The "Automobile (Prototype)" category refers to the creation of prototypes for design verification, functional evaluation, and performance confirmation during the development of new vehicles and parts. This is an indispensable process for ensuring quality and performance and for productivity considerations prior to mass production. Key applications are diverse, including design confirmation, component fitment verification, various tests such as strength, durability, and NVH, and preliminary studies of manufacturing methods. Typical services include high-precision machining, manufacturing of resin and metal parts using 3D printing (AM), sheet metal and resin molding using simple molds, vacuum casting, welding and joining, surface treatment, and prototype evaluation in conjunction with CAE analysis. Short lead times and high precision are required, and integration with digital technologies is progressing.
