How AI Transformed Defect Detection in Automotive Parts Manufacturing
How AI Transformed Defect Detection in Automotive Parts Manufacturing
By Ragalinks Business Solutions Pvt. Ltd.
The Business Problem
A mid-sized automotive parts manufacturer in South India, supplying precision components to Tier-1 auto OEMs, was struggling with rising defect rates and inconsistent quality inspection.
The company relied on manual visual inspection to identify surface defects such as cracks, dents, burrs, or dimension inconsistencies in machined and molded components.
While the inspection team was skilled, the process had several challenges:
Human fatigue and subjectivity leading to variable accuracy.
Increased rejection and rework rates, affecting profitability.
Slow inspection cycles, limiting production throughput.
Customer complaints due to occasional missed defects in shipped batches.
As production volumes scaled up, the management realized that their quality control process needed modernization. They sought a technology-driven solution that could deliver consistent, high-precision inspection while remaining practical and affordable for an MSME-scale operation.
That’s when Ragalinks Business Solutions stepped in, bringing together its business consulting expertise and a digital partner specializing in Computer Vision based AI for manufacturing automation.
The Solution
Ragalinks began with a Business Discovery and Process Assessment workshop to map the inspection flow, identify key pain points, and evaluate readiness for AI adoption.
Based on the findings, a Computer Vision–based automated defect detection system was designed and implemented on the client’s assembly and quality control lines.
The solution involved:
High-resolution industrial cameras strategically placed along the inspection conveyor to capture detailed images of each component.
AI model training using thousands of defect and non-defect images collected from real production data. The model learned to recognize even micro-defects invisible to the human eye.
Real-time inspection dashboard displaying pass/fail results, defect categories, and frequency trends.
Integration with ERP and MES systems for batch traceability and automated quality reports.
Human-in-the-loop validation operators reviewed flagged parts, helping refine AI accuracy over time.
Within six weeks, the AI model achieved over 96% accuracy in defect identification, outperforming manual inspection while maintaining 24/7 consistency.
Ragalinks coordinated the entire initiative from defining the business case and ROI metrics to overseeing implementation, operator training, and post-go-live calibration.
The Benefits
The impact was measurable and multi-dimensional:
Defect detection accuracy improved by 45%, reducing rework and warranty claims.
Inspection time reduced by 65%, increasing throughput without expanding manpower.
Rejection rates dropped by 30%, improving yield and profit margins.
Data-driven quality analytics enabled continuous improvement through trend analysis.
Customer satisfaction increased, resulting in new business orders from existing clients.
ROI achieved in under 8 months, validating technology adoption even for MSME budgets.
The client now operates a digitally enabled, high-precision quality system, positioning itself as a trusted, technology-driven supplier in the automotive ecosystem.
The Ragalinks Perspective
At Ragalinks Business Solutions, we bridge the gap between strategy and execution for MSMEs. Through our digital partner network, we bring affordable, cutting-edge solutions like AI, IoT, and automation to small and mid-sized manufacturers helping them achieve enterprise-grade performance.
This success story reinforces our belief that when MSMEs combine vision, data, and smart technology, they can compete with the best not by size, but by precision, agility, and innovation.
Because the future of manufacturing isn’t just automated it’s intelligent, connected, and empowered.
