ECO series high speed preform injection molding machine

Best seller PET preform injection machine, can work with different bottle preform mould

Demark brings you the ECO series high efficient preform injection system with many years' innovation. The system is up to 72 cavities and double production capacity with normal injection machine. With the advanced pressure hold technology, the system makes the palsticization and pressure hold at the same time therefore has a better cycle time for production. With Demark precision preform injection molds, post cooling take out robot, centralized control system and high efficient material drying system, the ECO series brings you more returns with limited investment.

The ECO series PET preform injection machine is specialized for preform production with enlarge screw and fast clamping design. The sytem is widely used for water and beverage preform production as well as big gram preform such as oil and 5L water proform. Demark also insist on the "turnkey" solution concept by offering preform design and whole plant planning to our customers with more suggestion on various as pects.

Why choose ECO series injection machine

cycle time

Totally change the way of PET preform production
Excellent system design, makes all the parts works togethor under the central system and greatly reduce the cycle time. 15g preform with 48 cavities system cycle time 9s. 100g preform with 24 cavities system cycle time 23s.

Reduce your initial investment

Reduce your initial investment
With almost the same producing efficiency as the high speed machine, the investment of ECO become great advantage. The PET preform injection machines help the customers gain more production capacity with limited investment and grab the market in advance.

different preform mold

One ECO machine can work with different bottle preform mold
72 cavities, 15g preform, for 500ml water. 48 cavities, 34g preform, for 1.5L water. 25 cavities, 103g preform, for 5L water and edible oil.

Technology

electric screw drive

Electric screw drive
Independent electric screw drive brings you both plasticization and energy efficiency.

BECKHOFF control system

BECKHOFF control system
Brand new BECKHOFF centralized control system special designed for PET bottle production. The project is leading by Mr.He-former HUSKY engineer who was in charging of the developing preform injection machine control system. Applied with his new generation PC based BECKHOFF injection system control solution.

Post cooling take out robot

Post cooling take out robot
Three stations post cooling robot makes the preform perfectly cooled with better cycle time.

Proportional valve control

Proportional valve control
Advanced proportional valve control technology makes the fast and precise clamping possible.

Servo motor drive hydraulic system

Servo motor drive hydraulic system
The hydraulic system was driven by a servo motor which ensure the lower energy consumption and sufficient hydraulic power supply.

Pressure hold valve

Pressure hold valve
With the advanced pressure hold technology, the PET bottle injection moulding machine makes the plasticization and pressure hold at the same time therefore has a better cycle time for production.

Reliable clamping

Reliable clamping
Special design for PET preform mold, which ensure the fast clamping movement and uniformly forced of the mold.

HCI control system

HCI control system
BECKHOFF centralized control system special designed for PET production.
