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

  • Lightweight
  • Flexibility
  • High Strength
  • Low Maintenance
  • Noise Reduction
  • Chemical Resistance
  • Cleanliness and Hygiene
  • Energy Efficiency
  • Versatility

1. Conveyor Systems

Plastic multiflex chains are widely used in conveyor systems as they offer the flexibility and strength required to move products and materials smoothly and efficiently along the conveyor path. These chains are ideal for conveying a wide range of products, from light and fragile items to heavy and bulky materials, in industries such as food and beverage, automotive, and pharmaceuticals.

2. Manufacturing and Assembly Lines

Plastic multiflex chains are also used in manufacturing and assembly lines, where they enable smooth and reliable movement of products and materials between different stages of the production process. Their flexibility allows them to negotiate corners and turns, while their low maintenance requirements make them a cost-effective solution for high-volume operations.

3. Distribution and Warehousing

In distribution and warehousing, plastic multiflex chains are used in conveyor systems to move products and materials from one point to another. Their versatility allows them to be customized to suit the specific requirements of each operation, while their low noise and cleanliness make them an attractive option for applications where hygiene and safety are important.

4. Packaging and Bottling

Plastic multiflex chains are widely used in packaging and bottling applications, where they enable the efficient and reliable transfer of products and materials along the production line. Their flexibility and low maintenance make them a popular choice for high-speed operations, while their chemical resistance ensures they can withstand exposure to a variety of substances used in packaging and bottling.

5. Material Sorting and Grading

Plastic multiflex chains are also used in material sorting and grading applications, where they enable products and materials to be sorted and graded based on size, shape, and other characteristics. Their flexibility allows them to handle a wide range of products, while their low maintenance ensures they can operate efficiently even in high-volume applications.

6. Cleanroom Environments

In cleanroom environments, plastic multiflex chains are used to move products and materials between different stages of the production process. Their low particle generation and cleanliness make them ideal for applications where hygiene and contamination control are critical, while their flexibility ensures they can negotiate the tight spaces often found in cleanroom environments.

How Plastic Multiflex Chains Work

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

When selecting plastic multiflex chains for a particular application, several factors need to be considered:

  1. Load Capacity: The chain must be able to handle the weight and size of the products or materials being transported.
  2. Application Environment: The chain must be able to withstand the environmental conditions in which it will be used, such as temperature, humidity, and exposure to chemicals.
  3. Chain Material: The chain material must be compatible with the products or materials being transported and must meet any relevant industry standards.
  4. Chain Profile and Design: The chain profile and design must be suitable for the specific conveyor layout and requirements.
  5. Environmental Factors: The chain must be able to operate effectively in the specific environmental conditions of the application, such as cleanroom environments or outdoor settings.
  6. Conveyor System Layout: The chain must be able to operate effectively within the overall layout of the conveyor system, including any curves, inclines, or declines.
  7. Maintenance and Cleanability: The chain must be easy to maintain and clean, with minimal downtime required for cleaning and servicing.
  8. Cost Considerations: The chain must be cost-effective for the specific application and must provide a good return on investment.
  9. Supplier and Support: The supplier must be able to provide the necessary technical support and after-sales service to ensure the chain operates effectively over its lifespan.

Installation and Maintenance of Plastic Multiflex Chains


Proper installation of plastic multiflex chains is essential to ensure they operate effectively and efficiently. The installation process typically involves the following steps:

  1. Preparatory Steps: These include cleaning the conveyor track and ensuring all the necessary tools and equipment are available.
  2. Chain Assembly: The chain modules are assembled into the desired length and configuration.
  3. Sprocket Installation: The sprockets are installed onto the drive shaft and aligned with the chain modules.
  4. Tracking Adjustment: The chain is adjusted to ensure it tracks correctly along the conveyor path.


Regular maintenance is essential to ensure plastic multiflex chains operate effectively over their lifespan. The maintenance process typically involves the following steps:

  1. Regular Cleaning: The chain must be regularly cleaned to prevent the buildup of dirt, debris, and other contaminants that can impede its operation.
  2. Inspection: The chain must be inspected regularly for signs of wear and damage, such as broken modules or cracked hinges.
  3. Lubrication: The chain must be properly lubricated to ensure smooth operation and to prevent excessive wear and tear.
  4. Repair and Replacement: Any damaged or worn components must be repaired or replaced promptly to prevent further damage to the chain or the conveyor system.
  5. Training and Documentation: Operators and maintenance personnel must be properly trained in the operation and maintenance of the chain, and all maintenance activities must be properly documented to ensure compliance with industry standards and regulations.

Plastic Multiflex Chains and Sprockets

Our company also offers sprockets that are specifically designed to work with plastic multiflex chains. The sprockets engage with the tabs on the chain modules, propelling the chain forward and ensuring smooth and reliable operation. The close relationship between plastic multiflex chains and sprockets highlights the importance of selecting the right components for conveyor systems to ensure maximum efficiency and reliability.
