The high manufacturing cost of fixture is due to the production of single order, which has the characteristics of high manufacturing accuracy and difficult design. Complex fixture design and programming design is only used for single order production, can not form a large amount of quantitative production. According to statistics, the cost of design, programming and tool changing for fixture orders exceeds 50% of the fixture manufacturing cost. If the use of mass production, manufacturing costs are reduced, huge space for development. The design and development of automobile testing tools need high quality and creative engineering and technical personnel, and the manufacturing of testing tools needs workers with high operating experience and skill proficiency. However, inspection projects are not continuous, inspection enterprises often face the problem of working overtime for more projects, and no work for less projects.

    Automobile testing equipment enterprises should establish professional industrial chain alliances through professional integration, and adopt more standard parts in the design of testing equipment to avoid problems such as high proportion of designers and programmers, low per capita output value and increased cost load brought by independent design and manufacturing of each company.

    The cost of inspection materials is an important part of the total cost, accounting for about 30% of the total cost. At present, China's car service life is short, 5 years for new replacement, 2 years for internal and external modification, 1 year for exterior modification. The service life of inspection tools is short, especially internal and external tools. After the completion of the project, the accuracy of the fixture remains good, but it cannot be reused and can only be used as waste.

    At present, the commonly used detection tools are cast aluminum, aluminum profiles, cast steel, stainless steel, steel profiles, wood and so on. In addition to the wood substitute, the other materials have the condition of dimensional stability and repeated recycling, especially the bottom plate and support structure of the fixture is very valuable.

    Forms such as recycling are also important for thinking about benign development conditions.
