    XPS foam board

    XPS Foamed Board, also named as expanded polystyrene extruded board (XPS for short)it is a kind of thermo insulation board made of polystyrene and foaming agent and extruded at high temperature.


     

    Multi-group mixed distribution system
    Computer controls the ratio of various raw material, use weightless accurate measurement, mixed materials with strict provision, use vacuum feeding system to ensure the stable delivery of raw materials. All these factors lay the foundation for high quality pipe production.

    Extrusion system

     

    The CO2 XPS extrusion system uses a parallel twin-screw extruder .the screw is block type structure, use different combination  to match material processing. The connection is special designed. the transmission device enhances the strength of the threaded element and the mandrel to get evenly material dispersion and well-mixed.

     


    Cooling system

    The cooling system applies precise proportional control , equipped with a high-power chiller to achieve the best cooling effect, meet the harsh requirements of the cooling system in the production process.

    Supercritical CO2 foaming agent injection system

    The supercritical CO2 foaming agent injection system adopts an all-inlet flow control system to precisely control the instantaneous volume flow and mass flow of the foaming fluid, and design a closed-loop control program to maintain the stability of the mass flow rate. The unique three-stage pressurized injection system maintains a stable CO2 liquid phase state, ensures the formation of a homogeneous system, and uses an automatic flow feedback control system to maintain the stability of the foaming agent flow.

     

    Extrusion die, calibrating system

    The extrusion die is based on the rheological characteristics of low temperature and high viscosity of PS physical foaming materials. T-type large manifolds and long sector area noses are used for pressure extrusion. The circulating system oil is thermostatically controlled and the PID intelligent temperature control modules form a closed-loop control system, which can accurately control the mold temperature within the process requirements. Molding system has bi-directional electric adjustable device, which achieve proportional control of low-resistance system material, double-sided shape.
