Plastic Multiflex Chains for Sanitary Food Processing

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 lightweight, allowing for easy installation and reduced energy consumption.

2. Flexibility

These chains offer exceptional flexibility, enabling them to adapt to various conveyor layouts and accommodate curved paths.

3. High Strength

Despite their lightweight design, plastic multiflex chains possess high tensile strength, ensuring reliable performance under heavy loads.

4. Low Maintenance

With their self-lubricating properties and resistance to wear and corrosion, these chains require minimal maintenance, reducing downtime and operational costs.

5. Noise Reduction

The use of plastic materials helps dampen noise generated during operation, contributing to a quieter and more comfortable working environment.

6. Chemical Resistance

Plastic multiflex chains offer excellent resistance to chemicals, making them ideal for applications involving exposure to corrosive substances.

7. Cleanliness and Hygiene

These chains are easy to clean and sanitize, meeting the strict hygiene requirements of sanitary food processing environments.

8. Energy Efficiency

Due to their low friction properties, plastic multiflex chains contribute to energy savings and increased overall efficiency.

9. Versatility

Plastic multiflex chains can be customized to meet specific requirements, allowing for seamless integration into a wide range of applications.


1. Conveyor Systems

Plastic multiflex chains are widely used in conveyor systems to transport various products and materials across different industries.

2. Manufacturing and Assembly Lines

These chains are essential components in manufacturing and assembly lines, ensuring smooth and efficient production processes.

3. Distribution and Warehousing

In distribution centers and warehouses, plastic multiflex chains enable the seamless movement of goods and optimize storage operations.

4. Packaging and Bottling

These chains play a crucial role in packaging and bottling applications, facilitating the efficient packaging and labeling of products.

5. Material Sorting and Grading

Plastic multiflex chains are used in material sorting and grading systems, enabling accurate and reliable product classification.

6. Cleanroom Environments

The cleanliness and chemical resistance of plastic multiflex chains make them ideal for use in cleanroom environments, such as those found in pharmaceutical or electronic industries.

Working Principle

Plastic Multiflex Chains operates 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.

Choosing the Right Plastic Multiflex Chains

1. Load Capacity

The load capacity of the chain should be carefully considered to ensure it can withstand the weight of the materials being conveyed.

2. Application Environment

Factors such as temperature, humidity, and exposure to chemicals or abrasive materials should be taken into account when selecting the appropriate chain.

3. Chain Material

The choice of chain material depends on the specific application requirements, considering factors such as strength, flexibility, and chemical resistance.

4. Chain Profile and Design

The profile and design of the chain should align with the conveyor layout and the type of products or materials being transported.

5. Environmental Factors

Considerations should be given to the operating conditions, such as ambient temperature, moisture levels, and the presence of dust or debris.

6. Conveyor System Layout

The layout and configuration of the conveyor system will influence the chain’s length, width, and overall design.

7. Maintenance and Cleanability

It is important to select a chain that is easy to clean and maintain, ensuring the highest standards of hygiene and compliance.

8. Cost Considerations

The cost-effectiveness of the chain, including its initial purchase cost and long-term maintenance expenses, should be taken into account.

9. Supplier and Support

Choosing a reliable supplier who can provide technical support and assistance is crucial for a successful installation and long-term performance of the chain.

Installation and Maintenance


1. Preparatory Steps: Ensure the conveyor system is properly prepared and all necessary tools and equipment are available.

2. Chain Assembly: Connect the individual chain modules together, ensuring proper alignment and interlocking.

3. Sprocket Installation: Install the sprockets or sprocket wheels at the appropriate positions, engaging with the chain modules.

4. Tracking Adjustment: Adjust the chain’s tracking to ensure it remains aligned and centered on the conveyor path.


1. Regular Cleaning: Remove any dirt, debris, or product residue from the chain to maintain optimal performance and hygiene.

2. Inspection: Regularly inspect the chain for any signs of wear, damage, or misalignment that may require repair or replacement.

3. Lubrication: Apply a suitable lubricant to reduce friction and ensure smooth movement of the chain.

4. Repair and Replacement: If any components of the chain are damaged or worn out, they should be promptly repaired or replaced to prevent further issues.

5. Training and Documentation: Provide proper training to operators on maintenance procedures and keep detailed documentation for reference.

Sprockets and Their Importance

In conjunction with plastic multiflex chains, sprockets play a crucial role in the efficient operation of the conveyor system. Sprockets are toothed wheels that engage with the tabs on the chain modules, propelling the chain forward. The correct design and sizing of the sprockets are essential to ensure smooth movement and minimize wear on both the chain and the sprockets. Proper alignment and engagement between the sprockets and the chain modules guarantee optimal performance and extended service life.
