At ETA Manufacturers, quality is not a department — it is a discipline embedded in every stage of our production process, from incoming raw material inspection to final dispatch. We recognise that the castings we produce go into applications where failure is not an option. This awareness drives our approach: every casting is produced as if it were going into the most critical application.
Our quality philosophy is built on three principles: prevention over detection (getting it right the first time), complete traceability (every casting traceable to its heat, material, and test results), and continuous improvement (systematically reducing variation and defect rates through data-driven process control).
Our Quality Management System is certified to ISO 9001:2015 and covers all aspects of our operations — from contract review and raw material procurement through production, inspection, and dispatch. The QMS provides the framework for:
Documented Procedures: Standard Operating Procedures (SOPs) for every process — melting, moulding, pouring, heat treatment, machining, and inspection.
Incoming Material Control: All raw materials — scrap, alloys, sand, resin — are inspected and verified against purchase specifications before release to production.
In-Process Inspection: Quality checkpoints at each production stage — mould assembly, pouring temperature, heat treatment cycle parameters, and post-knockout visual inspection.
Final Inspection & Testing: Every casting undergoes visual inspection, dimensional verification, and material testing (as applicable) before dispatch approval.
Non-Conformance Management: Systematic identification, segregation, root cause analysis, and corrective action for any non-conforming product.
Customer Feedback & CAPA: Formal system for recording and acting on customer complaints, with Corrective and Preventive Action (CAPA) processes.
Our in-house laboratory is equipped to carry out the full range of tests required by our clients and inspecting agencies, including RDSO, RITES, and third-party inspection bodies.
In addition to routine production testing, we support the following inspection protocols:
Third-Party Inspection: We regularly host inspection visits from RDSO-appointed inspecting officers, RITES engineers, client QA teams, and independent third-party agencies (TUV, Bureau Veritas, SGS, etc.).
Stage Inspection: For critical orders, we facilitate stage-wise inspection (raw material, in-process, heat treatment, final) as specified by the client or inspecting authority.
Material Test Certificates (MTC): Every consignment is accompanied by a comprehensive test certificate documenting chemical composition, mechanical properties, heat treatment details, and NDT results as applicable.
We maintain rigorous process control at each production stage through a combination of documented procedures, trained operators, and systematic monitoring:
