Profit=sales revenue, cost, tax, and related management expenses. It can be seen that under a certain sales revenue, only by reducing costs, taxes, and related management expenses can profit be increased. Among them, taxes cannot be reduced, and the reduction of related management expenses is achieved through the good operation of the enterprise's quality management system. The article explores the feasibility of improving product profits by reducing costs. Of course, the prerequisite for reducing costs is to maintain the quality level of the product.
The cost mainly consists of raw material costs and manufacturing costs, including production equipment costs, human resource costs during the production process, etc. Equipment investment is necessary, and workers' wages cannot be arbitrarily reduced. It can be seen that the reduction in manufacturing costs is limited, so we can only find ways to reduce raw material costs. However, reducing raw material costs cannot lower the level of product quality. Therefore, technological innovation must be carried out to seek new production technologies and product forms.
As mentioned earlier, the two important indicators of cable trays are: the bearing capacity of the cable tray should meet the requirement that the working uniform load is less than the rated uniform load, and the cable tray should be able to adapt to different environmental requirements and have a longer service life. Therefore, we should consider how to reduce costs from these two aspects.
Firstly, consider the bearing capacity of the cable tray. To reduce the cost of cable trays, the first step is to reduce the thickness of the plates used. The key to solving this problem is to choose low thickness plates for cable trays to meet the original load-bearing capacity requirements, or to choose original thickness plates to meet higher load-bearing capacity requirements. Below, specific analysis will be conducted for different cable trays:
(1) Steel cable tray. Because the structural strength of the profile is higher than that of ordinary flat plates, machine drawing or pressing processes can be used to change the shape of the flat plate of the cable tray to improve its strength. For example, the bottom plate, edge, and cover plate in the main structure of the cable tray are all corrugated structures, or a block like concave convex structure similar to a track is pressed to increase the strength of the cable tray. At the same time, the heat dissipation area increases, and its structure facilitates ventilation and heat exchange, while also reducing the energy loss of cables laid inside the cable tray. This structure can meet the original load-bearing capacity requirements by selecting low thickness plates, which will greatly reduce the use of raw materials. At present, both of these processes have been tried by cable tray manufacturers, and both have achieved good results in use. If further research is conducted in this direction, there should be even more new types of cable trays in the future.
In addition, for places with fewer cables and lighter cables, steel mesh manufacturing can be used instead of steel plates. This structure is flexible in assembly, suitable for various installation situations, convenient for air circulation, and can effectively reduce the impact of electromagnetic interference. This steel mesh cable tray greatly reduces the use of raw materials and effectively controls the cost of raw materials.
