even connect with the blow mold machine or other next step, then NPC will provide you the professional turnkey solutions meet with your budget and request.
Our PET preform injection molding machine is suitable for forming preforms of mineral water, carbonated drinks, fruit juices, edible oil, medicine cans and lotions, cosmetic packaging containers and other product preforms.
