8. Energy Efficiency

Thanks to their low friction and efficient power transmission, these chains contribute to energy savings and reduced operating costs.

9. Versatility

Plastic multiflex chains can be customized and adapted to various conveyor layouts and configurations, allowing for versatile and efficient material handling solutions.

Multiflex Chain Application

Applications of Plastic Multiflex Chains

1. Conveyor Systems

Plastic multiflex chains are commonly used in conveyor systems for industries such as manufacturing, packaging, and distribution. They provide reliable and efficient transportation of goods and materials.

2. Manufacturing and Assembly Lines

These chains are suitable for manufacturing and assembly lines, facilitating the movement of products during production processes and ensuring smooth operations.

3. Distribution and Warehousing

In distribution centers and warehouses, plastic multiflex chains enable the efficient sorting, storage, and transportation of goods, optimizing logistics operations.

4. Packaging and Bottling

In packaging and bottling plants, these chains ensure smooth and precise movement of packaged products, allowing for accurate and high-speed packaging operations.

5. Material Sorting and Grading

Plastic multiflex chains are utilized in material sorting and grading systems, enabling the separation and classification of different materials based on size, shape, or quality.

6. Cleanroom Environments

These chains are suitable for cleanroom environments, including industries such as electronics, pharmaceuticals, and semiconductors, where cleanliness and contamination control are critical.

Multiflex Chains Application

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 maximum load that the chain will be subjected to and ensure that it can handle the weight without compromising performance or safety.

2. Application Environment

Assess the environmental conditions, such as temperature, humidity, and exposure to chemicals, to select a chain with the appropriate material and resistance properties.

3. Chain Material

Choose a chain material that meets the specific requirements of the application, considering factors such as strength, wear resistance, and chemical compatibility.

4. Chain Profile and Design

Select a chain profile and design that aligns with the conveyor system layout and the type of products or materials being conveyed.

5. Environmental Factors

Take into account external factors, such as dust, debris, and potential contaminants, and choose a chain that can withstand and resist these elements.

6. Conveyor System Layout

Analyze the conveyor system layout and configuration to determine the appropriate chain size, length, and connection methods for optimal performance.

7. Maintenance and Cleanability

Consider the ease of maintenance and cleanability of the chain, ensuring that it can be readily cleaned, inspected, and maintained to prolong its lifespan and performance.

8. Cost Considerations

Evaluate the cost-effectiveness of the chain, taking into account factors such as initial investment, operational costs, and expected lifespan.

9. Supplier and Support

Choose a reputable supplier that can provide technical support, customization options, and reliable after-sales service to ensure a successful implementation.

Multiflex Chain Advantages

Installation and Maintenance of Plastic Multiflex Chains


1. Preparatory Steps

Prior to installation, ensure that all necessary tools and equipment are available. Clear the installation area and prepare the conveyor system for chain installation.

2. Chain Assembly

Assemble the plastic multiflex chain by interlocking the modules and securing them with the appropriate connectors or pins.

3. Sprocket Installation

Install the sprockets onto the drive and idler shafts, ensuring proper alignment and engagement with the chain modules.

4. Tracking Adjustment

Adjust the tracking of the chain by aligning the sprockets and adjusting the tension or position of the chain as necessary to ensure smooth and centered movement.


1. Regular Cleaning

Regularly clean the chain and remove any debris or contaminants that may accumulate on the surface or within the chain modules.

2. Inspection

Periodically inspect the chain for wear, damage, or signs of misalignment. Replace any worn or damaged modules or connectors promptly.

3. Lubrication

Apply appropriate lubrication to the chain and sprockets to reduce friction and ensure smooth movement. Follow the manufacturer’s recommendations for lubricant type and frequency of application.

4. Repair and Replacement

If any components of the chain are damaged beyond repair or show signs of excessive wear, replace them with new ones to maintain optimal performance and safety.

5. Training and Documentation

Provide training to operators and maintenance personnel on proper chain handling, maintenance procedures, and safety protocols. Maintain documentation of maintenance activities for reference and future audits.
