Plastic multiflex chains require minimal maintenance compared to traditional metal chains. Their self-lubricating properties and resistance to corrosion and wear ensure prolonged service life with reduced downtime.

5. Noise Reduction

Plastic multiflex chains produce less noise during operation due to their inherent vibration-damping characteristics. This feature contributes to a quieter working environment and improved worker comfort.

6. Chemical Resistance

Plastic multiflex chains exhibit excellent chemical resistance, making them suitable for aggressive chemical environments. They can withstand exposure to various acids, alkalis, solvents, and other corrosive substances without compromising their structural integrity.

7. Cleanliness and Hygiene

Plastic multiflex chains are easy to clean and maintain high levels of cleanliness. They are resistant to bacterial growth, making them ideal for industries with strict hygiene requirements, such as food and pharmaceutical manufacturing.

8. Energy Efficiency

The lightweight design of plastic multiflex chains reduces energy consumption during operation. This energy efficiency contributes to cost savings and environmental sustainability.

9. Versatility

Plastic multiflex chains can be customized to meet specific application requirements. They are available in various sizes, configurations, and materials, allowing for compatibility with different conveyor systems and product types.

Applications of Plastic Multiflex Chains

1. Conveyor Systems

Plastic multiflex chains are widely used in conveyor systems, enabling the efficient movement of products along production lines or distribution centers. They provide reliable and smooth conveying, reducing the risk of product damage or jams.

2. Manufacturing and Assembly Lines

Plastic multiflex chains play a crucial role in manufacturing and assembly lines, facilitating the movement of components or products during the production process. Their flexibility and strength ensure seamless operations.

3. Distribution and Warehousing

In distribution and warehousing facilities, plastic multiflex chains enable the smooth transportation of goods within the facility. Their durability and low maintenance requirements make them suitable for handling heavy loads and operating in a demanding environment.

4. Packaging and Bottling

Plastic multiflex chains are commonly used in packaging and bottling industries to transport containers, packages, or bottles. Their flexibility and precise control contribute to efficient packaging operations.

5. Material Sorting and Grading

Plastic multiflex chains are utilized in material sorting and grading systems, ensuring accurate and efficient separation or classification of different materials based on their characteristics or sizes.

6. Cleanroom Environments

In cleanroom environments, where strict cleanliness and hygiene are essential, plastic multiflex chains provide a hygienic solution. They are resistant to contamination and can be easily cleaned, making them suitable for industries such as pharmaceuticals, electronics, and healthcare.

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.

How to Select Suitable Plastic Multiflex Chains

1. Load Capacity

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

2. Application Environment

Evaluate the operating environment, including temperature extremes, exposure to chemicals or moisture, and any unique conditions that may affect the performance of the chain.

3. Chain Material

Choose the appropriate chain material, such as polyethylene (PE) or polypropylene (PP), based on the application requirements and the compatibility with the conveyed products.

4. Chain Profile and Design

Select the chain profile and design that best suits the specific application, considering factors such as required conveying speed, product shape, and potential interactions with other components.

5. Environmental Factors

Take into account any environmental factors, such as dust, humidity, or corrosive substances, that may impact the performance and lifespan of the plastic multiflex chain.

6. Conveyor System Layout

Analyze the conveyor system layout and configuration to ensure the plastic multiflex chain can be properly integrated and optimized for efficient product movement.

7. Maintenance and Cleanability

Consider the ease of maintenance and cleanability of the plastic multiflex chain, as regular cleaning and lubrication are necessary to ensure optimal performance and longevity.

8. Cost Considerations

Evaluate the overall cost-effectiveness of the plastic multiflex chain, taking into account factors such as initial investment, maintenance costs, and potential savings in energy consumption or product loss.

9. Supplier and Support

Choose a reputable supplier with a track record of providing high-quality plastic multiflex chains and reliable customer support to ensure the availability of technical assistance and spare parts.

Installation and Maintenance of Plastic Multiflex Chains


1. Preparatory Steps: Prepare the conveyor system, ensuring proper alignment and clearance for the installation of the plastic multiflex chain.

2. Chain Assembly: Connect the individual plastic links or modules to form a continuous chain loop, following the manufacturer’s instructions for proper assembly.

3. Sprocket Installation: Install the sprockets or sprocket wheels at the appropriate locations, ensuring proper engagement with the tabs or hinges on the plastic modules.

4. Tracking Adjustment: Adjust the tracking of the plastic multiflex chain to ensure smooth and consistent movement along the conveyor path, making any necessary adjustments to the sprocket positions or tensioning mechanisms.


1. Regular Cleaning: Clean the plastic multiflex chain regularly to remove any debris, dust, or contaminants that may accumulate on the chain surface or within the interlocking modules.

2. Inspection: Conduct periodic inspections to check for any signs of wear, damage, or misalignment. Address any issues promptly to prevent further damage or disruption to the conveyor system.

3. Lubrication: Apply lubrication as recommended by the chain manufacturer to ensure smooth articulation and minimize friction between the plastic modules and the sprockets.

4. Repair and Replacement: Replace any worn or damaged plastic modules or sprockets to maintain the integrity and performance of the plastic multiflex chain. Follow the manufacturer’s guidelines for replacement parts.

5. Training and Documentation: Provide training to operators and maintenance personnel on proper handling, installation, and maintenance of the plastic multiflex chain. Keep detailed documentation of maintenance activities and any modifications made to the chain system.

Sprockets and their Importance

In conjunction with plastic multiflex chains, sprockets play a vital role in the efficient operation of conveying systems. Sprockets are toothed wheels with specially designed grooves that engage with the tabs or hinges on the plastic modules, propelling the chain forward and ensuring synchronized movement. The correct selection and installation of sprockets are essential for maintaining smooth and reliable chain performance, minimizing wear, and maximizing the lifespan of the conveyor system.
