Are Plastic Multiflex Chains suitable for continuous high-speed production?

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. This lightweight nature allows for easier installation, reduced energy consumption, and improved overall efficiency.

2. Flexibility

Plastic multiflex chains offer exceptional flexibility, allowing them to conform to various conveyor layouts and adapt to changing production needs. This flexibility enables smooth product transfer and reduces the risk of jams or blockages.

3. High Strength

Despite their lightweight design, plastic multiflex chains boast impressive strength and load-bearing capabilities. They can withstand heavy loads and provide reliable and consistent performance in demanding applications.

4. Low Maintenance

Plastic multiflex chains require minimal maintenance compared to metal chains. They are resistant to corrosion, require no lubrication, and are easy to clean. This reduces downtime and maintenance costs.

5. Noise Reduction

Plastic multiflex chains operate with reduced noise levels compared to metal chains, creating a quieter and more comfortable working environment.

6. Chemical Resistance

Plastic multiflex chains are highly resistant to chemicals, making them suitable for industries that involve exposure to corrosive substances or harsh environments.

7. Cleanliness and Hygiene

Plastic multiflex chains are easy to clean and sanitize, making them ideal for industries that require strict hygiene standards, such as food processing or pharmaceutical manufacturing.

8. Energy Efficiency

Due to their lightweight and low-friction properties, plastic multiflex chains contribute to energy savings and reduced operating costs compared to heavier metal chains.

9. Versatility

Plastic multiflex chains can be customized to meet specific application requirements. They are available in various sizes, profiles, and configurations to accommodate different conveyor systems and product types.

Applications of Plastic Multiflex Chains

1. Conveyor Systems

Plastic multiflex chains are widely used in conveyor systems for industries such as automotive, packaging, and logistics. They facilitate the smooth movement of products along the production line.

2. Manufacturing and Assembly Lines

In manufacturing and assembly processes, plastic multiflex chains enable efficient material handling, ensuring seamless flow and high productivity.

3. Distribution and Warehousing

Plastic multiflex chains are suitable for distribution centers and warehouses, where they help optimize storage and enable the efficient movement of goods.

4. Packaging and Bottling

Plastic multiflex chains excel in packaging and bottling applications, providing reliable transportation of containers, packages, and bottles.

5. Material Sorting and Grading

Plastic multiflex chains are valuable in material sorting and grading systems, allowing for accurate and efficient separation of different materials based on size, shape, or quality.

6. Cleanroom Environments

Plastic multiflex chains are commonly used in cleanroom environments, where cleanliness, hygiene, and low particle generation are critical.

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.

How to Select Suitable Plastic Multiflex Chains

1. Load Capacity

Consider the maximum load the chain will need to support to ensure it can handle the weight without compromising performance.

2. Application Environment

Evaluate the operating conditions, including temperature, humidity, and exposure to chemicals or other potentially corrosive substances.

3. Chain Material

Select the appropriate plastic material (e.g., PE or PP) based on the application requirements and desired properties.

4. Chain Profile and Design

Choose the chain profile and design that best suits the conveyor system layout and the type of products or materials being conveyed.

5. Environmental Factors

Consider factors such as dust, debris, or extreme weather conditions that may affect the chain’s performance and durability.

6. Conveyor System Layout

Analyze the conveyor system layout to determine the required chain length, configuration, and any additional accessories or components.

7. Maintenance and Cleanability

Assess the chain’s ease of cleaning, maintenance requirements, and compatibility with cleaning agents or sanitizers.

8. Cost Considerations

Take into account the initial cost, long-term maintenance costs, and overall value for money when selecting plastic multiflex chains.

9. Supplier and Support

Choose a reputable supplier that offers technical support, customization options, and a reliable supply of spare parts or replacements.

Installation and Maintenance


1. Preparatory Steps

Prior to installation, ensure the conveyor system is properly prepared, including cleaning the tracks and ensuring proper alignment.

2. Chain Assembly

Assemble the plastic multiflex chain by interlocking the modules and connecting them securely using the provided connectors.

3. Sprocket Installation

Mount the sprockets or sprocket wheels onto the shafts, aligning them correctly with the chain’s tabs for proper engagement.

4. Tracking Adjustment

Adjust the tension and tracking of the chain to ensure smooth and accurate movement along the conveyor path.


1. Regular Cleaning

Regularly clean the chain to remove any accumulated debris or contaminants that may affect its performance.

2. Inspection

Periodically inspect the chain for signs of wear, damage, or misalignment, and address any issues promptly.

3. Lubrication

Apply appropriate lubrication to the sprockets or hinges, following the manufacturer’s recommendations.

4. Repair and Replacement

Replace any damaged or worn-out modules, connectors, or sprockets to maintain the chain’s integrity and performance.

5. Training and Documentation

Provide training to personnel responsible for chain maintenance and keep detailed documentation of maintenance activities and repairs.
