Description

Technical Field

[0001] The utility model relates to the technical field of automotive interior foam, and particularly relates to a rolling cutting and forming device for automotive interior foam. Background Technique

[0002] Automotive interior foam is a material used for automotive interior decoration, usually referring to polymer materials with a foam structure. It is mainly used in the manufacture of automotive interior parts, such as filling, buffering, and sound insulation in seats, door panels, instrument panels, ceilings, etc. The foam material can provide a comfortable riding experience and also play a role in shock absorption, heat insulation, and sound absorption. Automotive interior foam can be selected from different types according to different performance requirements and uses. Common ones include polyurethane (PU) foam, polyethylene (PE) foam, ethylene-vinyl acetate copolymer (EVA) foam, etc. These materials have good elasticity and flexibility, can resist mechanical pressure and deformation, and at the same time have good weather resistance and aging resistance, and can be used in the automotive interior environment for a long time.
