How Bolts Are Production

Whether you are a forging manufacturer, or a bolt distributor, it is important to know how bolts are produced. This article will help you to understand the different stages of production. The process of making bolts includes Cold forging, Threading, Hardening, and Tempering.

Cold forging

Despite the fact that cold forging can be a very effective method for nickel 200 bolts production, the process has some limitations. The main limitation is that it cannot create intricate designs. However, cold forging is also a cost-effective method, as it saves up to 70% of the raw materials needed for production.

Cold forging is done by using special equipment that are designed to form metal. The equipment must be durable and can withstand repeated force. It also needs to be mass balanced to reduce vibrations.

Cold forging is a method of producing a wide variety of metals including stainless steel, copper, brass, aluminum, and magnesium. Metals with a hardness of 44 HRC are ideal for cold forging, but soft metals can also be forged.

Cold forging is commonly used to produce military hardware. Its advantages include high production rates, low cost, and excellent dimensional accuracy. In addition, cold forging does not require heat treatment. This method saves on secondary processing and allows for a longer lifespan for the parts.

Cold heading

During the manufacturing process of bolts, cold heading is a common method to make custom fasteners. It is a technique that uses a series of dies and punches to produce the bolt head. It is a process that is typically a high-speed operation. It is an efficient process, as it results in a small amount of waste and a large amount of raw material savings.

Cold heading has been around for 150 years. It was developed for the production of fasteners. It is a cost-effective process and is used for a wide range of applications. It can produce a wide variety of standard parts or custom fasteners. It uses high-speed automated part formers.

The first part of the process is to acquire the metal. It is then sheared to the desired length at the right pressure. The wire is then shaped and placed into a die. The wire may be enclosed in a die, or it may be open.

Threading

Choosing the right threading method in production of bolts is very important. It is not only a way to get a better product, but also a way to ensure that the bolts are made to the correct specifications.

The threading process can be divided into two main categories: roll threading and cut threading. The former is a very efficient method and often saves a lot of money. The latter is more labor intensive, but it can produce longer thread lengths and diameters.

For roll threading, a hardened steel die is introduced into the blank bolt and leads the newly formed thread roots outward. The die also adds strength to the bolt.

In cut threading, the material is withdrawn from a round bar of steel. The material is then shaped, leaving tear marks and travels into the fastener body. Unlike rolled threads, there are not any limitations to the diameter of the thread. Nevertheless, the process can be more labor intensive, and it does not produce as smooth a thread.

Hardening & tempering

Depending on the materials used in the construction of a bolt, the process of hardening and tempering can increase or decrease the material's properties. These processes are used to strengthen fasteners and extend their service life. The process can be accomplished in several different ways.

The first process involves heating steel to a desired hardening temperature. The temperature depends on the type of steel and its composition. Once the steel reaches the hardening temperature, it is cooled rapidly. This reduces internal stresses. After the hardening process, the parts are dried and checked for operations.

The second step is tempering. Tempering is a process of heating the material to a low temperature to relieve internal stresses. Tempering also develops final mechanical properties. Tempering can be done in a variety of environments. Some of these environments include a gaseous atmosphere, molten salt, and vacuum.

Tempering can also be performed in water. However, it is important to note that the temperature of the water must be kept above the carbon content of the material. Low temperatures can seriously affect the mechanical properties of the material.
