Machine Features:
1. Quantitative Lubrication Volume Distribution System
Make sure every lubricating point be fully lubricated, oil distribution uniformed, and higher lubrication efficiency. It greatly improved the working life of the lubrication parts.
2. Special Ejector Rod Structure Design
Make it quite convenient to install counter pull ejector rod, so it greatly extends the adaptability of the machine.
3. Built-in Mechanical Safety Bar
Built-in mechanical safety bar, more beautiful and safer.
4. Larger Space between Tie-bars
Larger space between tie-bars and larger opening stroke can realize the easy installation of multi-cavity mould, and it has better adaptability for the increasing precise mold dimension
5. Paralleled Double Carriage Cylinder
Paralleled double carriage structure, avoid nozzle moving left and right, avoid melt leaking out on the touching surface.
6. Double Injection Cylinder
Double cylinder injection system, ensure the stable and precise injection; Adopt self-lubrication copper bushes, high speed and low friction; Standard with high quality SKD61 screw tip, check ring and thrust ring, 38CrMoAl screw and barrel, wonderful plasticization and long working life.
7. Double Linear Guide Rail
Double linear guide rail, faster speed, more precise and stable.
8. Energy-saving System
Adoption of servo motor and internal gear pump power system, realized the power output mode of "energy how much needed, how much given". It avoids energy waste, and the energy-saving ability can reach to 20%-80% comparing with the traditional power output mode.
9. High Precision Controller
It requires only 0.05sec to reach the maximum power output, cycle time is substantially shortened.
10. World Famous Brands Hydraulic Parts
Adopt world-famous brands of hydraulic parts, ensure machine's precision, durability and stability.
11. Proportional Back-pressure Control
Melt back pressure adopts injection proportional back-pressure control, so the process adjustment range is wider and the product is more stable.
