Key Features & Benefits:

Unbreakable Bond: Achieve a permanent, molecular-level bond between silicone and PC without adhesives.

Enhanced Ergonomics: Create comfortable, non-slip grips for tools, medical devices, and consumer electronics.

Superior Sealing: Excellent resistance to water, dust, and chemicals for robust IP-rated enclosures.

Durability: Combine the impact strength of PC with the tear/abrasion resistance of silicone.

Aesthetic Versatility: Available in a wide spectrum of colors, textures, and hardness levels (Shore A).

Detailed Manufacturing Process:

The overmolding is a two-shot or insert molding process. First, the rigid PC substrate is injection molded. This "pre-form" is then placed into a second mold cavity where liquid silicone rubber (LSR) or high-consistency silicone rubber (HCR) is injected over it.

PC Molding: PC is processed at high temperatures of 280°C - 320°C with injection pressures of 800 - 1,500 bar.

Silicone Overmolding: LSR is typically processed at lower temperatures of 160°C - 200°C with precise control over injection pressure (150 - 500 bar) and cure time to ensure perfect bonding without distorting the PC part. The mold itself is often heated to 120°C - 180°C to facilitate curing.

Post-Process & Quality:

Finishing: De-flashing, visual inspection, and 100% functional testing to guarantee bond integrity.

Quality Assurance: Our partner facilities hold ISO 9001, ISO 13485 (Medical), and IATF 16949 (Automotive) certifications, ensuring full traceability and compliance for the most demanding industries.

Cost Advantage (VAVE):
Our deep manufacturing expertise allows us to conduct Value Analysis & Value Engineering (VAVE) from the design stage, optimizing part geometry, material selection, and tooling design to reduce unit costs without compromising quality.
