[Case Study] Molding of Elastomer Resin with Complex Three-Dimensional Shapes
Achieving complex three-dimensional shapes that cannot be mass-produced! Molding technology that does not compromise the designer's intent at all.
We would like to introduce a case where we successfully mass-produced a beauty brush with a complex three-dimensional shape that was deemed impossible to mold. This product features a special three-dimensional skeleton structure that manufacturers both domestically and internationally had given up on, stating that "the mold structure is too complex for mass production." By applying the advanced mold design know-how cultivated through high-difficulty in-mold processes to general molding, we constructed a special mold structure that clears complex undercuts. We succeeded in mass-producing products for major brands. 【Case Overview】 ■ Challenges Faced: The mold structure for the beauty brush with a special three-dimensional skeleton structure was too complex for mass production. ■ Solution: We applied advanced mold design know-how to general molding and constructed a special mold structure that clears complex undercuts. ■ Value Created: Successfully mass-produced products for major brands without compromising the designer's design. *For more details, please download the PDF or feel free to contact us.
