Metal Chassis Techspecs

Our metal chassis are engineered to precise specifications. Materials include stainless steel SUS304 and SUS316, aluminum 5052 and 6061, carbon steel, galvanized steel, copper, and brass. Thickness ranges from 0.5mm to 6.0mm for electronics applications and up to 20mm for heavy-duty industrial chassis. Dimensional tolerances are held to plus or minus 0.05mm for critical features, with stamping and bending accuracy ensured by real-time laser angle compensation. Surface finishing options include powder coating with any RAL color, anodizing, electroplating, polishing, and painting. Custom features include mounting holes, connector cutouts, ventilation louvers, and internal partitions. Every batch is backed by Mill Test Certificates ensuring full material traceability.

Custom Metal Chassis Parts

Lingyufab specializes in producing custom metal chassis parts including electronic chassis with PCB mounting provisions, server chassis with rack-mount rails, industrial chassis for PLC enclosures, medical chassis with cleanroom-compatible finishes, automotive chassis for sensor modules and ECUs, and sub-panels and internal brackets. Each part is tailored to your assembly requirements, with provisions for EMI shielding, thermal management, and cable routing. Our engineering team provides upfront technical support, including design optimization, K-factor verification, and cost-reduction recommendations. We support reverse engineering services. If you have a physical sample without drawings, we can 3D scan, model, and generate production-ready engineering prints. Whether you need a single prototype or thousands of units, we deliver consistent quality with zero MOQ for prototyping stages.

Metal Chassis Applied in Sheet Metal Fabrication

What truly sets Lingyufab apart is our ability to integrate the full spectrum of sheet metal processes, including laser cutting, CNC bending, stamping, welding, assembly, and surface treatment, into a seamless manufacturing workflow for metal chassis. Rather than outsourcing individual steps to multiple vendors, we manage everything in-house, ensuring tighter quality control, faster lead times, and consistent communication throughout the entire production cycle. With our in-house fastener manufacturing, we can pre-install self-clinching studs, PEM nuts, SEMS fasteners, bolts, and nuts directly into your chassis, eliminating external fastener sourcing and reducing assembly time on your end. The result is a streamlined, cost-effective solution that performs reliably in the field.

What is Metal Chassis?

A metal chassis is a structural framework fabricated from metal sheets through processes including laser cutting, stamping, CNC bending, and welding. It provides the foundational support and protection for electronic components, PCBs, and mechanical systems in various applications ranging from desktop electronics to heavy industrial equipment. At Lingyufab, we manufacture chassis strictly to customer 2D prints in PDF, DWG, and DXF formats and 3D CAD models in STEP, IGES, and SolidWorks formats, ensuring 100 percent build-to-print execution.

Features of Metal Chassis

1. High structural strength with optimized geometry and stamped reinforcements

2. Excellent EMI shielding for sensitive electronic components

3. Customizable sizes, shapes, and mounting provisions including PCB standoffs and PEM nuts

4. Compatible with multiple surface treatments for corrosion resistance including powder coating, anodizing, electroplating, and painting

5. Can incorporate ventilation louvers, connector cutouts, cable ports, and internal partitions

6. Integrated fastener solutions with self-clinching studs, PEM nuts, and SEMS fasteners pre-installed in-house

Applications of Metal Chassis

These chassis are deployed in electronics for server enclosures and computer cases, telecommunications for base station chassis and rack-mount frames, industrial automation for PLC housings and control panels, medical devices for diagnostic equipment chassis and surgical trays, and transportation for vehicle electronic housings and sensor mounts. They provide structural support and protection for sensitive components in demanding conditions. Lingyufab serves OEM clients across electronics, telecommunications, industrial equipment, medical, and automotive sectors.

Metal Chassis Guide for Sheet Metal Assembly

When integrating a metal chassis into an assembly, consider PCB mounting orientation, connector alignment, thermal dissipation, and cable routing. Ensure proper grounding and EMI shielding to meet regulatory compliance. Recommended design practices include maintaining minimum flange length of at least 4 times material thickness, using consistent bend radii to reduce tooling changes, and adding bend relief notches at corners to prevent tearing. Our engineering team provides assembly drawings, PCB mounting guidelines, and installation recommendations to streamline your final integration.
