The invention discloses an automotive PET profile air duct and a manufacturing method thereof, and belongs to the technical field of automotive interiors, and the air duct comprises a PP air outlet, a PET pipe body and an HDPE connector; an air inlet port of the pipe body is connected with the connector, and an air outlet port of the pipe body is connected with the air outlet. According to the invention, the PET profile with the thickness of 10-14mm and the density of 400 +/-10g/cm < 2 > is produced through the development of hot press molding and a welding process, and the PET material is used for replacing a PP material used in a traditional air duct, so that the assembly applicability, the aging resistance and the combustion resistance of the whole air duct are effectively improved, and compared with the existing air duct with the same specification, the air duct has the advantages that the production cost is reduced, and the production efficiency is improved. The overall service life of the air pipe is prolonged by more than three years, and the safety and economical efficiency of the air pipe in automobile application are improved.

    一种车用PET型材风管及其制造方法,所属汽车内饰技术领域,风管包括PP材质出风口、PET材质管体和HDPE材质接口;管体的进风端口连接接口,管体的出风端口连接出风口。本发明通过热压成型及焊接工艺的开发,生产出厚度为10~14mm,密度为400±10g/cm2的PET型材,实现了使用PET材料代替传统风管中使用的PP材料,从而有效的提高了整体风管的装配适用性、耐老化性及耐燃烧性,与现有同样规格的风管相比,本发明风管整体寿命延长三年以上,提高了风管在汽车应用中的安全性及经济性。
