Why India for fab & machining: mature clusters with laser/water-jet cutting, robotic welding, multi-axis CNC, and in-house finishing—backed by India’s US$109.3 bn engineering-goods exports in FY 2023–24 (scale you can bank on).

What we build

• Sheet metal: laser/punch, bends, roll-form, spot/MIG/TIG, clinch/rivet; CED/powder-coat/painted.
  
• CNC machining: 3–5-axis milling & turning, jigs/fixtures, GD&T-driven inspection.
  
• Welded assemblies: carbon/alloy/stainless; WPS/PQR, weld-maps, distortion control; robot cells where volumes suit.
  
• Surface treatments: Zn/Zn-Ni electroplating, hot-dip galvanizing, anodizing, phosphating, e-coat, powder/LIQ paints to duty class.
  

The standards we embed (buyers care about these)

• Welding system & workmanship: ISO 3834 (welding quality requirements) with welder/procedure quals; ISO 5817 weld quality levels B/C/D for acceptance.
  
• Dimensional framework: ISO 2768-1 general tolerances (f/m/c/v), ISO 1101 for GD&T on drawings.
  
• Corrosion & coatings:
  
  • Salt-spray: ISO 9227 (NSS/AASS/CASS) or ASTM B117 equivalents per spec.
    
  • Paint systems & durability: ISO 12944-5 selection by environment (C2–CX/Im classes).
    
  • Electroplating: ISO 2081:2018 (zinc) and ISO 19598 (zinc-alloy Zn-Ni/Zn-Fe, Cr(VI)-free).
    
  • Hot-dip galvanizing: ISO 1461:2022.
    
  • Adhesion & thickness checks: ISO 2409 cross-cut; ISO 2178 (magnetic) / ISO 2360 (eddy-current) for coating thickness.
    
  • Surface prep before paint: ISO 8501-1 visual cleanliness grades (Sa/St).
    

How IndiaUnbox delivers (spec-tight, audit-ready)

• DFM for cost & quality: nesting, bend reliefs, datum scheme, weld sequence, fixture strategy; material swaps (e.g., CR to HR-pickled where viable).
  
• Process plans & qualifications: WPS/PQR, welder quals; weld-map with CTQs; coating stack defined by environment target (e.g., C3/C4 per ISO 12944).
  
• Inspection you can trust:
  
  • Dimensional: control plans with Cp/Cpk targets, MSA (GR&R), CMM checks aligned to the ISO 10360 acceptance framework.
    
  • Weld/NDT: VT/MT/PT/UT/RT by ISO 9712-certified personnel; acceptance to ISO 5817
    
  • Finish: salt-spray to ISO 9227 hours set by spec; adhesion (ISO 2409), film-build via ISO 2178/2360.
    
• Materials & traceability: IS/ASTM grades (e.g., IS 2062 structural, IS 513 CR sheet) logged with MTCs; heat/lot trace to assemblies.
  
• Packaging & logistics: corrosion-inhibitor wraps, desiccants, edge guards; export-grade cartons/crates; consolidated CBM planning.
  

Typical acceptance pack (you receive this with every lot)

• Docs: drawings Rev#, spec matrix, ISO 3834 scope, WPS/PQR copies, coating SOP, PPAP/FAI where required.
  
• Inspection: full dimensional report (GD&T), weld visual & NDT logs, CMM file, hardness/micro where applicable.
  
• Finish tests: salt-spray/photos at intervals, ISO 2409 adhesion class, film-build data (ISO 2178/2360).
  

Example scope (illustrative)

• Sheet-metal: control panels, enclosures, brackets, guards, frames, battery trays, HVAC ducts, kiosks.
  
• CNC: bases, manifolds, spindles, hubs, precision spacers, shafts, housings.
  
• Weldments: skids, carts, machine frames, guard rails, forklift/AGV attachments.
  
• Finishes: Zn / Zn-Ni + sealer, e-coat + powder top-coat, duplex (galv + paint) to target ISO 12944 class.
  

KPIs we commit to

• First-time PPAP/FAI pass, ppm targets agreed upfront.
  
• Dimensional capability on CTQs (typ. Cpk ≥ 1.33; 1.67 where safety-critical).
  
• Corrosion performance matched to spec (e.g., NSS ≥ 240/480/720 h depending on coating system).
  

Bottom line: IndiaUnbox turns India’s fabrication depth into spec-tight, standards-compliant parts—from ISO 3834 welding and ISO 5817 acceptance to ISO 12944 paint design and ISO 9227 performance—so your buy lands on-brand, on-time, on-cost with paperwork your QA team will love.
