QUALITY ASSURANCE

 Quality Control and R&D sections are well equipped with sophisticated instruments such as Atomic Absorption Spectrophotometer, Flame Photometer, Ramp Pressure Tester, Vertical Load Tester, Profile Projector, Impact Tester and Automatic Thermal Shock Tester, which contribute to produce international quality containers.

With a strong Quality Control System in place (ISO-900/2000), we have been able to achieve

• Quick identification and rectification of defects
• Substantial reduction in job changeover and job upbringing time
• Shift from-Break Down Maintenance to Preventive Maintenance Philosophy.
• Higher KCR of 148 in 2005 as against 129 in 2000
• PTM increased from 76% in 2000 to 86% in 2005

The design cell of HNG group is equipped with CAD-CAM facilities for designing and manufacturing moulds and mould accessories, and is ready to offer containers of unique shapes and sizes in various colours. Amber, Flint and Green (including Georgia Green) are the different colours offered, while sizes vary from 5 ml to 3200 ml. HNG group manufactures over 500 kinds of glass containers to cater to a diverse range of applications.

QUALITY CHECKS

• Check over incoming raw materials and packing materials.

• Tight Glass Density Control as a routine tool for glass properties monitoring.

• Frequent Glass Analysis.

• Tight on-line Quality Checks through. Computerized, Camera based and Light-based  Automatic Inspection Machines followed by visual inspection.  

• Strength Tests to control Thermal Shock Resistance, Internal Pressure, uniformity of glass distribution, stacking strength and stress control (annealing) .

• Use of Statistical Quality Tools before final release of Products.

• Strong feedback loop to minimize defects at manufacturing stage itself.
