最高溫度：130℃
Tolerance on the temperature holding: Within +/- 1°
These high flexibility insulation pipe can ensure the consistency of temperature in the whole pipeline.
3.3Metering system(A,B, components)
Metering pump: Gear pump from German
Delivery capacity of Metering pump: A 40cc/r, B 6cc/r
Filters: Highly filtering surface Stainless steel 304.
Motor:Converter in accordance with tachometer and motor to control the flow speed.
ALL the metering system and fliters keep under the tank and within the heating
The measurement system and filter in ovens, insulation material below. This design method can be pressurized tank in the wrong circumstances, to maintain sustained and steady output of raw materials; and keeping the consistency of the temperature. Computer will be set to control output of the wheel pump. This control system can ensure that the output of raw materials in the setting value of + / - 0.3% .
3.4 Mixing head
Material: High strength alloy
Speed: 0.0 to 6500 rpm.
Heating: Independent electrical heating Mixing by mixed-head match with the motor
Temperature check: Thermal sensor.
Tolerance on the temperature maintenance: +/- 1°C
Motor: Electric motors, controlled by a frequency convertor.
Our uniquely mixing head design has the following features: It can guarantee the accuracy of speed, and at a very low speed of the mixed quality of raw materials; so that the prepolymer does not cause pressure damage to properties.
Made of special alloy mechanical seal system made the mixing head also could work in the high anti-pressure, while ensuring the reliability of mixed system.
Unique design of the mixing chamber can be cleaned to ensure easy-to-use and thoroughness.
3.4.1 Injectors for A,B,
Material: high strength alloy
Injection system: injection pressure independent of each other

Injectors: Single for each auxiliary with independently adjustable injection pressure.
4. Cleaning system
Tank:20L Stainless steel
Control of Liquid :Visual glass window
Low position warning electronic equipment (OPTION)
Injector: Inject raw material to mixing head directly
The running speed and circulation of cleaning solution,air,mixing head are are independent control system,this can make them aximum cleaning effect.
In order to the maximize reduce consumption of cleaning, settings of each component can be pre-cleaning procedures. The casting machine Settings when suddenly loses power in the artificial emergency cleaning device. Cleaning solution should use non-flammable solvents, such as:DBEMC
5.Electric Board and software
Electronic display design according to the EC criteria.
Software: The software system can control the machine to work and in the standby machine control.
Data in the user interface through the following procedures:
* Working state real
After all the machine on real-time parameters can be displayed on the interface, such as temperature, pressure, pumping and mixing speed, security levels, alarm conditions and other procedures set by the parameters must be displayed.
* Formula design program
The major setting and save the formula interface ( depth, temperature, pressure, etc). For each formula can be set and save 20 subroutine, these subroutines can cast the first one near the selector out directly.
* Calibration interface
This interface is mainly used to automatically correct out of three different charge, by a balancer to determine quality.
The software also include some other systems, such as casting machine maintenance control, work time, data statistics and alarm records. Computer software must pass a set of passwords or keys in order to start, this can guarantee the authorized person is different for different levels of machine control.
