Safeguarding Auto Body Panels from Scratching During Logistics

Auto body panels like doors, hoods, and fenders are highly susceptible to cosmetic damage and denting during transit. Even minor scratches can lead to part rejection on the final assembly line, costing tier-1 suppliers thousands of dollars.

In this article, we outline key design features for custom automotive racks that prevent metal-on-metal friction and protect Class-A panel surfaces.

1. Specifying Custom Isolation Liners (Dunnage)

Using bare steel columns is a recipe for paint scratching. We specify custom protective barriers:

• High-Density Polyethylene (HDPE): Excellent wear resistance and structural slickness. Best for slide guides.
• Polyurethane (PU) Padding: Offers high cushioning factors. Recommended for high-vibration engine bay panels.
• EPDM Rubber Strips: Weather-proof and shock absorbing. Fitted along structural base profiles.

2. Nesting and Orientation Geometry

Racks must hold panels securely at precise pitch intervals:

• Comb-like dividers: Laser-cut steel sheets lined with rubber to isolate panels individually.
• Gravity-assist locking: Ensuring parts naturally slide into a secure locked nest under their own weight.

3. Vibration Dampening Features

Logistics trailers generate significant harmonic vibration on concrete highways. Racks must incorporate:

• Heavy-duty compression spring pins.
• Cushioning pads on stackable corner sleeves.
