Plastic Multiflex Chains for accurate conveyor belt tracking

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, resulting in reduced energy consumption and easier installation.

2. Flexibility

These chains can flex and articulate in multiple directions, allowing for smooth movement around corners and complex conveyor layouts.

3. High Strength

Despite their lightweight design, plastic multiflex chains exhibit excellent strength and durability, making them suitable for heavy-duty applications.

4. Low Maintenance

With self-lubricating properties and resistance to corrosion and wear, these chains require minimal maintenance, resulting in cost savings and increased operational efficiency.

5. Noise Reduction

Plastic multiflex chains produce less noise compared to metal chains, providing a quieter working environment.

6. Chemical Resistance

These chains are resistant to various chemicals, ensuring their durability and performance in challenging environments.

7. Cleanliness and Hygiene

Plastic multiflex chains are easy to clean and maintain hygiene standards, making them ideal for industries with strict cleanliness requirements.

8. Energy Efficiency

The lightweight and low-friction properties of these chains contribute to energy savings and reduced operating costs.

9. Versatility

Plastic multiflex chains can be customized to meet specific application requirements, offering versatility across various industries.

Applications of Plastic Multiflex Chains

1. Conveyor Systems

Plastic multiflex chains are widely used in conveyor systems for industries such as food and beverage, packaging, and automotive, ensuring efficient and reliable product transportation.

2. Manufacturing and Assembly Lines

These chains facilitate the smooth flow of products during manufacturing and assembly processes, improving productivity and reducing downtime.

3. Distribution and Warehousing

Plastic multiflex chains are essential for automated sorting, distribution, and warehousing systems, enabling efficient material handling and order fulfillment.

4. Packaging and Bottling

These chains ensure precise movement and positioning of packages and bottles in packaging and bottling lines, maintaining production efficiency.

5. Material Sorting and Grading

Plastic multiflex chains play a crucial role in material sorting and grading systems, allowing for accurate separation and classification of various materials.

6. Cleanroom Environments

These chains are ideal for cleanroom environments, where contamination control and hygiene are of utmost importance.

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

Consider the weight and size of the conveyed items to ensure the chain can handle the required load.

2. Application Environment

Evaluate the environmental conditions, such as temperature, humidity, and exposure to chemicals, to choose a chain with suitable material properties.

3. Chain Material

Select the appropriate plastic material, such as PE or PP, based on the specific application requirements.

4. Chain Profile and Design

Choose a chain design that aligns with the conveyor system layout and allows for smooth product transfer.

5. Environmental Factors

Consider factors like dust, debris, and moisture present in the working environment to ensure the chain’s longevity.

6. Conveyor System Layout

Take into account the conveyor layout, including the number of curves, inclines, and declines, to select a chain with appropriate flexibility and articulation capabilities.

7. Maintenance and Cleanability

Opt for a chain that is easy to clean and maintain, ensuring efficient operation and prolonging the chain’s lifespan.

8. Cost Considerations

Balance the chain’s cost with its performance and durability to make a cost-effective choice for your application.

9. Supplier and Support

Choose a reliable supplier who provides technical support and assistance with chain selection, installation, and maintenance.

Installation and Maintenance


1. Preparatory Steps: Ensure the conveyor system is properly prepared for chain installation.

2. Chain Assembly: Connect the modular units to form a continuous chain loop, following the manufacturer’s instructions.
