Nowadays more and more products are needed for customization. A lot of manufacturers will improve the appearance or performance of their products. Accordingly, many parts have also been improved to varying degrees. When Engineering was designed, it was an unusual road. Sometimes a small screw became different. A standard screw is changed to a screw, but it may not be known to the design and procurement staff. So we often have such a conversation at work; Miss Song, I will produce this screw, and the drawing will be sent to you. Please check! Our business team received a drawing and saw it with only one screw, then next to it was M4*10, stainless steel (stainless acid-resistant steel). Then, no then.
So the business team will ask Mr. xx, your size specifications of this screw is not complete, you have to be specific, I can quote production. Precision Screws Small screws, also known as tiny screws, are tiny fasteners that connect the material of the product. They are tiny in shape, but they can play a key role in the production of key parts. Widely used in electronics, electrical, electrical appliances, furniture, machinery and equipment. This is an ordinary hexagonal screw. You can produce it according to the appearance and size of the drawing. How is it? Not many people have read it. The vast majority of people will answer in this way. In fact, it appears to many people that ordinary screws are not ordinary. Even standard screws require standard numbers. Then there will appear, our business and technical group, in order to allow customers to get the Price and production methods of Precision size products, we need to say a few about the size and surface treatment (chǔ lǐ), and come to purchase The procurement staff of the screws had to ask their technical team, so that communication back and forth several times, sometimes two days can not completely complete the data (data). This wastes a lot of time, but also increases the workload of the other party's procurement and technical staff, but it can't be ignored. Then, when a screw is customized, what kind of data must be provided in order to complete the quotation production process quickly and efficiently?
1, the material quality of the screw, this is the most basic to be clear.
2, screw head type, groove type. 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. How big is the diameter of the head, how much is the thickness, the depth of the groove, or are there special requirements?
3, screw diameter, length of teeth, tooth pitch, self-tapping or mechanical, all need to be clear and clear.
4. What is the method of surface treatment of screws (chǔ lǐ)? Is there a requirement for hardness and is there a requirement for grade?
5. What are the main scenarios or products?
6, the number of specific production.
The above points are the most basic data (data) for purchasing a common screw, but must also be a blueprint or a sample comparison. The lack of a single piece of data cannot be accurate quotation or production. Non-standard screws are indispensable industrial necessities in daily life: tiny screws such as cameras, eyeglasses, watches, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; as for engineering, architecture, bridges, etc. Use large screws and nuts; transport equipment, airplanes, trams, cars, etc. If the above data is basically absent, then at least the original part that needs to be assembled with the screw needs to be provided, let the screw R&D production technician design and develop it. Ready to do this, you can effectively conduct procurement communication, greatly improving the efficiency of the work.
