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. Here, we will discuss the various advantages, applications, working principles, selection criteria, installation and maintenance procedures of plastic multiflex chains.


1. Lightweight: Plastic multiflex chains are significantly lighter than traditional metal chains, making them ideal for applications where weight is a concern.

2. Flexibility: The modular design of plastic multiflex chains allows them to flex and articulate in multiple directions, making them ideal for applications that require flexibility.

3. High Strength: Though lightweight, plastic multiflex chains have high strength and load capacity, making them suitable for heavy-duty applications.

4. Low Maintenance: Due to their design, plastic multiflex chains require minimal maintenance, reducing overall maintenance cost.

5. Noise Reduction: Plastic multiflex chains generate less noise than metal chains, making them ideal for applications where noise is a concern.

6. Chemical Resistance: Plastic multiflex chains are resistant to chemicals used in cleaning processes, making them ideal for use in applications where cleaning is necessary.

7. Cleanliness and Hygiene: Plastic multiflex chains are easy to clean and maintain cleanliness, making them ideal for applications where hygiene is a concern.

8. Energy Efficiency: The low weight and friction of plastic multiflex chains lead to energy savings.

9. Versatility: Plastic multiflex chains are versatile and can be customized to suit specific application requirements.


1. Conveyor Systems: Plastic multiflex chains are widely used in conveyor systems for various industries, including food and beverage, healthcare, and automotive.

2. Manufacturing and Assembly Lines: Plastic multiflex chains can be used on manufacturing and assembly lines to convey products or parts.

3. Distribution and Warehousing: Plastic multiflex chains are used in distribution and warehousing to transport products from one point to another.

4. Packaging and Bottling: Plastic multiflex chains are used in packaging and bottling applications to transport products through the production line.

5. Material Sorting and Grading: Plastic multiflex chains are used in material sorting and grading applications to separate and sort products or materials.

6. Cleanroom Environments: Plastic multiflex chains are popular in cleanroom environments due to their suitability for use in sterile environments.

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.

Selection Criteria:

1. Load Capacity: The load capacity of the chain should match the application requirements.

2. Application Environment: The chain material should be suitable for the application environment, such as high or low temperature, chemical exposure, or corrosive environment.

3. Chain Material: The chain material should be selected based on the application requirements, such as high strength or flexibility.

4. Chain Profile and Design: The chain profile and design should match the conveyor layout and application requirements.

5. Environmental Factors: The environmental factors, such as humidity, temperature, and dust, should be considered when selecting the chain.

6. Conveyor System Layout: The conveyor system layout should be considered when selecting the chain, such as the number of curves and inclines.

7. Maintenance and Cleanability: The chain should be easy to maintain and clean.

8. Cost Considerations: The chain should be selected based on cost considerations.

9. Supplier and Support: The supplier should provide support for chain selection, customization, and maintenance.

Installation and Maintenance:


1. Preparatory Steps: The conveyor system should be prepared for chain installation, including cleaning and removing any debris.

2. Chain Assembly: The chain should be assembled according to the manufacturer’s instructions.

3. Sprocket Installation: The sprockets should be installed according to the manufacturer’s instructions.

4. Tracking Adjustment: The chain should be adjusted for proper tracking.


1. Regular Cleaning: The chain should be regularly cleaned to prevent the buildup of dirt or debris.

2. Inspection: The chain should be inspected regularly for signs of wear or damage.

3. Lubrication: The chain should be lubricated according to the manufacturer’s instructions.

4. Repair and Replacement: Any damaged or worn parts should be repaired or replaced immediately.

5. Training and Documentation: Operators should be trained on proper maintenance and documentation should be kept.
