iPET High Speed Preform Injection System

  1. Independent electric screw drive brings you both melting and energy efficiency
  2. BECKHOFF centralized control system special designed for  PET production.
  3. Three station post cooling robot makes the preform perfectly cooled with better cycle time.
  4. Advanced servo valve control technology makes the highly dynamic injection possible.
  5. Up to 5 sets of high efficient accumulator ensure the stability of high capacity injection .
  6. Synchronous material melting,plasticization and injection at the same.
  7. Special design for PET preform mould,which ensure the fast clamping movement and uniformly forced of the mould.
Demark iPET high speed preform production system 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 144 cavities which including double screw design high speed injection 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. You can also choose MHT preform injection molds from Germany at the same time. Demark also insist on the “turnkey” solution concept by offering preform design and whole plant planning to our customers with more suggestion on various aspects to help our customers keep long term competitive strength in the hyper competitive, changeful consuming market.
