On-Site Supplier Audit Guide — Process Controls, Quality System Verification, Traceability & Capacity Confirmation
A practical guide to what an actual on-site audit visit to a forging supplier's facility should verify — process control evidence at the equipment level, quality system execution rather than paper claims, material and part traceability walked physically through the shop, and honest capacity confirmation.

Evaluating a forging supplier before commitment and auditing that supplier on-site once you're already working together, or seriously considering it, are genuinely different exercises. A pre-commitment evaluation relies substantially on documents, certificates, and answered questions — useful, but inherently second-hand. An on-site audit is where those claims get physically tested: does the shop floor actually run the process controls described on paper, is the quality system something inspectors execute consistently or something that exists mainly for the audit binder, can a part's material and process history actually be traced backward from a finished component to a specific heat and furnace load, and does quoted capacity match what the equipment and shift staffing on the floor can genuinely sustain. None of this shows up reliably in a supplier questionnaire, because a questionnaire records what a supplier says about itself. An audit records what an auditor observes directly — watching an operator actually check a die temperature, watching an inspector actually pull a sample per a documented frequency rather than an ad hoc one, watching how a nonconforming part gets identified and segregated in real time. This guide focuses specifically on what to look for during that physical visit, distinct from the vendor-selection criteria used to decide whether a supplier is worth visiting in the first place.
Ask to see the actual forging operation running — die temperature checks, billet heating soak time, press or hammer setup verification — rather than relying on a slideshow describing the process, since the gap between a documented procedure and shop-floor execution is exactly what an audit exists to find.
Ask to see how a real nonconforming part was identified, segregated, dispositioned, and root-caused recently, with actual records — a supplier's quality system is best judged by how it handles a genuine deviation, not by how clean its procedure manual reads.
Check calibration status stickers on gauges and measurement equipment actually in use at inspection stations, not just a master calibration log in the quality office, confirming the equipment touching your parts is within its calibration interval.
Ask whether operators running critical processes have documented, process-specific training and qualification records, rather than general onboarding training alone, particularly for special processes like heat treatment or NDT.
Pick a random finished part and ask the supplier to trace it backward — through heat treatment records, forging shift and die records, to the specific raw material heat and mill certificate it originated from — a genuine traceability system should support this walk-through without hesitation or gaps.
Observe whether raw material, in-process parts, and finished goods are physically and visibly segregated by status and heat/lot on the shop floor, since mixed or unlabeled material staging is a common source of traceability breakdown regardless of what the paperwork says.
Confirm the press tonnage, hammer capacity, and furnace count actually installed and operational match what was represented during the sourcing conversation, and ask directly what percentage of that capacity is currently committed to other customers.
Ask about actual shift staffing levels and typical daily throughput for parts comparable to yours, since quoted lead times depend on genuine available capacity and staffing, not nameplate equipment capability alone.
A forging supplier audit and a pre-commitment supplier evaluation answer genuinely different questions. Evaluation asks whether a candidate supplier looks capable enough on paper to be worth pursuing, drawing on certificates, questionnaires, and sample parts. An audit asks whether a supplier's actual, ongoing shop-floor practice matches what those documents claim, and that distinction matters because the gap between documented procedure and daily execution is precisely where quality problems tend to originate — a procedure that exists correctly on paper but isn't consistently followed on the floor provides false assurance that only a physical audit reliably exposes.
The most valuable audit findings tend to come from observing real, in-progress work rather than reviewing a prepared presentation: watching an operator actually verify die temperature before a production run, watching an inspector pull samples at the documented frequency rather than an ad hoc one, and watching how a nonconforming part gets caught, segregated, and dispositioned in practice. Asking to trace a recently produced, randomly selected part backward through its full record — from finished part through heat treatment and forging process records to the originating raw material heat number — is one of the single most revealing audit exercises available, because it simultaneously tests traceability, documentation discipline, and process control in a way that's difficult to stage convincingly on short notice.
Capacity confirmation deserves equal attention alongside quality system verification, since a supplier that passes every quality check but genuinely lacks the available equipment time or trained staffing to support your volume within quoted lead times creates a different but equally serious risk. Confirming actual installed equipment against what was represented, asking honestly about current capacity commitment to other customers, and understanding real shift staffing and demonstrated throughput for comparable parts together give a far more reliable picture of delivery reliability than a quoted lead time alone.
For customers who want to audit a forging supplier's actual capability rather than rely on documentation alone, Shivam Forge welcomes facility audits of our Rajkot operation, with full access to process demonstrations, traceability records, and quality system execution. Contact our engineering team at +91-9265772827 or sales@shivamforge.com to schedule an audit or discuss your specific verification requirements.
Pre-selection evaluation relies mainly on documents, certificates, and questionnaire answers submitted by the supplier. An on-site audit physically verifies those claims by observing the process running, checking records at the point of use, and tracing traceability through the actual shop floor — it's a confirmation exercise rather than an initial screening exercise.
This depends on component criticality and any changes at the supplier, but an annual audit cadence for critical suppliers, with a triggered audit after any significant quality escape, process change, or ownership change, is common practice. Lower-criticality suppliers may reasonably be audited on a longer interval.
Tracing a real, recently produced part backward through its full record — material heat, forging process parameters, heat treatment, inspection results — tends to reveal more about a quality system's actual health than any other single check, since it exercises the traceability, documentation, and process control systems simultaneously and can't be faked convincingly on the spot.
Announced audits are standard practice and allow the supplier to make relevant records and personnel available, which generally produces a more useful audit than an unannounced visit that may catch staff unprepared to pull specific records. A well-run announced audit that asks to see real, recent records rather than curated examples achieves most of the same verification value.
Yes. We regularly host customer quality audits of our Rajkot facility, including process demonstrations, traceability walk-throughs from raw material to finished part, and full access to relevant quality records — contact our team to schedule one.
