In-Mold Painting for Long-Fiber; Plastic Technology

June 7, 2016

For plastic technology in terms of the design of automobile/machinery parts, in-mold painting for long-fiber offers a variety of advantages over methods that were previously available.

In-mold painting for long-fiber is a fairly newly available in-mold process for painting that makes the manufacture of polyurethane composite components of automobile parts and agricultural machinery pieces possible. This is an in-mold painting process that was developed so that smooth surfaces could be achieved thanks to long fiber technology. Smooth surfaces are often advantageous not only for the functionality of these parts, but also when it comes to the aesthetics of the parts’ appearance.

With in-mold painting, a paint layer is applied right on an open mold’s surface. This is great for achieving the smooth surface manufacturers want for composite parts of buses, trucks, cars, and pieces of machinery.

The in-mold painting for long-fiber process results in reinforced polyurethane composite that is long glass. Thanks to a barrier coat that’s applied in addition to the paint, parts with high-strength are achieved. The barrier coat that’s placed in addition to the paint job will stop glass fibers from appearing in the paint. This results in the superior smoothness that the technique is known for.

Past technique of applying paint in this type of situation used a process whereby glass mix was poured into a film. This newer process is attractive for a variety of reasons. One reason in-mold painting for long-fiber is superior is because it is possible to use the technique efficiently even with a project that has fairly low volume production targets.

Also, the method is better suited to projects where the flexibility of creating a certain design is important. In-mold painting for long-fiber projects in plastic technology makes it possible to achieve a wider variety of different designs than previous methods.
