Belt drive is a combination of belt and pulley that facilitates freight transfer between the shafts. Other major applications of belt drives include clutching, power transmission, and synchronization of shafts. The global industrial belt drives market is fueled by the growing need to automate processes in both discrete and process industries. Therefore, belt drives have become an essential part of several industries as they ensure a robust and reliable industrial operations for several applications, ranging from conveyor systems to heavy-duty power transmission.

Injection molding is the most commonly used manufacturing process for the fabrication of plastic parts. Injection molding is used to manufacture a wide variety of products, which vary considerably in their dimensions, complex structures, and end-use applications. The injection molding is done by an injection molding machine and requires plastic and the typical raw material, and a shaping mold. The molding machine melts the plastic, which is then injected into the mold, where it cools and solidifies into the final part.

CFRPs are high-strength and lightweight composite materials that contain a matrix, which is generally a polymer resin, and carbon fiber, a reinforcement material. Epoxy is the most commonly used polymer resin for manufacturing CFRPs. However, other polymers such as polyester, vinyl ester, or nylon are also used as reinforcement matrices. The properties of these plastics depend on the structure of the carbon fiber and that of the binding matrix (resin) material. Silica, rubber, and nanotubes are also used for reinforcement. The reinforcing phase is either in continuous or discontinuous form.
