It is available in two material options: zinc alloy (Zamak 5, for heavy-duty load-bearing) and aluminum alloy (6063, for lightweight needs). The shell undergoes Die Casting and CNC finishing, resulting in a smooth surface (Ra ≤ 1.6μm) and tight dimensional tolerances (±0.1mm).
Produced by XinShang Metal—with 8+ years of zinc/aluminum alloy manufacturing experience—this bottom shell benefits from our rigorous quality control. Our 10 quality inspectors conduct 3-stage inspections (raw material, in-production, final) to ensure no defects like cracks or burrs. Our factory’s monthly production capacity reaches 50,000 units, meeting large-scale order demands.
Zinc alloy bottom shells have a tensile strength of 280 MPa and a compressive strength of 350 MPa, suitable for equipment weighing 50–100kg (e.g., automotive charging modules). Aluminum alloy versions, while lighter (density: 2.7 g/cm³), still support loads up to 30kg, ideal for electronic devices like routers.
A electrophoretic painting or powder coating is applied to the shell’s surface, providing corrosion resistance (salt spray test: 500 hours without rust) and impact resistance (passes 1.5m drop test with no deformation). This ensures durability in humid or industrial environments.
Precision CNC-machined mounting holes and snap-fit structures reduce installation time by 40% compared to non-precision shells. The shell is compatible with standard screws (M3–M8) and can be directly assembled with other components (e.g., circuit boards, casings) without additional modification.
Serves as the bottom casing for servers, LED drivers, and communication routers, protecting internal circuits from dust, pressure, and accidental impacts. It also provides heat conduction paths to auxiliary heat dissipation.
Used as the bottom shell for EV battery brackets and engine sensors, withstanding high temperatures (up to 150°C) and vibration (10–200Hz) in engine bays, ensuring component stability.
Applied in portable medical monitors (e.g., blood glucose meters, ECG machines) for its lightweight, easy-to-clean surface, and resistance to medical disinfectants (e.g., ethanol, hydrogen peroxide).
Zinc alloy shells offer higher strength and vibration resistance, suitable for heavy-duty equipment. Aluminum alloy shells are 30% lighter and more cost-effective, ideal for weight-sensitive devices. Both meet IP54 dust and water resistance standards.
Yes. We offer custom color coatings (e.g., black, gray, white, or brand-specific hues) using eco-friendly paints. The minimum order quantity (MOQ) for custom colors is 500 units, with no extra cost for standard RAL color options.
Absolutely. We offer free samples (1–3 units) for quality and fit testing. Sample delivery takes 3–5 working days for standard models; custom samples (e.g., modified dimensions) take 7–10 working days, with the sample cost refundable upon bulk order placement.
