In modern technology of production methods, many steps are taken in innovating the highest quality of fastener products. In every principle of differentiating the specified functionality of fasteners, the manufacturing process is classified into cold forming, hot forming, and machining. These steps are taken to adapt and meet the demands of industrial applications. 

Differentiating the kinds of production processes:

Machining 

Machining is the mechanical engineering of manufacturing and assembling materials together, often a form of metal that collectively undergo a process. Since the invention of technology in the evolving world, machining processes have improved from traditional to advanced. Traditional machining includes principal processes (turning, drilling, milling) and miscellaneous categories (boring, broaching, sawing, shaping, planning, reaming, and tapping) which use machine tools that shape the fastener materials.

Conventional machine tools: lathes, milling machines, drill presses, sharp cutting tools, etc.

Advanced machining techniques: CNC machining, electrical discharge machining (EDM), electro-chemical machining (ECM), laser cutting, water jet cutting

Turning – is the operation of rotating materials in a lathe machine to shape and cut the materials into the desired dimension. Latches are the principal cutting tool that is used in workpieces during the turning process.

Milling – are operation wherein milling machines rotate at a high-speed rate for multiple cutting edges. This process allows the formation of special curves and straight lines in a workpiece. Milling machines have rotary cutters that cut materials in speed into a desired final shape.

Drilling – operations that are done through drill presses, lathes, or mills. This method is performed to remove materials from the inside of a workpiece with a rotating cutter to produce a hole. Drilling machines perform processes such as drilling, reaming, lapping, boring, counter-boring, counter-sinking, Spot facing, and tapping.

Machining is commonly done in manufacturing fasteners that have intricate specifications. This method is preferable for applications of bolts and nuts that have critical requirements. Most fastener manufacturers use machining techniques in the acquisition of machinery facilities for their control in production and to support the needs of industries dependent on them. 

Cold Forming 

Cold forming, also known as cold working in metallurgy, is a process of shaping metals below recrystallization temperature to realize the elements of materials. The forming of metal materials in cold temperatures allows them to have enhanced features like tensile strength and corrosion resistance. Cold-forming is a preferable choice of process for manufacturing large quantities of bolts, nuts, and other fasteners. It also offers a cost-effective manner in high-speed process and comparable results to hot forming. Fasteners fabricated in cold forming produce a greater yield, high tensile strength, hard features, and a superior finish.

Four major cold forming techniques and their types:

Squeezing 

• cold rolling
• cold forging
• Extrusion
• Coining
• Swagging
• Sizing
• Riveting
• Staking
• Burnishing
• Thread rolling
• Peening

Bending 

• Angle bending
• Roll bending
• Draw and compression
• Roll forming
• Seaming
• Flanging
• Straightening
•  

Drawing

• Wire drawing
• Tube drawing
• Metal spinning
• Embossing
• Stretch forming
• Sheet metal drawing
• Ironing
• Superplastic forming

Sharing

• Sheet metal shear-cutting
• Slitting
• Blanking
• Piercing
• Lancing
• Perforating
• Notching
• Nibbling
• Shaving
• Trimming
• Cutoff
• Dinking

The advantage of the cold forming process is having an increased strength of the fasteners in controlled dimension, better surface finish, corrosion resistance, reproducibility, and more. Cold-forming is also a low-cost option in production because of the less time required yet mass-producing capacity in manufacturing.

Hot Forming 

Hot Forming is also known as hot working and is another processing of metals that are plastically deformed above recrystallization temperature. It includes the methods of hot rolling, hot spinning, extrusion, forging, drawing, and rotary piercing. An important aspect to maintain during a hot forming process is to control the temperature of the workpiece to have a desirable deformation of materials. 

The advantages of hot forming are having a decrease in yield strength making it an easier piece for installation of the fastener products, increased ductility, lighter components, high formidability of materials, good dimensional stability, and suitability in all steel components.

While the main disadvantages of the process are scaling or rapid oxidation of the workpiece, less precise tolerances, burr formation, the possibility of components warping, and variation in the grain structure of the metal.

Hot rolling – is a contrast to cold rolling wherein metal components are passed through rolling mills to reduce the thickness and make a uniform property. 

Hot spinning – also known as metal spinning, is the process of metalworking in which metals are spun at a high speed by hand or by a CNC lathe. The method doesn’t involve removing an element of the metal but forming or molding the material into an existing shape.

Extrusion – is a metal working process of keeping the metal from strain hardening for an easier way to push it into the die. Its main advantage in the manufacturing process is the ability to work with brittle elements and create an excellent finish. The extrusion process also allows the material to be formidable in freedom to design the desired dimension.

Forging – from the word itself forging is the process of shaping materials into the desired final product such as fasteners. Forging can be classified by the type of temperature in the process, it can be hot forging or cold forging. 

Drawing – is the process of thinning out a metal wire into the necessary thickness. The metal working method uses tensile forces to draw out and stretch components such as metal, glass, or plastic.

Rotary piercing – is another hot metal working process consisting of two types; the Mannesmann process and the Stiefel process. Rotary piercing performs the formation of thick-walled seamless tubing.

The classifications of the production of fasteners are complex in variations hence it aims to convert the materials into their best quality and purpose. With the practice of innovating excellent fastener solutions, many of the fastener suppliers cater to the standard customization needs of every industrial sector. 

How to Choose the Best Quality Fasteners?
