LeRouge Precision Pen Molds: Infusing "Micron-Level" Accuracy into Beauty Tech


In the automated production of cosmetic pens, the precision of the mold dictates both product quality and manufacturing efficiency. LeRouge provides high-performance tooling solutions engineered for excellence.


  • Integrated Molding & Insertion: Our integrated molds realize synchronized alignment for "filling-cooling-insertion," significantly reducing secondary contamination and positional deviations found in traditional methods.


  • Side-Filling Expertise: The unique side-filling design ensures full material occupancy without air bubbles. Combined with high-precision venting structures, it delivers perfect tip shapes for every eyebrow pencil.


  • Automation-Ready Design: Engineered specifically for high-speed lines, our auto-machine molds feature superior wear resistance and consistency, withstanding high-frequency cycles and thermal fluctuations for 24/7 stable operation.


  • CNC Craftsmanship: Each mold set is crafted from aviation-grade alloys via 5-axis CNC machining. We ensure a mirror-like finish in every cavity, allowing for effortless demolding and a pristine product surface.
