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…

Electroplating is often mentioned in the production process of hand board. It is a commonly used surface treatment technology in hand board production. Then, what is the role of electroplating technology in hand board manufacturing? Electroplating is the process of plating a thin layer of other metals or alloys on the metal surface using the principle of electrolysis. The purpose of electroplating is to coat the metal coating on the substrate and change the surface properties or dimensions of the substrate Electroplating can enhance the corrosion resistance of metal (the coating metal mostly adopts corrosion-resistant metal), increase hardness, prevent abrasion,…

Full CNC process? die-casting? CNC + die casting? Before restoring the manufacturing journey of mobile phone shell, let's clarify several concepts: full CNC process and die-casting process, and CNC + die-casting. The middle frame of full CNC mobile phone is milled into a specific shape through the CNC machining center. Die-casting is to use the mold cavity to apply high pressure to the molten metal and die-casting the fluid metal into a solid metal shell or middle frame, Of course, there is the practice of combining the two processes. Think about it with the appendix. The cost of full CNC…

A car is composed of more than 10000 parts and components. Each part must be processed and formed through different processes before it can be assembled on the car. Today, let's take a look at the processing technology of seven auto parts. 1. About casting Casting is a production method in which molten metal is poured into the mold cavity, cooled and solidified to obtain products. In the manufacturing process of various parts, such as the cylinder body and the brake drum, many parts are made of cast iron, accounting for about 10% of the total weight of the vehicle…
