Advanced Molding Services
From concept to production, our end-to-end molding capabilities cover every stage of multi-material component manufacturing.
Over Molding
Bond TPE, rubber, or soft-touch plastic over a rigid substrate. Achieve superior grip, vibration damping, and aesthetic differentiation in a single automated cycle.
Learn More →Insert Molding
Encapsulate metal inserts within plastic housings. Eliminate secondary assembly, achieve >50 kN pull-out forces, and reduce part count by up to 60%.
Learn More →Multi-Shot Molding
Two or more materials injected in sequence within one mold. Perfect for color separation, functional zones, and chemical-bond interfaces without adhesives.
Learn More →Medical-Grade Molding
