Plastic multiflex chains are lightweight, reducing the overall weight of the conveyor system and allowing for easier handling and installation. Their low weight also contributes to energy efficiency.

2. Flexibility

Plastic multiflex chains offer excellent flexibility, allowing them to adapt to various conveyor layouts and configurations. This flexibility enables smooth product flow and reduces the risk of jams or blockages.

3. High Strength

Despite their lightweight nature, plastic multiflex chains are engineered to provide high strength and durability. They can withstand heavy loads and resist wear and tear, ensuring reliable performance in demanding applications.

4. Low Maintenance

Due to their durable construction and self-lubricating properties, plastic multiflex chains require minimal maintenance. This reduces downtime and maintenance costs, making them a cost-effective choice for businesses.

5. Noise Reduction

Plastic multiflex chains produce less noise compared to traditional conveyor chains, contributing to a quieter and more comfortable working environment.

6. Chemical Resistance

Plastic multiflex chains are resistant to a wide range of chemicals, including oils, solvents, and acids. This makes them suitable for applications where exposure to corrosive substances is a concern.

7. Cleanliness and Hygiene

Plastic multiflex chains are easy to clean and maintain sanitary conditions. They are resistant to bacterial growth and can be washed or sterilized, making them ideal for industries with strict hygiene requirements.

8. Energy Efficiency

The lightweight and low-friction properties of plastic multiflex chains contribute to energy savings and reduced power consumption in conveyor systems.

9. Versatility

Plastic multiflex chains can be customized and adapted to suit various applications and industries. They are compatible with different conveyor types and can be easily integrated into existing systems.

Applications of Plastic Multiflex Chains

1. Conveyor Systems

Plastic multiflex chains are widely used in conveyor systems for industries such as food processing, packaging, and recycling. They ensure smooth and efficient material handling, enhancing productivity.

2. Manufacturing and Assembly Lines

In manufacturing and assembly processes, plastic multiflex chains facilitate the movement of products or components along the production line, enabling seamless operations and reducing manual handling.

3. Distribution and Warehousing

Plastic multiflex chains are employed in distribution and warehousing facilities to transport goods within the warehouse or distribution center. They enable efficient sorting, storage, and retrieval of products.

4. Packaging and Bottling

Plastic multiflex chains play a crucial role in packaging and bottling lines, ensuring the smooth transfer and positioning of containers, cartons, and bottles. They contribute to high-speed and accurate packaging operations.

5. Material Sorting and Grading

Plastic multiflex chains are utilized in material sorting and grading systems, allowing for precise separation and classification of different materials based on size, weight, or other criteria.

6. Cleanroom Environments

In cleanroom environments, where maintaining cleanliness and preventing contamination is crucial, plastic multiflex chains provide hygienic and reliable conveying solutions.

Working Principle of Plastic Multiflex Chains

Plastic multiflex chains operate on the principle of interlocking modular units. The chain consists of individual plastic links or modules that are interconnected to form a continuous chain loop. Each module has built-in tabs or hinges that allow it to flex and articulate, providing flexibility in various directions.

The chain is driven by sprockets or sprocket wheels, which engage with the tabs on the modules and propel the chain forward. The modular design allows for easy assembly, disassembly, and customization of the chain to suit specific conveyor layouts and requirements.

As the sprockets rotate, they engage with the modules, causing them to articulate and move along the conveyor path. The interlocking design ensures smooth and synchronized movement of the chain, allowing for the efficient transfer of products or materials from one point to another.

Choosing the Right Plastic Multiflex Chains

1. Load Capacity

Consider the weight and load requirements of your application to ensure the plastic multiflex chains can handle the intended loads without compromising performance.

2. Application Environment

Evaluate the operating conditions, such as temperature, humidity, and exposure to chemicals or abrasive materials, to select chains with appropriate resistance and durability.

3. Chain Material

Choose the right material, such as polyethylene (PE) or polypropylene (PP), based on the specific requirements of your application. Each material offers distinct properties and characteristics.

4. Chain Profile and Design

Select the chain profile and design that best suits your conveyor system layout and product handling needs. Options include straight-running, side-flexing, and modular chains.

5. Environmental Factors

Consider any environmental regulations or requirements that may impact your choice of plastic multiflex chains, such as food-grade certifications for the food processing industry.

6. Conveyor System Layout

Analyze the layout and configuration of your conveyor system to determine the appropriate chain length, width, and number of modules needed for seamless operation.

7. Maintenance and Cleanability

Choose plastic multiflex chains that are easy to clean and maintain, ensuring efficient operation and minimizing downtime. Look for chains with smooth surfaces and self-lubricating properties.

8. Cost Considerations

Balance the upfront costs with the long-term benefits and durability of the plastic multiflex chains. Consider the total cost of ownership, including maintenance and potential downtime costs.

9. Supplier and Support

Select a reputable supplier that provides reliable support, technical assistance, and after-sales services to ensure a smooth implementation and ongoing performance of the plastic multiflex chains.

Installation and Maintenance of Plastic Multiflex Chains


1. Preparatory Steps

Before installing the plastic multiflex chains, ensure the conveyor system is properly prepared, including aligning the tracks and ensuring the correct tension and alignment of the sprockets.

2. Chain Assembly

Connect the individual plastic modules to form a continuous chain loop. Follow the manufacturer’s instructions for proper assembly, ensuring the tabs or hinges are securely engaged.

3. Sprocket Installation

Install the sprockets or sprocket wheels at the designated positions, ensuring they engage properly with the tabs on the modules. Adjust the sprockets as necessary to ensure smooth chain movement.

4. Tracking Adjustment

Carefully adjust the tracking of the plastic multiflex chains to ensure they stay aligned and centered on the conveyor system. Regularly check and readjust the tracking as needed to maintain optimal performance.


1. Regular Cleaning

Clean the plastic multiflex chains regularly to remove any debris, dust, or contaminants that may affect their performance. Use suitable cleaning agents and methods recommended by the manufacturer.

2. Inspection

Periodically inspect the chains for signs of wear, damage, or misalignment. Replace any worn or damaged modules or components to maintain optimal performance and prevent potential breakdowns.

3. Lubrication

Apply lubrication to the chain and sprockets as recommended by the manufacturer. Proper lubrication reduces friction, enhances chain movement, and prolongs the lifespan of the plastic multiflex chains.

4. Repair and Replacement

Address any issues promptly by repairing or replacing damaged modules, components, or sprockets. Regularly monitor the condition of the chains and take corrective actions as necessary.

5. Training and Documentation

Train personnel on proper maintenance procedures and provide them with documentation and guidelines for reference. Ensure they understand the importance of regular maintenance and follow the recommended practices.
