Now all industries are struggling to find ways to reduce costs. Some valve industry bosses find that valve design costs have a greater impact on their overall cost when reducing costs. So the design cost of the valve will affect the overall cost of the valve?

  The impact of design factors on cost is mainly reflected in the following aspects:

  1. Functional rationality of design products


  The functional rationality of the designed product will affect the product's manufacturing cost and market reputation, and affect the product's potential market. It is the most reasonable design to design a product that can meet user requirements and minimize its own cost. Therefore, as a valve designer, it is necessary to collect user data extensively, carefully conduct statistics and analysis, and then determine the basic types of valves with complete functions and certain certain improvements as the final products of the series of valves.

  This type can meet the requirements of most users, and for those users who require higher performance and more complete functions, we can make simple changes and combinations on the basis of this basic type to meet their requirements. Such a product is a reasonable design, and only then can the cost be minimized.

  2. The structural rationality of the designed product


  The structural rationality of the designed product will affect the weight of the blank and the manufacturability of the product, which in turn affects the raw material procurement cost and process cost. For valve designers, "weight reduction and enhancement" is an eternal pursuit.

  For a special pressure vessel such as a valve, due to the complexity of its structure and shape, due to the uncertainty and instability of the actual pressure, due to the uncertainty of its actual bearing capacity on the engineering pipeline, due to the physical nature of the main material 1. The instability of chemical properties, due to the lack of corrosion data of various materials under different media and pressures, so far there is no complete set of mechanics (strength, stiffness) calculation theory, which can meet the performance of the product Minimize product weight.

  However, with the advancement of science, the development of material science and mechanical theory, especially the application of computer technology in the field of material mechanics, our computing power for materials is gradually improving, how to better design a more reasonable structure and a more reasonable shape The products with more reasonable weight will be the efforts of every valve designer.

  3. The rationality of the design process


  The technological rationality of the designed product will affect the rationality of the processing technology and affect the processing cost. The structure of products and parts is simple and complex, the design of the processing surface, the design of the matching accuracy, and the design of the assembly form will all affect the production of the model, the molding of the blank, the difficulty of the processing process, the amount of processing and the number of processing hours, assembly The difficulty of painting, painting and packaging and transportation, etc. Therefore, when designing, a designer's craft experience is extremely important.

  As a qualified designer, not only must have the design, calculation ability, but also have a wealth of process knowledge, familiar with the entire production process of their products. Whether it is the model making of castings, casting molding, annealing treatment, blank blanking of forgings, stamping forming, welding forming of welded parts, post-welding treatment, or the machining methods and procedures of all parts, assembly test process, and various standards The size and performance of the parts must be sufficiently understood. In this way, we can apply our own process experience to the actual design, so as to avoid the waste of product design in process.

  4. The appearance of the designed product is reasonable


  The rationality of the appearance of the designed product will affect the market volume of the product, and then affect the batch cost. A popular saying in the mechanical design industry is that "ugly is unreasonable". That is to say, if the shape of the product we designed is not good-looking, there must be some unreasonable aspects in rigidity and strength. If the unreasonable shape needs to achieve the required strength and performance, it must be achieved by adding materials. Therefore, a reasonable shape design not only looks good, but also saves materials and reduces costs.

  Therefore, users choose products of a certain company according to their appearance, they must not simply say that they only look at the appearance but not the essence. It is also based on these considerations that the product packaging has always been striving to achieve beautiful appearance, beautiful appearance, and good packaging. Because once such a product passes the trial, it is easy to form a batch order, and if a product can form a mass production, its model utilization rate, material utilization rate, process fluency, and management costs will be greatly reduced.
