With the vigorous development of China's automobile industry, the competition is becoming more and more fierce, and the price war is inevitable. The era of high profits for the auto industry will be gone forever. It is an inevitable choice for automobile industry to reduce environmental cost and improve efficiency. Cost reduction involves many factors, such as investment planning, product design, supporting procurement, production process, product sales, process management and so on. From the point of view of the automobile coating technology design, this paper talks about how to reduce the cost.

Powder coating equipment is one of the four processes of automobile manufacture. The large-scale automobile coating line is not only complex in technology, long in construction period, but also huge in engineering investment. Coating environmental protection equipment process design is the painting line construction of the "leading", which not only affects the cost of investment, but also related to the coating quality and production cost, therefore, consider the cost from the source of coating process design. Cost reduction work is very important.

Determination of the production program

Production program is an important design basis for process design, directly related to the cost of investment. The new painting line production program, mainly according to the enterprise development planning and forecasting of the market, because there are many uncertain factors, so the production program is difficult to grasp accurately, too small may not finish production tasks, resulting in loss of market, too much may result in increased costs, not only a waste of construction cost, but also increase the production cost of a single product. The cost of automobile products is closely related to output. In the automobile coating, especially obvious, not reached a certain batch, start large-scale coating line, is likely to lead to loss of production. Some companies have appeared large-scale painting line has been completed, but because no production batch can not start the production line of lessons, resulting in a large number of idle assets, waste of money. In determining the production program, we must be very careful, avoid careless investment, causing significant losses. It is considered that if the expected yield is not clear. Or the product market is expected to require a longer growth process, in the design of production programs may be relatively conservative, or take a rolling development strategy.

The design of the production program is too small, resulting in excessive production capacity problems. Some measures can be taken to improve the annual base and equipment start-up rate of the equipment. Most of the domestic production line and equipment base year starting rate calculation of a considerable margin, when calculated excluding all weekends and holidays, equipment operation rate calculation is lower than abroad, therefore, to improve the equipment and equipment on large space base rate. Increasing the annual base of the equipment and increasing the load rate of the equipment can not only increase production, but also reduce the production cost of a single product.

There are two basic modes of rolling development of coating ability; one is when the production capacity of a production line to meet the needs of production, re construction of a production line; the other is based on the original production line on the supplement, transformation, improve its production capacity. Despite rolling development. But a design plan is important, especially for the second models. In the first stage design, we should design the two stage complement and transformation plan. It is beneficial to reduce the cost and the construction period. Capacity building to the rolling development model. If only considering the unit production capacity investment, may be greater than the one-time investment, but if we consider the investment risk, cost and other factors, the rolling development is a kind of practical ability construction mode. In the domestic automobile industry, there are many such successful precedents.
