Plastic Multiflex Chains for high-speed canning lines

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 incredibly lightweight, which reduces the overall weight of the conveyor system and allows for smoother operation.

2. Flexibility

These chains offer excellent flexibility, allowing them to adapt to various conveyor layouts and handle curved or inclined paths with ease.

3. High Strength

Despite their lightweight nature, plastic multiflex chains are exceptionally strong and can withstand heavy loads without compromising performance.

4. Low Maintenance

Due to their durable construction and self-lubricating properties, these chains require minimal maintenance, resulting in reduced downtime and lower operating costs.

5. Noise Reduction

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

6. Chemical Resistance

These chains exhibit excellent resistance to various chemicals, ensuring their longevity and reliability even in harsh industrial environments.

7. Cleanliness and Hygiene

Plastic multiflex chains are easy to clean and sanitize, making them suitable for applications that require strict hygiene standards, such as food processing.

8. Energy Efficiency

With their low friction and smooth operation, these chains contribute to energy savings and reduced operational 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 widely used in conveyor systems, facilitating the smooth transport of goods and materials in industries such as manufacturing, warehousing, and distribution.

2. Manufacturing and Assembly Lines

These chains play a crucial role in manufacturing and assembly lines, ensuring efficient movement and precise positioning of components or products.

3. Distribution and Warehousing

In distribution centers and warehouses, plastic multiflex chains are employed to streamline material flow, facilitating order fulfillment and inventory management.

4. Packaging and Bottling

Plastic multiflex chains are utilized in high-speed canning lines and other packaging and bottling applications to ensure smooth and reliable product handling.

5. Material Sorting and Grading

These chains are commonly used in material sorting and grading systems, enabling efficient separation and classification of various materials based on their characteristics.

6. Cleanroom Environments

Plastic multiflex chains find application in cleanroom environments, where cleanliness and precision are paramount, such as in the semiconductor and pharmaceutical industries.

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 load the chain will need to support and choose a chain with the appropriate load capacity to ensure safe and efficient operation.

2. Application Environment

Take into account the environmental conditions, such as temperature, humidity, and exposure to chemicals, to select a chain that can withstand the specific application requirements.

3. Chain Material

Choose a chain material, such as polyethylene (PE) or polypropylene (PP), based on the desired properties and compatibility with the conveyed products or materials.

4. Chain Profile and Design

Select a chain profile and design that aligns with the conveyor system layout and ensures smooth product transfer without jams or disruptions.

5. Environmental Factors

Consider factors such as dust, debris, or moisture present in the environment and choose a chain with appropriate features to mitigate any potential issues.

6. Conveyor System Layout

Analyze the conveyor system layout and requirements to determine the necessary chain length, configuration, and any additional accessories or components required.

7. Maintenance and Cleanability

Evaluate the ease of maintenance and cleanability of the chain, ensuring it can be readily cleaned, inspected, and lubricated as necessary to maintain optimal performance.

8. Cost Considerations

Weigh the initial cost, lifecycle cost, and potential savings in terms of reduced maintenance and downtime when selecting the most cost-effective chain option.

9. Supplier and Support

Choose a reliable supplier who can provide technical expertise, assistance with chain selection, and ongoing support throughout the lifespan of the chain.

Installation and Maintenance


1. Preparatory Steps: Ensure the conveyor system is properly prepared for chain installation, including cleaning the track and positioning the sprockets.

2. Chain Assembly: Assemble the plastic multiflex chain by interlocking the modules, following the manufacturer’s instructions and ensuring proper alignment.

3. Sprocket Installation: Install the sprockets onto the conveyor system, aligning them with the chain and ensuring proper engagement with the module tabs.

4. Tracking Adjustment: Adjust the chain tracking, if necessary, to ensure it remains centered and aligned within the conveyor system for optimal performance.


1. Regular Cleaning: Regularly clean the chain and remove any debris or buildup that may affect its performance or cause premature wear.

2. Inspection: Periodically inspect the chain for signs of damage, wear, or misalignment, and address any issues promptly to prevent further damage.

3. Lubrication: Apply appropriate lubrication to the chain as recommended by the manufacturer to reduce friction and ensure smooth operation.

4. Repair and Replacement: Replace any damaged or worn-out modules or components to maintain the chain’s integrity and performance.

5. Training and Documentation: Provide proper training to maintenance personnel on chain inspection, cleaning, and maintenance procedures, and maintain accurate documentation of maintenance activities.
