Not To Be Missed – Zero Defect Moulding Presentation at Interplas 2017
On the Interplas “Introducing Stage” at 14:00 on the 28th September, Kistler Application Engineer, Duncan Webster, will be delivering a paper on the latest developments of the Kistler ComoNeo cavity pressure monitoring system.
Cavity pressure monitoring is a well proven technique for identifying cavity fill problems in real time so that out of specification products can be identified and rejected and moulds protected from damage due to overfilling. This paper describes the latest systems that use cavity pressure profiles to control the injection process to minimise incorrect cavity filling and so reduce rejects. These systems control the injection moulding process and balance the hot runner system, irrespective of the machines, moulds and peripherals used.
Cavity pressure monitoring allows process fluctuations to be corrected during the moulding phase in real-time as the process control system optimises the switchover point for all the cavities, resulting in balanced injection behaviour across the entire production sequence. The system synchronizes the pressure profiles by individually controlling the nozzle temperatures on the hot runner, stabilising the process by adjusting for batch fluctuations and other process conditions.
The new approach to production focuses on consistent digitisation leading to enhanced product quality and increased cost-efficiency. Moulders using these new techniques are ideally placed to meet the requirements for digital networking demands of Industry 4.0.
This key advantage, compared with systems based on melt front detection, makes the process control more accurate and provides additional benefits for the user.
With over 25 years practical experience within the plastics industry, Duncan Webster has in-depth knowledge of a wide range of materials and processes from short run prototyping through to high volume automated production to bring real world experience to bear on the problems faced by injection moulders.
