In fact, for a factory, the most important thing is whether it can produce suitable quality guaranteed products according to the requirements of customers. For a good quality good product, a complete precision production process. Chéng) is very important. The main purpose of the custom screws is to make the industrial products fixed and integrated. In use, it often happens that there is no close between the teeth and the teeth, if the screw head is broken too tightly, or the teeth are not tightly locked, the conditions are not met. The accuracy of the quality problem. The first step in the process is often destined to the basic features of this product, this step is good and bad for this product is essential. This is like the first step in our learning to walk. It will often form our own walking style, so this step must be taken well. Especially for screw factory production, the precision of the screw is very high, and the deviation value has a certain degree of inspection. Otherwise, the quality of the industry is not guaranteed. Annealing is often the first step in their production process. Now we need to have a certain understanding of the retreat (Find out), so that we know what the attention is (Emerson) , there will be no quality problems.
Annealing, as the name implies, heats the material to a certain temperature, maintains it at a certain temperature, and then slowly cools it. The reason for this is that the hardness of the sheet can be reduced. The late processing has a certain significance. Electrical screw precision is usually 6g (2nd grade, U.S. specification "IFI" is 2A teeth), crude screw used in construction projects is 8g (3rd grade, "IFI" is 1A teeth). The value of screws is very important. There are examples in the world of bankruptcies caused by poor screw quality. There are also examples of aircraft falling down and vehicles being subverted due to poor screws. Stainless steel screw refers to the shape of a screw made of stainless steel screw wire rod, and it is threaded in the rear. Its material is stainless steel. Stainless steel screws are divided into stainless steel SUS201 screws, stainless steel SUS304 screws, and stainless steel SUS316 screws. First place the plate in the fire, keep a good habit of covering, and then let the temperature in the furnace rise slowly in a certain period of time. It is worth noting that we should not increase the temperature too fast, nor too much. Slow, such speed will affect the effect of backwards. The job is to ensure that the furnace has a certain temperature, and different materials have different temperature requirements. Our experience is very demanding and we must implement this step strictly according to the specified temperature. The next step is to slowly cool down. The same is true here. Don't overdo it or not. It is also crucial to ensure a good cooling rate. After the end of the annealing, we must carefully inspect the structure of this process to see if it meets the standards and whether the hardness is correct or not. This problem (Emerson) is all we should pay attention to. When we perform the first step of screw manufacturing, we must have such an attitude to do it.
