1. Reduce deformation Reduce the influence of processing stress on aluminum alloy deformation. Heat treatment after rough machining can greatly reduce the influence of stress on finish machining. 2. Improve accuracy Improve the accuracy and surface quality of aluminum profile machined parts. After heat treatment, finish machining is carried out. Because finish machining improves the machining accuracy on the basis of rough machining, the machining amount is relatively small, and the resulting deformation stress is also very small, so it can greatly improve the quality of aluminum profile machined parts. 3. Improve production efficiency. As long as enough machining allowance is reserved for finishing in rough machining, there is no need to consider the problem of dimensional tolerance too much. It can effectively improve the processing efficiency of various machine tools.

1. Stainless steel passivation, this process is recommended that the surface must be iron free. The presence of stainless steel particles on the surface of any iron, cast iron, low carbon steel, medium carbon steel or low alloy steel will promote the pitting of "free" iron and stainless steel on its surface. This is a very serious problem, so passivation is only used to deal with stainless steel and stainless iron. The main purpose of stainless steel passivation is to prevent the surface of stainless steel from oxidation and corrosion. 2. Stainless steel pickling The purpose of stainless steel pickling treatment is to remove the oxide scale on the surface of stainless steel after high temperature welding, heat treatment or hot processing. At the same time, it can also eliminate the red rust corrosion of steel or iron or steel particle pollutants. Please note that if the acid solution on the surface is not cleaned after pickling, the surface will soon start to rust and corrode. This leads to a reduction in the ductility of the underlying steel surface layer. Stainless steel pickling process can be applied to the surface treatment of all 200, 300 and 400 series stainless steels. All pickling operations result in a slight size change while removing impurities from the metal surface. Therefore, the result is that to a certain extent, an extinction of visual brightness may also be a significant reduction in size. Heat treatment in vacuum or a good controlled atmosphere, such as bright annealing, eliminates the need for pickling, which usually makes stainless steel get a better polished surface. 3. Degrease and degrease the stainless steel cleaning agent. The pretreatment of any process of stainless steel surface treatment must first remove grease, cutting fluid, drawing compounds and other lubricants, and then passivation treatment before surface heat treatment of stainless steel parts can be carried out. Stainless steel parts must also be further welded before degreasing treatment to prevent carbon in the picker at high temperature. Usually, stainless steel cleaning agent is used. It only needs to soak at room temperature for 1-8 minutes to remove any oil stain. It has simple operation, low labor intensity, and can be recycled repeatedly, effectively reducing production costs. In the cleaning operation with other metals, the cleaning rate can be increased by using brushing, spraying or stirring.

Summary and classification of common plastic surface treatment agents: 1、 Frosting Frosted plastic generally refers to plastic film or sheet. When extruding the formed sheet, there is a frosted pattern on the surface of the forming roller, so that the frosted pattern will naturally form in the process of plastic cooling. This method is simple and fast, especially for transparent products 2、 Polishing Using mechanical, chemical or electrochemical functions to reduce the surface roughness of the workpiece, so as to obtain a bright and flat surface. Plastic products are usually rolled up with frosted paper to polish plastic products, which is usually the first step before spraying! 3、 Spraying Plastic spraying is mainly to apply a layer of plastic paint on metal equipment or plastic products, and then coax them to dry. Generally, it is dried for about 10 minutes. Thanks to the progress of paint, to achieve the same effect, there is no need to paste paper as before. Spray paint can isolate the air, and spray paint is an insulator, so it can play the role of anti-aging and anti-static of plastic products. The most important thing is to have the appearance effect that plastic products themselves do not have 。 In the spraying process of plastic surface, the effective method to solve the problem of poor adhesion between substrate and coating and paint falling off is Jingchuan chemical adhesive treatment agent, which improves the adhesion between substrate and coating and solves the problem of paint falling off, with an adhesion of 5B. 4、 Silk screen printing The printing plate is usually square and in a fine mesh. During printing, the ink on the printing plate leaks from the through hole of the plate to the substrate under the extrusion of the ink scraper. There are many kinds of materials for making screen version, such as nylon (PA), polyacetic acid (CA), silk or metal mesh. If PC (polycarbonate) adopts this surface treatment, the color performance will be very ideal. 5、 Pad printing First, the designed pattern is etched on the printing plate, and then the etched plate is coated with ink, and then most of the ink is transferred to the printed object through the silicone head. 6、 Heat transfer printing The pattern is pre printed on the surface of the transfer film, and the exquisite pattern on the transfer film is transferred on the product surface through one-time processing (heating and pressurization) of the heat transfer machine. After forming, the ink layer and the product surface are dissolved into one, which is lifelike and beautiful, and greatly improves the grade of the product. However, due to the high technical content of this process, many materials need to be imported. Heat transfer process is applied to the surface of various ABS, PP, plastic, wood, coated metal and other products 7、 Water transfer: It is a kind of printing that uses water pressure to hydrolyze the transfer paper / plastic film with color patterns. 8、 Laser engraving The energy of laser is used to treat the surface into a "trace", exposing a layer of material under the surface, which can be engraved or patterned as needed. 9、 Electrophoresis (water electroplating) One of the metal electrodeposition technologies, which usually uses chromium, zinc and other metals to obtain a deposition layer on the surface of the workpiece by electrochemistry. The plastic parts have a metallic texture outside, and the materials are corrosion-resistant and wear-resistant, with decorative and electrical, magnetic and optical properties. ABS and PC are common materials in the electroplating process. However, during the injection molding process, if mold release agent or mold oil stains are used on the surface of the material, resulting in oil spots, oil pits and oil spots, the effective solution is Jingchuan chemical electroplating oil stain treatment agent to cover the oil stains on the surface of the material, replace white oil immersion cleaning, improve the adhesion, and solve the problems of oil spots, oil pits and oil spots. 10、 Vacuum coating In the vacuum chamber, the atoms of the material are separated from the heating source and hit the surface of the plated object. This method can obtain a dazzling effect, which is suitable for ABS and PC plastic products. At the same time, because of its complex process, high requirements for environment and equipment, it is generally suitable for large quantities of products. 11、 Biting (pitting, dermatoglyphics) for plastic molds Concentrated sulfuric acid is used to corrode the inside of the plastic forming mold, forming snake lines, etched lines, ploughing, wood lines and other forms of lines. After the plastic is formed through the mold, the surface has corresponding lines.

Electroplating is the most commonly used means of surface treatment, and its main purpose is for beauty and corrosion prevention; Electroplating is to add another layer of metal on the metal surface, so the size of the workpiece surface will change. The common types of electroplating are as follows: tin plating - mainly iron tin plating, because iron doesn't eat tin very much, it's inconvenient to take tin for welding. After tin plating, this problem is solved, but the anti rust ability is not good (tin is easy to oxidize, and it will turn black after oxidation, which is very ugly). Nickel plating - the workpiece after nickel plating is bright, beautiful and has strong rust prevention ability; It's not good to take iron directly to nickel plating, because iron doesn't eat nickel very much. After electroplating, the container peels and falls off. Generally, it's better to nickel plating after plating a layer of copper on the surface of iron parts, and it can shield the electric field and magnetic field together.

In a word, in the process of aluminum profile customization, aluminum profile manufacturers will provide corresponding service solutions according to the needs of users, formulate more professional and better product production standards according to the needs of users, and make improvements according to their own technical models and customization requirements in the production process; The customized process of aluminum profile makes the integrity and creativity of product structure modeling bring outstanding application effects.

Like plastic manufacturing, metal manufacturing largely depends on the type and grade of metal used in production. Some of the more commonly used metals include steel, magnesium, iron, aluminum, copper and nickel, each of which has a different grade. Compared with plastic manufacturing, metal usually has the following advantages: Heat resistance: metals usually have a high melting point and are unlikely to degrade at high temperatures. Strength improvement: the metal brand is stronger, harder and more durable than the plastic brand. Versatility: metals can be manufactured through a wider range of processes, including casting, deep drawing, welding, forging, brazing and chip cutting. Cost effectiveness: metals are usually a cost-effective option, especially in mass or long-term production. Although metal processing has many advantages, metal is not the ideal choice for every application. Some disadvantages of metal manufacturing include: Auxiliary operations: metal processing is more likely to require post-processing processes, such as finishing, painting and deburring, which are time-consuming and expensive. Design limitations: the viscosity and melt flow behavior of some metals are not suitable for machining highly complex geometries or shapes. High start-up costs: metal tools are usually more expensive than similar plastic manufacturing tools.  

Although the results of plastic manufacturing largely depend on the unique characteristics of the type of plastic used (acrylic, plexiglass, nylon, etc.), the process itself has several advantages Easy to form: compared with other materials, plastic can be made into basic and complex geometric shapes relatively easily due to its low melting point and high ductility. Reduced surface treatment: unlike most metals, plastics can be colored before manufacturing, eliminating the need for some post-treatment processes, such as painting. Faster production: plastic manufacturing usually involves fast cycle time and fast turnover. Lighter weight: plastic is usually lighter than metal of the same size. Chemical resistance: compared with metals, plastics are usually less susceptible to damage by chemicals or chemical reactions (such as oxidation or rust). Although plastic can be used to make various parts, as a production material, it also has its limitations. Some disadvantages of plastic manufacturing include: Limited wear resistance: for high temperature, acidity and other corrosive elements, the resistance threshold of plastics is low. Structural disadvantages: most plastics are not suitable for applications requiring high structural strength, such as heavy equipment components and most building materials.

1. Passivation is a method to change the surface of metal into a state that is not easy to be oxidized and delay the corrosion rate of metal. An active metal or alloy in which chemical activity Passivation refers to the appearance of greatly decreasing sex and becoming a precious metal state. 2. Anodic oxidation: refers to the process of plating a thin layer of other metals or alloys on the surface of some metals by using the principle of electrolysis. Brush plating is used for local plating or correction. Barrel plating is used for small parts, such as fasteners, washers, pins, etc. After electroplating, it can obtain protective decoration and various functional appearance on the finished mechanical products Layer, it can also correct worn and machined workpieces. Electroplating solutions include acidic, alkaline and acidic and neutral solutions with chromium agents, regardless of the choice The three plating methods should be universal to a certain extent with the finished products to be plated and the plating bath, hanging tools, etc. 3. Spraying: used for external protection of equipment Decoration is usually carried out on the basis of oxidation. Aluminum profiles should be pretreated before coating to make the coating firmly connected with the workpiece. There are usually three kinds Method: (1) Phosphating (phosphate method), (2) Chrome (chrome free), (3) Chemical oxidation. 4. Sandblasting, the primary effect is appearance finishing. Sandblasting before painting (painting or plastic spraying) can add surface roughness, which has a certain contribution to the improvement of adhesion, but Limited contribution, not as good as chemical coating pretreatment. 5. Chemical oxidation: the oxide film is thin, about 0.5 ~ 4 microns thick, porous, soft, and has excellent adsorption, which can be used as the bottom layer of organic coating, However, its wear resistance and corrosion resistance are not as good as anodic oxide film 6. The chemical oxidation technology of aluminum and aluminum alloys can be divided into two categories: alkaline oxidation method and acid oxidation method according to the nature of its solution. According to the properties of the film, it can be divided into: oxidation Material film, phosphate film, chromate film, chromic acid phosphate film. Conductive oxidation (chromate conversion film) - used for both protective and conductive occasions. 7. Coloring: there are two main technologies for coloring aluminum: one is aluminum oxidation coloring technology, and the other is aluminum electrophoresis coloring technology. On the oxide film Various colors are formed to satisfy the application requirements. For example, optical instrument parts are often black, and commemorative medals are golden yellow. 8. Chemical polishing is the selective self dissolving effect of aluminum and aluminum alloy in acid or alkaline electrolyte solution to level and polish the surface of the year, The following chemical processing methods are used to reduce the surface roughness and pH. This polishing method has simple equipment, no power supply, and is not constrained by the external dimensions of the workpiece , high throwing speed and low processing cost. The purity of aluminum and aluminum alloy has a great influence on the quality of chemical polishing. The higher its purity is, The better the polishing quality is, the worse it is. 9. Electrochemical oxidation. The chemical oxidation treatment equipment for aluminum and aluminum alloys is simple, easy to operate, high production efficiency, no power consumption, and wide application range, It is not constrained by the size and shape of the part. The thickness of oxide film is about 5 ~ 20 microns (the thickness of hard anodic oxide film can reach 60 ~ 200 microns), with a high Hardness, excellent heat resistance and insulation, corrosion resistance higher than chemical oxide film, porous, excellent adsorption ability.

1. Surface drawing treatment Metal wire drawing is a very common decorative method in life. It can be made into straight lines, threads, ripples, random lines and spiral lines. This surface treatment has the characteristics of good hand feel, fine luster and strong wear resistance. 2. Spraying Stainless steel spraying is substantially different from the coloring treatment above. Due to different materials, some spraying may damage the oxide layer on the surface of stainless steel. Spraying can use a simple process to achieve different colors of stainless steel products, and can also use different spraying to change the feel of stainless steel. 3. Mirror treatment The mirror treatment of stainless steel is simply to polish the surface of stainless steel. Through seven process steps of rough grinding, secondary rough grinding, semi fine grinding, fine grinding, secondary fine grinding, semi polishing, and polishing, repeatedly polish with different abrasive belts, hemp wheels, and cloth wheels, and finally obtain the mirror effect of ordinary polishing, ordinary 6K, fine grinding 8K, and super fine grinding 10K. The mirror gives people a high-end, simple and fashionable feeling. 4. Surface coloring the surface coloring process of stainless steel can bring different colors to stainless steel, making the metal more colorful. Coloring not only enriches stainless steel in appearance, but also effectively improves the wear resistance and corrosion resistance of products. The commonly used surface coloring methods mainly include: chemical oxidation coloring, electrochemical oxidation coloring, ion deposition oxide coloring, high temperature oxidation coloring, gas phase cracking coloring, etc. For example, in the titanium plating process of stainless steel, titanium, zirconium and other metals are discharged in the glow of inert gas to ionize the metal vapor, and the metal ions are accelerated to precipitate on the negatively charged stainless steel plate through the electric field, forming a bright and colorful metal film. Stainless steel titanium plated decorative parts can not only show rich and gorgeous colors, greatly improve the visual and environmental adaptability of the building, but also have corrosion resistance, oxidation resistance, good plasticity and excellent cleanability. They have become the first choice of more and more decoration customers. 5. Sand blasting is a common surface treatment process for stainless steel processing. It is mainly the power obtained by compressing the air. The high-speed jet beam sprays the spray material onto the surface of the workpiece to be treated, so that the plate surface presents a fine bead sand surface. After sandblasting, the surface structure is uniform, which can create the low-key and durable features of the product, and the production and processing efficiency is high.

1. High compressive strength Copper is the profile of copper raw material, which is characterized by copper. This type of copper has high strength, can maintain a stable structure when applied, and is not easy to suffer external influence in terms of structure. 2. Good patience Due to the characteristics of copper, copper profiles have good resistance, and it is not easy to deform and destroy under the influence of external forces when applied. With this advantage, this type of copper can have a very good performance in long-term application. 3. Good ductility With good ductility, copper profiles can resist the negative effects of external forces and avoid the effects of external forces when applied. This type of copper can show a stable and firm application effect. 4. Firm structure With the characteristics of high compressive strength and good resistance, the overall structure of copper profile must be very appropriate. Such a structure can be used stably and reliably, and always play its role normally. 5. Long service life Because of its excellent characteristics and many advantages and functions, copper profiles can effectively avoid the negative effects of various external factors when applied, so copper profiles will have a long service life.
