Topic: Atmospheric plasma as plastic bonding agent. 2C injection molding free of toxic materials appropriate for children’s toys.
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).
