    Detailed Product Description

    EA series 2-component elastomer casting machine, dosing machine, mixing machine

    1. Summary:

    Our pu casting injeciton machine is that our company follows the international advanced technological products, imports the main machine parts from foreign countries and famous brands. Hence, technical and safety performance of the equipment has reached the advanced level of the same product of the same period abroad.

    This machine is used for producing casting polyurethane elastomer product which use MOCA and other material as chain extender, such as gluing roller, pad, rollers for elevator use and highly rigid products and can compose pre-polymer and vacuum defoaming in this machine.

    Different PU rubbers can be switched instantaneously to produce CPU of different materials.

    2. Main parameters and descriptions for the equipment

    Max Temp: 130℃

    Tolerance on the temperature holding: Within +/- 1.5°C

    Mixer: Stainless steel material ,anchor type

    Mixing speed: Adjusted according to different raw material

    Inspection window: Glass window in the tank body

    Option: Electrical inductor

    Auxiliary System:

    Vacuum system

    Nitrogen filling system

    Vacuum meter

    Raw material filling system

    Raw material vacuum absorb system

    Raw material unloading system


    3.2 Pipe

    Material: PTFE reinforced stainless steel with mesh

    Heating system: OIL heating

    Max working pressure: 20 bar

    Max Temp: 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

    The heating system: independent electrical heating

    Temperature measurement system: PT100 thermal sensor

    Temperature error: control +/- 1°C

    Each injection pressure control is independent of each other, can be adjust alone pressure casting and recycling pressure. The loop injection pressure will be tested by the head of sensor, and with pressure adjusting device. This control method can avoid every time before pouring out some materials must be mixed and the uneven.

    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

    leaning 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.
