Cars are a common means of transportation in our lives, so what are the key points of making key fasteners for car engines? Please see me explain in detail next.
First, the structure of automobile fasteners
Automotive fasteners include a variety of standard and non-standard fastening elements that are fastened and attached throughout the vehicle. Bolts, screws, etc. are attached to the main body by screw tightening. Calculated by the number of parts, the proportion of fasteners in the total number of vehicle parts far exceeds that of any other parts, reaching 40% to 55%; the final assembly process and assembly of the vehicle mainly use fasteners to connect the parts Process; accidents and fatalities caused by some fastener failures also occur from time to time. Therefore, fasteners should be very important for the manufacture and use of automobiles, but in fact, automobile fasteners have not been widely and fully valued in China. This is a question worth discussing. Here, the author tries to make a preliminary discussion on this for reference only.
Second, the importance of automotive fasteners
Automotive Fastener Materiality Assessment To assess the importance of automotive fasteners or all automotive components, it is clear that a standard or guideline must first be established. There seems to be an inertial thinking in the auto industry that the more complex the technology and the more difficult it is to manufacture, the more important it is. For example, in the small automotive fastener industry, the term "high-strength fasteners" has been popular for many years and has been incorporated into national policy documents. Classic example. It is true that high-strength fasteners are often important fasteners, but it should also be said that this is not entirely the case. Obviously, this is a classification based on "manufacturer status". Since the only consumers of cars are people, the general public, the most reasonable and final principle should be the most reasonable and final principle to evaluate from the "user's point of view". The question is how to make this principle more concrete.
Production points of automobile fasteners
Effective management and control must be carried out in the whole process of design and manufacture of automobiles and parts. Obviously, this can only rely on centralized management departments such as automobile manufacturing, transportation, maintenance, and spare parts sales. Quality supervision, business administration and other departments work in coordination and from multiple perspectives. First manage the "safety part" as a focus. If the automotive industry incorporates it into the scope of product certification, production licenses, etc., gradually realize the production of licenses, and gradually prohibit the production of unlicensed and substandard "safety parts" within a certain period of time; the automotive industry and quality supervision departments will implement quality supervision and Inspection; industrial and commercial departments conduct circulation management of unlicensed and unqualified "security parts"; relevant management departments control and restrict the use of unlicensed and unqualified "safety parts" in the parts sales and maintenance industry... Wait. Obviously, the key is to control the origin of the product.
