LCM Process + Preform - MFG PRiME™
LCM Process with Preform Reinforcement: MFG PRiME™
PRiME is our proprietary LCM (liquid composite molding) process for molding with pre-placed reinforcement. It offers many of the same performance characteristics as SMC and similar cost and volume benefits. The key distinction is superior structural efficiency that improves mechanical and cosmetic properties of the molded part. This advantage makes it popular for high-volume automotive and truck parts that require greater structural integrity.
PRiME uses pre-placed reinforcements, precisely aligning the fibers with the load set of the product. This results in improved fiber efficiency and lower cost per weight. Use of advanced robotics minimizes the variation in fiber as well as the labor content, further enhancing performance. These factors expand the design allowables and reduce energy costs by up to 50%.
How does PRiME stack up against SMC?
When comparing the tensile strength of PRiME vs SMC (Figure 2), the averages are very close for both materials — but the range is much tighter for the PRiME part. This is due to more uniform distribution and orientation of the glass fibers. The lower variation allows product designers to use materials very close to their design limits — resulting in stronger, lighter and more efficient parts.
Chevrolet has been using PRiME for the Corvette since 2007 (Figure 3). The PRiME parts reliably meet the essential fiber content and mechanical specifications, yet contain less overall fiber. That makes for lighter, faster Corvettes!
