Rubber sheets are used in a wide range of industries. From industrial environments to consumer products, it can be found everywhere. Have you ever wondered how these basic components are made? Today, orientflex rubber sheet manufacturers will take you through the process of making rubber sheets. From the selection of the right material to the final production stage.

How to make rubber sheet

Material Selection

1.1. Raw Rubber:
Choose the appropriate type of raw rubber based on the desired properties of the final rubber sheet. Common types include natural rubber, synthetic rubber, or a blend of both.
1.2. Additives:
Determine the required additives, such as curing agents, accelerators, fillers, and pigments, based on the desired characteristics and application of the rubber sheet.

Mixing Process

2.1. Weighing and Preparing the Ingredients:
Accurately measure and weigh the raw rubber, additives, and other ingredients according to the specific recipe or formulation.
2.2. Mixing:
Introduce the raw rubber and additives into a mixing machine, such as a two-roll mill or an internal mixer.
Ensure thorough blending of the materials to achieve a homogenous mixture.
2.3. Heating and Cooling:
Heat the mixture to the appropriate temperature to facilitate the mixing process and improve the flow characteristics of the rubber compound.
Followed by cooling to prevent premature curing or damage to the material.


3.1. Preparing the Calendering Machine:
Set up the calendering machine by adjusting the rolls, ensuring the desired gap between them.
3.2. Feeding the Rubber Compound:
Feed the mixed rubber compound into the calendering machine, ensuring consistent and uniform distribution.
3.3. Calendering Process:
Pass the rubber compound through the rolls of the calendering machine, which apply heat, pressure, and controlled friction.
Adjust the temperature and speed to achieve the desired thickness and smoothness of the rubber sheet.
3.4. Cooling and Trimming:
Allow the rubber sheet to cool after calendering to stabilize its shape and properties.
Trim the edges of the rubber sheet to achieve the desired dimensions.


4.1. Preparing the Curing Process:
Determine the appropriate curing method based on the type of rubber compound and desired properties.
Options include vulcanization using heat, chemical curing agents, or radiation curing processes.
4.2. Curing Temperature and Time:
Set the curing temperature and time according to the specifications of the rubber compound and the desired level of cross-linking.
4.3. Curing Process:
Place the rubber sheet in a curing press, oven, or other curing equipment.
Apply the necessary temperature and pressure for the specified duration to facilitate cross-linking and achieve the desired physical and chemical properties.

Finishing and Quality Control

5.1. Surface Treatment:
Apply surface treatments, such as coatings, embossing, or texturing, to enhance the appearance, grip, or performance characteristics of the rubber sheet.
5.2. Quality Control:
Conduct thorough quality control checks throughout the production process to ensure the rubber sheet meets the required specifications.
Inspect for any defects, inconsistencies, or imperfections that could impact the performance or appearance of the final product.

Packaging and Distribution

6.1. Packaging:
Package the finished rubber sheets in appropriate containers or
wrappings to protect them from damage during transportation and storage.
6.2. Distribution:
Arrange for the distribution of the rubber sheets to customers, retailers, or other end-users based on their specific requirements.

Continuous Improvement and Innovation

7.1. Feedback and Evaluation:
Gather feedback from customers and end-users to understand their needs and identify areas for improvement in the manufacturing process.
7.2. Research and Development:
Invest in research and development activities to explore new materials, additives, and manufacturing techniques that can enhance the quality, performance, and sustainability of rubber sheets.
7.3. Environmental Considerations:
Emphasize sustainable practices by optimizing energy consumption, reducing waste generation, and exploring eco-friendly alternatives in the manufacturing process.

Manufacturing high-quality rubber sheets requires careful attention to detail, precise formulation and expertise in the manufacturing process. From selecting the right material to calendering, curing and finishing, each step contributes to the performance and properties of the final product. orientflex has been manufacturing rubber sheets for many years and has the experience to guarantee product quality and customize them to meet customer needs.
