What Are The Differences Between Non-standard Fasteners And Fasteners?
Oct 30, 2017

Non-standard fasteners refer to fasteners that do not need to correspond to the standard. That is, there is no strict standard specifications of fasteners, can be free to control collocation, usually by the customer to put forward specific requirements, and then by the fastener manufacturer based on these data and information to manufacture, the general non-standard fasteners manufacturing costs higher than the standard fasteners. There are many kinds of non-standard fasteners, because of this characteristic of non-standard fasteners, it is difficult for non-standard fasteners to have a standard classification.

The biggest difference between a standard fastener and a non-standard fastener is that there is no standardization, standard fasteners of the structure, size, painting, marking and other aspects of the strict norms of the country, by the professional factory production of commonly used 0 (part) pieces, common standard fasteners have threaded parts, keys, pins, rolling bearings and so on.

Non-standard fasteners are not the same as each mold, the mold and the product of the plastic contact parts are generally non-standard parts, the main has a front die, after the mold, insert. It can also be said that in addition to screws, water nozzle, thimble, aprons, springs, mold embryo the rest of the almost all non-standard fasteners. If you want to purchase non-standard fasteners, generally should be provided by the need to provide technical specifications, drawings, such as grass-like design input, from the supplier to evaluate the implementation of non-standard fasteners, and preliminary estimates of non-standard fasteners production costs, batch, production cycle and so on.

In the production of fasteners, the first step is the raw material forming, the main process is cold pier or become cold extrusion. Cold pier process belongs to the metal pressure processing, is under the normal temperature condition to the metal to exert the external force, in the mold internal molding, the fastener complex degree to the mold precision and the complexity has the different request. The forming of fasteners is not only a deformation mode of cold upsetting, but also a variety of deformation modes, such as positive, reverse extrusion, compound extrusion, punching and rolling, in addition to upsetting deformation during cold heading. Heading (squeeze) a lot of advantages, suitable for large quantities of fasteners, special pieces of production scenarios.

We also know that non-standard fasteners are relative to standard parts, non-standard fasteners refer to the fasteners that do not need to correspond to the standard, that is, there is no strict standard specifications of fasteners, can be free to control collocation, usually by the customer to put forward specific requirements, and then by the manufacturer of fasteners based on these data and information to make, The manufacturing cost of the general non-standard fasteners is higher than the standard fasteners. There are many kinds of non-standard fasteners, because of this characteristic of non-standard fasteners, it is difficult for non-standard fasteners to have a standard classification.
