For the entire automobile industry, the production of parts has become the most important industry. The steering wheel of a car is an important part of the car during use. In the previous steering wheel production process, the skeleton needs to be placed in the mold and injected with real-time reactive foamed plastic material for foaming and shaping. After shaping, the remaining material on the periphery of the steering wheel is mostly removed manually. During the manual cleaning of the remaining material, the steering wheel skeleton needs to be manually pressed in turn, and then the material is cut by the cutter. Each time a new steering wheel is cut, it needs to be manually held. This process is time-consuming and labor-intensive, resulting in a low efficiency in cleaning the remaining material.
