At SNMPPL, Quality is not just a process – it is one of our core values.

We believe consistent quality is the key for Growth of any organisation, that builds repeatable and long-term business relationship.

We follow defined inspection stages and controlled manufacturing processes to ensure every part we produce meets customer specifications to ensure accuracy, consistency, long-term supply stability and complete traceability.

Quality Management System

We are ISO 9001:2015 certified, accredited by TÜV SÜD, and our Quality Management System covers the complete lifecycle – from incoming raw material verification to final inspection and dispatch, ensuring consistent quality, traceability, and continual improvement.

Our QMS ensures

Compliance with customer drawings, specifications, and applicable internationally accepted inspection and tolerance standards

Controlled and repeatable manufacturing processes

Defined inspection and approval stages

Traceability, documentation, and corrective action systems

Continual improvement through audits, reviews, and performance monitoring

Quality Flow Diagram

This flow shows how we control quality at every stage – from raw material inspection to final dispatch – to ensure consistent and reliable supply.

Incoming Material Inspection

Dimensional, visual & certification verification

First Article Inspection (FAI) / Set-Up Approval

Validation against approved drawings and specifications

In-Process Monitoring

Hourly / defined interval checks to ensure dimensional stability

Control of Critical Characteristics (CTQ)

Monitoring of critical dimensions, process parameters, and tool condition

Batch Traceability & Documentation Control

Batch identification & inspection record control

Final Inspection & Release

AQL-based sampling and verification prior to dispatch

100% Visual Inspection

Surface and finishing verification as applicable

100% Visual Inspection
