In the fastener forming process, cold heading (extrusion) technology is a main processing technology, which belongs to the category of metal pressure processing. In production, at room temperature, external force is applied to the metal to form the metal in a predetermined mold. This method is usually called cold heading. In fact, the forming of any fastener is not only achieved by cold heading. In the cold heading process, in addition to upsetting deformation, it is also accompanied by positive and negative extrusion, compound extrusion, punching, rolling and other deformation methods. Therefore, the name of cold heading in production is just a habitual name. To be more precise, it should be called cold heading (extrusion).Under people’s attention Non standard hardware factory Finally grow into what people need, born for the market and come for the demand. https://jieruifasteners.com/

　　

　　

　　Cold heading (extrusion) has many advantages, and it is suitable for mass production of fasteners. Its advantages can be summarized as follows:

　　

　　1. High steel utilization rate. Cold heading (extrusion) is a method with little or no cutting. For example, when processing hexagonal bolts and cylindrical socket screws of rods, the steel utilization rate is only 25% to 35% by cutting, while the utilization rate can be as high as 85% to 95% by cold heading (extrusion), which is only some process consumption of the head, tail and hexagonal head edge.

　　

　　High productivity. Compared with general cutting, the efficiency of cold heading (extrusion) is more than dozens of times higher.

　　

　　2. Good mechanical properties. The strength of parts processed by cold heading (extrusion) method is much better than that of cutting because the metal fibers are not cut.

　　

　　3. Suitable for automated production. Fasteners (including some special-shaped parts) suitable for cold heading (extrusion) method are basically symmetrical parts, suitable for production by high-speed automatic cold heading machine, and are also the main method of mass production.

　　

　　In short, the cold heading (extrusion) method for processing fasteners and special-shaped parts is a processing method with a relatively high comprehensive economic benefit. It is a processing method commonly used in the fastener industry. It is also an advanced processing method that is widely used and developed at home and abroad.

　　

　　At room temperature, the blank is placed in the mold of an automatic cold heading machine or a press, and pressure is applied to the mold. The relative movement of the upper and lower molds is used to deform the blank in the mold cavity, reduce the height, and increase the cross-section. This pressure processing method is called cold heading for automatic cold heading machines and cold pressing for presses. In actual production, the cold forming process of fasteners is often accompanied by extrusion during the cold heading process. Therefore, the cold heading process of fastener products alone is actually a composite processing method that has both cold heading and extrusion.

　　As people become more aware of the damaging effects of plastic on the environment, many are looking for ways to reduce their reliance on single-use plastics. One way to do this is by switching to compostable trash bags. These bags are made from 100% plant-based materials and are designed to break down quickly under specific conditions, such as heat and moisture. While they may not be suitable for all types of trash, they can be a great alternative to plastic bags for items like food scraps and yard waste. And, since they break down into organic matter, they are actually good for the environment. So if you¨re looking for ways to reduce your plastic usage, consider switching to compostable trash bags.According to related reports, biodegradable dog poop bags To a large extent, it leads the changes of market conditions. https://biodegradable-gd.com

　　

　　1. How long does it take for biodegradable garbage bags to break down?

　　

　　Biodegradable trash bags are a better eco-friendly alternative because they break down faster than regular trash bags. For example, biodegradable trash bags take about three months to break down in hot conditions, and six months to break down in cooler temperatures with little moisture. However, biodegradable garbage bags are not always eco-friendly and sustainable for our planet.

　　

　　2. Do compostable bags biodegrade on their own?

　　

　　Compostable and biodegradable are often used interchangeably. However, there are major differences between the two. Biodegradable bags are usually still ordinary plastic bags that contain microorganisms to remove plastic particles. These microplastics may take some time to disappear. Compostable bags are made of compostable materials such as corn starch and do not contain harmful substances, making them a more environmentally friendly choice. When choosing between the two, it is important to consider the intended use of the compostable garbage bags.
