What Are the Differences between Cold Heading and Cold Extrusion

  Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion is an extrusion deformation of larger workpieces and has a wide range of uses.This shows that, Non standard hardware factory It has a strong development pulse and is an indispensable source of power for the development of the industry. https://jieruifasteners.com/

  

  1. What is cold extrusion

  

  Cold extrusion is a processing method in which a metal blank is placed in a cold extrusion die cavity and, at room temperature, a punch fixed on the press is used to apply pressure to the blank to cause the metal blank to undergo plastic deformation to produce parts. Obviously, cold extrusion processing relies on the die to control the flow of metal and relies on the large-scale transfer of metal volume to form parts. In terms of extrusion equipment, my country has the ability to design and manufacture extrusion presses of various tonnages. In addition to using general mechanical presses, hydraulic presses, and cold extrusion presses, friction presses and high-speed and high-energy equipment have also been successfully used for cold extrusion production.

  

  At present, cold extrusion technology has been widely used in industrial sectors such as fasteners, machinery, instruments, electrical appliances, light industry, aerospace, shipbuilding, and military industry, and has become one of the indispensable and important processing methods in metal plastic volume forming technology. With the advancement of science and technology and the continuous improvement of product technical requirements in the automobile, motorcycle, household appliances and other industries, cold extrusion production technology has gradually become the development direction of refined production of small and medium-sized forgings.

  

  

  2. What is cold heading

  

  Cold heading is one of the new processes of metal pressure processing with little or no cutting. It is a processing method that uses the plastic deformation of metal under the action of external force, and with the help of a mold, the metal volume is redistributed and transferred to form the required parts or blanks. The cold heading process is most suitable for the production of non standard fasteners such as bolts, screws, nuts, rivets, and pins. The commonly used equipment for cold heading is a dedicated cold heading machine. If the production volume is not too large, it can also be replaced by a crank press or a friction press.

  

  Cold heading technology has high productivity, good product quality, and greatly reduces material consumption, reduces production costs, and improves working conditions. Therefore, it is more and more widely used in mechanical manufacturing, especially in the production of standard fasteners. Among them, the most representative products produced by multi-station cold heading machines are bolts, screws and nuts.

  

  3. Are cold heading and cold extrusion the same thing?

  

  Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion, on the other hand, is an extrusion deformation of larger workpieces and is widely used; cold heading is equivalent to a branch of cold extrusion. Simply put, in the process of making bolts, hexagonal head forming is cold heading, and rod diameter reduction is cold extrusion (positive extrusion). Non-cut hexagonal flange bolts (multi-station forming) have both cold heading and cold extrusion. The front shaping of hexagonal nuts is only cold heading, and the hole extrusion in the back process is cold extrusion (positive and negative extrusion).

What Are Biodegradable Pla Gloves_

  In daily life, we often use plastic PE gloves. Plastic gloves are disposable items that are easily consumed in daily life. We use a pair for stewed food, a pair for crayfish, and a pair for home hygiene. While plastic gloves provide us with convenience, they also cause a certain degree of environmental pollution due to excessive use and lack of recycling, becoming “white garbage”. As environmental protection becomes more and more important, we need to enhance our environmental awareness and pay attention to this matter.For these reasons, I think biodegradable mailing bags The situation is still optimistic, and the market is still in a blue ocean stage. https://biodegradable-gd.com

  

  

  Biodegradable PLA gloves are disposable gloves made from polylactic acid (PLA), a biodegradable and bioactive thermoplastic derived from renewable resources like corn starch or sugarcane. Unlike traditional disposable gloves made from synthetic materials such as nitrile or latex, PLA gloves are designed to break down more quickly and sustainably in the environment. Here¨s a detailed look at compostable PLA gloves:

  

  

  Benefits of biodegradable gloves:

  

  1. The performance remains unchanged during the shelf life, and after use, it can be degraded into inorganic substances such as carbon dioxide and water under natural environmental conditions, becoming nutrients for plants and will not pollute the environment

  

  2. Easy to use, not only green and healthy, but also very convenient to use

  

  3. The raw material source of biodegradable gloves is very environmentally friendly. The raw material comes from polylactic acid PLA, which comes from plant resources such as corn and potatoes. It is green, environmentally friendly and sustainable. It will not come from petroleum like plastic PE gloves, which is not sustainable, and the production process is very polluting.

  

  

  When purchasing compostable gloves, we need to try to choose large platforms for purchase. When purchasing, you need to confirm the ingredients of the biodegradable gloves with the merchant, which are generally polylactic acid PLA, polyadipate PBAT, and starch. Others such as PE+starch are pseudo-degradable gloves, not qualified degradable gloves, and need to be purchased with caution.

  

  Biodegradable PLA gloves are a promising alternative to traditional disposable gloves, offering significant environmental benefits through the use of renewable resources and compostable materials. As technology and manufacturing processes advance, the performance and accessibility of compostable PLA gloves are likely to improve, making them a viable option for a broader range of applications.

What Are the Characteristics of Fastener Cold Heading Process

  Cold heading is a common process for manufacturing the heads of fasteners such as bolts, screws, pins, rivets, etc. In many cases, heading is actually a type of cold heading. Cold heading is a forging method that uses a die to compress and shape metal bars at room temperature.Therefore, Non standard hardware factory Only then will more and more pump owners cheer for it and spread the value and function of the brand. https://jieruifasteners.com/

 

  

  The specific operation process is to put the metal bar into the cold heading machine and extrude it into shape through pressure. During the extrusion process, the metal bar will undergo plastic deformation, thereby changing its shape and size, and the head of the fastener will be formed.

  

  

  In the field of fastener manufacturing, cold heading process is widely used because of its following characteristics:

  

  1. Cold heading process can be carried out at room temperature without heating metal materials.

  

  2. Cold heading process can reduce or replace cutting processing and improve material utilization.

  

  3. Cold heading machine models and series are complete, suitable for various bolts and nuts forming, equipment performance is reliable, high efficiency, stable quality.

  The cold heading process can improve the surface finish of the workpiece and ensure the accuracy of the workpiece, and can manufacture high-precision, high-strength bolts, nuts, etc.; the cold heading process can improve the mechanical properties of the workpiece, such as increasing the density and hardness of the material, thereby improving wear resistance and corrosion resistance. In general, the cold heading process can improve productivity, ensure the quality of fasteners, reduce material loss, and reduce production costs. It is increasingly widely used in the production of standard fasteners.

What Are the Methods to Prevent Loosening of Anti-loosening Nuts

  Anti-loosening nut is a nut, which is a part that is screwed together with a bolt or a screw for tightening. It is an original part required by all production and processing equipment. Anti-loosening non standard nut is a part that tightly connects mechanical equipment together. With the help of the inner thread, anti-loosening nuts and screws of the same specifications can be connected together. The following is a detailed introduction to several methods of preventing anti-loosening nuts from slipping.Even so, Non standard hardware factory We must also adhere to the quality of the industry and create unique products for the company. https://jieruifasteners.com/

  

  1. Anti-loosening of equipment

  

  It is to use the locking nut stopper to directly limit the relative rotation of the locking nut pair. For example, the use of tooth pins, serial wires and stop washers. Because the locking nut stopper does not have a pre-tightening force, the anti-loosening stopper can only work when the locking nut is loose and returned to the stop position. Therefore, the locking nut method does not actually prevent loosening but prevents falling.

  

  2. Riveting and anti-loosening

  

  After tightening, use punching, welding, bonding and other methods to make the locking nut pair lose the performance of the kinematic pair and the connection becomes an irremovable connection. The disadvantage of this method is that the bolt rod can only be used once, and it is very difficult to disassemble, and the bolt pair needs to be damaged before it can be disassembled.

  

  3. Friction anti-loosening

  

  It is the most widely used anti-loosening method. This method forms a positive pressure between the locking nut pairs that does not change with the external force, so as to form a friction force that can prevent the relative rotation of the locking nut pairs. This positive pressure can be achieved by axially or simultaneously pressing the locking nut pairs in two directions. For example, elastic washers, double nuts, self-locking nuts and insert locking nuts are used.

  

  

  4. Structural anti-loosening

  

  It is to apply the locking nut pair’s own structure, that is, the Tang’s locking nut anti-loosening method.

  

  

  5. Punching edge anti-loosening

  

  After the nut is tightened, the thread is destroyed by punching the end of the thread; bonding anti-loosening generally uses anaerobic adhesive to apply to the thread screw surface. After tightening the anti-loosening nut, the adhesive can solidify by itself, and the actual anti-loosening effect is better. The disadvantage of this method is that the bolt rod can only be used once, and it is very difficult to disassemble, and the bolt pair needs to be destroyed before it can be disassembled.

The Process of Customizing Non-standard Nuts

  Non-standard nuts have always been popular with users in the market. Because there is no fixed standard, non-standard nuts are customized according to customer needs and sizes. So what is the process of customizing non-standard nuts?So, I believe non-standard fasteners price In the future, it will be promising to create a miracle belonging to the industry. https://jieruifasteners.com/

  

  1. First of all, before customizing non-standard nuts, you should think about which product the non-standard nuts will be used on and what effect they will achieve on the product. Will they be injected into the product or will they serve as a connection between two products?

  

  custom non standard nuts.jpg

  

  2. Secondly, the appearance of non-standard nuts and the specifications, sizes, and patterns of non-standard nuts should be designed according to the needs of the product. The material and surface treatment of non-standard nuts should be determined in combination with the product and its use environment. Materials such as copper, iron, stainless steel, alloy, etc. Surface treatment processes such as galvanizing iron nuts or degreasing stainless steel nuts.

  

  non standard fasteners.jpg

  

  3. The drawings of non-standard nuts are generally designed by the demander, and the specifications, sizes and requirements of each part of the non-standard screws are marked on the drawings. If there is no drawing. As long as the product for non-standard nuts is provided, or the requirements for non-standard nuts are provided, the manufacturer can also design non-standard screws according to the actual situation.

  4. After the drawing is designed, proofs are made according to the size and specifications of the nut. If there are no problems with the sample production, mass production will be carried out according to the requirements of the nut.

China emphasizes that eliminating armed conflicts is the greatest protection for civilians

In the eyes of industry experts, ddos攻击 Indeed, it has great development potential, which makes many investors more interested.https://www.ddos444.com/

United Nations, May 21: Fu Cong, Permanent Representative of China to the United Nations, delivered a speech at the Security Council open debate on the protection of civilians in armed conflict on the 21st, emphasizing that the elimination of armed conflict is the greatest protection for civilians.

Fu Cong said that saving lives in armed conflicts is certainly a noble goal, but it must be noted that as long as the conflict does not subside, civilian lives will be threatened at any time. At the same time, we must not forget that the primary responsibility of the Security Council is to maintain international peace and security. The Gaza conflict, which has lasted for more than seven months, has caused unprecedented civilian casualties and humanitarian disasters, and the lives of the millions of people currently gathering for refuge in Rafah are at risk. The Security Council should make promoting an immediate and comprehensive ceasefire a top priority. To this end, further action should be taken to urge Israel to immediately stop collective punishment of the Palestinian people and stop advancing its military offensive against Rafah, so as to give the people hope for survival.

Fu Cong said that international humanitarian law is the bottom line that must be jointly observed. The Security Council should continue to safeguard the authority of international humanitarian law and ensure its universal and uniform application. Double standards and selective application of humanitarian law are unacceptable and are tantamount to condoning more illegal activities in disguise.

Fu Cong said that attention should be paid to responding to the outstanding challenges brought by the proliferation of small arms and light weapons and the development of autonomous weapon systems. China calls for strengthening global governance of the arms trade, combating the illegal transfer of small arms and light weapons, and calls on all countries not to provide weapons to non-state entities. The risks of artificial intelligence and autonomous weapon systems as means of warfare are rising and deserve great attention. Countries should adhere to the principles of putting people first and intelligence for good to ensure that artificial intelligence is always under human control. China supports the formulation of a legally binding international instrument around lethal autonomous weapon systems.

Fu Cong said that improving the governance capabilities of countries involved in conflicts is the fundamental solution. When dealing with conflict situations, the international community should take systematic measures to support countries parties to conflicts in effectively enhancing their national defense, public security and counter-terrorism capabilities. At the same time, it is necessary to help the countries concerned accelerate development and gradually resolve the deep-seated causes of conflicts. China is willing to continue to work with the international community to make unremitting efforts to eliminate the scourge of war as soon as possible and ensure the happiness and tranquility of the people.
