SanJun Hardware is a professional one-stop sheet metal OEM manufacturer specializing in precision server housings, multi-function electrical boxes, industrial control cabinets and smart device enclosures.
Many clients struggle with lacking engineering drawings, high outsourced design fees and unoptimized structures causing production delays & high costs. Our veteran sheet metal engineering team solves all these troubles: we provide 100% free customized structural drawings, full DFM manufacturability analysis and multi-round design revisions purely based on your mounting size, assembly functions, application scenarios and performance demands. No drawing preparation required on your side. We cover the full workflow from concept sketch, dimension drawing, structural verification to final production drawing, cutting your R&D cycle, design outsourcing expense and trial-and-error risks significantly.
We own complete laser cutting, CNC bending, robotic welding & surface treatment equipment, deliver tight tolerance precision fabrication, support prototype & mass production with flexible MOQ, serving data center, industrial automation, intelligent control and communication equipment industries globally.
✅ Free Full Drawing Design Service, No Drawings Needed From You
You only need to inform us your product installation dimensions, assembly logic, working scenarios and performance standards. Our senior engineering team independently completes sketch drafting, detailed dimension layout, structural rationality inspection and formal production drawing output at zero cost. Multiple rounds of drawing optimization & revision are supported until fully matching your assembly requirements. No extra design outsourcing fees, no self-drawing workload for your R&D team.
✅ Professional DFM Manufacturability Optimization
We conduct full DFM analysis at the design stage, revise unreasonable structures that lead to difficult processing, deformation or high costs, optimize material usage and assembly layout in advance, avoid post-sampling rework and greatly reduce your trial risk & overall production cost.
✅ Full In-House Precision Sheet Metal Fabrication
Full production processes under one roof: laser cutting, CNC bending, precision stamping, robotic MIG/TIG welding, tapping, hardware insertion, polishing, powder coating, anodizing, plating and complete assembly. Tight tolerance ±0.1mm, solid structural reinforcement, good heat dissipation & EMI shielding performance for server chassis.
✅ Flexible Production & Fast Lead Time
Support 1-piece prototype & large batch mass production without high MOQ pressure. 24H DFM review & quotation, sampling within 7 working days, mass production finished in 10–15 days based on quantity.
✅ All-Round Customization Support
Custom size, material (SPCC, SGCC, aluminum, stainless steel), ventilation hole layout, mounting brackets, lock structure, surface color, logo printing and IP protection grade to fit data center, industrial workshop, outdoor intelligent equipment and control room use.
