Video: Direct Coating Technology Combines Injection Molding And Spray Painting
The component itself can be transparent, translucent or opaque. Its surface can be varnished in different colors, decorated with a matt varnish or piano varnish look or protected with scratch-resistant functional coatings. There are also various options for haptic design and surface structuring. This shows another advantage of the DirectCoating process compared to spray painting: With the injected paint, contours such as sharp edges, curves or raised areas can also be displayed because it reproduces the tool surface in great detail. One variant is fine grain with sharply defined high-gloss and matt areas.
Based on a material data set created by Covestro for the simulation with Moldflow, the filling of the tool with the polyurethane varnish can be calculated in advance. The simulation model takes various influencing factors into account. This can prevent air pockets, for example. The model has now been tried and tested to such an extent that Covestro offers its customers and their toolmakers, as part of projects, to calculate the optimal sprue and vent design for the paint component.
