[0002] Car trim strips are decorative accessories installed on the exterior or interior of a car body, mainly used to enhance the vehicle's aesthetics and protect body parts. Car trim strip cutting devices are specialized equipment for precisely cutting various types of car trim strips, enabling efficient and accurate cutting operations.

[0003] In the existing production process of automotive trim strips, after casting and pressing, the resulting universal lettering has a gate. This gate needs to be cut off to remove the individual trim strip before subsequent processes such as gluing. Typically, workers need to hold the trim strip in place and cut it with scissors. However, during manual cutting, the trim strip is prone to movement and shifting, affecting the cutting result. Furthermore, manual cutting often results in uneven cuts, requiring a second cut to avoid affecting later use. Therefore, we provide an automotive trim strip cutting device. Utility Model Content
