Applications of Plastic Multiflex Chains

1. Conveyor Systems

Plastic multiflex chains are commonly used in conveyor systems to transport goods efficiently and reliably. Their flexibility allows them to navigate complex layouts, including inclines and declines.

2. Manufacturing and Assembly Lines

In manufacturing and assembly lines, plastic multiflex chains facilitate the smooth flow of products between workstations. Their flexibility and low maintenance make them an ideal choice for optimizing production processes.

3. Distribution and Warehousing

Plastic multiflex chains play a crucial role in distribution and warehousing by efficiently moving goods along conveyor belts and sorting systems. They enable quick and accurate order fulfillment.

4. Packaging and Bottling

Plastic multiflex chains are widely used in packaging and bottling industries, ensuring the seamless transfer of products through filling, capping, labeling, and packaging processes.

5. Material Sorting and Grading

Plastic multiflex chains are employed in material sorting and grading systems, enabling the automated segregation and categorization of products based on their attributes or quality.

6. Cleanroom Environments

Due to their cleanability and hygienic properties, plastic multiflex chains are commonly utilized in cleanroom environments where maintaining a controlled and sterile atmosphere is crucial.

Working Principles 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 maximum weight that the chain needs to support to ensure it can handle the intended load without deformation or failure.

2. Application Environment

Evaluate the operating conditions, such as temperature, moisture, chemicals, and cleanliness requirements, to select a chain that can withstand the specific environment.

3. Chain Material

Choose the appropriate chain material based on the application requirements, considering factors such as chemical resistance, wear resistance, and durability.

4. Chain Profile and Design

Select the chain profile and design that aligns with the conveying system’s layout and requirements. Different profiles offer varying levels of flexibility and load-bearing capacity.

5. Environmental Factors

Consider any external factors, such as UV exposure or extreme temperatures, that might affect the chain’s performance and select a chain that is suitable for such conditions.

6. Conveyor System Layout

Take into account the conveyor system’s layout and configuration to ensure proper chain engagement and smooth operation throughout the entire system.

7. Maintenance and Cleanability

Choose a chain that is easy to clean and maintain, minimizing downtime and ensuring optimal performance over time.

8. Cost Considerations

Evaluate the overall cost-effectiveness of the chain, considering factors such as initial investment, maintenance costs, and expected lifespan.

9. Supplier and Support

Consider the reputation and expertise of the chain supplier, as well as the availability of technical support and after-sales service.

Multiflex Chain Advantages

Installation and Maintenance of Plastic Multiflex Chains


1. Preparatory Steps

Prior to installation, ensure that the conveyor system and supporting structures are prepared, including proper alignment and adjustment.

2. Chain Assembly

Assemble the plastic multiflex chain by interlocking the modules and securing them with the necessary fasteners, following the manufacturer’s instructions.

3. Sprocket Installation

Install the sprockets or sprocket wheels onto the conveyor system, ensuring proper alignment with the chain and secure attachment.

4. Tracking Adjustment

Adjust the chain tracking by fine-tuning the sprocket position and tension, ensuring smooth and centered movement along the conveyor path.


1. Regular Cleaning

Regularly clean the plastic multiflex chain to remove any dirt, debris, or buildup that may affect its performance. Use appropriate cleaning agents and methods recommended by the manufacturer.

2. Inspection

Periodically inspect the chain for any signs of wear, damage, or misalignment. Address any issues immediately to prevent further damage and ensure continued smooth operation.

3. Lubrication

Apply lubrication, if recommended by the manufacturer, to the chain components to reduce friction and extend their lifespan. Use lubricants compatible with the chain material.

4. Repair and Replacement

Repair or replace damaged or worn-out chain modules, fasteners, or sprockets promptly to maintain the chain’s integrity and prevent disruptions in the conveyor system.

5. Training and Documentation

Provide training to personnel responsible for chain maintenance, emphasizing proper cleaning techniques, inspection procedures, and safety precautions. Keep detailed documentation of maintenance activities for reference and future audits.

Sprockets: An Essential Component for Plastic Multiflex Chains


Sprockets play a crucial role in the operation of plastic multiflex chains. They are designed to engage with the tabs or hinges on the chain modules, driving the chain forward and facilitating its articulation.

The accurate alignment and engagement between sprockets and plastic multiflex chains ensure smooth and synchronized movement, preventing chain misalignment or jamming. Sprockets are engineered to withstand the load and provide reliable power transmission while minimizing friction and wear.

Matching the right sprockets with plastic multiflex chains is essential to ensure optimal performance and longevity of the conveying system. Proper selection considers factors such as chain pitch, tooth profile, material compatibility, and load capacity. Working in tandem, sprockets and plastic multiflex chains form a dynamic and efficient power transmission system.
