Polymer Processing Techniques Quality Assurance and Quality Control (QA/QC)equipment operationspolymer material testing
To ensure that all polymer raw materials, in-process materials, and finished products meet the specified quality standards through systematic sampling, testing, and documentation, supporting continuous quality improvement in the manufacturing process.
Key Responsibilities:
1 Raw Material Testing:
Inspect and test incoming raw materials (resins, additives, pigments) as per defined parameters.
Ensure supplier compliance with quality standards.
2 In-process Quality Checks:
Conduct in-process checks during extrusion, molding, compounding, and other stages.
Monitor process parameters and ensure adherence to SOPs.
Identify deviations and report immediately to production and QA teams.
3 Finished Product Testing:
Perform mechanical, thermal, and physical testing (tensile strength, elongation, MFI, density, hardness, etc.) of finished goods.
Ensure finished products meet customer and company specifications.
4 Documentation & Reporting:
Maintain detailed QC records (test reports, inspection records).
Update daily QC reports and maintain traceability of materials.
Support ISO, BIS, and customer audits with proper documentation.
5 Calibration & Maintenance:
Ensure all QC instruments (MFI tester, UTM, DSC, etc.) are calibrated and functioning.
Perform basic troubleshooting of lab equipment.
6 Non-Conformance Handling:
Identify non-conforming products and communicate with production for corrective action.
Participate in root cause analysis and corrective/preventive actions (CAPA).
7 Support Quality Improvements:
Participate in continuous improvement initiatives.
Support implementation of 5S and lean practices in the QC lab.
8 Safety & Compliance:
Follow safety guidelines in handling chemicals and lab equipment.
Adhere to company policies and quality systems.
Key Skills Required:
Knowledge of polymer material properties and processing
