Distributed solar installations, commercial microgrids, and electric mobility hubs across Africa require robust, weatherproof sheet metal housings. Off-the-shelf plastic utility boxes frequently crack under sustained solar UV exposure or fail to support heavy iron-phosphate (LiFePO4) battery packs. FamilyMake is rolling out its private beta program for precision sheet metal fabrication to solve this manufacturing gap.
Core Sheet Metal Capabilities
Our hybrid production workflow pairs internal design review and finishing with high-power industrial fiber laser cutting and multi-axis CNC press brakes:
- Fiber Laser Cutting: High-speed optical cutting of mild steel up to 16 mm, stainless steel 304/316 up to 10 mm, and structural aluminium up to 8 mm, maintaining edge squareness and positional tolerances within ±0.1 mm.
- CNC Press Brake Bending: Multi-bend profiles with automated backgauging, ensuring precise bend angles and spring-back compensation across batch runs.
- PEM Fasteners and Clinch Hardware: Pre-pressed self-clinching threaded studs, standoff nuts, and blind rivets that eliminate the need for surface welding on clean electrical panels.
- Surface Finishing: High-durability thermoset powder coating (RAL color matching) offering over 1,000 hours of salt-spray corrosion resistance for outdoor substations.
Key Design Rules for Sheet Metal Enclosures
To keep costs low and eliminate bending collisions, hardware engineers should observe several fundamentals:
- Uniform Sheet Thickness: Keep all components in a welded chassis to a single sheet gauge (e.g., 1.5 mm or 2.0 mm) to avoid changing raw sheets during nesting runs.
- Bend Relief Grooves: Always add rectangular or teardrop relief notches at corners where bends meet edges to prevent tearing and material bulging.
- Minimum Hole-to-Bend Distance: Holes placed closer than 2.5 times sheet thickness from a bend line will deform into ovals during press brake forming.
