Samdong Industrial, a long-established film extrusion company that has been in business since 1970

Casting Extrusion

Core Technology
Samdong Industrial introduces high quality products
to the market
using casting extrusion processing
technology.

Casting extrusion processing is a method of forming a film after melting the resin
in an extruder, passing it through a T-shaped die, and contacting the cooled roll
surface with the resin. The technology boasts excellent standard stability and
productivity. Samdong Industrial is introducing a new level of cast film products to
the market through world-class casting extrusion facilities.
