Why India for auto components: A deep vendor base across Pune–Chakan, Chennai–Sriperumbudur, Sanand, Hosur, Rajkot, Coimbatore & Kolhapur delivers scale in presswork, forgings, ferrous/non-ferrous castings, and polymer/rubber parts—with global standards baked in. India is now the world’s #2 casting producer (≈12–14 million tonnes/year), and auto-component exports reached US$21.2 billion in FY 2023–24 with a trade surplus.

What we source & build

• Stampings & welded BIW/Brackets: progressive/transfer press parts (≤1,200 t), roll-formed sections, spot/MIG/robotic cells, CED/powder-coat paint lines.
  
• Forgings (closed/open die): carbon/alloy/SS; 300–5,000 t hammers/presses; heat-treat (N, Q&T), shot-blast, CNC finish-machining. (India’s forging industry has ~3.85 million t installed capacity—ample headroom.)
  
• Castings: SG/grey iron, steel, and aluminium (gravity/HPDC) with core-shop, fettling, CNC, and leak-testing; simulation-led gating/risering. (India ranks #2 globally in foundry output.)
  
• Rubber & plastics: seals, bushings, NVH parts, air-ducts, reservoirs, fan shrouds, interior/under-hood plastics (IM, blow, extrusion), over-moulded inserts.
  

Standards & compliance we align to

• Quality systems: IATF 16949, ISO 9001; APQP/PPAP with Level-3 dossier by default.
  
• Material & product: casting tolerances ISO 8062-3, mechanical & hardness to ASTM/EN, forging die life & decarb control, stamping surface & weld integrity to OEM specs.
  
• Testing & NDT: UT/RT/MT/PT, hardness, microstructure, tensile/impact; dimensional CMM/laser; leak (air decay/helium) where required.
  
• Chemical & substance: IMDS submissions for ELV/REACH/RoHS conformity on polymers, paints, and platings.
  

What buyers get (measurable)

• Capability indices: Cp/Cpk ≥ 1.67 on CTQs; GR&R for gauges; weld PQR/WPS and macro-etch records.
  
• Durability & corrosion: stack-up for coatings (e.g., Zn/Zn-Ni + sealer) tied to ISO 9227 (NSS/AASS/CASS) hour targets; paint cross-hatch & MEK rubs.
  
• Metallurgy control: heat-treat charts, hardness maps, spectro/PMI for alloys; ferrite/pearlite/nodularity checks for irons.
  
• Polymers & rubber: resin CoAs, ash/MFI, glass-fiber %, shore hardness; VOC/odour where OEM policy applies.
  

IndiaUnbox delivery model (how we de-risk)

1. Spec capture & cost-down
   DFM/VA-VE on thickness, ribbing, radii, draft, gate/runner design; forging-to-near-net conversions; press/tool set-up sheets; coating stack rationalisation.
   
2. Right suppliers, right clusters
   Shortlists across forging/casting/stamping/polymer lines with press/hammer tonnage, foundry melt capacity, HPDC tonnage, and moulding machines mapped—plus past export lanes and audit scores. (Foundry depth validated by India’s #2 global rank; exports by ACMA Performance Review.)
   
3. Prototype → FAI → PPAP
   Sample control plan, dimensional & material reports, MSA/GR&R, PFMEA/CP, and Level-3 PPAP (PSW, IMDS ID, capability studies).
   
4. Process control & labs
   Heat-treat recipes (Q&T/normalise), porosity/oxide control in Al castings, helium/air-decay leak tests, CMM fixtures; accredited lab tie-ups for NDT & metallurgy.
   
5. Compliance & documentation
   IATF scope, IMDS IDs, REACH/SVHC, RoHS, country-of-origin, packaging ISPM-15 (where wood used); full photo log at pre-dispatch.
   
6. Logistics & continuity
   Dual-sourcing within cluster; buffer-stock & kanban options; sea/air multimodal plans with corrosion-inhibitor packaging where needed.
   

Typical scope (illustrative SKUs)

• Stampings: seat/bracketry, chassis gussets, pedal/hinge parts, battery trays (EV), reinforcements.
  
• Forgings: knuckles, yokes, flanges, gears/shafts, connecting rods, stub-axles.
  
• Castings: hubs, carriers, housings, brake discs/drums, pump & e-drive cases (Al).
  
• Rubber/plastic: suspension bushings, bellows/boots, air-intake ducts, washer/expansion tanks, fan shrouds & covers.
  

Data buyers can trust (use as stat badges on the page)

• Auto-component exports: US$ 21.2 B (FY 2023–24); trade surplus US$ 300 M; top lanes USA & Europe.
  
• Foundry scale: India #2 globally; ~12–14 MMT annual casting output; ~4,500 foundries.
  
• Forging capacity: ~3.85 MMT installed in India (AIFI).
  

Bottom line: IndiaUnbox turns India’s press-forging-casting-polymer depth into PPAP-ready parts—with IATF discipline, IMDS compliance, metallurgical QA, and clear cost/lead-time advantages you can defend in a sourcing meeting.
