Do Plastic Multiflex Chains offer smooth and quiet operation?

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 lightweight, which reduces the overall weight of the conveyor system and allows for easier installation, maintenance, and operation.

2. Flexibility

These chains are highly flexible, allowing for smooth movement around bends, curves, and corners without compromising on performance.

3. High Strength

Despite their lightweight construction, plastic multiflex chains offer high strength and load-carrying capacity, making them suitable for heavy-duty applications.

4. Low Maintenance

Due to their durable thermoplastic composition, these chains require minimal maintenance and have a longer service life compared to traditional metal chains.

5. Noise Reduction

Plastic multiflex chains offer smooth and quiet operation, reducing noise levels in the working environment and improving overall workplace comfort.

6. Chemical Resistance

These chains exhibit excellent chemical resistance, making them suitable for use in industries where exposure to chemicals or corrosive substances is common.

7. Cleanliness and Hygiene

Plastic multiflex chains are easy to clean and maintain, making them ideal for applications in industries such as food processing and pharmaceuticals that require high standards of cleanliness and hygiene.

8. Energy Efficiency

Their lightweight and low-friction design contribute to energy efficiency, resulting in reduced power consumption and cost savings.

9. Versatility

Plastic multiflex chains can be customized and adapted to various conveyor layouts and requirements, allowing for greater flexibility and versatility in different applications.

Applications of Plastic Multiflex Chains

1. Conveyor Systems

Plastic multiflex chains are widely used in conveyor systems to transport products or materials efficiently and smoothly in industries such as manufacturing, logistics, and e-commerce.

2. Manufacturing and Assembly Lines

These chains find applications in manufacturing and assembly lines, enabling the seamless movement of components and products during the production process.

3. Distribution and Warehousing

In distribution and warehousing facilities, plastic multiflex chains are utilized for sorting, transferring, and storing various items to optimize logistics operations.

4. Packaging and Bottling

Plastic multiflex chains are commonly employed in packaging and bottling industries to facilitate the smooth flow of containers, boxes, and other packaged goods.

5. Material Sorting and Grading

These chains are suitable for material sorting and grading applications, enabling efficient separation and categorization of different types of materials or products based on specific criteria.

6. Cleanroom Environments

Due to their cleanliness, hygiene, and low particle generation properties, plastic multiflex chains are ideal for use in cleanroom environments that require strict contamination control.

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 weight and load requirements of your application to ensure that the selected chain can handle the required load capacity.

2. Application Environment

Assess the environmental conditions, such as temperature, humidity, and exposure to chemicals, to choose a chain that can withstand the application environment.

3. Chain Material

Select the appropriate plastic material (e.g., PE or PP) based on its mechanical properties and compatibility with the conveyed products or materials.

4. Chain Profile and Design

Choose a chain with the desired profile and design features, such as straight or curved modules, to meet the specific requirements of your conveyor system.

5. Environmental Factors

Consider factors like abrasion resistance, UV resistance, and impact resistance based on the working conditions and potential exposure to external elements.

6. Conveyor System Layout

Analyze the layout and configuration of your conveyor system to ensure that the chosen chain can be easily integrated and provide optimal performance.

7. Maintenance and Cleanability

Evaluate the ease of cleaning, maintenance requirements, and availability of spare parts to minimize downtime and ensure smooth operation.

8. Cost Considerations

Weigh the initial cost, long-term durability, and overall value proposition of the chain to make an informed decision that aligns with your budget and requirements.

9. Supplier and Support

Choose a reliable supplier that offers technical support, customization options, and after-sales service to ensure a seamless experience throughout the chain’s lifecycle.

Installation and Maintenance of Plastic Multiflex Chains


1. Preparatory Steps

Prior to installation, ensure that the conveyor system is properly prepared, including cleaning the track, aligning the sprockets, and checking for any obstructions.

2. Chain Assembly

Assemble the plastic multiflex chain by interlocking the modules together, ensuring that they are correctly aligned and securely connected.

3. Sprocket Installation

Install the sprockets onto the drive shaft or shafts, ensuring proper alignment and engagement with the tabs on the chain modules.

4. Tracking Adjustment

Adjust the tracking of the chain to ensure it runs smoothly and stays aligned with the conveyor track, making any necessary adjustments to the sprockets or tensioning devices.


1. Regular Cleaning

Regularly clean the plastic multiflex chain to remove debris, dirt, and contaminants that could affect its performance or cause premature wear.

2. Inspection

Periodically inspect the chain for signs of damage, wear, or misalignment. Replace any worn-out or damaged modules promptly to prevent further issues.

3. Lubrication

Apply a suitable lubricant to the chain and sprockets as recommended by the manufacturer to minimize friction and ensure smooth operation.

4. Repair and Replacement

If any modules or components are damaged beyond repair, replace them with new ones to maintain optimal performance and prevent unexpected failures.

5. Training and Documentation

Provide training to personnel responsible for operating and maintaining the conveyor system. Keep detailed documentation, including maintenance schedules and records, to track the chain’s performance and maintenance history.

Sprockets and their Importance in Plastic Multiflex Chains

Sprockets play a crucial role in the operation of plastic multiflex chains. They are specially designed toothed wheels that engage with the tabs on the chain modules, driving the chain forward and maintaining its synchronized movement.

Properly selected and installed sprockets ensure smooth and efficient operation, preventing chain slippage or misalignment. They help distribute the load evenly across the chain, reducing stress and prolonging the chain’s service life. The correct alignment of the sprockets also contributes to the overall quiet and smooth operation of the chain system.
