Liquid Silicone Injection Molding Silicone O-Rings

Overview:

Silicone O-rings excel in high-pressure sealing by deforming under compression, creating a robust barrier that prevents fluid leakage. Made from liquid silicone rubber using precision injection molding, these O-rings are available in durometers from 10 to 70 Shore A. This range ensures optimal control of elongation and softness, with 30 durometer O-rings offering balanced performance, and softer 10 and 20 durometer options providing flexibility. Customized for specific sealing needs, our O-rings ensure reliable and effective performance in various applications.

– Oxidation Resistance: Superior resistance to oxidation, ensuring long-term durability.

– Water Sealing: Excellent capability for sealing against water ingress.

– Softness Options: Available in soft grades, including 10, 20, and 30 durometer Shore A, for tailored flexibility and performance.

The Manufacturing Processes of Silicone O-Rings

  1. Material Preparation: Silicone rubber is formulated and compounded with various additives to achieve the desired properties, such as flexibility, hardness, and temperature resistance.
  2. Molding: The silicone rubber is either injected into a mold or compression-molded to form the basic shape of the O-ring. Liquid silicone injection molding is commonly used for precise and high-volume production, where the rubber is injected into a heated mold to cure and take shape.
  3. Curing: The molded O-rings are then cured in an oven at high temperatures. This process, known as vulcanization, cross-links the silicone polymers to enhance their strength, durability, and elasticity.
  4. Trimming: After curing, excess material or flash is removed from the O-rings to ensure they meet the specified dimensions and have a clean, finished appearance.
  5. Inspection: Each O-ring undergoes thorough inspection to check for defects, verify dimensions, and ensure the quality of the product. This includes testing for properties such as hardness, elasticity, and visual appearance.
  6. Packaging: The inspected O-rings are then packaged according to customer specifications and prepared for shipment. Packaging can include bulk packaging or individual packaging depending on the order requirements.
