Precision sheet metal stamping for vertical intelligent device housings is a technology that uses CNC punching, laser cutting, bending and other processes to accurately process cold-rolled steel, aluminum alloy, stainless steel and other metal sheets (usually ≤6mm) for vertical intelligent terminal housings (such as access control machines, inquiry machines, self-service terminals, etc.). Through blanking, punching, bending, forming, surface treatment and other processes, the highly adaptable structure of the device housing (fitting the internal electrical component layout) and complex appearance (such as curved surfaces and special-shaped splicing) are achieved, and the dimensional accuracy (tolerance within ±0.1mm) and protection performance (IP30 - IP65 dust and water resistance) are guaranteed, providing electromagnetic shielding, physical protection and beautiful appearance for the equipment. It is widely used in scenarios such as smart offices, smart communities, and commercial services, and helps the miniaturization and integration of smart device hardware.

Highly adaptable structural design | According to the layout of the internal motherboard, display screen, and interactive module of the device, the installation holes, wiring grooves, and heat dissipation channels are accurately stamped, with a hole tolerance of ±0.05mm, to ensure seamless assembly of electrical components, avoid interference, and improve equipment integration efficiency. |
Multi-material performance optimization | - Cold-rolled steel: low cost, high strength, stamping + spraying, suitable for cost-sensitive general-purpose smart terminals; |
Complex appearance molding | - Aluminum alloy: lightweight, excellent thermal conductivity, exquisite appearance after anodizing, suitable for high-end self-service equipment; |
Strict protection and shielding | - Stainless steel: corrosion-resistant, wear-resistant, suitable for outdoor, medical and other high-clean scenes after stamping. |
Product Details
Precision sheet metal stamping of vertical smart device shells is the core link of smart terminal hardware manufacturing, covering the entire process from prototype proofing to mass production.
Production process:
1. Design collaboration: Deeply connect device functions (such as face recognition, card swiping interaction) with appearance requirements, use CAD to design shell structure, simulate stamping stress and assembly compatibility, optimize bending radius and splicing methods, and reduce post-debugging.
2. Precision processing: Select 0.8-3mm metal sheets, cut by laser (edge burrs ≤ 0.02mm), complete punching (such as power interface, heat dissipation holes), forming (such as curved operation panel) by CNC punching machine, and multi-station bending by bending machine (angle accuracy ±0.5°) to ensure perfect fit with internal components.
3. Surface treatment: After deburring and passivation, stamping parts are sprayed as needed (customized RAL color number, matching scene style), electroplated (anti-fingerprint for stainless steel parts), and anodized (enhanced hardness and texture for aluminum alloy parts) to enhance protection and beauty.
4. Quality inspection and delivery: Use three-coordinate measuring instrument to detect dimensional accuracy, simulate the equipment use environment (vibration, humidity) to test structural strength, sample to verify protection level and electromagnetic shielding performance, ensure compliance with GB/T 13912 metal covering layer standard, and the installed yield rate exceeds 98%.
Application value:
Smart community: stamping cold-rolled steel + spray-painted shell for access control integrated machine, integrated camera hole, card swiping area, display slot, protection level IP54, resistant to outdoor temperature difference and dust, to ensure stable operation of access control system.
Commercial service: create an aluminum alloy anodized shell for self-service inquiry machine, arc bending + minimalist opening design, taking into account both beauty and heat dissipation, and improving user interaction experience in shopping malls, banks and other scenes.
Industrial scenario: Customized stainless steel stamping shell for workshop smart terminals, which is corrosion-resistant and easy to clean, adapts to industrial-grade data collection and equipment control requirements, and ensures the life of equipment in complex environments.
