One Partner,
Every Material, Every Process.
From silicone + plastic to silicone + metal, YMS integrates molding, insert bonding, procurement, and assembly into a seamless production flow for complex multi-material products.
Silicone + Plastic
Seamless Hybrid Molding with PP, ABS, and PC.
Our dual-shot and over-molding processes allow silicone to bond permanently with hard plastics, delivering products that combine structural rigidity with soft-touch functionality.
-
Two-Shot Injection Molding
Precise bonding between silicone and thermoplastics in a single cycle.
-
Compatible Materials
PP, ABS, PC, PA, TPE -- selected based on functional requirements.
-
Strong Adhesion
Verified via pull and peel testing -- no delamination over long-term use.
Silicone + Metal
Durable Composite Structures with Stainless, Aluminum & Zinc Alloy.
For products demanding strength, weight, or thermal stability, we combine silicone with precision-machined metal parts through insert molding and mechanical bonding.
Insert & Over-Molding
Permanent Bonds Between Dissimilar Materials
Our in-house capabilities cover the full insert bonding workflow, ensuring molecular-level adhesion between silicone and inserts of plastic, metal, fabric, or electronic components.
Insert Molding
Pre-placed metal or plastic inserts fully encapsulated in silicone.
Over-Molding
Soft silicone layer bonded over rigid plastic cores for grip and comfort.
Bonding Treatment
Primer coating & plasma treatment ensure chemical-level adhesion.
Mechanical Lock
Undercut, groove, and through-hole designs for lock-in strength.
Project Management
Managing Complexity Across Every Process Node.
A dedicated project manager owns your timeline from day one -- coordinating molding, assembly, surface treatment, and compliance under a unified schedule.
Design Review
DFM analysis and material compatibility assessment.
Tooling
Parallel mold development for silicone & structural parts.
Sampling
T1-T3 samples, functional testing, and client confirmation.
Production
Mass production with real-time QC and milestone reporting.
Delivery
Packaging, inspection, and global logistics coordination.
Mold & Positioning
Precision Tooling Where Materials Meet.
Multi-material molds demand perfect alignment. Our in-house tool shop builds precision positioning systems that guarantee repeatability across millions of cycles.
Procurement
An Integrated Supply Chain, Managed by Us.
We handle the sourcing, auditing, and quality control of every non-silicone component -- so you receive a finished product, not a parts list.
