What Is Silicone/LSR Injection Molding?
Silicone/LSR (Liquid Silicone Rubber) injection molding is a manufacturing process used to produce parts and components from silicone or LSR materials. It is a highly versatile and efficient method for creating complex, precise, and durable silicone products. The process involves injecting liquid silicone rubber into a mold cavity, where it is cured to form the desired shape.
Key Features and Steps of Silicone/LSR Injection Molding Include:
- Material Preparation
- Injection
- Curing
- Demolding
- Post-processing (if necessary)
Applications of Silicone/LSR Injection Molding
- Medical: Silicone/LSR molding for medical equipment like seals, catheters, and high-temperature-resistant components due to biocompatibility and chemical resistance.
- Automotive: Used in vehicles for seals, mud flaps, thermal pads, connectors, and exhaust parts, thanks to high-temperature and aging resistance.
- Electronics: Ideal for sealing, insulating, and waterproofing electronic devices such as smartphone cases, connectors, and gaskets.
- Consumer Goods: Employed in consumer products like kitchen utensils, baby bottle nipples, watch straps, and swim goggles due to durability and water resistance.
- Industrial: Used in industrial settings for sealing rings, gaskets, vibration dampers, valve components, and more.
- Food and Beverage: Compliant with food safety standards for food-grade seals, molds, oven gaskets, etc.
- Aerospace: Used in aerospace for high-temperature seals, vibration dampers, spacecraft seals, and fuel system components.
- Construction: Applied in building and construction for seals, insulation gaskets, and waterproof coating materials.
