Plastic Multiflex Chains for durable conveyor belt performance

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.

Multiflex Chain


1. Lightweight

Plastic multiflex chains are known for their lightweight nature, which reduces the overall weight of the conveyor system. This not only makes installation easier but also minimizes the load on supporting structures.

Plastic multiflex chains operate quietly, minimizing noise pollution in the workplace and creating a more comfortable and productive environment.

6. Chemical Resistance

These chains are resistant to various chemicals and substances, making them suitable for applications in industries where exposure to corrosive materials is common.

7. Cleanliness and Hygiene

Plastic multiflex chains are easy to clean and maintain a high level of cleanliness, making them ideal for industries with strict hygiene standards such as food processing and pharmaceuticals.

8. Energy Efficiency

The lightweight design and low friction of plastic multiflex chains contribute to energy efficiency, reducing power consumption and operational costs.

9. Versatility

Plastic multiflex chains can be customized and adapted to suit a wide range of applications, providing flexibility and versatility in material handling systems.

Multiflex Chains Application


1. Conveyor Systems

Plastic multiflex chains are commonly used in conveyor systems for industries such as automotive, logistics, and manufacturing. They ensure efficient movement of products along the production line.

2. Manufacturing and Assembly Lines

In manufacturing and assembly lines, plastic multiflex chains facilitate the smooth flow of materials, enabling streamlined production processes and increasing productivity.

3. Distribution and Warehousing

Plastic multiflex chains are utilized in distribution and warehousing facilities to transport goods between different areas, ensuring efficient and organized storage and distribution operations.

4. Packaging and Bottling

Plastic multiflex chains play a crucial role in packaging and bottling industries, providing reliable and precise movement of products during the packaging and bottling processes.

5. Material Sorting and Grading

These chains are used in material sorting and grading systems, allowing for accurate separation and categorization of different materials based on their size, shape, or other properties.

6. Cleanroom Environments

Plastic multiflex chains are suitable for cleanroom environments, where maintaining a contaminant-free atmosphere is essential. Their hygienic properties ensure product integrity and safety.

Multiflex Chain Application and Maintenance

Working Principle:

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.

Multiflex Chain Advantages

Choosing the Right Plastic Multiflex Chains:

1. Load Capacity

Consider the maximum load the chain will need to carry and choose a chain with a suitable load capacity to ensure reliable and safe operation.

2. Application Environment

Evaluate the environmental conditions, such as temperature, moisture, and exposure to chemicals, to select a chain material that can withstand these factors.

3. Chain Material

Choose a chain material based on the specific requirements of the application, considering factors such as strength, durability, and chemical resistance.

4. Chain Profile and Design

Select a chain profile and design that aligns with the conveyor layout and the type of products or materials being conveyed.

5. Environmental Factors

Take into account factors like dust, debris, and other environmental contaminants that may affect chain performance and choose a chain with appropriate features to mitigate these issues.

6. Conveyor System Layout

Analyze the conveyor system layout and determine the chain length, configuration, and any necessary accessories or attachments required for optimal performance.

7. Maintenance and Cleanability

Consider the ease of maintenance and cleanability of the chain to minimize downtime and ensure compliance with hygiene standards.

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 that provides reliable technical support and after-sales service to ensure a smooth and successful implementation of the plastic multiflex chain.

Multiflex Chain Maintenance

Installation and Maintenance:


1. Preparatory Steps

Prior to installation, ensure that the conveyor system is properly prepared, including the alignment of supporting structures and the availability of necessary tools and equipment.

2. Chain Assembly

Assemble the plastic multiflex chain by interlocking the modules, ensuring that the tabs and hinges are securely connected.

3. Sprocket Installation

Install the sprockets or sprocket wheels at appropriate intervals along the conveyor system, ensuring proper alignment and engagement with the chain modules.

4. Tracking Adjustment

Adjust the tracking of the chain by aligning the sprockets and ensuring that the chain stays on the intended path without drifting or misalignment.


1. Regular Cleaning

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

2. Inspection

Periodically inspect the chain for signs of wear, damage, or misalignment. Address any issues promptly to prevent further damage or system failure.

3. Lubrication

Apply appropriate lubrication to the chain to reduce friction and ensure smooth movement. Follow the manufacturer’s recommendations for lubrication intervals and types.

4. Repair and Replacement

If any modules or components of the chain are damaged or worn out, replace them promptly to maintain optimal performance and prevent system downtime.

5. Training and Documentation

Provide training to personnel responsible for chain maintenance and document the maintenance procedures to ensure consistency and adherence to best practices.
