Dongfeng VL truck parts Left emblem decorative strip assembly 5000519-C4310

The decorative strip’s base is crafted from high-impact ABS plastic (acrylonitrile butadiene styrene) reinforced with 12% glass fiber, delivering a flexural modulus of 2,750 MPa to resist bending or cracking from minor impacts (e.g., road gravel). Its surface undergoes a triple-layer chrome plating process: a 5μm copper undercoat for adhesion, a 3μm nickel layer for corrosion resistance, and a 2μm chrome topcoat for a mirror-like finish. The chrome layer achieves a gloss rating of 92% (measured via 60° gloss meter), matching the VL’s factory chrome accents (e.g., left-side door handle trim). Unlike low-quality electroplated strips, it resists scratch damage (pencil hardness: H) and retains shine even after 2,200 hours of UV exposure testing (equivalent to 3 years of outdoor use)

Engineered to withstand harsh outdoor conditions, the assembly integrates a dual-protection coating system. A 15μm-thick polyurethane clear coat is applied over the chrome layer, blocking 99% of UVA/UVB rays to prevent chrome peeling or discoloration in direct sunlight. The ABS base is infused with anti-aging additives, enabling it to operate in temperatures ranging from -40°C (arctic winters) to 85°C (desert heat) without brittleness or warping. It also resists chemical damage: testing confirms no blistering or fading after 500 hours of exposure to 5% salt spray (road salt) and 200 hours of contact with diesel fuel. This weather resistance ensures the strip remains visually intact even after long-term use in extreme climates

The assembly features a molded-in Dongfeng brand emblem (118mm×29mm) positioned centrally on the left-side strip, using a 3D raised design (0.45mm height difference from the strip surface) to create visual depth and tactile recognition. The emblem’s color scheme—Dongfeng’s signature red (Pantone 186 C) and silver (Pantone 877 C)—is applied via a high-temperature baking process (185°C curing) that bonds the pigment to the ABS base, preventing fading or chipping. Unlike stick-on emblems that risk detachment from vibration, the integrated design ensures the logo remains secure even after 1,500 hours of 200Hz vibration testing (equivalent to 100,000 km of road use). This reinforces brand visibility while maintaining a premium, factory-fitted look

The strip supports two hassle-free installation methods to match the VL’s factory setup:

Bolt-Mount: Includes 4 stainless steel M4×10mm bolts (grade 304) and lock washers, fitting the truck’s pre-drilled left-side mounting holes. Torque specification (8 N·m) aligns with OEM standards to avoid over-tightening damage to the cab panel.

Adhesive-Mount: Features pre-applied 3M VHB acrylic foam adhesive (1.5mm thick) on the strip’s back, offering a bond strength of 14.5 N/cm² that resists detachment from temperature changes or vibration.

Installation takes 15–20 minutes: clean the left-side mounting surface with isopropyl alcohol, align the strip using OEM reference marks, either bolt it in place or press firmly for adhesive bonding, and allow 24 hours for adhesive curing. No drilling or modification to the truck’s body is needed. Each unit undergoes dimensional checks (via CMM), adhesion testing, and finish inspections, backed by a 12-month warranty against defects (e.g., chrome flaking, adhesive failure, emblem fading)
