Introduction to the characteristics of cold heading process
The cold heading process is applicable to the cold forging and cold extrusion forming (positive extrusion, reverse extrusion, and composite extrusion) of materials such as iron, copper, stainless steel, alloy steel, titanium alloy, and aluminum. It can manufacture various sizes of internal and external hexagonal screws, flange screws, hollow, and solid special-shaped parts. The products […]
What are the requirements of raw materials for a cold heading machine?
The chemical composition and mechanical properties of the raw materials for cold heading should comply with relevant standards for multi-station automatic cold heading machines. The raw materials must undergo spheroidizing annealing treatment, with a metallographic structure of spheroidized pearlite at levels 4-6. In terms of hardness, to minimize the tendency of material cracking and enhance […]
Introduce cold heading machine，screw machine and nut machine

The history and workings of cold heading machines
The history and workings of cold heading machines can be traced back to its earliest inception in Germany. The primary motivation for developing the cold heading machine was to manufacture a large number of bullet casings during World War II. (1) Under the principle of metal plastic deformation theory, a specific pressure is applied to […]
Five key points to consider when operating a cold heading machine
Here are five key points to consider when operating a cold heading machine: The end of the rebar to be used in the cold heading machine should be ground flat to ensure an accurate shape of the cold heading anchor head. After the rebar is headed with a multi-station cold heading machine, it should undergo […]
Basic knowledge about cold heading
Cold Forging: Leveraging the plasticity of metals and applying cold state mechanics to exert pressure or cold draw, the objective is to attain solid-state deformation of metal. This involves creating a method of forging at room temperature to thicken the top of bars or wires, often referred to as cold extrusion. The primary use of […]
History of cold heading machine
Cold heading machine is a specialized equipment used for mass production of fasteners such as nuts and bolts. It is a type of stamping processing machine in mechanical manufacturing. Cold heading is the process of forming metal at room temperature. The use of the cold heading technique to produce fasteners is not only efficient and […]
What cold forging is and how it works
Cold forging is a metal shaping & manufacturing process where a metal bar or billet is shaped by applying pressure at room temperature or below its recrystallization temperature. During cold forging, the plastic deformation of metal causes an alteration in its shape. The benefits of cold forging include efficiency, as it requires less time compared […]
History and intricacies of cold heading machines
Cold heading machines, also known as forming machines, came into the industrial landscape during the late 19th and early 20th centuries. This was a period marked by rapid industrialization and manufacturing innovation. They were designed as a response to the rising need for efficient and seamless manufacturing, particularly in the field of fastener creation. By […]
