When an injection-moulding machine ejects new parts, they may end up on the floor next to, instead of in, the collection container. Although there is nothing wrong with these parts, they are then thrown away. The fact that a part from the machine does not end up in the collection container may sound like an exception at first, but it is not at all uncommon, and above all, the quantity accumulates with the large number of machines used in production.
A significant amount of waste can therefore be saved if the machines and their conveyor belts are optimised. For example, by lids over the collection containers. Other measures are the sealing of gaps with magnetic foil to close the transition from the discharge chute to the conveyor belt. Even if this sounds banal, the sum of the individual measures makes a difference, and in this case unnecessary plastic waste can be reduced.
Magnetic foils seal gaps, e.g. at the transition from conveyor belt and collection container.
Front plates and universal covers ensure that no plastic part is ejected from the machine.
The conveyor belts are centralised and fixed, and hence always run precisely.
Brushes and guide plates direct sprue, good and poor-quality parts into the right track.
In micro injection moulding, the collection containers for good and poor-quality parts are equipped with lids and partition plates.
Due to floor markings and stop wedges, the containers are always at the right position.
