The pad is formed as an integrated silicone component, with each section contributing to the contact and vacuum-holding function. The geometry can be adjusted around the product surface or mounting position.
- Vacuum Cavity - Creates the enclosed space where air is displaced during application.
- Sealing Lip - Forms the primary contact edge around the cavity and supports the pressure difference.
- Flexible Pad Body - Allows controlled deformation when the pad is pressed against the target surface.
- Mounting Section - Can be integrated with a base, holder, or product interface according to the assembly design.
The holding effect is generated through the interaction between the flexible silicone body and the contact surface rather than through an adhesive layer.
- Surface Contact - Pressing the pad against the surface reduces the air volume inside the cavity.
- Air Displacement - The flexible body deforms to push air toward the cavity edge.
- Pressure Difference - Once the cavity is sufficiently enclosed, the pressure difference helps maintain attachment.
- Release - Lifting or peeling the sealing edge allows air to enter and breaks the vacuum for removal.
Silicone Vacuum Suction Pad Material Performance
Stable Elastic Recovery
The silicone pad can recover its original geometry after controlled compression and release. This helps maintain the designed cavity profile and contact geometry over repeated operating cycles.
Low Permanent Deformation
The silicone formulation and molded geometry can be selected to limit permanent set under the specified compression conditions. This helps the pad retain its designed profile after extended use.
Dimensional Consistency
Controlled molding parameters help maintain critical features such as cavity geometry, sealing-edge profile, and mounting dimensions from batch to batch. Consistent geometry supports predictable assembly and product performance.

Product Interface - Mounting bases, connection sections, or integrated positioning features can be incorporated into the design.
Material & Hardness - Silicone compound and Shore A hardness can be selected according to deformation, contact, and operating requirements.
Sample to Production - Supports prototype development, mold preparation, sample approval, and subsequent batch manufacturing.
FAQ
Can the vacuum pad be integrated into a finished food container or product?
Yes. The pad can be designed with a suitable mounting interface for integration into the customer's product structure.
Can the vacuum pad be supplied in different shapes?
Yes. Round, oval, rectangular, and application-specific profiles can be developed when the product structure requires a different contact geometry.
Can the vacuum pad be used with an automatic assembly process?
Potentially. The pad geometry can be reviewed according to the customer's feeding, positioning, and assembly method to avoid interference during automated installation.
