Maintains clarity and flexibility over years of outdoor exposure
Provides excellent water and dust sealing
Enhances aesthetic durability with color stability
5. Electrically Conductive LSR Overmolding for EMI/RFI Shielding
Electromagnetic interference (EMI) and radio-frequency interference (RFI) can compromise signal integrity. Conductive LSR formulations incorporate metal fillers to provide electromagnetic shielding.
Benefits:
Protects sensitive electronics from interference
Enables grounding and electrical continuity
Maintains flexibility and durability
6. Custom Color and Branding Integration with Overmolding
Brand identity and visual differentiation are vital in complex systems. Custom color overmolding solutions allow for branding, coding, and visual cues directly integrated into the connector design.
Key Features:
Wide color palette options
Incorporation of logos or text
High color stability and fade resistance
7. Flexible, Soft-LSR Overmolds for Ergonomic and Safety Features
In applications requiring manual handling, soft and flexible LSR overmolds improve grip, ergonomics, and safety.
Advantages:
Reduces operator fatigue
Provides slip resistance
Absorbs shocks and vibrations
8. Flammability-Resistant LSR Overmolding for Safety-Critical Applications
Fire safety standards are increasingly stringent. Flame-retardant LSR formulations meet UL94 V-0 and other safety certifications, providing fire-resistant overmolding solutions.
Features:
Self-extinguishing properties
No toxic fumes upon combustion
Maintains electrical insulation during exposure
9. High-Precision Micro-Overmolding for Miniaturized Connectors
Miniaturization demands micro-overmolding techniques capable of producing high-precision, intricate features at microscale.
Benefits:
Ensures tight tolerances for compact connectors
Facilitates integrated sealing and strain relief
Supports automated manufacturing for high-volume production
