QUALITY AND LEAN APPROACH

Lean Six Sigma

The introduction of the Lean Manufacturing process, has improved production efficiency and flexibility as well as increased each phase of quality control. The LEAN MANUFACTURING process has been implemented in the VISA production cycle with the scope of improving work phases and reducing delivery times while maintaining elevated quality levels. The assembly islands have been organized according to genset size, designed to increase efficiency in line with the continuous improvement process.

TARGET: REDUCE LEAD TIME AND IMPROVE PRODUCTION EFFICIENCY

• New Production Layout: assembly island:
• Ordered, practical and ergonomical workstation
• Improved component/materials logistical management
• Small components found within island for quicker access
• Assembly areas re-organised to suit “Just in Time” production needs
• Trained and empowered Operators

TESTING AREA – THE QUALITY HEART OF THE FACTORY

At the end of the manufacturing process, every single unit goes to our modern test room where it is subjected to a load test, according to ISO quality procedures:
• Each test lasts 45/60/120 minutes (according to product version)
• Mechanical checks;
• Simulation of alarms and protections installed in the genset
• Different steps test: 10%, 25%, 50%, 75%, 100% and 110% of load;
• All gensets have their own test certificate, signed by our technicians

Star

With star the start of each of the three phases is connected together. Connections are taken from the ends of the three phases to give the three phases

Delta

With Delta the starts and ends of the phases are connected. The end of phase 1 is connected to the start of phase 2, the end of phase 2 to the start of phase 3, and the end of phase 3 to the start of phase 1. Connections are taken from the three start-end points to give the three phases.
