48 Cavity PET Preform Plastic Electric Injection Molding Machine

Zhangjiagang Dawson Machine is a company integrated plastic machine & molds design, production and sales. We’ve started plastic machinery business since 2003.


Efficent series high speed injection molding machine is specially designed for PET preform production. The PET injection volume / weight is higher than other brand machines of the same tonnage. It allows you to produce more cavity and heavier preforms.

The preform market competition is more and more intense, using our high speed PET preform injection machine, you can upgrade your production, increase competitiveness.


Our machine also use electric premolding, this function will keep the plasticizing process while the mold is cooling down, in this way, the machine’s speed is much approved.


Take 500/550ml, 12.8g-16g gram weight, and 48-cavity preform mold for example, the output capacity of our EFFIENT series injection molding machine is about 20% higher than that of competing products of the same model in the market. The output of preforms is about 700 kg more per day, and the output of preforms per month is about 21 tons. Calculated at a profit of US$80/ton for PET preforms, each month you can have US$1.615 more profit with Dawson Solution.


4 second faster, 20% extra profit. 

      Our Advantage                                       


The double-injection structure is adopted to ensure the stability of the forward and backward movements of the injection platform.

The standard high-quality ceramic heating ring has good heat preservation effect, avoids large temperature deviation from affecting the PET bottle preform molding process, and has a long service life.

Between the safety door sheet metal and the pc transparent board, a special UV process is used, and a black frame is added around
it to increase the overall aesthetics. (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.
