Plastic Multiflex Chains for Conveyor Belt Alignment

Plastic Multiflex Chains for Conveyor Belt Alignment

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.


  1. Lightweight: Due to their plastic construction, multiflex chains are significantly lighter in weight than traditional metal chains, which can reduce energy consumption and increase efficiency.
  2. Flexibility: Multiflex chains are highly flexible and can articulate in multiple directions, making them well-suited for conveying products around corners or in curved conveyor paths.
  3. High Strength: Despite their lightweight design, multiflex chains are incredibly strong and can reliably support heavy loads without breaking or failing.
  4. Low Maintenance: Multiflex chains require minimal maintenance and can operate for extended periods without lubrication or servicing.
  5. Noise Reduction: Compared to metal chains, plastic multiflex chains operate with significantly less noise, which can improve workplace safety and reduce noise pollution.
  6. Chemical Resistance: Multiflex chains are resistant to a wide range of chemicals and can withstand exposure to harsh or corrosive substances without degrading or breaking down.
  7. Cleanliness and Hygiene: Due to their plastic construction, multiflex chains are highly resistant to bacteria and other contaminants, making them ideal for use in cleanroom or food handling environments.
  8. Energy Efficiency: Due to their lightweight and low friction design, multiflex chains can significantly reduce energy consumption and operating costs.
  9. Versatility: Multiflex chains can be easily customized to suit specific conveyor layouts and requirements, and can be used in a wide range of applications and industries.


Multiflex chains are suitable for a wide range of applications, including:

  1. Conveyor Systems: Multiflex chains are commonly used in conveyor systems to transport products or materials from one point to another.
  2. Manufacturing and Assembly Lines: Multiflex chains are often used in manufacturing or assembly lines to move products through various stages of production.
  3. Distribution and Warehousing: Multiflex chains are used in distribution and warehousing applications to sort and transport products to different areas of the warehouse.
  4. Packaging and Bottling: Multiflex chains are commonly used in packaging and bottling applications to transport products to packaging machines or bottling lines.
  5. Material Sorting and Grading: Multiflex chains can be used in material sorting and grading applications to separate and sort materials based on size or other characteristics.
  6. Cleanroom Environments: Multiflex chains are ideal for use in cleanroom environments due to their resistance to bacteria and other contaminants.

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.

How to Select the Right Plastic Multiflex Chains

  1. Load Capacity: Determine the maximum load capacity required for your application to ensure that the chain can reliably support the weight of your products or materials.
  2. Application Environment: Consider the temperature, humidity, and other environmental factors that may affect the performance of the chain in your specific application.
  3. Chain Material: Choose the appropriate chain material based on the chemical resistance, temperature tolerance, and other properties required for your application.
  4. Chain Profile and Design: Select the chain profile and design that best suits your conveyor layout and requirements.
  5. Environmental Factors: Consider the impact of dust, debris, and other environmental factors on the performance and longevity of the chain.
  6. Conveyor System Layout: Consider the layout and configuration of your conveyor system to ensure that the chain can be easily assembled, disassembled, and maintained.
  7. Maintenance and Cleanability: Choose a chain that is easy to clean and maintain to minimize downtime and ensure optimal performance.
  8. Cost Considerations: Consider the upfront and long-term costs associated with the chain, including purchasing, installation, and maintenance.
  9. Supplier and Support: Choose a reputable supplier that can provide technical support, training, and documentation to ensure the best possible performance and longevity of the chain.

Installation and Maintenance


  1. Preparatory Steps: Before assembling the chain, ensure that all parts are clean and free of dirt or debris.
  2. Chain Assembly: Assemble the chain according to the manufacturer’s instructions, ensuring that all links are securely connected.
  3. Sprocket Installation: Install the sprockets onto the conveyor system, ensuring that they are properly aligned and adjusted.
  4. Tracking Adjustment: Adjust the tracking of the chain to ensure that it runs smoothly and does not derail.


  1. Regular Cleaning: Clean the chain regularly to remove dirt, debris, and other contaminants that can cause wear and tear.
  2. Inspection: Inspect the chain regularly for signs of wear, damage, or other issues that may affect its performance.
  3. Lubrication: Lubricate the chain as needed to reduce friction and prevent wear and tear.
  4. Repair and Replacement: Repair or replace any damaged or worn parts to ensure optimal performance and longevity.
  5. Training and Documentation: Provide training and documentation to operators and maintenance personnel to ensure that the chain is properly maintained and serviced.
