Why Choose XML Tech?
In custom metal sheet enclosure manufacturing, we understand that functionality and aesthetics are equally critical. Whether you are dealing with high-density electronic packaging inside a compact sheet metal enclosure box, specific EMI/RFI shielding for a complex Electrical Panel, or extreme outdoor environments that demand a rugged waterproof sheet metal enclosure, XML Tech leverages comprehensive capabilities to overcome your toughest challenges. From large sheet metal enclosures like a heavy-duty Power Distribution Cabinet to a precision Sheet Metal Bracket, we deliver:
- Handling Complex Structures: We excel in multi-component precision assembly, seamless welding, and intricate internal bending. Through upfront DFM (Design for Manufacturability) reviews, we resolve interference issues to ensure perfect integration of internal PCBs, cooling modules, and hardware components.
- Versatility in Special Materials: From copper/brass requiring strict thermal and electrical conductivity, to 316L stainless steel demanding extreme corrosion resistance, or lightweight aerospace-grade aluminum alloys, we have a mature processing methodology for every material.
- Flawless Surface Finishes: For medical devices, high-end servers, and consumer electronics, we deliver zero-defect surface treatments. We strictly control scratching during fabrication to achieve uniform powder coating, refined brushing, and flawless anodizing, meeting the highest cosmetic inspection standards.

Frequently Asked Questions
We offer highly flexible manufacturing solutions. At XML Tech, there is no strict MOQ. We fully support low-volume prototyping (even starting from 1 piece) for your engineering verification, and can seamlessly scale up to high-volume mass production runs of thousands of units.
To ensure the highest accuracy, we prefer 3D CAD models in STEP (.stp) or IGES (.igs) formats. We also accept SolidWorks (.sldprt) files. Additionally, please provide 2D drawings in PDF or DWG/DXF formats to specify hardware insertions, critical tolerances, and surface finish requirements.
As an ISO-certified, all-around hardware manufacturer, quality is built into our process. We start with a comprehensive DFM (Design for Manufacturability) analysis. During production, we conduct rigorous first-article inspections, in-process routing checks, and utilize advanced CMM equipment to ensure all tight tolerances and flawless cosmetic finishes meet
Lead times depend on the complexity of the enclosure and surface finishes. Typically, rapid prototypes can be delivered in 3 to 7 business days. For scalable mass production, our standard lead time is generally 2 to 4 weeks. We will provide an exact timeline alongside your quotation.
