Eliminate Contamination from Intricate Technical Mouldings
During manufacture of intricate medical, optical or technical mouldings, robots are often used to pick up the components from the injection mould tool and place them on a transport conveyor to the next operation. Whilst the component cools it will likely electrostatically charge, causing unwanted contaminant attraction.
Where the nature of a moulding’s intricacy or final required quality dictates that it should be kept contamination free during its manufacture, manual handling is often replaced by robotic manipulation.
After the robot picks the medical, optical or technical component from the injection mould tool, it is typically placed upon a transport conveyor that takes the part either onto a process line or a collation point. Whilst the component cools it will likely electrostatically charge, causing unwanted contaminant attraction.
Eliminate Contamination from Intricate Technical Mouldings - Select a problem:
Enclosing the conveyor and positively pressurising the tunnel with laminar-flow air from fan filter units (FFUs) will keep unwanted particles away from the components during cooling and transportation along the conveyor. However, the cooling and the airflows can create a static charge. At both the entry and exit points of the tunnel, the components can be exposed to contamination attraction.
By fitting 1250-S, 3014 or 3024F short range ionising bars across both gates of the tunnel, the exiting airflow becomes ionised, thereby preventing component charging and contaminant attraction.
Larger volume units will use a 3024L inside to neutralise the air and the product.
