Uses of Plastic Chains in Clean and Corrosion-Resistant Conveyor Systems
Publish Date: November 3, 2025
Plastic chains have become a key component in modern conveyor systems that demand cleanliness, corrosion resistance, and low maintenance. Unlike metal chains, plastic chains are lightweight, non-corrosive, and resistant to chemical and moisture exposure, making them ideal for industries like food processing, pharmaceuticals, packaging, and electronics.
This article explores the major uses and benefits of plastic chains in conveyor systems designed for hygienic and corrosion-resistant environments.
Why Choose Plastic Chains?
Plastic conveyor chains are engineered using materials like polyacetal (POM), polypropylene (PP), and polyethylene (PE). These materials offer excellent resistance to moisture, chemicals, and cleaning agents, which makes them ideal for applications requiring hygiene and durability. In addition, plastic chains operate quietly and require minimal lubrication compared to metal alternatives.
Their modular design also allows for easy maintenance and replacement, enhancing operational uptime and reducing long-term costs.
Applications of Plastic Chains in Clean and Corrosion-Resistant Conveyors
- Food Processing Conveyors: Plastic chains are widely used for transporting bakery goods, dairy products, and beverages. Their non-porous surfaces prevent bacterial growth and allow for easy sanitation during washdowns.
- Pharmaceutical and Medical Equipment Lines: In cleanroom environments, plastic chains help maintain product purity and reduce the risk of contamination due to their non-reactive and dust-free properties.
- Chemical and Laboratory Systems: Plastic chains resist chemical corrosion from acids, solvents, and cleaning solutions, making them suitable for harsh industrial environments.
- Packaging and Bottling Lines: Their smooth and quiet operation ensures safe product transfer, even with fragile bottles, cartons, or containers.
- Electronics Manufacturing: Used in static-free transport systems, plastic chains prevent electrostatic discharge and protect delicate components.
Material Options and Their Advantages
| Material Type | Properties | Common Applications |
|---|---|---|
| Polyacetal (POM) | High strength, wear-resistant, and suitable for precision movement. | Food packaging and bottling conveyors. |
| Polypropylene (PP) | Resistant to chemicals and high-temperature cleaning agents. | Pharmaceutical and chemical conveyors. |
| Polyethylene (PE) | Lightweight, flexible, and impact-resistant. | Light-load and curved conveyor systems. |
Benefits of Using Plastic Chains
- Corrosion Resistance: Unaffected by water, steam, and cleaning agents, making them ideal for wet or humid environments.
- Hygienic Design: Smooth, non-stick surfaces minimize residue buildup and allow for easy cleaning.
- Low Noise Operation: Plastic chains produce less vibration and noise compared to metal chains.
- Reduced Maintenance: Require minimal lubrication and are easy to replace due to modular design.
- Energy Efficiency: Lightweight materials reduce the load on drive motors, improving energy efficiency.
Design Considerations for Plastic Chain Conveyors
When designing a conveyor system with plastic chains, it is important to consider factors such as:
- Load-carrying capacity and chain width based on product size and weight.
- Chain pitch and material compatibility with environmental conditions.
- Proper sprocket design to ensure smooth engagement and minimize wear.
- Ease of disassembly for routine cleaning and maintenance.
By incorporating these design considerations, engineers can build conveyor systems that meet hygiene and performance standards while maintaining operational efficiency.
Conclusion
Plastic chains offer a clean, corrosion-resistant, and cost-effective solution for conveyor systems in industries where hygiene, durability, and low maintenance are priorities. Whether used in food, pharmaceutical, chemical, or electronics applications, these chains provide smooth and reliable product movement with minimal wear and noise. By selecting the right material and design, plastic chain conveyors can significantly improve system performance and reduce downtime, making them a smart investment for modern production environments.
