Plastic multiflex chains offer exceptional flexibility, allowing them to adapt to different conveyor layouts and navigate around obstacles with ease.

3. High Strength

Despite their lightweight design, plastic multiflex chains offer high tensile strength, enabling them to handle heavy loads and withstand demanding applications.

4. Low Maintenance

Plastic multiflex chains require minimal maintenance, thanks to their durable construction and resistance to wear, corrosion, and impact.

5. Noise Reduction

Plastic multiflex chains operate quietly, reducing noise levels in the workplace and creating a more comfortable working environment.

6. Chemical Resistance

Plastic multiflex chains exhibit excellent resistance to various chemicals, making them suitable for applications involving exposure to corrosive substances.

7. Cleanliness and Hygiene

Plastic multiflex chains are easy to clean, ensuring compliance with hygiene standards in industries such as food processing and pharmaceuticals.

8. Energy Efficiency

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

9. Versatility

Plastic multiflex chains can be customized to meet specific application requirements, making them suitable for a wide range of industries and processes.

Applications of Plastic Multiflex Chains

1. Conveyor Systems

Plastic multiflex chains are commonly used in conveyor systems, facilitating the movement of products and materials in industries such as manufacturing, distribution, and packaging.

2. Manufacturing and Assembly Lines

Plastic multiflex chains play a crucial role in manufacturing and assembly lines, ensuring the smooth and efficient transfer of components during production processes.

3. Distribution and Warehousing

In distribution and warehousing operations, plastic multiflex chains are utilized to transport goods, organize inventory, and optimize logistical processes.

4. Packaging and Bottling

Plastic multiflex chains are integral to packaging and bottling applications, facilitating the movement and positioning of containers during filling, sealing, and labeling processes.

5. Material Sorting and Grading

Plastic multiflex chains are employed in material sorting and grading systems, enabling the efficient segregation and categorization of products based on specific criteria.

6. Cleanroom Environments

Plastic multiflex chains are suitable for cleanroom environments, as they meet strict cleanliness requirements and ensure contamination-free operations.

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 weight the chain will need to support to ensure it can handle the required load without compromising performance.

2. Application Environment

Evaluate the operating environment for factors such as temperature, moisture, chemicals, and cleanliness requirements to select a chain material with the appropriate properties.

3. Chain Material

Choose a chain material, such as polyethylene or polypropylene, based on its mechanical, chemical, and thermal characteristics, ensuring compatibility with the application requirements.

4. Chain Profile and Design

Select a chain profile and design that aligns with the conveyor system layout and the specific product or material being transported.

5. Environmental Factors

Consider external factors like dust, debris, and UV exposure to determine the level of protection and resilience required for the chain.

6. Conveyor System Layout

Analyze the conveyor system layout to determine the necessary chain length, width, and configuration for seamless integration and optimal performance.

7. Maintenance and Cleanability

Assess the ease of maintenance and cleanability of the chain to ensure minimal downtime and compliance with industry cleanliness standards.

8. Cost Considerations

Weigh the cost of the chain against its expected lifespan, maintenance requirements, and overall performance to determine the most cost-effective solution.

9. Supplier and Support

Choose a reputable supplier that offers technical support, customization options, and reliable after-sales service to ensure long-term satisfaction with the chain.

Installation and Maintenance of Plastic Multiflex Chains


1. Preparatory Steps

Prior to installation, ensure the conveyor system is properly prepared, with correct alignment and sufficient space for the chain.

2. Chain Assembly

Connect the individual plastic links or modules to form a continuous chain loop, following the manufacturer’s instructions and ensuring proper alignment.

3. Sprocket Installation

Install the sprockets or sprocket wheels at appropriate intervals, engaging with the tabs on the modules to facilitate the chain’s movement.

4. Tracking Adjustment

Adjust the tracking of the chain to ensure it remains centered on the conveyor and does not deviate from the intended path during operation.


1. Regular Cleaning

Maintain cleanliness by regularly removing debris, dust, and other contaminants from the chain to prevent buildup and ensure smooth operation.

2. Inspection

Periodically inspect the chain for signs of wear, damage, or misalignment, addressing any issues promptly to prevent further damage or operational disruptions.

3. Lubrication

Apply lubrication to the chain as recommended by the manufacturer to minimize friction, reduce wear, and prolong the chain’s lifespan.

4. Repair and Replacement

Repair or replace damaged or worn-out sections of the chain, ensuring that the replacement parts match the original specifications and meet the necessary performance requirements.

5. Training and Documentation

Train personnel on proper maintenance procedures and keep detailed documentation of maintenance schedules, repairs, and replacements for reference and future planning.

Sprockets and Their Importance in Relation to Plastic Multiflex Chains

Sprockets are a critical component in the operation of plastic multiflex chains. They engage with the tabs on the chain modules, providing the driving force and guiding the chain along the conveyor path. Properly matched sprockets ensure smooth and synchronized movement of the chain, minimizing wear and optimizing chain performance. The design and size of the sprockets must align with the chain’s profile and configuration to ensure efficient power transmission and reliable operation.
