Top 10 Custom Liquid Silicone Rubber Manufacturers for Consumer Electronics

Choosing a Custom LSR Manufacturer for Consumer Electronics

Consumer electronics demand silicone parts that are thin, precise, and durable — from waterproof seals and buttons to overmolded connectors and wearable components. Choosing the right custom LSR manufacturer determines whether your parts meet tolerance, feel, and sealing requirements at scale.

Key Capabilities to Evaluate

LSR Injection Molding

Liquid silicone rubber injection molding is the standard for high-precision, high-volume electronics parts. Ask whether the manufacturer runs multi-cavity molds and can hold tight tolerances consistently across a production run.

Silicone Overmolding

Many electronics parts bond silicone to plastic, metal, or FPC (flexible printed circuit). Confirm the manufacturer has proven overmolding capability and can manage adhesion and sealing — for example IP67 or IP68 waterproof requirements.

Precision Silicone Parts

Wearables and connectors often need thin walls, fine details, and consistent shore hardness. Ask for sample parts and dimensional inspection data before committing tooling.

Questions to Ask a Potential Supplier

• Can you provide a DFM report before tooling?
• What is your sample lead time and mass-production lead time?
• Do you have experience with waterproof and overmolded electronics parts?
• Can you take a project from prototype through mass production?
