Understanding what makes sheet metal fabrication unique helps customers choose the right manufacturing path. Our sheet metal manufacture serve leverages the following inherent advantages of the technology:
Thin-gauge metal delivers structural rigidity while minimising part weight — critical for enclosures, cabinets, and structural frames.
CNC-driven processes maintain dimensional consistency across thousands of parts with tolerances as tight as ±0.05 mm.
Laser cutting, punching, and bending can realise complex geometries, cutouts, and flanges from a single flat blank.
Cold-rolled steel, stainless steel, aluminium, copper, and galvanised steel are all supported in our standard workflow.
From prototype runs of 1–10 pieces to high-volume production of 100,000+ parts per month — our capacity scales with your needs.
Powder coating, galvanising, anodising, passivation, and silk-screen printing enhance both aesthetics and corrosion resistance.
Vertically integrated production means no third-party delays. Standard lead time is 7–15 business days for most projects.
Tooling costs are lower than casting or forging. Volume discounts apply beyond 500-piece orders, improving your unit economics.
Jiafeng's factory supports a comprehensive range of forming, joining, and finishing operations. Our OEM/ODM team will select the optimal technique combination for your project.
