QUALITY ENHANCEMENT AND PROCESS AVAILABILITY IN LLDPE STRETCH FILM OUTPUT BYMULTISENSORS AND COMPUTERIZED SYSTEMS

Objective


The consortium being well structured with a strong participation of SME's and including raw material supplier, end product producer and dealer, with a very good balance between industries and research centres, has allowed to reach the results proposed with particular attention to costs reduction and quality improvement.
The innovative aspect of the project, concerning the factory integration, has led to the application of the CIM concepts to a very competitive production process with a considerable contribution of the advancement of the extending technique.
Development of factory complete automation with all actions working under control is designed to improve product quality and process availability. To assure high quality and good availability some critical areas will be pinpointed and studied in an experimental way and simulated with the purpose of prototyping the whole process.

Once scientifically analyzed, tested and optimized, the results will provide a comprehensive system able to improve the stretch film features and to integrate the new technology perfectly.

To make the design a reality, manufacturing interprets the product definition data to plan the orderly sequence of events that must occur to convert the "raw materials specifications" into a "production definition data document". The only way of doing this is to change the work organization and to improve the technology - automation is preeminent and CIM is the solution.

By this approach CIM can achieve its purpose and a programmable automation system provides the best means of leveraging both the information assets and fixed assets of manufacturing enterprise.

In particular: product and process control and performance, data flow and SW/HW integration, factory communications.

In order to achieve these objectives the research has highlighted the main critical areas attempting solutions that represent significant advances on current and foreseen practices in the scientific applied field:
- new CIM architecture implementation, - new extruder process control, - multilayer measurement control, - chill roll and pre-stretching improvement, - stochastic analysis, - extruder process simulations;

Tests and practical proofs will confirm the results and will give greater efficiency to the specific field.
