In the production of fasteners, it is the molding of raw materials.The main forming process is cold pier or cold extrusion.Cold pier process belongs to metal pressure processing.It applies external forces to the metal at room temperature and is molded in a mold.The complexity of the fastener has different requirements on the precision and complexity of the die.The forming of fasteners is not only a deformation method of cold heading.In the cold heading process, in addition to upsetting deformation, there are various deformation modes, such as positive and negative extrusion, compound extrusion, stamping and rolling..Cold heading (extrusion) has many advantages and is suitable for the production of a large number of fasteners and special parts.
We also know that non-standard fasteners are related to standard parts.Non-standard fasteners are fasteners that do not need to correspond to the standard, that is, fasteners that do not have strict standard specifications, and are free to be controlled and matched.Typically, the customer requests specific requirements and the fastener manufacturer creates the data based on the data and information.In general, the manufacturing cost of non-standard fasteners is higher than that of standard fasteners.There are many types of non-standard fasteners, and it is difficult to classify non-standard fasteners because of their characteristics.
The big difference between standard fasteners and non-standard fasteners is whether there is standardization.The structure, size, drawing, marking and other aspects of standard fasteners have strict specifications stipulated by the state. The commonly used parts are produced by professional factories.Parts, general standard fasteners have threaded parts, keys, pins, rolling bearings, etc.
Non-standard fasteners are different for each mold.The parts on the mold in contact with the product glue position are usually non-standard parts.The main modules are front modules, back modules and plugins.In addition to screws, faucets, thimbles, leather rings, springs and other moulds almost all are non-standard fasteners.If non-standard fasteners are to be purchased, the manufacturer should normally provide design inputs such as technical specifications and sketches.The supplier will evaluate the difficulty of implementing non-standard fasteners and evaluate the production of non-standard fasteners.Cost, batch, production cycle, etc.Precision hardware processing as opposed to fasteners requires us to recognize the difference
