Plastic multiflex chains are lightweight, reducing the overall weight of the conveyor system and minimizing energy consumption.

2. Flexibility

Plastic multiflex chains offer excellent flexibility, allowing them to adapt to complex conveyor layouts and angles.

3. High Strength

Despite their lightweight design, plastic multiflex chains are remarkably strong and can withstand heavy loads.

4. Low Maintenance

Plastic multiflex chains require minimal maintenance, reducing downtime and increasing productivity.

5. Noise Reduction

These chains operate quietly, contributing to a more comfortable and productive working environment.

6. Chemical Resistance

Plastic multiflex chains are resistant to various chemicals, making them suitable for even the harshest industrial environments.

7. Cleanliness and Hygiene

Easy to clean and sanitize, plastic multiflex chains are ideal for industries with strict cleanliness requirements.

8. Energy Efficiency

Due to their lightweight and low-friction design, plastic multiflex chains consume less energy during operation.

9. Versatility

Plastic multiflex chains can be customized to meet specific application requirements, making them suitable for various industries.

Applications of Plastic Multiflex Chains

1. Conveyor Systems

Plastic multiflex chains are widely used in conveyor systems, ensuring smooth and efficient product transportation.

2. Manufacturing and Assembly Lines

These chains are essential for manufacturing and assembly lines, facilitating the movement of products during production.

3. Distribution and Warehousing

Plastic multiflex chains are crucial for distribution and warehousing operations, enabling the efficient storage and retrieval of goods.

4. Packaging and Bottling

These chains play a vital role in packaging and bottling processes, ensuring the smooth flow of products.

5. Material Sorting and Grading

Plastic multiflex chains are commonly used for material sorting and grading applications, enabling accurate and efficient sorting.

6. Cleanroom Environments

Due to their cleanliness and hygiene properties, plastic multiflex chains are ideal for cleanroom environments, such as in the pharmaceutical or electronics industry.

Working Principle of Plastic Multiflex Chains

Plastic Multiflex Chains operates 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 the chain will need to support to ensure it can withstand the required weight.

2. Application Environment

Take into account the temperature, humidity, and any corrosive or abrasive substances present in the application environment.

3. Chain Material

Choose the appropriate plastic material based on its mechanical properties and resistance to chemicals or extreme conditions.

4. Chain Profile and Design

Select the chain profile and design that best suits the specific conveyor system layout and product handling requirements.

5. Environmental Factors

Consider any environmental factors that may affect the performance of the chains, such as dust, moisture, or temperature variations.

6. Conveyor System Layout

Take into account the conveyor system layout, including curves, inclines, declines, and any special requirements.

7. Maintenance and Cleanability

Consider the ease of maintenance and cleanability of the chains to ensure smooth operation and hygiene compliance.

8. Cost Considerations

Weigh the cost of the chains against their performance and durability to achieve the best value for money.

9. Supplier and Support

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

Installation and Maintenance of Plastic Multiflex Chains


1. Preparatory Steps

Ensure that the conveyor system is properly prepared for the installation of the plastic multiflex chains.

2. Chain Assembly

Assemble the plastic multiflex chains according to the manufacturer’s instructions, connecting the modules securely.

3. Sprocket Installation

Mount the sprockets or sprocket wheels accurately, ensuring proper engagement with the chain modules.

4. Tracking Adjustment

Adjust the tracking of the plastic multiflex chains to ensure they run smoothly and stay aligned with the conveyor path.


1. Regular Cleaning

Regularly clean the plastic multiflex chains to remove any debris, dust, or contaminants that may affect their performance.

2. Inspection

Periodically inspect the chains for signs of wear, damage, or misalignment, and take appropriate action to address any issues.

3. Lubrication

Apply lubrication to the chain and sprockets as recommended by the manufacturer to reduce friction and prevent premature wear.

4. Repair and Replacement

If any chain modules or sprockets are damaged or worn out, replace them promptly to maintain the efficiency of the conveyor system.

5. Training and Documentation

Provide proper training to maintenance personnel on the installation, maintenance, and troubleshooting of plastic multiflex chains. Keep detailed documentation of maintenance activities and any modifications made to the chains.

Sprockets and Their Importance in Plastic Multiflex Chains

Sprockets are crucial components that work in conjunction with plastic multiflex chains to ensure smooth and efficient operation.

They engage with the tabs on the chain modules, providing the driving force to propel the chain forward.

Properly designed and installed sprockets ensure that the chain articulates accurately and maintains synchronization.

Choosing the right sprockets for plastic multiflex chains is essential to achieve optimal performance and longevity.
