Preface With the continuous progress of fiber laser technology and the continuous decline of laser processing cost, there is an obvious trend in the sheet metal processing market, that is, gradually transfer the products below the medium batch originally used for stamping by NC punch to NC laser cutting machine. However, people in the industry also clearly realize that NC punch still has its irreplaceable advantages, which are mainly reflected in the following points: sheet metal processing combined with NC stamping; Large quantities of non cutting and punching sheet metal processing; Sheet metal processing with dense mesh. At present, these…

Taking metal or alloy parts as anodes, oxide films are formed on their surfaces by electrolysis. Metal oxide film changes the surface state and properties, such as surface coloring, improving corrosion resistance, enhancing wear resistance and hardness, protecting metal surface and so on. The thin layer of oxide film has a large number of micropores, which can absorb various lubricants and is suitable for manufacturing engine cylinders or other wear-resistant parts; The membrane has strong microporous adsorption capacity and can be colored into various beautiful and gorgeous colors. Non ferrous metals or their alloys (such as magnesium, aluminum and their…

During printing, through the extrusion of the scraper, the ink is transferred to the substrate through the mesh of the picture and text part to form the same picture and text as the original. Screen printing equipment is simple, easy to operate, simple printing and plate making, low cost and strong adaptability. Screen printing has a wide range of applications. Common printing materials include: color oil paintings, posters, business cards, binding covers, commodity signs, printing and dyeing textiles, etc. In the machining industry, everyone must be familiar with silk screen printing. But what are the advantages and characteristics of silk…

Water transfer technology is a kind of printing that uses water pressure to hydrolyze the transfer paper / plastic film with color pattern. With the improvement of people's requirements for product packaging and decoration, water transfer printing is used more and more widely. The principle of indirect printing and perfect printing effect solve the problems of surface decoration of many products. Process flow of water transfer printing: making water transfer paper → soaking the paper → pattern transfer → drying → finished product 1. Production of water transfer printing paper: the negative film is output for printing plate after computer…

Painting is the general name of surface coating processing of industrial products. Painting processing is generally used for plastic Painting, silk screen printing and pad printing processing; Color modification and silk screen printing of EVA, rubber and other shoe materials. An injector is required to complete the process operation. You can choose oil spray matte, semi matte, high gloss, etc. according to your needs. Why Painting? The Painting on the surface of the hand board can make it more beautiful. To some extent, the Painting effect reaches the extreme, which can make consumers have a better visual impact and promote…

Strictly speaking, sand blasting is a kind of skin texture, which can be divided into two effects: concave convex effect and concave convex effect. The hand mold sandblasting is also powered by compressed air to form a high-speed jet beam to spray the sprayed materials (copper ore, quartz sand, emery, iron sand and sea sand) to the surface of the workpiece to be treated at high speed, so as to change the appearance or shape of the workpiece surface. Due to the impact and cutting effect of abrasive on the surface of hand board workpiece, the surface of hand board…

Polishing refers to the processing method of reducing the surface roughness of the workpiece by mechanical, chemical or electrochemical action, so as to obtain a bright and flat surface. Hand polishing can not improve the dimensional accuracy or geometric accuracy of the workpiece, but for the purpose of obtaining smooth surface or mirror gloss, and sometimes used to eliminate gloss (extinction). There are many kinds of hand polishing materials, which are generally divided into: polishing wax, polishing cloth wheel, nylon wheel, hemp wheel, thread wheel, wind wheel, miscellaneous cloth wheel, etc. Different workpiece polishing has different polishing processes, and different…

Laser engraving, also known as laser engraving or laser marking, is a surface treatment process based on the optical principle. It is mostly used on the keys of mobile phones and electronic dictionaries. It carves traces through the chemical and physical changes of surface substances caused by the light energy of laser beam, or burns some substances through the light energy to show the graphics and characters to be etched. According to different engraving methods, it can be divided into dot matrix engraving and vector cutting. 1. Dot matrix engraving: similar to high-definition dot matrix printing; The laser head swings…

The term "wire drawing" may be unfamiliar to many laymen, but I believe most people have seen common products made by wire drawing. For example, aluminum thermos bottles, aluminum bowls and aluminum windows have been treated with wire drawing technology. So, what is wire drawing and how is it made? Wire drawing is a kind of metal processing technology. In metal pressure machining, the metal is forced through the die under the action of external force, the metal cross-sectional area is compressed, and the required cross-sectional area shape and size are obtained. The technical processing method is called metal wire…

We know that metal products are easy to be corroded. In order to prolong the service life of metal products and improve the anti-corrosion ability of metal products, passivation protection must be carried out. Our common metal objects such as ships and cars are passivated. Passivation is a method to change the metal surface into a state that is not easy to be oxidized and delay the corrosion rate of metal. In addition, an active metal or alloy, in which the chemical activity is greatly reduced and becomes a precious metal state, also known as passivation. If the corrosion products…
