Description

Product Overview

Custom LSR overmolded PCB silicone covers are designed to protect electronic circuit boards from moisture, dust, vibration and environmental impact.

Liquid silicone rubber is directly molded onto the specified PCB or electronic substrate area to create an integrated protective structure.

Compared with traditional assembled silicone covers, LSR overmolding reduces assembly steps and provides stable sealing performance for electronic applications.

SiliconePlus supports custom silicone overmolding development based on PCB drawings, samples and application requirements.

Why Use LSR Overmolding for PCB Protection

Electronic modules often require reliable protection without increasing assembly complexity.

LSR overmolding provides:

• Waterproof protection
• Dust resistance
• Shock absorption
• Flexible silicone protection
• Stable dimensional performance
• Integrated silicone-to-substrate bonding

For customized electronic silicone sealing solutions, you can also review our silicone over FPC and silicone over plastic capabilities.
