In the multi-component processing sector, ARBURG is one of the pioneering
companies who have played a significant role in shaping its development since
the beginning of the 1960s. The company has therefore been involved in this area
for more than forty years. Multi-component processing is still a current issue
as new applications are continually arising, largely due to developments in the
material and mould sector.
An interesting application from the field of multi-component processing is the colour-sorted injection moulding of toothbrushes on a special five-component
machine. Toothbrushes with a coloured soft-touch finish are produced as
hard-soft combinations with four colour versions of the soft component. The body
made from PP can be combined with four different TPE colour surfaces in a single
production step, so that the moulded parts, produced by means of multi-component
processing and pre-sorted according to colour, can be further processed and then
packaged.
