Dongfeng VL truck part Right door sill pressure strip assembly 5102010-C0150

Built to withstand frequent foot traffic (a common wear point for truck sills), the pressure strip uses a dual-material construction: the top surface is made of high-density thermoplastic elastomer (TPE) with a Shore A hardness of 75±5, offering flexibility to resist cracking from impacts (e.g., boots stepping on edges) while maintaining shape. The bottom support layer is rigid ABS plastic (1.5mm thick) with a tensile strength of 45 MPa, providing structural stability to prevent bending under pressure. The TPE surface is treated with an anti-scratch coating (pencil hardness ≥2H) that resists scuffs from work boots or tools, retaining its appearance even after 10,000+ contact cycles. Unlike rubber strips that harden over time, this TPE-ABS composite ensures long-term durability, matching the VL’s cab service life

Engineered to block dust, rainwater, and road debris from entering the cab through the door sill gap, the assembly features a multi-layer sealing structure. A 3mm-tall TPE lip seal runs along the strip’s top edge, pressing tightly against the door’s lower edge when closed to form a water-tight barrier (tested to resist 500mm/h rain without leakage). The bottom edge has a self-adhesive foam tape (1.5mm thick, acrylic-based) that adheres to the cab floor, sealing gaps between the strip and sill to prevent dust accumulation. Additionally, the strip’s end caps (made of ABS) are ultrasonic-welded to the main body, eliminating end gaps that could let debris in. This sealing design reduces cab interior cleaning frequency by 40% and protects the cab floor from water damage (e.g., rust on metal floors)

Prioritizing driver and crew safety during entry/exit (especially in wet conditions), the TPE top surface features a raised diamond texture (0.8mm height) with a coefficient of friction (COF) of ≥0.6 when wet—30% higher than smooth surfaces. This texture provides secure foot grip even when boots are muddy or wet, reducing the risk of slips. The texture also traps minor debris (e.g., sand) to prevent it from being tracked into the cab interior. Unlike smooth pressure strips that become slippery in wet weather, this anti-slip design ensures safe access to the cab in all working conditions, critical for Dongfeng VL’s heavy-duty applications (e.g., construction, mining) where crews often work in harsh environments

Designed for quick, hassle-free replacement (no professional tools needed), the assembly uses a dual-fixation system: pre-installed plastic clips (matching the VL’s cab floor clip holes) for mechanical positioning, and high-strength acrylic foam tape (3M VHB equivalent) for permanent adhesion. Installation takes 15–20 minutes: clean the right door sill with isopropyl alcohol to remove grease/dust, align the strip’s clips with the cab floor holes, press firmly to engage the clips and activate the adhesive, then apply pressure along the entire length to ensure full bonding. No drilling or modification to the cab floor is required, preserving the original structure. Each unit undergoes adhesion testing (15N/cm² bond strength), dimensional checks, and anti-slip performance verification, backed by a 12-month warranty against defects (e.g., TPE peeling, adhesive failure, end cap detachment)
