Quality Assurance
Quality Assurance System
Quality at Nagasai Industries Pvt. Ltd. is governed through a structured ISO 9001:2015 Quality Management System covering tooling, component manufacturing, and rubber moulding operations.
The system emphasizes process control, inspection discipline, and consistent execution.
Quality Objectives
- Deliver press tools and components as per customer drawings and specifications
- Maintain dimensional accuracy and functional reliability
- Ensure repeatability in production
- Prevent defects through inspection and controlled processes
Quality Control Approach
Incoming Material Control
- Tool steels and raw materials selected based on application requirements
- Standard components and consumables sourced from approved suppliers
- Materials verified before use in manufacturing
In-Process Inspection
- Inspection after machining of plates, inserts, and punches
- Inspection during fitting and assembly of press tools
- Inspection during trial and validation stages
Final Inspection
- Verification of dimensional accuracy
- Functional fitment checks
- Visual inspection for damage or defects
- Clearance only after inspection approval
