With the continuous development of industry in recent years, the common screws already can't meet demands of some products. For this reason, the non-standard customized screws comes along. Some people might be curious about what’s the difference of workmanship between the non-standard screws and the standard screws? Now I'm going to share with you what are the steps of non-standard customization screws.
1.Before the customization of non-standard screws, you should think it clear what effect do you want the non-standard screws to reach on the products, for example, anti-theft, anti-loosen, or to achieve the demand of products' feature?
2.Design the presentation, standard, size, type of head and driver according to the demand of products. Decide the material and surface treatment of the non-standard screws taking the product itself and using environment into consideration.Generally the drawing of non-standard screws are designed by the demand side. They need to sign on the drawing the standard, the size and the others demands of different parts of screws. If there are no drawings, the manufacture can also design the non-standard screws according to the actual situation as long as be provided the product for which the non-standard screws apply or the requirements of the non-standard bolts.
3.After the design of drawing, we should make sample and produce it. We also need to decide if it’s necessary to make a new mold according to the demands of screws in case of ordering one from a mold factory.
4.We test the samples to insure they are qualified after the production, then we send them to clients to install them on the products to test if they are suitable. After the confirmation of samples we turn the process into mass production.
