  • Screws Through the Ages

    If you are a fellow glasses wearer, you probably know the sorrows of losing one of the miniature screws that keep your glasses together. I swear once they hit the ground, those screws are forever lost. I always curse whoever thought to employ minute screws to hold together something meant to help me to see. Screws are apart of the fasteners family. The actual concept of screws can be dated back to 200 B.C. Early screws were a part of the Babylonian Hanging Gardens. Assyrian King Sennacherib used screws as...

  • Improving on Cold Heading with Secondary Machining

    Cold heading is the process of shaping semi-cold metal into a variety of different shapes, often used to make customized screws, bolts, and other metal fasteners. The cold heading process uses a large amount of force to transform the metal blank into the desired shape. Many factories use cold heading to manufacture parts and pieces of all different sizes. However, there are fewer factories that continue modifying and improving on cold headed parts with secondary machining methods. Secondary machining methods, like heat treating, rolling, or drilling can help maximize the...

Industry Information

Cold Headed Parts

Cold headed parts are finished or stock shapes produced through a specialized process more broadly known as cold working. Although cold heading is a popular option, it is part of this larger group of manufacturing processes also referred to as cold forming. As the name would suggest, none of these techniques involve heat, but instead materials are processed and formed at ambient temperatures. While the name might imply that the temperature is further reduced for cold metallurgical processes, most are carried out with machines and materials left at room temperature.

Cold working operations include cold extrusion, cold drawing, cold roll forming, impact extrusion and orbital forming. The products of these manufacturing techniques are most commonly smaller items such as cold headed fasteners or more specifically nuts, steel pins, bolts, screws and stainless steel pins which are among the most commonly sought after implements. Many of these are made through the processing of stock forms such as cold heading wire, plate and sheet. Larger items are available, though current technology makes cold heading such products less practical than smaller and less complex objects. While cold formed steel is popular due to its strength and economic stability, other materials such as copper, aluminum, titanium, iron and brass are also processed in this manner. Although specific actions and machines vary based upon the size, material and desired outcome, most cold forming processes utilize extreme pressure to cause the plastic deformation of these metals in order to create the desired internal and external component characteristics.

Cold working processes and equipment are as variable as the many different operations they provide. Cold roll forming machines and cold headers are among the most common pieces of equipment found in a cold working shop. A roll forming machine consists of a series of rolls, commonly made of steel or roller dies. This particular type of equipment is used to produce smooth surfaced strips and sheets of precise thickness and specified cross dimensional shapes. Headers, however, offer more complex forming. While a single die, two blow header is sufficient for some cold heading applications, the production of more complex products requires shops to have a multi-die, multi blow header. This allows for a number of options as upsets, or forming can be eccentric, offset, square or elliptic. Multiple dies are used to reduce size by working the metal down smaller and smaller and also allow for the production of collars, necks, lugs, flats or fins on any point along the length of the stock shape or blank. Another popular process is what is known as cold drawing. In this process a rod is filed or hammered to a point before being placed into the die. A grip is secured to this point and then pulls the metal through the die in effect stretching it. Extrusion works in a similar manner though the materials are pushed through the die or dies rather than pulled. As is evident, dies are a common tool used in virtually every type of cold machining. These serve to confine and direct the material in order to create the desired shape and dimensions. A punch is most often used to transfer the required force from the machine to the part being created. This force must exceed the metal’s elastic limit in order for the blank to undergo plastic deformation thereby permanently taking on the shape of the punch and die mechanism.

Cold working processes offer many benefits to both consumers and manufacturers. As some hot forming operations require heating large and small metallic components to astounding temperatures, cold processes offer significant energy savings. Additional economic value can be attributed to the minimization of waste materials afforded by cold working. Because the materials are altered using predominantly punch and die manufacturing, the metals are deformed and thus remain intact. Other processes such as welding, cutting and drilling on the other hand produce scraps and unused fragments of materials. While these can be recycled, this can be time consuming. Along these same lines, cold formed parts exhibit a particularly solid construction that often requires no secondary operations. Tensile strength and hardness also tend to increase as work hardening results from the repeated pressures on the part. Additionally, reproducible and consistent products can be produced even at high output rates through the use of the cold working process. One of the major differences between hot and cold forming is the tight tolerances for dimensions. Exact measurements are difficult to calibrate and reproduce with high heat applications as metal expands when warmed, but contracts when cooled. Because cold processes impact the materials at room temperature there is no expansion coefficient, meaning precision is more easily predicted and achieved.

The many benefits can be attributed to the ability of cold working to effectively create a more compact and efficient grain structure at the atomic level of the metal providing vast improvements in strength and hardness. Unfortunately this can also increase the internal strain or stress on an object. To combat this effect of cold working processes, annealing is commonly used, especially in applications requiring a number of similar or dissimilar cold working steps. Annealing allows manufacturers to soften the materials slightly in order to relieve some of the tension and improve ductility. Manufacturers often alternate cold working and annealing steps in order to create stock forms and fasteners that have the necessary permanent distortion of the crystal structure and the composition of the metal required for variable applications. Improvements to cold forming services allow for higher speed production as well as the creation of more and more complex components such as spark plugs and axles. Metallurgical and cold working advancements also increase the number of metallic elements and alloys that can be processed in this way. The versatility and simplicity of the cold forming process allows for its use and necessity in a number of industrial settings including construction, automotive, hardware, stamping, injection molding, aerospace, agriculture, recreation, furniture, electronics, pyrotechnics, packaging and upholstery. To accommodate the diverse needs of these industries, many shops offer cold working operations such as sizing, piercing, trimming, thread rolling and pointing in addition to the aforementioned processes. Cold heading service providers may also offer secondary operations such as bending, knurling, drilling, swaging, patching, tapping, shaving and milling as needed.

Types of Cold Headed Parts

  • Cold extrusion is a popular cold working process in which materials are forced through dies or around punches to produce variable lengths of cross-sectional and profile shapes.
  • Cold formed steel refers to any steel components fabricated by the cold forming process.
  • Cold forming is a process through which small, simple parts are produced by applying high pressure instead of heat.
  • Cold headed bolts are some of the most common parts that are made using cold headed metal forming processes. These, along with screws and pins, make up the bulk of cold headed fasteners.
  • Cold headed fasteners are connective mechanisms, like screws, manufactured by the cold heading process.
  • Cold headed pins are made by manufacturers of cold headed parts. These pins have a head that is formed and shaped using the punch and die process.
