SBT stands out as a leader in manufacturing custom O-rings, also referred to as packings or toric joints. An O-ring is a torus or doughnut-shaped gasket designed to effectively block the passage of liquids or gases. Crafted from elastomer materials, these circular cross-sectioned loops are strategically positioned within grooves to establish a tight seal. Normally, O-rings remain in the center of a gland until the pressure within the sealing system begins to escalate. At this point, the O-ring shifts away from the pressure and compresses to fill the gap between the two interconnected hardware components. O-rings prove invaluable in both static and dynamic applications, where they exhibit exceptional sealing capabilities.

Cost of Custom O-Ring Molds
The cost of custom O-ring molds can vary widely depending on several factors, including the complexity of the design, the material used, the size of the mold, and the manufacturing process. Additionally, the cost can also depend on the supplier and the quantity of molds ordered.
In general, the cost of a custom O-ring mold can range from a few hundred dollars to several thousand dollars. More complex molds with intricate designs or larger sizes will tend to be more expensive. The choice of material, such as silicone or rubber, can also affect the cost.
It's best to contact a O-Ring manufacturer or supplier to get a specific quote based on your requirements. We will typically ask for detailed specifications, such as the desired O-ring dimensions, material type, and any special features or tolerances. Providing this information will enable us to provide you with a more accurate cost estimate for your custom O-ring mold.
