2 Cavity Bottle Mould
PET containers are manufactured in a single-stage or two-stage process. The single-stage process combines the injection and blow moulding processes of preforms. The two-stage process has separate injection for the preforms, and separate blow moulding in which the preform is stretched and blown to its final shape. In many cases more than one technology is used. The technologies are all patented and proprietary, employing different barrier materials and processes to reach the best solution.
The mold is one of the important components of the second stage, with two cavities, which greatly improves the production efficiency. Mold materials are produced according to customer needs, Mould material：45#, 50#, P20, H13, 718, 2738, NAK80, S136, SKD61 etc.and blow molded parts can be made from a variety of thermoplastic materials, including:
Low Density Polyethylene (LDPE)
High Density Polyethylene (HDPE)
Polyethylene Terephthalate (PET)
The bottle body of the produced product is added with texture design, and the screw mouth at the bottle mouth is designed with good sealing and no air leakage.
