Manufacturing process of automotive glass guide rail


  The main purpose of the automotive glass guide rail is to make the glass go up and down smoothly, slide the guide rail, absorb vibration and reduce vibration. The traditional automotive glass guide rail is stamped and formed from a thin plate and embedded with flocking rubber strips. However, due to structural and material reasons, the amount of deformation that can be adapted If the glass guide rail is small, there will be phenomena such as slower glass lift and abnormal noise, and the production cost may become higher. Then, let's learn about the manufacturing process of the automotive glass guide rail together!

Auto glass guide rail

  The purpose of the present invention is to directly injection mold polyoxymethylene POM material in a mold with corresponding structure in the manufacturing process of automobile glass guide rail, use polyoxymethylene POM material to directly injection mold the main body of automobile glass guide rail, and partially insert metal components to achieve the mechanical properties of glass rails for automobiles.

  Polyoxymethylene (POM) is a kind of engineering plastic with excellent comprehensive performance, which has good corrosion resistance, oil resistance, chemical resistance, Low water absorption, wear resistance and self-lubricating properties, creep resistance and outstanding fatigue resistance, is one of the resin varieties whose specific strength is closer to that of metal in all plastics. In this way, it can also meet the requirements in terms of function, and greatly reduce the cost. It can adapt to a large amount of deformation, and it is also easy to carry out firm and reliable assembly and maintenance of the glass guide rail assembly. The overall manufacturing process is simple and the cost is low.

  Specific implementation of automobile glass guide rail

  The manufacturing process of the automotive glass guide rail is characterized in that polyoxymethylene POM material is used for direct injection molding in the mold of the corresponding structure, and polyoxymethylene POM material can also be used for direct injection molding of the body, and the mechanical properties are partially improved through metal inlays.
