Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, in particular to a multifunctional flame treatment tire turning device. Background Art

[0002] The manufacturing process for soft automotive instrument panels primarily involves polyurethane foaming (filling the space between the instrument panel and the slush-molded surface with polyurethane foam), blister molding (spraying glue on the skeleton and then laminating it with the blister), and overmolding (overmolding the skeleton, 3D mesh, and skin after spraying glue). Overmolded products are highly sought after by consumers for their soft, comfortable feel, premium texture, and more complex and varied shapes, and currently represent an increasing share of soft instrument panels. Soft instrument panel skeletons are primarily made of non-polar materials such as PP+EPDM-T20 or PP+GF30. Flame treatment is required to increase the surface dyne value for optimal adhesion to adhesives and meet automotive regulatory testing requirements, such as static airbag deployment. Due to the complex shape of overmolded products and the need for reverse wrapping in many locations, flame treatment tooling is required for production, including instrument panel flipping and flame shielding. Existing flame treatment tooling, however, is simple in structure and does not meet practical requirements. Utility Model Content
