  1. Introduction to JUII⊕Series Machine

  2. Machine overview More clean Oil-free or less oil lubrication technology Shorter dry cycle time New planning of mold clamping and clamping cylinder’s diameter Better structure of clamping unit Tie bar suspension to reduce loading More safe and beautiful gate Standardization improved More stable and reliable running Mold opening and clamping proportional valve technology improved

  3. Platen Structure changes： • Mold weight increase 10% than JUII series machine； • Back improved； • Stronger X direction； • Big plane upward when pouring process； L3 Performance improvement： • Platen deformation reduces 15%, maximum principle stress reduces • Platen rigidity enhances and machine life prolongs； 3. Better protection for mold, reduce its wearing and prolong lifetime； L1 L2

  4. Tie bar Structure changes ： • Tie bar suspend without guiding, no touch with movable platen； • Bar diameter 10% thicker； • Design of tooth-type clamping； Performance improvement ： • No scraping between tie bar and movable platen； • Mold opening and closing loading reduce, less energy consumption； • Tie bar rigidity enhances and lifetime prolongs； • Strength of clamping tooth increase, its error tolerant rate rises； JUⅡ JUⅡS

  5. Rapid mold moving cylinder Structure changes ： • Improve the cylinder diameter up to the real machine loading； • Redesign the cylinder structure with the international advanced solution； • Improve proportional valve control for oil-in and back when mold opening and clamping ； Dry cycle time JU16000Ⅱvs JU16000ⅡS Performance improvement ： • Higher mold opening and clamping speed and shorter dry cycle time； • Quicker response of mold opening and clamping, more stable running； • Better mold opening and clamping positioning precision and repeated accuracy； • Better structure and reliability

  6. Lubrication JUⅡ Structure changes ： • Oil-free self-lubrication for fixed platen and brake； • Self-lubrication for movable platen gliding foot, very little lubrication oil； • Improve lubrication specification Performance improvement ： • Machine more clean； • Oil-free or less reduces cost； • Reasonable lubrication frequency provides better protection to machine lifetime.

  7. Electrical unit JUⅡ JUⅡS Structure changes ： Built-in positionsensor of mold clamping cylinder Performance improvement ： More accurate zero position, much lower deviation rate, and more reliable position precision

  8. Electrical unit Structure changes ： Technological structure of heating cycle improve； Performance improvement ： Heating efficiency of heating ring enhance； Old heating ring New heating ring

  9. Controller Controller types： Performance improvement ： • New design for Haitian panel, more humanization and easier to operate • Better CPU performance and bigger internal storage • More onboard I/O • More interface like EtherCAT，CANOpen，serial port etc.

  10. Hydraulic system Structure changes 1.Clamping pressure rises to 210bar； 2. Pressure holding motor uses variable pump； 3. Equip two pressure holding functions: energy-saving and persistent； • Performance improvement • Diameter of mold clamping cylinder is decreases and dry cycle is shortened； • Energy consumption of mold clamping and pressure holding is more reduced；

  11. Hydraulic system Structure changes ： Cancel by-pass oil filter, change to separate filter JUⅡ JUⅡS Performance improvement： 1.The separate filter has blocking detection sensor which has automatic alarm, while by-pass filter has no such function； 2. Stronger filtering ability, cleaner oil, longer hydraulic lifetime and better performance；

  12. Hydraulic system Structure changes ： Optimize tie bar reset program and increase tie bar speed control valve Performance improvement ： 1.Tie bar reset speed is controllable and brake has better reliability；

  13. Machine body Steel belt design improve 1. Thickness increase: use 3mm belt;2. Fixing types change； Performance improvement ： • Abrasion performance enhance, lifetime prolong. • Anti-curl ability enhance to provide accidental break

  14. Safety Gate Overall planning： 450T-750T up and down pathway gate 900T-1850T floor type gate without up pathway 2100T-4000T Aluminum frame gate

  15. Hot runner Structure changes 1.Integrated form 2.Compact wiring； • Performance improvement • Easy insert and pull out； • Small signal degradation； • Better compatibility

  16. Material-feeding platform Structure changes ： Machine 1400T above adopt retractable aluminum alloy ladder Performance improvement ： • Easy operation and more beautiful； • Accord with national safety standard and CE etc.；
