DP series high speed preform injection molding machine

Demark DP high speed PET preform injection machine allows you gain the same level of specification as European machine but with lower investment cost at the same time. The system can produce with the preform injection system can peoduce with the preform injection molds up to 96 cavities which including double screw design high speed injection moulding machine precision preform injection molds, post cooling, take out robot, centralized control system and high efficiency material drying system. The results are higher production efficiency, and better preform quality.

Demark holding group also insist on the "turnkey" solution concept by offering preform design and whole plant planning to our customers with more suggestion on various aspect to help our customers keep long term competitive strength in the hyper competitive, changeful consuming market.

Technology

Electric screw drive
Imported servo motor sol has brought energy saving and high efficiency double improvement.

Synchronous melting
Synchronous material melting, plasticization and injection at the same.

Reliable mold-locked
The template structure specially designed for PET preform mold is that all parts of the die are uniformly stressed, while ensuring the requirements of high-speed die opening and closing die.

Post cooling take out robot
The double stage post cooling robot makes the preform perfectly cooled with better cycle time.

THK linear guide
With the optimized PET special hinge parameters, the opening and closing die is fast and stable.The second board and the pull rod are completely disengaged, and the second board is supported by THK  linear guide, which has samll resistence and saves energy.

High efficiency accumulator
Up to 5 sets of high efficient accumulator ensure the stability of high capacity injection.

Servo valve control
Advanced servo valve control technology makes the highly dynamic injection possible.

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