Spraying is an important part of the four major processing technologies in the automobile industry. Generally, the car spraying production line is not only complicated in processing technology, long in construction period, but also has great investment in the project. As a basic "root" of the construction of the spraying production line, painting process design, not only largely affect the project investment cost, and it also determines the spraying quality and product cost, therefore, from the consideration on the painting production line process design source to excavate potential, saves the project investment and operation cost, It is very critical to the sustainable development view and cost management of enterprises. We will be from the technical level clear, machine equipment selection, selection of raw materials, power and energy countermeasures and other 6 levels to do in-depth discussion.
The manufacturing outline is an important link of the process technology, which is immediately related to the investment cost of the project. The production and manufacturing outline of the spraying production line under construction is clear, mainly according to the company's construction plan and forecast analysis of the sales market, because there are many uncertain factors, so the production and manufacturing outline can not be grasped accurately. Very small will not be able to complete the daily tasks of production, resulting in sales and market damage, very large will lead to cost increase, not only the extravagant waste of capital construction project investment costs, and will continue to increase the product cost of spare goods. For the production line where the production capacity exceeds the design specification and the manufacturing outline of the design scheme is too small, we can update and transform the bottleneck process, increase the annual number of machinery and equipment, increase the load of machinery and equipment to improve benefits and reduce the cost of bicycle products.
The technical level of coating production line immediately decides the project investment cost and the product cost after. Clarifying the technical level is a complex task. To solve the product positioning, coating quality requirements, the company's management level, the company's economic development and other comprehensive analysis, from low to high selection of appropriate levels. The clear technical level should be as far as possible to ensure just right, without too much pursuit of perfect "all-round excellence". Many painting process design program staff in clear technical level, habitual choice of high rather than low commercial insurance practice, usually resulting in excess of cost rise. In fact, the main standard of clear technical level is that the processing technology is suitable for the quality of commodity coating, and then the integration of the company's management level, economic development, economic benefits and other comprehensive consideration.
The plan of the processing process is a key component of the process technology, is a comprehensive reflection of all the data and information measurement, in addition, it is a complicated work, the plan of the plan should be improved, and then improved, select the best practical effect. If the layout is not scientific, it will lead to long-term production trouble, product quality problems can not be solved, resulting in ineffective labor, increase the cost of products.
4. Machine and equipment model selection
The model choice of the main equipment of the car spraying production line reflects the height of the technical level, and will immediately harm the investment cost, product quality and product cost of the project. For example: the model selection of automatic spraying equipment in the car body spraying production line, the selection of very simple gas spray gun manual service spray painting, the project investment cost is the least, but the high efficiency of spray painting is very low, the utilization rate of paint is generally 30% ~ 40%;
And the choice of the most outstanding contemporary high speed electrostatic induction cup automatic spraying machine or intelligent robot, spray painting efficiency can do 85%, can save a lot of paint raw materials and waste paint to solve the cost, and spraying quality is significantly better than other spray painting methods, but automatic spraying system software price is very expensive. Choose which automatic spraying equipment comprehensive cost more low, the key according to manufacture large quantities of elements such as clear, to a large number of high-grade production line, selection of spray paint more cost-effective high efficient automatic spraying machine, total output at less than 30000 sets of production lines, from the perspective of project investment and operation to choose artificial service method is more cost-effective economic development. Intelligent robots can paint the inside and outside surface of the car body. With the development trend of automation technology, the price drops, and the spraying robot may be gradually expanded.
