Clear double color(double shot) injection molding machines

Product name：Clear double color(double shot) injection molding machines

Series：Double shot molding machine

Function Introduction：
Double nozzle in seperate direction; double hopper; double injection unit;

Description：

A: Clamping system:
1. There are four section clamping speeds including fast and slow with lower power consumption, stable, low noise;
2. Low-pressure mold protection function, both mechanical and electric interlock safe guarantee;
3. Central hydraulic ejecting, jolt ejecting, back ejecting and multi-ejecting can be realised, speed and pressure can be regulated;
4. Four cylinders direct clamping assure that the mold is stressed evenly;
5. Double differential mold movement, dispense with need for liquid lubrication and adjustment;
6. The opening and closing stroke is precise in repeatition by using linear ruler control;
7. Super sensitive low pressure mold protection;
8. The world famous brand of high pressure resistant seal components and standard high precision cylinders are assembled;
9. The strokes for ejector and mold movement are lengtheneed; oil pressure safe protection device is available;
10. Twin loose-core oil circuit, mechanical arm and rotary striper can be chosen;
B: Injection system:
1. High-power duplex cylinders injection;
2. Torque hydraulic motor imported from Italian famous brand;
3. Four sections injection pressure and speed, three sections presssure and speed for pressure holding;
4. Multiple auto temperature control by computer and fault indication-detector are available;
5. Nozzle plugging and spew can be detected automatically;
6. The prevention function with low temperature alarm will stop a fault start in case the material is in an insufficient temperature;
7. Back pressure can be regulated, empty hopper alarm will and spew suction prevention function are available;
8. Precisely linear position transdusor can control injection stroke;
9. The screw and barrel are made by high-grade alloy 38CrMoAIA with nitride wear-resistant treatment to ensure the quality and service life;
10.PID (proportional integral differential coefficient) temperature control;
11.Bimetallic screw and barrel;
12.Hydraulic control injection nozzle;
13.Power storage high-speed injection;
C: Control system:
1. The electric aparatus and hydraulic parts are world famous brand;
2. The pressure and speed are controlled by proportional pressure valve and proportional flow valve;
3. The control computer is world famous brand;
4. Self-diagnosis function;
5. Data such as pressure, speed, time, stroke and temperature can be input directly;
6. LCD display;
7. Production quantity, auto-stop and alarm can be set up;
8. The movement of ejector and injection stand controlled by an electric ruler can be choosen;
9. Injection melting, opening and closing can be controlled by a close-loop system;
10 Various-delivery pump or converter is adopted;
