How are cars created?
2 Answers
The manufacturing process of automobiles is mainly divided into: stamping, welding, painting, assembly, and inspection. The following is the manufacturing process: 1. Stamping: Stamping is the first step in automobile manufacturing, where metal sheets are processed into parts of specific shapes using specialized molds. 2. Welding: The main welding assemblies include: the engine compartment assembly, floor assembly, side panel assembly, front and rear door assemblies, tailgate assembly, and hood assembly. 3. Painting: The white body from the welding workshop enters the painting workshop, where it undergoes three main processes: electrocoating, mid-coating, and top-coating. 4. Assembly: Various components such as wiring harnesses, doors, airbags, ECUs, dashboards, engines, front and rear axles, tires, and other interior, exterior, and electronic parts are installed. Fluids such as fuel, lubricating oil, cleaning agents, coolant, brake fluid, and antifreeze are also filled during this process. 5. Inspection: The main inspection items include: four-wheel alignment inspection, headlight inspection, braking performance inspection, emission inspection, shower inspection, and road inspection.
In my exploration of automotive history, I discovered that the creation of cars began in the late 19th century. Back then, engineers sought to revolutionize transportation, replacing sluggish horse-drawn carriages. Karl Benz built the first internal combustion engine tricycle in 1885, which resembled an oversized bicycle with an engine. But that alone wasn't enough—Henry Ford later invented the assembly line production model, making mass manufacturing of cars possible and reducing costs so that ordinary people could afford them. There were many details along the way: engines evolved from steam to gasoline-powered internal combustion, wheels were fitted with rubber tires for shock absorption, and body materials shifted from wood to metal for increased durability. Societal needs also drove these changes—the Industrial Revolution spurred urban expansion, and people demanded greater speed. Without these inventors making incremental improvements, our dream of driving on highways would still be far off.
