From medical implants to aerospace seals, automotive sensors to consumer electronics, LSR overmolding enables the creation of complex, high-performance components that withstand extreme conditions while delivering flawless functionality. At Kinfomtech, we combine cutting-edge technology, meticulous craftsmanship, and competitive pricing to elevate your product quality and efficiency.

Why LSR Injection Molding? The Gold Standard for High-Performance Parts
LSR overmolding isn’t just a process—it’s a strategic advantage for manufacturers seeking unmatched versatility and reliability. Key benefits include:
– Extreme Temperature Resistance: Perform reliably in environments ranging from -60°C to 230°C (-76°F to 446°F).
– Chemical & Biological Inertness: Ideal for medical devices, food-grade applications, and harsh industrial settings.
– Flexibility & Durability: Maintain elasticity and tensile strength over millions of cycles.
– Seamless Encapsulation: Perfectly bond silicone to substrates (plastics, metals, electronics) for waterproof, shockproof designs.
– Eco-Friendly Production: Low waste, energy-efficient curing, and recyclable materials.

Our LSR Injection Molding Process: Precision in Every Step
From concept to finished product, our ISO-certified process ensures unmatched quality:

1. Mold Design & Manufacturing
– High-Hardness Steel Molds: CNC-machined to ±0.005mm tolerances for 500,000+ cycles.
– Overmolding Optimization: Design for substrates (e.g., PCB boards, metal inserts) to ensure perfect adhesion.

2. Material Preparation
– AB Glue Mixing: Precision blending of LSR A/B components for uniform viscosity and curing.
– Degassing & Filtration: Remove air bubbles and impurities to eliminate defects.

3. Injection Molding
– Cold-Runner Systems: Minimize material waste and cycle times.
– Precision Parameters: Control injection speed (0.1–1,000 cm³/s), pressure (up to 2,500 bar), and temperature (±1°C).

4. Curing & Demolding
– Platinum-Catalyzed Curing: Achieve FDA-compliant, odorless results in 10–30 seconds.
– Automated Demolding: Robotics ensure scratch-free extraction of delicate parts.

5. Post-Processing
– Laser Trimming: Remove flash with micron-level accuracy.
– Surface Finishing: Texturing, polishing, or plasma treatment for aesthetics and functionality.

Industries We Serve
– Medical: Silicone seals, respiratory masks, surgical tools (ISO 13485 compliant).
– Automotive: Gaskets, sensors, EV battery seals (IP67/IP68 rated).
– Electronics: Waterproof connectors, keypads, EMI shielding (UL94 V-0 certification).
– Consumer Goods: Baby products, kitchenware, wearables (FDA, LFGB compliant).
– Aerospace: Heat-resistant gaskets, vibration dampeners (MIL-SPEC standards).
