Capability Checklist for Your RFQ

Before you issue RFQs to sheet metal fabricators in Bangalore, compile this dossier to improve quote accuracy and comparability:

• Design Files: STEP/IGES, flat patterns (DXF/DWG), assembly PDFs with GD&T.

• BOM & Materials: Alloy/grade, thickness, grain direction, material treatment specs.

• Critical-to-Quality (CTQ) Features: Tolerances, cosmetic surfaces, weld aesthetics.

• Finishing: Powder RAL codes, anodizing thickness, salt spray requirements, masking zones.

• Hardware: PEM fasteners, studs, captive nuts—call out specs and installation direction.

• Packaging: Individual wraps, corner guards, desiccants, EPE foam, palletization.

• Testing: Fit checks, FAI, leak tests, load tests, surface roughness, adhesion.

• Volumes & Cadence: Prototype qty, ramp plan, EAU, releases (monthly/quarterly).

• Delivery Terms: Incoterms, delivery frequency, kanban expectations.

How to Compare Quotes (Beyond Price)

Price matters, but a low number can hide risk. Benchmark each vendor on:

• Yield & Nesting Strategy: Ask how they minimize scrap on your sheet sizes.

• Setup Reduction: Do they combine jobs or use common tooling to reduce changeover?

• Bend Sequencing: Will your design require special fingers/dies or creative sequencing that adds time?

• Fixture Philosophy: Robust, mistake-proof fixtures imply stable quality in scale.

• Weld Heat Input Control: Especially for thin gauge stainless or aluminum, distortion control is a differentiator.

• Coating Line Loading: Can they ensure uniform coverage and avoid Faraday cage effects?

• Rework Handling: Clear MRB/NCR processes reduce surprises and delays.

Create a simple weighted scorecard (example weights shown):

Score each supplier 1–5 per row, multiply by weight, and sum for a final comparison. This makes justification to stakeholders straightforward.

Evaluating Quality Systems

Ask for and review:

• Certificates & Scope: Verify current ISO/IATF/AS9100 certificates and exact scope (processes, locations).

• Sample Control Plans: For production jobs, request a CP and PFMEA; check CTQs align with your drawing.

• Inspection Records: See real examples—FAI reports, CMM data, weld PQR/WPS.

• Gage Strategy: GR&R evidence for critical measurements.

• Change Management: ECO/ECN logs, revision control discipline, and part marking practices.

Lead Times You Can Expect (Typical, Not Promises)

• Prototypes: 3–7 working days if material is common and finishes are simple.

• Small Batches (50–200 units): 1–3 weeks depending on coating/plating queues.

• Production Runs (500+): 3–6 weeks; quicker with blanket orders and forecast schedules.

Lock these with the vendor in a Master Service Agreement along with OTD and PPM targets.

Logistics Advantage: Bangalore Layout

Choosing a fabricator near your plant or final customer reduces transit time and handling damage. Rough heuristics:

• Peenya / Nelamangala: Dense cluster, rapid access to skilled labor and machine shops.

• Bommasandra / Jigani: Strong for medium-heavy fabrication and integrated finishing.

• Whitefield–Hoskote: Good for tech hardware, electronics enclosures, and export connectivity.

Brands increasingly ask for:

• RoHS/REACH compliance for materials and coatings.

• Powder Coating VOC management and energy-efficient ovens.

• Wastewater treatment and sludge disposal documentation for finishing lines.

• ESG reporting: Basic KPIs like energy per part and scrap rates.

If sustainability is a brand pillar, make it part of your scorecard.

Red Flags to Watch For

• Quotes that omit finishing specs or assume “standard” without listing RAL/microns.

• No mention of inspection beyond final visual checks.

• Resistance to FAI or to sharing sample control plans.

• Over-promising on lead time with no capacity explanation.

• Poor documentation hygiene: mismatched revisions, missing drawing sign-offs.

Example: How a Shortlist Might Look (Illustrative)

Imagine you’re sourcing a powder-coated aluminum enclosure (5052-H32, 2.0 mm, PEM hardware, cosmetic faces, RAL 9005 matte). After an RFQ to six vendors, you narrow to three:

1. Vendor A — Prototype-to-Production

   • Strengths: Fast DFM feedback, tight bend control on 2.0 mm aluminum, in-house PEM insertion, quick powder line changeovers.

   • Considerations: Limited anodizing; partners for plating add a week if needed.

   • Best for: Rapid prototypes and first three batches with frequent engineering changes.

2. Vendor B — High-Precision Specialist

   • Strengths: AS9100, CMM-heavy inspection, strong weld distortion control, flawless cosmetic finishing.

   • Considerations: Higher piece price; prefers stable drawings.

   • Best for: Premium enclosures where cosmetics and tight GD&T dominate.

3. Vendor C — Volume Contract Manufacturer

   • Strengths: Robotic welding, automated panel bender, takt planning, stable OTD in thousands/month.

   • Considerations: Minimum order quantities, longer NPI; requires PPAP.

   • Best for: Mature designs with predictable, recurring demand.

By mapping your forecast (e.g., 50 prototypes → 300 pilot → 2,000/quarter steady state), you might start with Vendor A, qualify Vendor B for a premium variant, and nominate Vendor C for scale once ECOs stabilize.

Negotiation & Partnership Tips

• Bundle SKUs with common material and finish to unlock price breaks and shared setups.

• Supply Material or Allow Substitution where acceptable (e.g., 5052 ↔ 5005 for coating uniformity) to improve availability.

• Design for Coating: Add drain/vent holes and masking notes to cut rework.

• Tooling Investment: Simple brake tooling or fixtures pay back quickly through reduced cycle time/variation.

• Vendor Managed Inventory (VMI): For repeat parts, VMI or kanban bins cut your lead time and safety stock.

FAQ: Sheet Metal Fabrication in Bangalore (2025)

Q1: Are online instant quotes reliable?
They’re great for ballparking and for simple parts. For assemblies, cosmetic faces, or tight GD&T, insist on engineer review and a formal quote.

Q2: How do I protect cosmetic surfaces?
Call out grain direction, protective film, and packaging. Specify no-touch zones and masking for coating.

Q3: How early should a fabricator join design?
As early as bend radii and fastener strategy are decided. Early DFM avoids downstream rework and surprise costs.

Q4: What’s the most common cause of delays?
Ambiguous drawings/finishing specs and late hardware/material availability. Clear RFQs and flexible alternates reduce risk.

Q5: Is dual-sourcing worth it?
Yes—qualify a secondary vendor for continuity. Share the same FAI pack to keep parts interchangeable.

Final Takeaway

Bangalore offers one of India’s most capable, cost-effective ecosystems for sheet metal fabrication in 2025. Instead of chasing the lowest unit price, build a structured comparison around capabilities, quality systems, DFM depth, and capacity fit for your demand curve. Start with fast, DFM-savvy shops for prototypes, qualify a precision specialist when tolerances or cosmetics tighten, and transition to a volume player once the design stabilizes. This staged approach de-risks your launch, keeps lead times tight, and protects quality—while still delivering total landed cost advantages.
