At present, the pipeline materials used in automobiles can be divided into three categories, which are nylon pipes, rubber pipes and metal pipes. Commonly used nylon tubes are mainly PA6, PA11 and PA12, these three materials are collectively referred to as aliphatic PA, PA6, PA12 for ring-opening polymerization, PA11 for condensation polymerization. In general, the simpler the molecular material of the automotive pipeline, the easier it is to crystallize
The processing procedure of nylon tube is:
▼ Extrusion process: Raw material supplier provides raw material particles to pipeline supplier. The pipeline supplier must first make the particles into pipelines, and the production equipment is mainly composed of several sections
▼ Forming process: Shape the extruded straight pipe into the required shape.
▼ Assembly process: According to the design requirements, the joint is connected with the pipeline. There are generally the following types of connection: ① slub type ② clamp type
