The introduction of modern plastic modular belts about 40 years ago, greatly revolutionized conveyance systems and their popularity continues to soar. Made up of hinge rods and injection-moulded plastic modules that are positively driven, they have been transforming the conveyance process.
Users find modular plastic belts more convenient and superior when compared to the conventional belt conveyors. This is especially the case for sectors with heavier loads and high volumes to be handled.
Here are a few factors that contribute to the popularity of plastic modular belts:
They are ideal for areas that require a high standard sterilization and cleanliness, like pharmaceuticals and the food industry. They are easier to clean and sanitize than many other alternatives and are also perfect for reducing bacteria retention and standing liquids. Plastic is cheaper than other materials like fiberglass and stainless steel which offer the same benefits when used for the conveyor systems.
Modular plastic belts are more durable than the fabric conveyor belts, are capable of handling larger load capacities and work better under harsh conditions.
The tracking drive using hinge rods, plastic belts, and sprockets make it ideal to handle heavier loads with speed. The positive drive and the tracking ensure that there is no slippage, minimizing damage to the edge of the belt.
The injection-molded modules feature many different surface structures, the most common 3 types being PE (polyethylene), PP (polypropylene) and the POM (Acetal). These plastic types are readily available, and each has its own unique characteristics suitable for the smooth function of the conveyor belt. They have the strength, temperature resistance, hardness, density and are friction coefficient.
The design for modular belting is either open hinged or closed hinged. Your requirements and product type will determine your choice. The open hinged is specifically designed for cases where sanitation is critical, while closed hinged is ideal for handling materials and other highly loaded applications other than food.
You need only to replace the damaged plastic segments of the plastic modular belt, unlike the belt conveyors that require full replacement.
Areas of application
Plastic modular belts are best suited to industries that handle high volumes, heavy loads and/or sensitive products requiring high standards of cleanliness and sanitation. These include food processing, construction, automotive, agricultural, forestry (wood movement), industrial, pharmaceuticals, packaging and material handling, shipping and clearing, as well as recycling sectors.
