Metal belts are generally made from carbon steel or stainless steel which has been alloyed or treated depending on the application. Compared to plastic belts, metal belts are generally more expensive upfront, but it can offer better durability. Over time, a metal belts may develop deformations or curvature due to wear and tear. These deformations can be rectified through various methods such as shot peening to flatten out the cross curvature of deformed steel belts. This process can be performed on-site without interrupting production.The two main systems using metal belts are single-belt and double-belt systems. Single-belt systems are appropriate for manufacturing single-sided products such as pastilles, flakes, strips, and sheets. The double-belt system can manufacture the top and bottom of a product simultaneously, such as in chemical, rubber, laminate, and composite material processing operations.
Metal belts easily meet sanitation requirements
A recall is an enormous headache for those in the food manufacturing industry. Not only can it be extremely expensive, it can also do irreparable damage to a manufacturer's reputation. Metal belts are capable of withstanding the extremely high temperatures and pressure required for sanitation. An additional benefit to metal belts is that they are nonporous. Plastic belts are easily chipped and scratched which can become ideal locations for hazardous chemicals or bacteria.
Metal belts can withstand extreme temperature variation
In addition to sanitation, the heat resilience of metal gets extra points for functionality. Some applications of food processing will require cooking or cooling, and metal excels in both of these areas. A thermal expansion coefficient dictates how a material can expand, contract or otherwise change shape with temperature fluctuations. Most metals have a fairly low coefficient, meaning they retain heat when subjected to temperature change. Plastic can easily melt, warp or simply break during processes that metal will roll through easily.
Metal belts are less environmentally taxing
While virtually no manufacturing operation is without a carbon footprint, plastic is far more taxing on the environment to produce. Plastics are made from petroleum, which isn't exactly the poster child for sustainability. While the production of metal does result in pollutants, the sector has made strides in recent years.
Metal belts offer great flexibility
We don't literally mean the ability to flex, but rather, there is a metal solution for every pain point in food manufacturing. Metal conveyor belts generally have a greater ratio of open area which means they are ideal for baking, cooking, or any application where drainage is important. Furthermore, metal belts can be used effectively in conveyors with singular or multiple tight turns, which reduces the need for manual transferral to another belt.
Durability
Metal belts can withstand sustained exposure to extreme temperatures, hostile environments and vacuum environments. Engineers generally select a belt material based on physical properties, availability and cost, all of which can be adjusted by using a different combination of metal alloys.
No Lubrication
Unlike the links of a chain, a metal belt is a single element and, therefore, does not generate any component friction that requires lubrication. This reduces system maintenance, improves reliability and keeps conveyor systems clean.
