SMC Car Door Frame Corrosion Resistant Vehicle Door Frame Black For New Energy

Product Specification

SMC New Energy Vehicle Door Panel Frame Product Introduction

Our company’s core product is the SMC composite door panel frame. Leveraging the superior physical and chemical properties of SMC (special glass fiber-reinforced resin composite material) and manufactured using an integrated compression molding process, it serves as a lightweight core structural component for the interiors of passenger cars, commercial vehicles, and new energy vehicles. It completely resolves the  points associated with traditional metal and plastic door panel frames and offers significant overall performance advantages.

I. Stable Material Properties, Suitable for Complex Driving Scenarios

The product uses high-quality SMC molding compound as its core raw material, offering exceptional temperature stability. It can be used long-term in extreme temperatures ranging from -40°C to 120°C, withstanding intense heat from sunlight inside the vehicle and freezing damage in winter without warping, deforming, or cracking. At the same time, the material offers excellent corrosion and aging resistance, effectively withstanding in-cabin humidity and minor oil contamination, which significantly extends the product’s service life and meets vehicle usage requirements across various road conditions and climatic environments.

II. Lightweight Design to Enhance Vehicle Fuel Efficiency and Reduce Energy Consumption

Compared to traditional steel door panel frames, SMC composite materials have a lower density, enabling the finished product to achieve a weight reduction of 35%–45%, effectively lowering the vehicle’s curb weight. This lightweight structural design reduces energy consumption during driving, improving fuel economy for gasoline-powered vehicles and extending the driving range of new energy vehicles, all without compromising structural strength—thus achieving a balance between weight reduction and structural integrity.

III. One-Piece Molding for Enhanced Structural Integrity and Compatibility

The product is manufactured using a high-temperature, high-pressure one-piece compression molding process, which allows for the simultaneous formation of structural elements such as reinforcing ribs, speaker mounting holes, latch positioning pins, and armrest mounting bases—eliminating the need for secondary welding or assembly. The resulting structure features high integrity and precision, with excellent fit and alignment during assembly. This effectively prevents issues such as rattling or loosening of door panels during vehicle operation, while also meeting the requirements for interior modifications and mass-production assembly across multiple vehicle models.

IV. Noise and Vibration Reduction, Enhancing the Driving Experience

SMC composite materials inherently possess damping and vibration-absorbing properties. Compared to ordinary plastics and metals, they effectively absorb and attenuate resonance noise and vibrations generated by the car doors during driving, optimizing the vehicle’s NVH performance and reducing in-cabin noise interference to provide users with a quieter and more comfortable driving environment.
