Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of automobile interior decoration, and in particular relates to a PET profile air duct for automobiles and a manufacturing method thereof. Background technique [0002] In the design and manufacturing process of passenger cars, traditional air ducts are used to transmit the hot and cold air produced by the car air conditioner to the air outlets of the driver's seat and the passenger's seat. Air ducts are a necessary part of the car. Both have applications. [0003] The traditional air duct structure is composed of air outlet, pipe body and interface, and its components are all made of PP or HDPE materials. This material has poor performance in aging resistance and combustion resistance, and the formed components have high hardness. The air duct cannot be adjusted during the assembly process, the adaptability is poor, and the installation mismatch problem often occurs. Contents of the invention [0004] A...
