Cost-effective and extremely flexible: Openair® Plasma facilitates 2C injection molding of children’s toys that is free of toxic materials

Two-component (2C) injection molding refers to a two-stage manufacturing process using injection molding. First, a hard component is formed that is then coated selectively with a soft component in a second step. If the materials are compatible, these two components form a strong bond.

This process has been rarely used in the manufacture of children’s toys, however, because only certified materials free of any toxins can be used, similar to medical technology. But as a rule, soft components don’t bond well to such materials.

With Openair® Plasma pre-treatment, however, 2C injection molding can be used by the toy industry without worry and without toxic materials. This plasma system is integrated directly in the extrusion tool and selectively modifies the exact spot where the soft component will be subsequently bonded (plastic bonding agent).
