Plastic Multiflex Chains for Heavy-Duty Pallet Handling

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, reducing the overall weight and energy consumption of the conveyor system. This makes them ideal for applications where weight is a critical factor.

2. Flexibility

Due to their modular design, plastic multiflex chains offer exceptional flexibility, allowing them to navigate tight curves and complex conveyor layouts. This flexibility enables smooth and efficient material handling.

3. High Strength

Despite their lightweight construction, plastic multiflex chains exhibit impressive strength and durability. They can withstand heavy loads and resist wear, ensuring a long lifespan and reliable performance.

4. Low Maintenance

Plastic multiflex chains require minimal maintenance compared to traditional metal chains. They are resistant to corrosion and do not require lubrication, resulting in reduced downtime and cost savings.

5. Noise Reduction

These chains generate less noise during operation, creating a quieter and more comfortable working environment. This is particularly beneficial in facilities where noise reduction is essential.

6. Chemical Resistance

Plastic multiflex chains are resistant to a wide range of chemicals, including acids, alkalis, and solvents. This chemical resistance makes them suitable for applications where exposure to corrosive substances is common.

7. Cleanliness and Hygiene

The smooth surface of plastic multiflex chains makes them easy to clean and maintain high standards of cleanliness and hygiene. They are often used in industries with strict sanitation requirements, such as food processing.

8. Energy Efficiency

Due to their lightweight and low-friction design, plastic multiflex chains contribute to energy savings in conveyor systems. They require less power to operate, resulting in reduced energy consumption and lower operating costs.

9. Versatility

Plastic multiflex chains can be customized to suit specific application requirements. They are available in various sizes, configurations, and materials, allowing for versatile use in different industries and applications.

Applications of Plastic Multiflex Chains

1. Conveyor Systems

Plastic multiflex chains are widely used in conveyor systems for transporting goods and materials. They ensure smooth and efficient material flow, contributing to increased productivity.

2. Manufacturing and Assembly Lines

In manufacturing and assembly lines, plastic multiflex chains facilitate the movement of products and components, allowing for efficient production processes and reduced handling times.

3. Distribution and Warehousing

Plastic multiflex chains are used in distribution and warehousing facilities for sorting, storing, and transporting goods. They enable seamless material handling and maximize storage space utilization.

4. Packaging and Bottling

Plastic multiflex chains are essential components in packaging and bottling applications. They ensure the smooth transfer and accurate positioning of packages and bottles, improving packaging efficiency.

5. Material Sorting and Grading

In material sorting and grading operations, plastic multiflex chains enable the precise movement and separation of materials based on their size, shape, or other attributes.

6. Cleanroom Environments

Plastic multiflex chains are suitable for cleanroom environments where contamination control is crucial. They meet stringent cleanliness requirements and minimize the risk of 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.

Selecting the Right Plastic Multiflex Chains

1. Load Capacity

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

2. Application Environment

Consider the operating conditions, such as temperature, humidity, and exposure to chemicals or abrasives, and choose a chain material that can withstand these conditions.

3. Chain Material

Select the appropriate thermoplastic material, such as PE or PP, based on factors like strength, durability, chemical resistance, and compatibility with the conveyed materials.

4. Chain Profile and Design

Choose a chain profile and design that aligns with the specific requirements of the conveyor system, including the desired speed, product characteristics, and layout constraints.

5. Environmental Factors

Consider any environmental regulations or standards that may impact chain selection, such as food safety certifications or fire resistance requirements.

6. Conveyor System Layout

Evaluate the conveyor system layout and determine the chain length, width, and configuration necessary to achieve optimal performance and material flow.

7. Maintenance and Cleanability

Assess the ease of maintenance and cleanability of the chain, considering factors such as access for cleaning, resistance to debris buildup, and compatibility with cleaning agents.

8. Cost Considerations

Weigh the upfront and long-term costs of the chain, including purchase price, maintenance expenses, and potential productivity gains or savings.

9. Supplier and Support

Choose a reputable supplier who can provide technical expertise, reliable products, and ongoing support for the plastic multiflex chains.

Installation and Maintenance


1. Preparatory Steps

Prior to installation, ensure that the conveyor system is properly prepared, including correct alignment, tensioning, and lubrication of other components.

2. Chain Assembly

Assemble the plastic multiflex chain by connecting the individual modules, ensuring proper alignment and engagement of the tabs or hinges.

3. Sprocket Installation

Install the sprockets or sprocket wheels onto the drive and idle shafts, ensuring proper alignment and engagement with the chain modules.

4. Tracking Adjustment

Adjust the tension and tracking of the chain to ensure smooth and reliable operation, making any necessary adjustments to the sprockets or chain guides.


1. Regular Cleaning

Regularly clean the plastic multiflex chain to remove dirt, debris, and product residues that may accumulate and affect its performance.

2. Inspection

Periodically inspect the chain for any signs of wear, damage, or misalignment. Replace any worn or damaged modules or components as needed.

3. Lubrication

Some plastic multiflex chains may require periodic lubrication of the sprockets or chain guides. Follow the manufacturer’s recommendations for lubrication intervals and appropriate lubricants.

4. Repair and Replacement

If any part of the chain becomes damaged or worn beyond repair, replace it promptly to avoid potential disruptions or failures in the conveyor system.

5. Training and Documentation

Ensure that personnel responsible for chain maintenance receive proper training and have access to documentation, such as maintenance manuals or guidelines.

Importance of Sprockets for Plastic Multiflex Chains

Sprockets play a crucial role in the operation of plastic multiflex chains. They provide the driving force that propels the chain and ensure proper engagement with the chain modules. The design and compatibility of the sprockets with the chain are essential for achieving smooth and reliable movement. Choosing the right sprockets, in terms of tooth profile, diameter, and material, is crucial to maintain optimal performance and maximize the lifespan of the plastic multiflex chain.
