Long fiber injection is a process in which polyurethane resin and chopped fiberglass are poured into an open mold. Low compression pressure is then used to create complex parts in a variety of sizes.
In components produced using the LFI process, the reinforcing fibers create an “internal skeleton,” maintaining durability even alongside the increase in stiffness. The structure of the fibers dissipates stress forces, allowing the material to withstand heavy or repeated impact without deforming or cracking.
The LFI allows for in-mold painting, reducing the need for time-consuming post molding paint jobs. It also allows for the creation of complex geometric structures as well as the addition of B-side geometry such as ribs and bosses. B-side geometry compliments LFI’s existing advantages by making parts even more stable and durable and saving material cost by pairing thinner walls with enhancements such as ribbing.
