1. Feeding system:
Specially made screw is used to achieve optimal exhaustion for the material. Heating oil is circulated to avoid jamming while increasing the feeding speed and stabilizing the temperature of the fed material.
2. Injection system:
 German made resistance scale, and “cc” is used as the measuring unit. The temperature is controlled by circulating heating oil to achieve accurate injection.
3. Cold runner mechanism:
The sliding plate system is used to separate the injecting and curing function. Cold rubber compound is used for injection, and curing process is on the other plate to achieve almost zero waste material after injecting molding.
4. Monitoring design:
Full-area design to monitor the machine operation, pressure, flow rate, warning sign and warning record.
5. Hydraulic circuit design:
Proportional Pressure and flow ratio system is designed for easily changing the pressure and speed setting.
6. Electrical control system:
6-1. Precise temperature controlled is using PID calculations, temperature can be adjusted by connecting the man-machine interface.
6-2. The module saving function includes temperature, pressure/flow rate, time, injection position, ascending/descending position, and function settings.
6-3. Heating system: using SSR solid relay with fast heat-up without exceeding the limit.
6-4. Mold adjustment: slow mode adjustment function is provided. Simply to press up/down key to complete the mold position setting.

1.Contrast of waste materials:
The slide plate is kept at constant temperature range of 60℃~80℃, therefore it can avoid rubber materials being wasted in the mold and injector head.
2.Contrast of Mold:
Only simple modification needed to make on regular injection mold, and make a new plate for pressing to achieve the best result. 
3. Contrast of mold installation:
Regular injection mold can be directly used on Cold Runner Rubber Injection Machine, there’s no need to install extra cooling pipe.
4. Contrast of producing products: 
Every rubber products made by a regular rubber can be produced on cold runner rubber injection machine.
5. Contrast of saving materials: 
The more canal / channels / runners your mold has, the more rubber materials you can save (about saving 30-100cc /sheet).
