Plastic Multiflex Chains for heavy-duty applications

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.

Advantages of Plastic Multiflex Chains:

1. Lightweight

Plastic multiflex chains are made from lightweight thermoplastic materials, such as polyethylene or polypropylene, which contribute to the overall weight reduction of the conveyor system. This not only improves energy efficiency but also makes handling and installation easier.

2. Flexibility

The modular design of plastic multiflex chains allows for flexibility in various directions. These chains can adapt to curved paths, inclines, and declines, providing smooth and efficient material flow even in complex conveyor layouts.

3. High Strength

Despite their lightweight nature, plastic multiflex chains exhibit high tensile strength and load-carrying capacity. This makes them suitable for heavy-duty applications where the conveyance of bulky or heavy items is required.

4. Low Maintenance

Plastic multiflex chains require minimal maintenance compared to traditional metal chains. They are resistant to corrosion, rust, and wear, reducing the need for frequent lubrication or replacement. This lowers maintenance costs and increases operational uptime.

5. Noise Reduction

Plastic multiflex chains operate quietly, minimizing noise pollution in the working environment. This is particularly beneficial in settings where noise levels need to be controlled, such as in cleanrooms or manufacturing facilities located near residential areas.

6. Chemical Resistance

Plastic multiflex chains are resistant to a wide range of chemicals, including oils, greases, solvents, and cleaning agents. This allows them to withstand harsh operating conditions and maintain their performance and durability over time.

7. Cleanliness and Hygiene

Due to their smooth surface and non-absorbent properties, plastic multiflex chains are easy to clean and sanitize. They are suitable for applications in industries with strict hygiene standards, such as food processing, pharmaceuticals, and healthcare.

8. Energy Efficiency

Plastic multiflex chains contribute to energy savings in conveyor systems. Their lightweight construction and low friction properties require less power for operation, resulting in reduced energy consumption and lower operational costs.

9. Versatility

Plastic multiflex chains can be customized and adapted to various applications and industries. They are available in different widths, lengths, and configurations, allowing for easy integration into new or existing conveyor systems.

Applications of Plastic Multiflex Chains:

1. Conveyor Systems

Plastic multiflex chains are widely used in conveyor systems for industries such as automotive, logistics, and e-commerce. They enable the efficient movement of products along the production or distribution line, increasing productivity and reducing manual labor.

2. Manufacturing and Assembly Lines

Plastic multiflex chains play a crucial role in manufacturing and assembly lines, where they facilitate the smooth transfer of components or products between workstations. Their flexibility allows for easy integration into complex production processes.

3. Distribution and Warehousing

In distribution and warehousing facilities, plastic multiflex chains are utilized for the sorting, accumulation, and distribution of goods. Their robust construction ensures reliable performance even in demanding environments with high throughput requirements.

4. Packaging and Bottling

Plastic multiflex chains are ideal for packaging and bottling applications, where they provide a reliable means of conveying containers or packaged products. The low friction properties of the chains minimize the risk of product damage during transportation.

5. Material Sorting and Grading

Plastic multiflex chains are employed in material sorting and grading systems, enabling the efficient separation and categorization of different materials based on their size, shape, or other characteristics. Their flexibility allows for precise and accurate material handling.

6. Cleanroom Environments

Due to their cleanliness and hygiene properties, plastic multiflex chains are widely used in cleanroom environments, such as semiconductor manufacturing or pharmaceutical production. They help maintain the integrity of the cleanroom by minimizing particle generation.

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 that the chain will need to carry to ensure it meets the specific application requirements.

2. Application Environment

Take into account the environmental conditions, such as temperature, humidity, and presence of chemicals or contaminants, to select a chain material that can withstand the application environment.

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 a chain profile and design that best fits the conveyor system layout and the type of products or materials being conveyed.

5. Environmental Factors

Consider any specific environmental factors, such as the presence of water, dust, or corrosive substances, and choose a chain that can withstand these conditions.

6. Conveyor System Layout

Take into account the layout and configuration of the conveyor system to ensure proper chain selection and compatibility with existing equipment.

7. Maintenance and Cleanability

Consider the ease of cleaning, maintenance, and accessibility for inspections or repairs to minimize downtime and ensure smooth operation.

8. Cost Considerations

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

9. Supplier and Support

Choose a reputable supplier who can provide technical support, customization options, and reliable after-sales service for the plastic multiflex chains.

Installation and Maintenance:


1. Preparatory Steps: Ensure the conveyor system is properly prepared, including cleaning the installation area and aligning the frame components.

2. Chain Assembly: Connect the plastic multiflex chain modules, ensuring proper alignment and engagement of the tabs or hinges.

3. Sprocket Installation: Install the sprockets or sprocket wheels at the appropriate positions, ensuring proper engagement with the chain modules.

4. Tracking Adjustment: Adjust the chain tracking using appropriate tensioning devices to ensure proper alignment and prevent chain deviation.


1. Regular Cleaning: Clean the plastic multiflex chains regularly to remove any debris, dirt, or contaminants that may hinder smooth operation.

2. Inspection: Periodically inspect the chain for signs of wear, damage, or misalignment. Replace any worn or damaged modules or sprockets promptly.

3. Lubrication: Apply appropriate lubrication to the chain, as recommended by the manufacturer, to reduce friction and extend the chain’s lifespan.

4. Repair and Replacement: Repair or replace any damaged or worn components to ensure the chain’s optimal performance and longevity.

5. Training and Documentation: Train personnel on proper maintenance procedures and keep detailed documentation of maintenance activities for reference and troubleshooting.

Sprockets and Plastic Multiflex Chains:

Sprockets play a crucial role in the operation of plastic multiflex chains. They engage with the tabs or hinges on the chain modules, providing the driving force to propel the chain forward. The design and configuration of the sprockets must be compatible with the specific chain profile and size to ensure smooth and synchronized movement.
