Rubber Seals
Customized Rubber Seals for your specific needs
Rubber Gaskets are essential sealing components used to create tight, leak-proof seals between two surfaces. Made from high-quality rubber materials, these gaskets are used in a wide variety of applications to prevent the leakage of fluids, gases, or contaminants, while also resisting temperature, chemical exposure, and wear.

Types of Rubber Seals
- O-Rings: Circular seals for preventing leaks in static and dynamic applications.
- Gaskets: Flat seals used to prevent leakage between two surfaces.
- Custom Seals: Tailored seals for unique shapes, sizes, and materials.
- Flat Seals & Washers: Used in flange connections to prevent fluid or gas leaks.
- Grommets & Bushings: Protect wires and pipes from abrasion and vibration.
Customized Rubber Seals: Tailored Solutions for Diverse Applications
- HVAC Systems: Seals for air conditioning units, refrigeration, and ventilation systems, ensuring airtight and leak-proof functionality.
- Automotive: Used in engines, transmissions, and brake systems, rubber seals prevent oil, fuel, and coolant leaks.
- Aerospace: Critical in aircraft sealing systems, where seals must withstand extreme conditions without failing.
- Food & Beverage: Seals used in manufacturing equipment where hygiene and contamination prevention are paramount.
- Oil & Gas: Rubber seals used in pumps, valves, and fluid transfer systems need to endure extreme pressures and harsh chemicals.

How to produce high-quality rubber molded products？
We're There Every Step of The Way
1. Material Selection
– Select the appropriate rubber compound based on the product’s requirements (e.g., hardness, flexibility, resistance).
– Mix and blend the rubber compound with additives, fillers, and curing agents to achieve the desired properties.
2. Mold Preparation:
– Design the mold according to the product’s specifications, including size, shape, and details.
– Fabricate the mold using materials such as metal or silicone, ensuring it’s precise and durable.
– Apply mold release agents to prevent sticking during the molding process.
3. Loading and Preforming:
– Place a measured amount of the prepared rubber material, known as a “charge,” into the mold cavity.
– Distribute the charge evenly to ensure uniformity in the final product’s shape and properties.
4. Compression Molding:
– Close the mold under controlled pressure to compress the rubber charge.
– Heat the mold to the curing temperature, causing the rubber to soften and flow to fill the mold cavity.
– Apply consistent pressure throughout the curing phase to achieve proper material distribution and reduce defects.
5. Curing:
– Maintain the mold at the curing temperature for a specified duration to facilitate cross-linking and vulcanization of the rubber.
– The curing time and temperature are determined by the rubber compound’s characteristics.
6. Cooling and Demolding:
– After curing, allow the mold to cool gradually to prevent thermal shock and maintain the final product’s dimensional stability.
– Open the mold and carefully remove the cured rubber product, known as the “green part.”
7. Trimming and Finishing:
– Trim excess flash or overflow material from the green part using tools or machinery.
– Perform additional finishing processes, such as buffing or grinding, to achieve the desired appearance and dimensions.
8. Quality Control and Testing:
– Inspect the finished product for defects, such as air pockets, voids, or surface imperfections.
– Conduct quality tests to ensure the product meets specifications, including hardness, tensile strength, and other relevant properties.
9. Packaging ：
– Design packaging that provides protection and fits the product’s dimensions.
– Use appropriate cushioning materials to prevent damage during transportation.
– Label packages with product information, barcodes, and handling instructions.
10.Transportation：
-Determine optimal transportation methods, routes, and carriers.
-Load packaged products onto transportation vehicles securely.
-Instruct handlers on proper handling techniques to prevent damage.
-Monitor shipments for adherence to delivery schedules.
-Ensure compliance with customs regulations for international shipments.
