Custom Molded & Die Cut Silicone Gaskets
Custom Molded & Die Cut Silicone Gaskets Supplier
Custom molded and die cut silicone gaskets are precision sealing components designed to prevent leakage, absorb vibration, and protect equipment from environmental contamination. These silicone rubber gaskets are manufactured to exact specifications so they fit perfectly between mating surfaces in machinery, equipment housings, and industrial systems.
At Suconvey, we manufacture custom silicone rubber gaskets using molding and die-cutting processes depending on the geometry, production volume, and performance requirements of the application.
Our custom silicone gaskets are widely used in industries such as electronics, medical devices, food processing, automotive systems, and industrial equipment.
Custom Molded & Die Cut Silicone Gaskets
A silicone gasket is a mechanical seal placed between two mating surfaces to prevent leakage of liquids, gases, or contaminants. When compressed, the gasket fills surface irregularities and maintains a tight seal between components.
Custom silicone gaskets can be manufactured through two primary methods:
Molded Silicone Gaskets
Molded gaskets are produced using compression or injection molding processes that form silicone rubber into complex three-dimensional shapes. Advantages include:
- precise geometry
- integrated sealing features
- strong structural integrity
- consistent material density
Molded gaskets are ideal for components with grooves, ribs, or complex sealing surfaces.
Die Cut Silicone Gaskets
Die cut silicone gaskets are produced by cutting shapes from silicone sheets using steel rule dies or CNC cutting equipment. This process provides high accuracy and repeatability for flat gasket designs. Die cutting is especially suitable for:
- flat gasket designs
- large production volumes
- cost-efficient manufacturing
- fast production cycles

Why Choose Silicone Rubber Gaskets
Silicone rubber is one of the most versatile elastomer materials used in industrial sealing applications. Key advantages include:
Wide Temperature Resistance
Silicone rubber can maintain flexibility and sealing performance across a broad temperature range, making it suitable for both high-temperature and low-temperature applications.
Long-Term Durability
Silicone resists aging, ozone exposure, UV radiation, and environmental degradation, which allows the gasket to maintain sealing performance over long service periods.
Excellent Flexibility & Compression Recovery
When compressed between surfaces, silicone rubber maintains elasticity and returns to its original shape, ensuring reliable sealing over repeated compression cycles.
Chemical Resistance
Silicone materials resist many industrial chemicals, moisture, and environmental contaminants.

Packaging & Shipping Information
To protect the product during global transportation and storage, we apply export-grade packaging and provide flexible shipping solutions.
Pre-Shipment Inspection
Each batch is inspected before packaging to confirm hardness, thickness, surface condition, and visual uniformity. Batch codes are recorded and compliance documentation may be provided when required for regulatory purposes.
Packaging Method
Silicone gaskets are wrapped with protective film to prevent dust, moisture, and surface damage. Several rolls are placed into reinforced cartons, which are then secured on fumigation-free pallets using straps and stretch film.
Shipment Options
We regularly ship to customers in Europe, North America, and Asia through sea freight, air freight, or express courier for urgent testing needs. Both FCL and LCL shipments are available.
Documentation Support
All necessary export documents can be provided for customs clearance, including commercial invoice, packing list, bill of lading or airway bill, certificate of origin, and food-contact compliance statements or test reports when applicable.
Sample Delivery
Material samples and short test gaskets can be supplied for validation and equipment trials. Samples can be sent via DHL, FedEx, UPS, TNT, or using your appointed courier account.
