The engineering plastics of hardware machinery and equipment should not only meet the requirements of mechanical properties, wear resistance, self-lubrication, and convenient processing but also meet the requirements of low cost and good economy. PA and PA modified materials are the first choices. glass fiber reinforced is suitable for precision gears, bearings, flywheels, and sliding wear-resistant parts working under higher loads and temperatures.
The engineering plastic products of hardware machinery and equipment mainly include gears, bearings and bearing cages in mechanical transmission. of course, engineering plastics are also widely used in power tools, such as power tool housings, covers, handwheels, handles, fasteners, and pipe joints and other mechanical structures.
The engineering plastics of hardware machinery equipment are mainly divided into mechanical transmission devices and mechanical structural parts of electric tools. the mechanical transmission device has the characteristics of small friction factor, good wear resistance, good electrical insulation and corrosion resistance, easy processing, high productivity and low cost. the mechanical structure of electric tools should also have thermal conductivity and flame retardant.
