Modern technology has given us the ability to produce parts quickly, allowing rapid development of prototype car production. To achieve this speed, manufacturers of prototype parts use a variety of advanced technologies that combine the vision of the designer with the efficiency of the computer-controlled process.
Worldwide, the gold standard for automotive prototype parts manufacturing is computer numerical control (CNC) machining. There are many types of machine tools that support CNC machining, such as milling machines, lathes, plasma cutting machines, laser cutting and discharge.
CNC machines can produce items either very quickly (as in the prototyping process) or very accurately, as in the final production concept. CNC machine tools can work in a variety of media, including plastics, metals and even metal raw materials.
Urethane Vacuum Casting
Polyurethane vacuum casting utilizes silicone molds and does not require complex tools such as injection molding or CNC machine tools.
Although it is very fast, it is also slightly more expensive than other types of production processes, so it is more ideal for short runs or ultimately suitable for and complete type of work before mass production. The technology is growing in popularity.
Injection molding allows manufacturers to produce a large number of parts with extremely high accuracy and a low degree of failure. This process infuses the melted material into a mold that has been meticulously machined to a precise level.
This mold is expensive to create in front, so it is not ideal if only short production runs are needed. In fact, this is where polyurethane injection molding makes more sense. If a larger production run is planned, for example a production “mule” or test car is needed, then an injection mold may be invoked.
3D printing (SLA or SLS) is a production process that uses very thin strips of material in order to create a three-dimensional object. This allows everyone from hobbyists to prototype car companies to create fully customised parts almost out of thin air. No moulds are required, the only limits are your imagination and the size of your machine!
