20,000 pcs/h PET Preform High Speed Injection Molding Machine

Zhangjiagang Dawson Machine Efficent series high speed injection molding machine, is specially designed for PET preform production.

As the competition in the PET preform market becomes more and more intense, and the profit becomes less, the transformation and upgrade of the preform production process and cost control have become the top priority to all PET relevant products manufacturers.

The two core factors that restrict the production cost of preforms are the cycle time and energy consumption. Therefore, the requirements for the cycle time and energy consumption of the PET IMM getting higher and higher.

But most of the injection molding machines in the market are for general-purpose products, only by simply changing the screw& barrel unit to use for preforms. They are not specially designed for PET preform mold and PET material.

Our EFFICENT series injection molding machine is focusing on high-speed preform injection molding system, these special high speed PET injection molding machines can help our clients solve this difficult problems from the root.

Efficent series machine adopt electric premolding technique, it maintains plasticizing process during mold cooling, so as to increase production capacity. Our cycle time is only around 10 s/shot based on 48 cavity preform mold for small preforms, such as 13~15g regular size water bottle preforms.

We also adopt servo motor to help you save energy cost.

      Our Advantage                                        


Oil-electric hybrid high-speed preform injection molding machine.Special injection molding machine for fast preform.The whole machine adopts the design style of European style, and the appearance is beautiful and high-end.

The safety door glass is made of PC board    material, which has good strength and high transparency, while most of the injection molding machines in the same industry use acrylic board, which has poor strength, vulnerable parts, and poor transparency.

The blanking plate is heightened with two water pipe perforations, which is convenient for connecting the water inlet and outlet pipes

of the mould.

For models above 320 tons, the base of the pallet is lengthened to allow the weight of the reducer to be distributed on the base.
Otherwise, the reducer of a large preform machine is heavy and the weight is distributed on the drive shaft, which is easy to  deform and break. (Exclusive design of EFFICENT type)


The solid state relay is used, which has a long service life, while most injection molding machines use thermal contactors, which are

easily damaged due to the high frequency of opening and closing.

The casting of the direct injection table is specially set at two supporting points to prevent the molten glue servo motor from
sinking due to its own weight, which will cause the drive shaft connecting the motor and the reducer to break. (Exclusive design
of EFFICENT type)

The surface of the injection machine frame is sprayed with patterned iron plate, while the domestic injection molding machine uses
patterned aluminum plate, which avoids the high-temperature hot material when starting and stopping, and the cleaning material is
easy to deform and warp when it falls on the patterned aluminum plate, and the patterned iron plate has strong high temperature

resistance , to circumvent this problem.
