    • A weather strip manufacturing method for vehicle using the supercritical extrusion system is provided to be recycled and fire retardant since the environment-friendly thermoplastic elastomer material is used. A weather strip manufacturing method for vehicle using the supercritical extrusion system comprises following steps: a step(S10) for inputting thermoplastic elastomer; a step(S20) for inputting the supercritical fluid which has the property of the fluid and property of the gas at the same time; a step(S30) molding through the molding extruder for uniformly diffusing with the thermoplastic elastomer and supercritical fluid; a step(S40) for transferring the weather strip extruded through the molding extruder and outputting to outside. The molding extruder is comprised of an exclusive screw internal pressure cylinder and an exclusive dice. The step for outputting the weather strip to outside includes a step for extruding the melted resin through the V-shaped head for the extrusion.
    • 提供使用超临界挤出系统的车辆的防风条制造方法,由于使用了环境友好的热塑性弹性体材料,因此被再循环和阻燃。 使用超临界挤出系统的车辆的防风条制造方法包括以下步骤:用于输入热塑性弹性体的步骤(S10) 用于同时输入具有气体的流体性质的超临界流体的步骤(S20); 通过成形挤出机对热塑性弹性体和超临界流体进行均匀扩散的步骤(S30)成型; 传送通过成形挤出机挤出的耐候条纹并输出到外部的步骤(S40)。 成型挤出机由专用螺杆内压缸和专用骰子组成。 用于将耐候条输出到外部的步骤包括通过用于挤出的V形头挤出熔融树脂的步骤。
