Today received the customer needs to customize the car vacuum cleaner filter requirements, Xiaowang students began to be a bit confused state. Car vacuum cleaner filter mesh is relatively small, for often etching thickness 2MM products Xiaowang students this is really a not small experience, so Xiaowang found an engineer to determine at 0.05 thickness can etch this mesh.

Xiao Wang's first task is to find the project leader, the project team leader, to explain the actual length, width, thickness, etc. of this mesh, together with a package to the drafting engineering department, the development of engineering plans for this mesh, the next few days is the full process of the implementation of the car vacuum cleaner filter.

The first arrangement of the project team leader is the engineering cartography to perfect the corresponding details and arrange the production of metal film, which is an indispensable link in the later production process. Next is to extract the stainless steel material from the warehouse, and the material through the automated machine cut into the corresponding size of the stainless steel plate, such as 300MM long, 200MM wide stainless steel plate, which is not the actual size of the customer's products, the reason is that in the etching process, need to exceed a certain percentage, or the product will be scrapped or too small.

This is the first step of the etching process, namely material preparation. Xiao Wang looked at the material excitedly and imagined the moment when it became a product. Next, the pre-engineer will pull the material to the fourth floor of the Zhuolida etching processing plant of the raw material processing process department, stainless steel early existence of surface dirt and grease, cutting is completed by the need to deal with the raw material, the dirt and grease to remove. If the situation is not flat then need to add another process, that is, through the flattening machine for stainless steel flattening treatment. After the completion of raw material processing, Wang saw the machine again transmitted to the laminating stage, which is a high temperature and the smell is particularly unpleasant, so did not go in, but out is the stainless steel covered with a blue film, and this is the etching process of pressing process, that is, the laminating stage, through the laminating completed stainless steel then enter the exposure stage, which is a relatively sealed environment, inside the Staff need to wear protective clothing, because the exposure has a strong ultraviolet light. Xiaowang students through the window to see the staff will be laminated stainless steel into the exposure machine, set on the corresponding machine, a strong sense of light in the press below the walk through, so bright so dazzling. This exposure process is similar to the scanning we do on large printers similar, and the exposure needs to have previously set the metal film pattern transferred to the laminated stainless steel material, the common understanding is how the pattern on the cross-roll is transferred to the photo paper? And that is also done through the acidic potion. Wang looked at all this in amazement, sighing that this is not a technical upgrade is an art of presentation.

After the completion of the exposure process that is through the development process, need to consider the later part of the corrosion off with the corrosion off the function, should not be corroded off the part needs to be well protected, and the development that is the basic outline of the pattern has been completed, while this situation, the stainless steel material will also appear softened, now if taken to etching, the whole will be corroded off. Therefore, it is necessary to dry the process, the original softening of the material itself to form a strong hard stainless steel material, after the completion of the drying process. Xiaowang students to help pull the material to the etching machine, so as to really go to the etching process, there are a lot of spray irrigation head, next to the chemical containers, filled with a lot of chemicals, in the deployment of the appropriate agent in the etching machine set the appropriate parameters, in the transmission to the corresponding products constantly put, the machine will automatically dissolve the material corrosion, the final formation with a blue film The machine will automatically corrode and dissolve the material, and finally form a product style with a blue film, so that you can see the upcoming products. Wang watched the engineer dragged out a, the first quality inspection, on the basis of a magnifying glass to see the effect of etching out, no problem that is put into the loaded container, the container has water, so as not to adsorb each other in the process of stacking products, next, is the last process into the product, that is, the etching stripping stage, the product after the completion of etching, again into the stripping machine for stripping, also Is a new round of chemical agents to remove the blue film on the surface, after the completion of the process through clear water on the spray wash, so that the complete product that is through the conveyor belt, transported to the terminal, the tail engineer will be all the products through a layer of white paper put product indirectly collected, and then into the quality inspection department for testing, and the product through the manual disassembly of the way, the etching into the finished product disassembly out. Xiao Wang asked curiously, "Why this process is not carried out by automatic disassembly of the machine?" The engineer replied, "machine disassembly is a mandatory disassembly method, that is, violent disassembly, which will damage the integrity of the product leading to bending, deformation, etc., and some etching process of plugging holes or carving through can not be found, even with such a process cost is not a small investment, manual disassembly is more conducive to packaging and timely detection of these problems ".

The whole process of car vacuum cleaner filter etching just stunned Xiao Wang, looking at the full load of products into the loaded car for a long time can not calm, constantly looking back at the etching process of each process.
