Description
Product Description
In modern 3C consumer electronic products, battery protection has become a critical factor affecting product reliability, safety, and service life. The waterproof silicone encapsulation battery cover is a high-performance sealing solution designed to protect battery modules from moisture, dust, vibration, and environmental stress.
At siliconeplus.net, we specialize in custom silicone overmolding and encapsulation solutions for electronic components, providing OEM and ODM services tailored to global consumer electronics brands.
Why Silicone Encapsulation for Battery Covers?
Compared with traditional gaskets, adhesives, or mechanical sealing structures, silicone encapsulation offers a seamless and highly reliable protective layer around the battery cover.
Key advantages include:
Excellent waterproof and dustproof performance
Long-term elasticity without cracking or shrinkage
Strong adhesion to plastic or metal substrates
Resistance to temperature changes, chemicals, and aging
Stable sealing under vibration and mechanical stress
High-Precision Silicone Overmolding Process
Our battery covers are manufactured using LSR (Liquid Silicone Rubber) injection overmolding, ensuring high dimensional accuracy and consistent quality across mass production.
The process integrates silicone directly onto the battery housing, creating a one-piece waterproof structure that eliminates assembly gaps and reduces failure points.
Process highlights:
Automated injection molding for high repeatability
Controlled curing for stable mechanical properties
Optional secondary bonding or surface treatments
Suitable for complex geometries and thin-wall designs
