Door, interface layout, and high strength and lightness of internal support structure. It meets the requirements of printing equipment for precision (hole position, dimensional tolerance up to ±0.05mm), protection (IP30 - IP54 dust and water resistance), and electromagnetic shielding (integrated shielding cover), providing a reliable hardware foundation for the integration of printing, copying, scanning and other functions. It is widely used in office printing scenarios and helps the miniaturization and modular design of equipment.

　　Features

　　1. High-precision adaptability

　　Relying on CNC equipment and customized molds, the complex structure of the printing equipment can be accurately stamped. For example, the hole position tolerance of the guide bracket of the paper feed unit is controlled within ±0.03mm to ensure the smooth operation of the paper pickup wheel and transmission components; the bending angle error of the paper outlet is ≤1° to avoid the risk of paper jam and ensure long-term stable printing of the equipment.

　　2. Multi-material compatibility optimization

　　Cold-rolled steel: used for the main frame of the equipment, after stamping + spraying, it has high strength, low cost, strong anti-deformation ability, and is adapted to the load-bearing requirements of the printer body.

　　Aluminum alloy: used for internal heat sinks and lightweight trays. After stamping, it is anodized. It has fast heat conduction and light weight, which helps miniaturize the equipment. For example, the aluminum alloy shell of a portable all-in-one machine can reduce weight by more than 30%.

　　Stainless steel: used for easily worn parts such as the paper feed roller bracket. After stamping, the wear resistance is improved and the service life is extended by 2-3 times, which is suitable for high-load printing scenarios.

　　3. Functional integrated design

　　One stamping integrates multiple functions:

　　The heat dissipation shutter (opening rate 25%) of the shell replaces the additional heat dissipation module and reduces the power consumption of the equipment;

　　Built-in electromagnetic shielding ribs (stamped synchronously with the shell) reduce printing signal interference and improve the accuracy of graphic output;

　　Snap-on installation structure simplifies the assembly of internal circuit boards and ink cartridge components, and improves production efficiency by 40%.

　　4. Strict protection performance

　　 Dustproof and waterproof: Through the bending sealing process + rubber strip, the device shell protection level reaches IP42 (office scene) or IP54 (industrial scene), resisting the intrusion of dust and splashing liquid;

　　 Weather-resistant and wear-resistant: The surface is powder-coated (coating thickness 80-120μm) or electroplated, and the salt spray test exceeds 800 hours, which is suitable for long-term use in office environment, and the risk of shell scratches and corrosion is reduced by 60%.

　　Product details

　　Precision sheet metal stamping for multifunctional printing equipment runs through the entire process from equipment development to mass production, providing core structural parts for all-in-one printers, digital multifunction machines, etc.

　　Production process

　　1. Design collaboration: Deeply connect with equipment development, design sheet metal structures (including paper feed channel, ink cartridge bin, control panel bracket) based on printing functions (such as double-sided printing, wireless scanning), use simulation software to simulate stamping stress, optimize bending radius, opening layout, and reduce later debugging costs.

　　2. Precision processing: Select 1.0 - 2.5mm metal sheets, cut by laser (edge burrs ≤ 0.02mm), complete punching (such as USB interface, heat dissipation holes), forming (such as arc-shaped paper output bin) by CNC punching machine, and realize multi-station bending (angle accuracy ±0.5°) by bending machine to ensure perfect adaptation of structure and equipment electrical layout.

　　3. Surface treatment: After deburring and passivation, stamping parts are sprayed (customized RAL color number to match the office environment), electroplated (nickel plating of stainless steel parts to prevent fingerprints), and anodized (aluminum alloy parts to improve hardness) as needed to enhance protection and aesthetics.

　　4. Quality inspection and delivery: Dimensional accuracy is tested by three-coordinate measuring instrument, structural strength is tested by simulating equipment operation vibration, and dustproof, waterproof and weather resistance are verified by sampling to ensure that each batch of products meets the GB/T 15055 sheet metal processing standard and the equipment yield rate exceeds 99% after installation.

　　Application scenarios and value

　　1. Office printing: Create a compact sheet metal shell for the A4 all-in-one machine, integrate the scanning platform, paper box, and paper output tray to achieve miniaturization of the equipment and adapt to the space of offices and printing shops; through electromagnetic shielding design, it ensures that the printed documents are clear and interference-free, and improves the quality of printing.

　　2. Industrial printing: stamping high-strength stainless steel frames for large-format blueprint printers to withstand workshop dust and vibration, optimizing wear-resistant treatment of sheet metal parts of paper feed units, supporting 24-hour continuous printing, and facilitating efficient output of engineering drawings and production labels.

　　3. Smart terminals: customizing special-shaped sheet metal shells (such as curved operation panel brackets) for self-service printing terminals, stamping integrated cameras, card swiping areas, and QR code scanning ports to meet the needs of unmanned printing scenarios and enhance the interactive experience of the device.
