　　Car fixture is according to the requirements when the model is specialized in planning and design and development, professional car fixture available check out his size, size to measure and evaluation, it is mainly used for production preparation period determination and adjustment of precision tooling and mass production after the size of the daily management.

　　Car fixture in the main body is the main framework of fixture, including fixture base (datum), decent and installation department, in general, decent epoxy resin or use the aluminum base and car.

　　Due to request mold body installation department must be able to withstand the body strength 12 n · m (122 KGF · cm) above the cyclotron. So, when the material selection of the subject of resin material, should be made of metal parts, etc into installation of lamps and lanterns, in order to prevent the lamps and lanterns when loading and unloading fall off easily and maneuver, and so on and so forth.
