Nowadays, every industry is trying to find ways to reduce costs. Some owners of valve industry find that the cost of valve design has a greater impact on their overall cost when they reduce costs. So how does the design cost of the valve affect the overall cost of the valve?
_. The influence of design factors on cost is mainly manifested in the following aspects:
1. Functional Rationality of Designed Products
_. The functional rationality of the designed product will affect the manufacturing cost and market reputation of the product and the potential market of the product. It is the most reasonable design to design a product that can not only meet the user's requirements, but also reduce its own cost to the lowest level. Therefore, as a valve designer, it is necessary to collect extensive user data, conduct careful statistics and analysis, and then determine that the basic types of valves with basic functions and certain improvements are used as the final products of this series of valves.
_This type can meet the requirements of most users, but for those users who require higher performance and more complete functions, we can make simple changes and combinations to meet their requirements on the basis of this basic type. Such a product is a reasonable design, in order to really reasonable to reduce the cost to the lowest.
2. Rationality of the structure of the designed product
_The rationality of product structure will affect the weight of the blank and the technological properties of the product, and then affect the purchase cost of raw materials and process costs. For valve designers, "weight loss and enhancement" is an eternal pursuit.
_For valve, a special pressure vessel, due to its complexity of structure and shape, uncertainty and instability of actual pressure, uncertainty of actual bearing capacity in engineering pipeline, instability of physical and chemical properties of main material and lack of various materials in different media. Corrosion data under quality and pressure make up for the lack of a complete set of mechanics (strength, stiffness) calculation theory so far, which can not only meet the performance of the product, but also make the weight of the product the lowest.
However, with the progress of science, the development of material science and mechanics theory, especially the application of computer technology in the field of material mechanics, our ability to calculate materials is gradually improving. How to better design products with more reasonable structure, more reasonable shape and more reasonable weight will be every valve. The direction of door designer's efforts.
_3. Process rationality of product design
_The rationality of the process of designing products will affect the rationality of the processing technology and the processing cost. The structure of products and components is simple and complex, the design of processing surface, the design of matching precision and the design of assembly form all affect the manufacture of models, the forming of blanks, the difficulty of processing technology, the amount of processing time, the difficulty of assembly, the difficulty of painting and packaging transportation, etc. Therefore, in the design, a designer's process experience is very important.
As a qualified designer, we should not only have the ability of design and calculation, but also have abundant technological knowledge, and be familiar with the whole production process of our products. Whether it is the casting model making, casting, annealing, blanking, stamping, welding, post-processing, or all parts of the mechanical processing methods and processes, assembly test process, as well as the size and performance of various standard parts, we should have a sufficient understanding. Only in this way can we apply our own process experience to the actual design, thus avoiding the waste of product design in the process.
4. Appearance Rationality of Designed Products
_. The appearance rationality of the designed product will affect the market batch of the product, and then affect the batch cost. A popular saying in the mechanical design industry is "ugly is unreasonable". That is to say, if we design the product shape is not good, there must be unreasonable in stiffness and strength. The unreasonable shape, in order to achieve the required strength and meet the performance, must depend on increasing the material to achieve. Therefore, reasonable shape design, not only looks good, but also can save materials and reduce costs.
_Therefore, users can not simply say that they only look at the appearance but not the essence when they choose the products of an enterprise according to their appearance. It is also based on these considerations that the packaging of the products has been striving to achieve beautiful appearance, beautiful appearance and good packaging. Because once such products pass the trial, it is easy to form a batch order, and if a product can form a batch production, its model utilization rate, material utilization rate, process fluency, management costs will be greatly reduced.
5. Quality Rationality of Designed Products
_. The rationality of product quality will affect the cost of product sales, especially after-sales service. The quality of products not only determines the life of a product, but also determines the credibility, survival and development of an enterprise. For many users, the quality of products is the most comprehensive performance, the best quality of materials, the best quality, the lowest price. For our valve manufacturers, while we are pursuing quality and reliability, we are more concerned about how to minimize the cost of products. As a designer, it is necessary to find a balance point between user's needs and enterprise's pursuit from the design point of view, so that the interests of both sides can reasonably get the maximum dimension.
