Selecting the right polycord requires both the understanding of your to-be-handled product, the environment in which the cord will work, and the various options available in the market today. In most cases, the application and the environment dictates the type of belt, although cost is also a compelling factor today.
Having a belt that does not serve your purpose can be very frustrating. For instance, it might break and hence cause downtime, which deteriorates productivity. In addition, repair and maintenance of belts can be very costly if it is being done all the time. Another aspect is safety of workers. A conveyor that is always breaking endangers the lives of workers, especially if installed overhead and is carrying heavy materials. It might also cause further losses if the material falls and breaks, or if its quality deteriorates because of a delay in the production process. This means you should not compromise on buying a belt of the required strength, thickness and size according to your applications.
Below is a guide on selecting a polyurethane belting solution depending on the type of application.
1.General purpose applications: General purpose applications are suited by general purpose belts, which are usually made of an inner carcass and an outer cover. This category includes the polycords made of rubber, PVC, Urethane, Neoprene, Nylon, Nitrile, Polyester, leather and other materials. These can be applied in high friction inclining and declining applications, low friction accumulation applications and oil resistant applications. Other areas of application include providing cut resistant, high temperature applications, bulk handling, and troughed for bulk handling.
For the case of polycords, ensure to ask whether the company does supply complete belts and which you might need instead of having to weld the parts yourself. This might require special tools and skill. You might also end up spending more money on the same.
2. Plastic belting and chains: These lightweight but durable and wear resistant polyurethane belting solutions are sold under various industry names including TableTop, MatTop, Angled Roller Belting and MicroSpan. They are applied in food production, packaging, pharmaceuticals, and manufacturing.
They can also be applied in inspection, die cast operations, packaging, stamping, high temperature applications, wet and dry operations.
3. Woven wire belting: This type is applied in food processing, washing, baking, dewatering, blanching, firing, decorating, cooking, freezing, enameling, pasteurizing and annealing. They are also used in thick film firing in electronics.
Other types include the Flat Wire Belting, which is considered economical than the woven wire belting and is applied in parts cleaning, painting and drying, product sorting, parts transfer, baking and freezing food.
In selecting a belt, ensure that you check how it will be cleaned and maintained. Ask about how it will be repaired in case of damage and how it will be replaced when it is completely damaged. Some belts can be cleaned, maintained and replaced but carry high maintenance costs than polyurethane belting solutions. Therefore, ensure that you compare the many available options in the market. Many people also worry about the cost and it depends on the types. While plastic could be cheaper than polycords, woven wire and metal belts could be more expensive.
