Plastic Multiflex Chains for vertical 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.

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. This makes them ideal for applications where weight reduction is crucial, such as vertical conveyors.

2. Flexibility

Plastic multiflex chains offer exceptional flexibility, allowing them to navigate complex conveyor paths and accommodate changes in direction. This flexibility enhances system efficiency and adaptability.

3. High Strength

Despite their lightweight nature, plastic multiflex chains exhibit high tensile strength, ensuring reliable and durable performance in demanding vertical applications.

4. Low Maintenance

Plastic multiflex chains require minimal maintenance compared to traditional metal chains. They are resistant to corrosion, wear, and lubrication, reducing downtime and maintenance costs.

5. Noise Reduction

Plastic multiflex chains operate silently, reducing noise pollution in the workplace. This is particularly advantageous in environments where noise levels need to be minimized.

6. Chemical Resistance

The thermoplastic materials used in plastic multiflex chains offer excellent resistance to chemicals, making them suitable for applications involving exposure to corrosive substances.

7. Cleanliness and Hygiene

Plastic multiflex chains are easy to clean and maintain high hygiene standards. Their smooth surfaces prevent the accumulation of debris, ensuring product integrity and cleanliness.

8. Energy Efficiency

Due to their lightweight construction, plastic multiflex chains require less power to operate, resulting in energy savings and reduced operating costs.

9. Versatility

Plastic multiflex chains are compatible with various conveying systems and can be customized to meet specific application requirements, providing versatility in design and functionality.

Applications of Plastic Multiflex Chains

1. Conveyor Systems

Plastic multiflex chains are widely used in conveyor systems for industries such as food processing, pharmaceuticals, and automotive, providing efficient and reliable material handling.

2. Manufacturing and Assembly Lines

Plastic multiflex chains facilitate the smooth flow of components and products in manufacturing and assembly lines, ensuring seamless production processes.

3. Distribution and Warehousing

In distribution and warehousing operations, plastic multiflex chains enable efficient movement and sorting of goods, optimizing storage and logistics operations.

4. Packaging and Bottling

Plastic multiflex chains are ideal for packaging and bottling applications, offering precise and controlled product handling, especially in high-speed production lines.

5. Material Sorting and Grading

Plastic multiflex chains contribute to accurate material sorting and grading processes, ensuring consistent product quality and reducing errors.

6. Cleanroom Environments

Plastic multiflex chains are suitable for cleanroom environments, where maintaining high levels of cleanliness and preventing contamination are critical.

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.

Selecting the Right Plastic Multiflex Chains

1. Load Capacity

Consider the weight and size of the products or materials to be conveyed to determine the appropriate load capacity of the plastic multiflex chains.

2. Application Environment

Evaluate the environmental conditions, such as temperature, humidity, and exposure to chemicals, to select chains that can withstand the specific application environment.

3. Chain Material

Choose the appropriate thermoplastic material, such as polyethylene or polypropylene, based on factors like chemical resistance, durability, and operating temperature range.

4. Chain Profile and Design

Select the chain profile and design that aligns with the conveyor system layout and the specific requirements of the application.

5. Environmental Factors

Consider factors such as dust, moisture, and abrasive substances present in the environment and choose chains that can withstand these conditions without compromising performance.

6. Conveyor System Layout

Analyze the layout and configuration of the conveyor system to ensure that the selected plastic multiflex chains can be easily integrated and provide optimal performance.

7. Maintenance and Cleanability

Consider the ease of maintenance and cleanability of the chains to minimize downtime and ensure hygienic operation.

8. Cost Considerations

Evaluate the cost-effectiveness of the chains, taking into account factors such as initial investment, maintenance requirements, and expected lifespan.

9. Supplier and Support

Choose a reputable supplier that offers reliable technical support, customization options, and prompt after-sales service.

Installation and Maintenance of Plastic Multiflex Chains


1. Preparatory Steps

Prior to installation, ensure that the conveyor system is properly prepared, including aligning the sprockets, clearing any obstacles, and confirming the correct chain length.

2. Chain Assembly

Assemble the plastic multiflex chains according to the manufacturer’s instructions, ensuring proper alignment and engagement of the modules.

3. Sprocket Installation

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

4. Tracking Adjustment

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


1. Regular Cleaning

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

2. Inspection

Periodically inspect the chains for signs of wear, damage, or misalignment. Replace any worn-out or damaged modules promptly.

3. Lubrication

Apply a suitable lubricant to the chain modules and sprockets as recommended by the manufacturer to ensure smooth operation and prevent premature wear.

4. Repair and Replacement

If any part of the plastic multiflex chains is damaged or worn beyond repair, replace it with a new module or chain segment to maintain optimal performance.

5. Training and Documentation

Train maintenance personnel on proper chain maintenance procedures and keep comprehensive documentation of maintenance activities for reference and future planning.
