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.
