Material Mixing Process – Compounding

Compounding is the first and most important step in creating high-quality rubber products. This is the stage where rubber (natural or synthetic) is mixed with additives, vulcanizing agents, and reinforcing components to optimize material properties.

Main components in compounding:

• Base rubber: natural rubber, EPDM, NBR, Neoprene, Silicone, Viton, etc.
• Vulcanizing agents: sulfur or peroxide.
• Reinforcing agents: carbon black, silica.
• Plasticizers: increase softness and flexibility.
• Antioxidants and anti-aging agents.

Why is compounding important?

• Determines hardness (Shore A), tensile strength, and compression resistance.
• Creates oil, chemical, and ozone resistance capabilities.
• Stabilizes the quality of rubber products over long periods.

Benefits for businesses:

• Rubber products meet technical durability standards.
• Reduce product defects and increase component lifespan.
• Optimize production costs through quality control from the start.

The compounding stage is essentially the “soul” that creates durable, stable rubber products suitable for each industrial requirement.

Rubber Product Forming Process

Molding – Compression Molding

Molding is the most important method for creating rubber products with complex shapes and high precision. In industry, most products such as o-rings, gaskets, bushings, machine mounts, seals, and grommets are created through molding.

Common molding types:

• Compression molding: used for thick products with few details.
• Transfer molding: suitable for products requiring high precision.
• Injection molding: fast production – precise – large quantities.

Advantages of producing rubber products through molding:

• Stable forming with low error rates.
• Beautiful and uniform surface.
• Suitable for products with complex structures.
• Reduces material waste, optimizes costs.

Molding applications in rubber product manufacturing:

• Vibration damping components and machine mounts.
• Oil-resistant and chemical-resistant rubber gaskets.
• Technical rubber components in automotive and mechanical industries.

Thanks to its precise forming capabilities, molding is considered the core solution for producing high-quality rubber products across many industries.

Extrusion – Rubber Extrusion

Extrusion is suitable for producing long, continuous rubber products with uniform cross-sections. This is a commonly used process for door gaskets, refrigerator gaskets, rubber hoses, U/V/H-shaped seals, and technical rubber profiles.

Main extrusion process steps:

• Extrude rubber through a forming die.
• Cool the product.
• Continuous vulcanization using steam/hot air.
• Cut to required dimensions.

Advantages of rubber products manufactured by extrusion:

• Continuous forming with high productivity.
• Lower cost than molding.
• Easy to customize cross-sections as needed.

Notable applications:

• Automotive door gaskets – aluminum and glass door gaskets.
• Air hoses – water hoses.
• Rubber cushions for impact protection.

Extrusion helps rubber products achieve dimensional accuracy and provides high efficiency for applications requiring long lengths and stable shapes.

Vulcanization

Vulcanization is the step that determines the durability, elasticity, and lifespan of rubber products. Without vulcanization, rubber will be soft, easily torn, and unable to bear loads.

Common vulcanization technologies:

• Sulfur vulcanization: used for natural rubber – EPDM – NBR.
• Peroxide vulcanization: increases heat resistance.
• Vulcanization by steam – hot air oven – microwave.

Important effects of vulcanization:

• Increases tensile strength and hardness.
• Enhances heat and environmental resistance.
• Stabilizes rubber product shape.
• Reduces flow and deformation phenomena.

Why is this a critical step?

• Rubber products only achieve standard quality when vulcanized with correct parameters.
• Small deviations in time or temperature can ruin an entire production batch.

Vulcanization ensures rubber products have long-term durability, meeting stringent requirements in heavy industry and environments with continuous load bearing.
