[0002] Automotive weatherstrips are an important component of automobiles. Their function is to prevent water, dust, noise, etc. from entering the car, while also reducing energy loss inside the car. To achieve this effect, automotive weatherstrips must have a certain degree of elasticity and durability, and the metal framework is one of the key components to achieve these properties.

[0003] Metal scaffolds for automotive weatherstrip extrusion are typically made of stainless steel or high-strength light alloys, and their shape and size are customized to specific vehicle models and weatherstrip specifications. The manufacturing process of a metal scaffold typically involves cutting, bending, punching, and other processes, requiring high-precision fixtures and skilled personnel. During the weatherstrip extrusion process, the metal scaffold provides sufficient support and dimensional stability to ensure the elasticity and durability of the weatherstrip. At the same time, the metal scaffold can also increase the rigidity and compressive strength of the weatherstrip, thereby better protecting the car body and window panes.

[0004] In the current technology, the production of metal scaffolds uses single-production equipment, and in order to increase production efficiency, the entire production line needs to be improved, so the cost of changing the production line is relatively high.
