What are the common problems on the coating production line?

Coating equipment, working environment, coating management, coating process and materials are directly related to the production efficiency of the coating line. In this process, the process layout of the coating equipment has an important impact on the use of the coating line. Let's understand the typical errors of the process layout of the coating equipment.

1. The output design guidelines cannot reach:

Some designs do not consider the hanging method of painting equipment (different hanging methods should be considered for different painting pendants), the spacing of the hanging, the interference of the up-and-down slope, the horizontal turning distance, and the production time. Consider the scrap rate, the utilization rate of coating equipment, the peak production capacity of the product, and so on. This will cause the output to fall short of the design guidelines.

Second, there is a deviation in the process time of the coating equipment

In order to reduce the cost, some designers often achieve their goals by reducing the process time. Generally, the common ones are as follows: 1. The pre-treatment transition period of the coating production line is not enough time, which will cause liquid leakage; 2. The specific heating time is not considered during curing, resulting in poor curing; 3. The spray paint leveling time is not enough, thus causing The paint film leveling is not enough; 4. The cooling time after curing is not enough, so that the workpiece is overheated or not fixed enough during painting (or the next part).

3. Improper design of conveying equipment:

From a design point of view, there are many ways to convey the workpiece. If the design is not appropriate, it will easily have adverse consequences for production capacity, process operations, and upper and lower parts. Suspended chain conveying is common, and its load capacity and traction capacity need to be calculated and interfered with drawing. The speed of the chain also has corresponding requirements for the matching of equipment. Painting equipment also has requirements for the stability and synchronization of the chain. When designing, these aspects must be considered properly.

4. Improper selection of coating equipment:

Because different products have different requirements, equipment selection is also different, and various coating equipment have their advantages and disadvantages. If the design cannot be explained to the user, the coating line will be found to be very unsatisfactory to the customer after the manufacturing is completed. For example, air curtains are used to insulate powder spray drying tunnels and cleanliness requirements are not installed with purification equipment. Such errors are common errors in the process layout of coating equipment.

5. Improper selection of process parameters of coating equipment:

Generally speaking, it is more common for this coating production line to select wrong process parameters. One is the improper selection of design parameters for a single coating equipment, the other is insufficient attention to the compatibility of the equipment system, and the third is no design at all.

6. Defects of matching coating equipment:

There are many related equipment in the painting line, and sometimes in order to reduce the price, some equipment is omitted. It also failed to explain to users that misunderstandings and the like are also common. The common ones are pre-treatment heating equipment, spraying equipment, air source equipment, exhaust pipe equipment, environmental protection equipment and so on.

Seven, did not consider the issue of energy-saving coating equipment:

For the time being, this energy price changes relatively quickly, and if these issues are not taken into account in the design, the user's production costs are higher, and some users have to remodel and purchase equipment within a short period of time. This is not the case. What the customer wants. The quality of the design of the coating equipment process layout is crucial to the use of the coating production line. If the process layout of the coating equipment is improper, even if the individual equipment is made well, the entire coating production line will not be easy to use. Therefore, when designing, avoid these common mistakes above and cause losses!
