  Cold Heading Dies Used in the cold heading process, where metal is formed at room temperature. These dies shape wire or rod stock into fasteners like bolts, screws, and rivets by applying high pressure. Typically made from high-hardness materials like tungsten carbide or tool steels to withstand repeated high-stress impacts. Punch Dies Part of a punching or stamping system, used to create holes or shapes in sheet metal. The punch (male part) presses into the die (female part) to cut or form the material. Often made from tool steel or carbide for durability and precision. Trimming Dies Used to remove excess material (flashing) from a workpiece after forming operations like stamping, forging, or casting. Helps achieve the final part shape and smooth edges. Typically made from hardened tool steels or carbide for long life and precision trimming. Flat Thread Rolling Dies Used in the thread rolling process to form external threads on fasteners or other components. Unlike cutting threads, thread rolling displaces the metal to form the thread, resulting in stronger threads. Flat dies are used in flat die thread rolling machines. Made from hardened tool steel or tungsten carbide for wear resistance. Tungsten Carbide Dies Dies made from tungsten carbide, a very hard and wear-resistant material. Used in high-volume, high-precision applications where tool life and surface finish are critical. Commonly used in cold heading, thread rolling, and fine blanking operations

Cold Forming moves material rather than removes material hence little or no scrap Cold Forming manipulates & maintains grain flow and increases structural strength through work hardening Cold Forming is a rapid process suitable for large quantities Recent technology advances have enhanced the precision, capability and performance of cold forming equipment Rapid changeover technology (SMED) enables modern lean manufacturing techniques to be employed

A dramatically increased number of overseas buyers visited the first phase of the 137th China Import and Export Fair, the country's largest trade event, amid the uncertain global trade situation, according to the fair organizers. With a theme of displaying China's advanced manufacturing, the fair's first phase concluded on Saturday, with 148,585 overseas buyers from 216 countries and regions in attendance, marking a 20.2 percent increase compared to the same period of the fair's 135 session.

The 137th edition of the China Import and Export Fair, also known as the Canton Fair, is scheduled to take place from April 15 to May 5 in the southern Chinese city of Guangzhou, with some 31,000 participating firms, the China Foreign Trade Center said on Wednesday. The total exhibition area will span 1.55 million square meters with about 74,000 booths, including nearly 73,000 for exports and about 1,600 for imports. This fair will be divided into three phases: the first will focus on advanced manufacturing, the second on quality home furnishings, and the third on products that promote a better quality of life, involving 172 product zones. The number of participating firms is up by nearly 900 compared with the previous fair. For the first time, a special zone for service robots will be added in the first phase to focus on the latest achievements of China's AI development. Established in 1957, the Canton Fair is held twice a year in Guangzhou. It is the longest-running of several comprehensive international trade events in China, and has been hailed as the barometer of China's foreign trade.

Provided are rotary dies that can cut amorphous materials while having suppressed wear. The rotary dies are adapted to cut a target, and include an anvil roller, a die cutter, a first elastic portion, and a second elastic portion. The anvil roller rotates while supporting the target. The die cutter has a projecting edge for cutting the target and is configured to rotate. The first elastic portion is arranged on the outer peripheral surface of the anvil roller, and elastically deforms upon contacting the rear surface of the target when the target is cut. The second elastic portion is arranged on the outer peripheral surface of the die cutter, and elastically deforms upon contacting the front surface of the target when the target is cut. The hardness of the first elastic portion is greater than that of the second elastic portion.

To produce multiple and diversified kinds of part inexpensively and easily by providing mechanisms that can adjust the position of a die from the outside of a slider in a rotary forging machine. CONSTITUTION:Prior to performing of production of parts, a handle 42 projecting to the outer part of a slider 19 is rotated to rotate a geared nut 34 by way of a worm 40, a worm gear 39 and the 1st gear 38. The nut 34 rotates on the outside circumference on the 1st ram 32, and a slider 19 moves upward and downward with respect to the 1st ram 32. By the upward and downward movements of this slider 19, the position of a die 27 of the time when the 1st ram 32 reaches the top end of the 1st cylinder barrel 31 is selected in accordance with the shape of desired parts. Thence, the blank material held in the die 27 with respect to a punch 11 making precession is brought to the prescribed position corresponding to the shape of the parts by the operation of the 1st cylinder system of a two-step stroke cylinder 30, and in that position, it is locally pressed by the punch 11, whereby it is gradually deformed and the parts of a desired shape are produced.

The Cologne Hardware Show in Germany is a biennial large-scale international hardware exhibition, which was launched for the first time after the epidemic of four years, with about 1,400 exhibitors from 50 countries and about 25,000 visitors from 140 countries and regions. The products on display range from hardware tools and accessories to construction and DIY supplies, all the way to fasteners, fixtures and accessories. Among them, there are 298 Chinese exhibitors with a scheduled area of 3888 square meters, which confirms its importance as the largest trade fair in the international hardware industry.

What is cold heading: Simply put: cold heading is feeding wire into a machine, cutting it into pieces, and hammering on it. The material is not heated or machined, but formed into its desired shape at room temperature. The ability to form material instead of removing it deems this process extremely efficient and cost effective when manufacturing large quantities. :,,.,., we design and fabricate our own custom tooling and manufacture nearly all fastener forms including multiple upset configurations, customized head shapes, and substitutions for multi-part assemblies. Converting your supply needs to cold heading can benefit in many ways ,,,.. · Tight Tolerances · High Speed Production Rates · Large Volume Capabilities · Reduced Raw Material Waste · Improved Physical Properties · Reduction in Cost Vs Machining · Capabilities Include a Large Range of Diameters · Standard and non-standard configurations are made to the customer`s specifications · Many secondary operations available to complete fully customized parts Vs

Cold Heading Terms: Cut-off: A specific length of wire that is cut off from a coil of wire prior to going into the heading die. Heading Die: A stationary piece of tooling that has the specific geometry for the part machined into its cavity used to form parts. Punch: A piece of tooling that moves, striking the cut-off slug to upset material and push it into the heading die. Knockout Pin: (used for two purposes) 1. To serve as a support against which the blank rests while it is being headed. 2. To eject the part out of each die. Diameter of Upset: The amount of material that can be upset to form a head of a fastener. A length of wire equal to its diameter. The term [1 diameter of upset" only moves a small amount of material to form the head of a fastener. The term [4 ½ diameters of upset" involves moving a lot of material to form the head of a fastener. The larger the diameter of upset – the larger the head diameter can be made. Upsetting: Striking an object on its end causing the existing diameter to increase in size. Extrusion: Forcing into a die causing the diameter to become smaller Grain Flow: The grain flow of the existing material is either interrupted (as in machining) or uninterrupted (as in cold heading). A part that has an interrupted grain flow is weaker than a part with uninterrupted grain flow. Cold-formed parts are stronger because the internal grain structure follows the contour of the part.
