Plastic modular conveyor belt manufacturer

Plastic modular conveyor belts are conveyor belts assembled from injection-molded plastic modules through interlocking hinge pins. They are commonly used in the food, beverage, packaging, and chemical industries. Prices vary significantly depending on the material, specifications, and brand, and are typically priced per meter, square meter, or as a whole belt.

Common Materials and Specifications: How to Choose

1. Common Materials: Engineering plastics such as PP (polypropylene), PE (polyethylene), POM (polyoxymethylene), and nylon. These are oil-resistant, water-resistant, and corrosion-resistant, and some meet food contact standards.
2. Main Specifications: Common pitches include 12.7mm, 19.05mm, 25.4mm, 38.1mm, and 50.8mm. Open area ratios can be selected from 2% to 48%, forming flat, grid, perforated, and ribbed surface structures.
3. Applicable Temperature: Most can operate from -50℃ to approximately 100℃. Materials such as POM have even higher temperature resistance, and some high-temperature models can adapt to environments above 120℃.
4. How to determine the most suitable material: For scenarios with high hygiene requirements, such as food and pharmaceutical industries, prioritize non-porous, easy-to-clean, and hygiene-compliant modular conveyors; for heavy-duty applications, sharp workpieces, or corrosive environments, consider POM or nylon materials; for light-duty, general conveying, PP or PE materials are suitable.

Common Applications:

1. Food and Beverage: Seafood processing, frozen food, beverage bottling, fruit and vegetable grading, slaughtering and cutting, etc. Advantages include resistance to dirt accumulation, water and oil resistance, and easy cleaning.
2. Packaging and Logistics: Carton, bottle, and pallet conveying; supports straight, turning, incline, and spiral conveying combinations.
3. Chemical and Pharmaceutical: Resistant to corrosive environments, dry or humid conditions; some models meet FDA, USDA, and other hygiene certification requirements.
4. Electronics and Automotive: Light-duty assembly lines and component conveying; lightweight and low-noise plastic modular conveyors are suitable for workstations with high cleanliness requirements.

How to Get Quotes and Find Suppliers

1. Significant Price Differences: Market quotes typically range from tens to thousands of yuan per meter, depending on the material, pitch, width, thickness, customization, and brand. Preliminary prices should not be used as the sole basis for purchasing decisions.
2. When requesting a quote, clarify these parameters: conveyor belt material, pitch, width, length, operating temperature, whether baffles or side plates are needed, whether it is food-grade, and frame matching requirements. The more specific the parameters, the more accurate the quote.
3. When selecting a supplier, consider these factors: whether they have relevant industry case studies, whether they can provide material testing reports or hygiene certifications, whether they support non-standard customization, delivery time, and after-sales response capabilities. Request samples for testing if necessary.
4. Verify Information Carefully: Some quotes come from commercial platforms or distributors, and prices fluctuate with the market. Before contacting the manufacturer, it is recommended to confirm the latest quote and supply status.

Working Principle

The modular plastic conveyor belt operates based on its unique modular structure and sprocket drive system. Its transmission method utilizes precise sprocket drive and traction, effectively preventing belt stretching, slippage, serpentine movement, and misalignment.

The conveyor belt is assembled from injection-molded plastic modules using plastic hinge pins extending across its entire width in a “brick-and-mortar” or interlocking manner. The chain ends of adjacent module rows are staggered and connected by pins. This design fundamentally improves the overall strength of the conveyor belt and allows for assembly into any desired width and length.

Baffles and side plates can also be interlocked using hinge pins, becoming integral components of the conveyor belt. During turns, the inner modules achieve tight contraction through a special overlapping design of the high and low chain ends.

This modular structure makes maintenance, repair, and partial replacement very convenient, eliminating the need for specialized vulcanization or splicing equipment and significantly reducing downtime. The sprocket drive system allows for longer conveyor belt runs, thereby reducing the number of drive mechanisms and motors and improving energy efficiency. The engineering plastics used in the conveyor belt (such as PP, PE, POM, nylon, etc.) give it the characteristics of being oil-resistant, water-resistant, and resistant to cutting and impact.
