Sensor Solutions to improve production effciency
B The rubber and plastics industry provides products to a multitude of other indus-
trial sectors. In particular, the automotive, electronics, and white goods industries,
as well as the packaging industry have a signifcant infuence on the development
C of this industrial sector. However the medical, sports, and toy industries also rely
on rubber and plastics products.
Various types of production processes and machines such as injection molding
D machines, extruders, flm and foam systems, and thermoforming machines are
used to serve this variety of industry requirements. Various materials such as
granulates, liquids, and semi-fnished products are processed in different, to some
E extent automated processes.
Since production is done on a very large scale, the highest degree of effciency
and economy as well as quality and safety are required.
F With its industry and sensor expertise, SICK makes a signifcant contribution
toward fulflling these requirements.
