　　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).With the upsurge of industry development, non-standard fasteners price The expressive force in the market has also been very good, bringing many brand-new high-quality experiences to users. 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.

　　Progressive glasses can be used to see far, medium and near distances with one pair of glasses, which can solve the problem of “myopia and presbyopia”. The optical transition is smooth and there is no obvious discontinuity in the degree. However, the fitting requirements are high and the corresponding fitting parameters also require more precision. Among them, how to measure and select the progressive channel is a headache for many optical shops.In addition to these aspects, fashion sunglasses The performance in other aspects is also relatively good, which has attracted everyone’s attention and research. https://ymoeyewear.com/

　　

　　Nowadays, with the high penetration of the Internet, the middle-aged and elderly people have officially entered the era of small screens, and their eye health problems have been rapidly magnified. Adult progressive lenses can greatly meet the needs of presbyopic people to see both near and far with one pair of glasses.

　　

　　However, progressive glasses have high requirements for fitting, and how to accurately and quickly measure the key fitting parameters – channel and ADD, has troubled many colleagues in optical shops. At this year’s Shanghai exhibition, a very practical tool was discovered that can quickly and accurately measure the progressive channel.

　　

　　

　　What is a progressive channel?

　　

　　

　　Simply put, the channel is the transition length of the progressive lens from far to near. Proper channel selection is one of the key factors in whether the progressive lens is comfortable and convenient to wear.

　　

　　Note: The channel length of progressive lenses of different brands is different, so please ask clearly when ordering! Example: The channel length of Zeiss progressive lenses is the vertical distance from the fitting cross to the starting part of the near area.

　　

　　When the distance diopter and ADD are determined, the longer the channel length, the smoother the change from near diopter to distance diopter. However, when selecting a long channel, the downward rotation ability of the eye should be considered. Insufficient downward rotation force can easily cause unclear near vision.

　　

　　

　　Tools Recommendation | Rapid Calculation of Progressive Channel

　　

　　How to accurately measure the length of the progressive channel? Measure the position of the pupil on the support piece when using it for distance and near respectively, and then measure the vertical distance between the two.

　　For many girls, it only takes two brushes to paint eye shadow, but if you want to pursue a more perfect and clean makeup, you need to use all kinds of small brushes reasonably. Of course, two brushes can’t solve it. In addition, there is the color matching of eye shadow. Some young sisters may not know much about the rules of eye shadow matching. This article is just a little knowledge about the selection, use and color matching of makeup brushes ~ Then let’s get started ~From some points of view, makeup brush manufacturers It is the core driving force to better promote the rapid development of the surrounding markets. https://lsmakeupbrush.com

　　

　　First, choose an eye shadow brush

　　

　　Priming brush

　　

　　This brush with bristles of about one centimeter in length is the largest eye shadow brush, which is mainly used to make the whole eyelid bottom. The usage is to smudge the whole eye socket with light eye shadow.

　　

　　Color spreading brush

　　

　　Medium and small eye shadow brushes are used to superimpose other dark colors on the background color. The skill of using them is to bring colors from bottom to top. It is recommended to prepare two medium eye shadow brushes, one with light color and the other with dark color.

　　

　　Detail smudge brush

　　

　　This eye shadow brush looks the same as the base brush, but it is actually the smallest size. The bristles may be only about 3mm, which is used to superimpose the heavy colors at the end of the eyes, or to draw some dark colors into eyeliner.

　　

　　Contour brush

　　

　　This brush is bigger than the base brush. It can be used after painting the whole eye shadow, without any powder. It just sweeps the edge of eye makeup to make the color more natural without obvious edge feeling, and it can also be used to sweep the nose shadow.

　　

　　Eye shadow color

　　

　　If it is not necessary for special occasions, it is best not to use too many colors in an eye makeup.

　　

　　The background color means that the color of a large area of eye socket must be matte, not necessarily light, but it is best to be matte without flashing, which will make the whole eye feel less swollen.

　　

　　The color superimposed on the background color is called the theme color. You can choose a brighter color, and the smudge range is less than the background color. How to say this range? You need to practice more. If you are a girl with double eyelids, you should control it around two or three millimeters. The color that is aggravated in the triangle area at the end of the eye is called the finishing touch color ~ when sweeping the end of the eye, bring a little to the lower eyelid part of the end of the eye to make the eyes deeper.

　　

　　Finally, brighten the color, with sequins or flashing colors, embellish the eyes, eyes and lower eyelids, which can make the eyes more stereoscopic and deep ~
