Once the rubber mixture is ready, it is processed using a series of machines designed for shaping and cutting. These machines include calendering machines, which flatten the rubber mixture into sheets, and extruders, which form rubber into specific shapes. The standard procedure often includes the reinforcement of the belts with fabrics such as polyester or nylon, which provide additional strength and durability. After the initial shaping, the belts are then cut to size, ready for the curing process.

Heavy duty serpentine belts are typically constructed from durable rubber with additional reinforcement. They often contain polyester cord for improved strength and flexibility, as well as a fabric cover to reduce noise and improve resistance to environmental factors, such as oil and heat. Some are further enhanced with special materials to provide better abrasion resistance and longevity, making them ideal for heavy-duty applications in trucks, construction equipment, and commercial vehicles.
