    • The present invention is directed to a device for the production of a cellular wood plastic composite material comprised of an orifice that conducts the composite material from the adapter of the extruder (12) to the transition die plate (30) in such a manner that a uniform flow of material reaches the transition die plate; a transition die plate that further directs the flow of material to a flow restriction die plate (60) in a manner ensuring that equal amounts of material are delivered to all areas of the flow restriction die plate; a flow restriction die plate that provides sufficient resistance to material flow to increase the melt pressure of the portion of the material that is upstream in relation to the flow restriction die plate and controls the temperature increase caused by this restriction by dividing the flow into numerous suitably sized and shaped streams; a compression die plate (70) that fuses the separate streams issuing from the flow restriction die plate into a single stream of material and maintains the melt pressure at a level which will prevent premature development of cells in the material; a shaping die plate (80) that is designed to shape the material in such a way that the fully expanded material will approximate the shape of the desired profile and to control the rate of cell development and expansion so that large numbers of uniform cells are produced.
    • 本发明涉及一种用于生产细胞木塑复合材料的装置,该装置包括将复合材料从挤出机(12)的适配器传导到过渡模板(30)的孔口,使得 均匀流动的材料到达过渡模板; 过渡模板,其进一步引导材料流到限流模板(60),以确保相等量的材料被输送到流动限制模板的所有区域; 流动限制模板,其提供足够的材料流动阻力,以增加相对于流动限制模板的上游的材料部分的熔体压力,并通过将流量分成许多适当的方式控制由该限制引起的温度升高 大小和形状的溪流; 压缩模板(70),其将从流动限制模板发出的分离的流熔合成单个材料流,并将熔体压力保持在将防止材料中的细胞过早展开的水平; 成形模板(80),其被设计成使材料成形,使得完全膨胀的材料将接近所需轮廓的形状并控制细胞发育和膨胀的速率,从而产生大量均匀的细胞 。
