Plastic Multiflex Chains for Precise Indexing Systems

In the realm of material handling and power transmission, plastic multiflex chains have emerged as a versatile and effective solution for conveying a wide range of products and materials.

These chains, constructed from durable thermoplastic materials such as polyethylene (PE) or polypropylene (PP), offer a compelling combination of flexibility, strength, and low maintenance, making them well-suited for diverse applications.

Advantages of Plastic Multiflex Chains

1. Lightweight

Plastic multiflex chains are significantly lighter than traditional metal chains, allowing for easier installation and reducing energy consumption.

2. Flexibility

The modular design of plastic multiflex chains allows them to flex and articulate in multiple directions, enabling smooth product transfer and adaptability to various conveyor layouts.

3. High Strength

Despite their lightweight nature, plastic multiflex chains exhibit exceptional strength and load-bearing capacity, ensuring reliable and efficient operation.

4. Low Maintenance

Plastic multiflex chains require minimal maintenance due to their self-lubricating properties and resistance to wear and corrosion, resulting in reduced downtime and cost savings.

5. Noise Reduction

The use of plastic materials helps to reduce noise generated during operation, creating a quieter and more comfortable working environment.

6. Chemical Resistance

Plastic multiflex chains are resistant to a wide range of chemicals, making them suitable for applications involving exposure to corrosive substances.

7. Cleanliness and Hygiene

These chains are easy to clean and maintain sanitary conditions, making them ideal for industries with strict hygiene requirements, such as food and pharmaceuticals.

8. Energy Efficiency

Due to their lightweight and low friction properties, plastic multiflex chains minimize energy consumption, contributing to overall energy efficiency.

9. Versatility

Plastic multiflex chains can be customized to suit various applications and can be easily integrated into existing conveyor systems.


1. Conveyor Systems

Plastic multiflex chains are widely used in conveyor systems for industries such as manufacturing, logistics, and e-commerce, facilitating efficient product transportation.

2. Manufacturing and Assembly Lines

These chains play a crucial role in manufacturing and assembly lines, ensuring smooth movement of components and products during production processes.

3. Distribution and Warehousing

Plastic multiflex chains are utilized in distribution and warehousing applications, enabling the quick and reliable transfer of goods and materials.

4. Packaging and Bottling

These chains are employed in packaging and bottling industries, providing precise and controlled movement of products during packaging and filling operations.

5. Material Sorting and Grading

Plastic multiflex chains are used in material sorting and grading systems, facilitating the accurate separation and classification of materials.

6. Cleanroom Environments

Due to their cleanliness and hygiene properties, these chains are suitable for cleanroom environments, such as semiconductor manufacturing and medical device production.

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 the Right Plastic Multiflex Chains

1. Load Capacity

Consider the maximum load the chain needs to support to ensure it meets the specific application’s requirements.

2. Application Environment

Take into account factors such as temperature, humidity, exposure to chemicals, and other environmental conditions that may affect chain performance.

3. Chain Material

Choose the appropriate plastic material based on its mechanical properties, chemical resistance, and suitability for the intended application.

4. Chain Profile and Design

Select the chain profile and design that aligns with the conveyor system’s layout and product transfer requirements.

5. Environmental Factors

Consider factors such as dust, debris, and other contaminants that may be present in the application environment and choose a chain with suitable protective features.

6. Conveyor System Layout

Ensure the chain is compatible with the conveyor system layout, including the required length, width, and curvature.

7. Maintenance and Cleanability

Consider the ease of cleaning, maintenance, and availability of spare parts to minimize downtime and ensure smooth operations.

8. Cost Considerations

Evaluate the cost-effectiveness of the chain based on its performance, longevity, and overall value it brings to the application.

9. Supplier and Support

Choose a reputable supplier who can provide technical support, customization options, and reliable after-sales service.

Installation and Maintenance


1. Preparatory Steps

Prior to installation, ensure the conveyor system is properly prepared, including proper alignment and tensioning of the chain.

2. Chain Assembly

Assemble the plastic multiflex chain by interconnecting the modules and securing them with appropriate fasteners.

3. Sprocket Installation

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

4. Tracking Adjustment

Adjust the tracking of the chain by fine-tuning the position of the sprockets to ensure smooth and accurate movement along the conveyor path.


1. Regular Cleaning

Regularly clean the chain, removing any dirt, debris, or product residue that may accumulate over time.

2. Inspection

Periodically inspect the chain for signs of wear, damage, or misalignment, and address any issues promptly to prevent further damage.

3. Lubrication

Apply appropriate lubrication to the chain to ensure smooth articulation and reduce friction between the modules and sprockets.

4. Repair and Replacement

If any modules or sprockets are damaged or worn beyond repair, replace them with new ones to maintain optimal chain performance.

5. Training and Documentation

Train personnel on proper maintenance procedures and keep thorough documentation of maintenance activities for reference and audit purposes.
