Quality Assurance
Rigorous testing at every stage of the casting process
Our Laboratories
Advanced testing infrastructure ensures every casting meets international standards and customer specifications.
Metallurgy Lab
Equipped with a spectrometer for precise chemical composition checks and an optical microscope with Image Analyzer software for in-depth microstructure analysis.
Mechanical Testing Lab
Rockwell hardness testing machine and a Universal Testing Machine (UTM) to guarantee the highest standards of strength and durability in our castings.
Sand Testing Lab
Rigorous assessment of moulding and core-making sand quality — testing moisture content, permeability, and strength to ensure optimal results.
ISO 9001:2015 QMS
Certified by TUV SUD (Certificate No. 99 100 22638). Every batch undergoes metallurgical analysis, dimensional inspection, and mechanical testing.
Dedicated & Strong Team
Our workforce includes experienced foundry engineers, metallurgists, quality controllers, skilled technicians, and dedicated marketing and logistics personnel. Continuous training and process audits ensure adherence to best practices and safety norms.
Frequently Asked Questions
What quality certification does the foundry hold?
Sri Gnanamurugan Foundry holds ISO 9001:2015 certification issued by TUV SUD under certificate number 99 100 22638.
What testing equipment do you have in-house?
The in-house laboratory covers spectrometer analysis for chemical composition, Rockwell hardness testing, a universal testing machine for mechanical properties, an optical microscope with image analyser for microstructure, and a sand testing laboratory.
At what stages are castings inspected?
Quality is checked throughout the process rather than only at the end — chemical composition is controlled at the melting stage, sand properties are tested for moulding, and hardness, mechanical and dimensional inspection are carried out on every batch before dispatch.
