Aluminum alloy is a kind of alloy material with aluminum as the main component. Aluminum rods can be hot melted and extruded to obtain aluminum profiles with different cross section shapes. The production process of aluminum profiles mainly includes three processes: melting and casting, extrusion and coloring. However, coloring mainly includes oxidation, fluorocarbon spraying, powder spraying and other processes. So today, we will focus on the oxidation in aluminum profile painting to explain the precautions after aluminum profile processing. CNC processing of aluminum alloy parts 1、 Four points are required after aluminum profiles are processed and oxidized: 1. Rinse with hot water. The purpose is to age the film, but the water temperature and time must be strictly controlled. The appropriate temperature and time range is: temperature 40~50 ℃, time 0.5~1MIN. 2. Aging. The aging method of aluminum profiles can be determined according to the weather conditions. As long as it is sunny and can be exposed to the sun, it can be baked in an oven in rainy days or in winter. However, the processing conditions of aluminum profile shall be: temperature 40~50 ℃, time 10~15min. 3. Drying. It is better to air dry naturally. The workpiece flushed with hot water is hung on the shelf obliquely, so that the free water on the surface of the workpiece flows down in the straight direction. The water drops flowing to the lower corner shall be absorbed with a towel, and then the color of the film dried in this way will not be affected, which is very natural. 4. Unqualified and repaired parts. Unqualified conductive oxide film parts should be picked out before drying and aging processes, because it is difficult to remove the film layer after drying and aging and will affect the surface roughness of aluminum profile workpiece. Post treatment of aluminum profile after oxidation and blackening

A set of high-quality plastic molds requires not only good CNC processing equipment for plastic molds and skilled mold makers, but also good mold design. Especially for complex molds, the quality of mold design accounts for more than 80% of the mold quality. An excellent mold design is to make the processing cost low, the processing difficulty small and the processing time short on the premise of meeting the customer's requirements. What are the CNC processing procedures for plastic molds? CNC Processing of Automobile Plastic Mold 1、 CNC processing flow of plastic mold: 1.

Principle of plastic mold processing reservation ① For workpieces requiring heat treatment, 0.25mm grinding machine allowance shall be added on one side of the overall material preparation size before heat treatment; ② For the part of the mold core and insert that needs CNC rough machining, 0.2mm allowance shall be reserved on one side; ③ One side allowance of 0.3-0.5mm shall be reserved for rough milling of the contour by bench milling machine. For workpieces to be machined by grinder after line cutting, 0.05mm shall be reserved on one side of the forming part, and 0.1mm grinding allowance shall be reserved on one side of the contour opening; ④ Mirror polishing is required after CNC finishing and electric pulse, and 0.03mm polishing allowance is left on one side. 2. Requirements for processing accuracy of plastic moulds The manufacturing accuracy of die size shall be within 0.005~0.02mm; The perpendicularity shall be within the range of 0.01~0.02mm; Coaxiality shall be within 0.01~0.03mm; The parallelism of the upper and lower planes of the movable and fixed mold parting surfaces shall be within the range of 0.01~0.03mm. After the mold is closed, the gap between parting surfaces is less than the overflow value of the molded plastic. The parallelism of other formwork mating surfaces shall be within the range of 0.01~0.02mm; The fitting accuracy of the fixed part is generally within the range of 0.01~0.02mm; If the small core has no requirements for insertion or has little impact on the size, a clearance fit of 0.01~0.02mm on both sides can be adopted; The fitting accuracy of sliding part is generally H7/e6, H7/f7 and H7/g6. Note: If there is an insert on the mirror surface that is attached to a step, the fitting should not be too tight, otherwise, when the insert is knocked back from the front, the tool used for knocking is easy to damage the mirror surface. If it does not affect the product size, the bilateral clearance of 0.01~0.02mm can be used for fitting.

Non standard parts do not meet the multi-level requirements and special development of product production in accordance with the unified standards and specifications of the industry. Its appearance or performance does not belong to the national equipment product catalog, and its development cost and cycle time will be correspondingly higher than those of standard parts. What is the customized processing of non-standard parts? Non standard part processing is a manufacturing process, including a group of non-standard part forming operations by removing materials (by removing chips or by wearing) through machining mechanical equipment such as CNC lathes. Processing of non-standard auto parts 1、 What is customized processing of non-standard parts: The processing of non-standard parts requires the use of special industrial machinery dedicated to the processing of non-standard parts to process and transform the shape and size of non-standard parts. The processing method of non-standard parts will adopt two different processing methods according to the type and nature of objects. All metal non-standard parts (except castings) have experienced at least one metal forming operation at a certain stage in their manufacturing process, and often require multiple different operations. Metal forming theory can help determine how to use machine tools and equipment in a more effective way and improve productivity. What are the customized processing equipment for non-standard parts? Processing of non-standard auto parts 2、 Five categories of customized processing equipment for non-standard parts: 1. Welding equipment: mainly butt welding machine and argon arc welding machine. 2. Cutting equipment: including grinding wheel cutting machine, air plasma cutting machine, and angle grinder. 3. Processing machinery and equipment: bending machine, cutting machine, bending machine and punch. 4. Other equipment: air compressor, grinder, and some painting equipment. Non standard parts can be processed by manual, semi-automatic or automatic machine tools, but the processing work is carried out by mechanical equipment, with necessary motors and mechanisms. The classic non-standard parts processing machine tools are CNC drilling machines: the workpiece is fixed on the drill floor of the CNC drilling machine, and the CNC drilling machine performs rotary cutting movement and linear feed, and processes holes or drill depth with the same diameter as the drill in theory and the required size. There is also a file machine tool. The file machine tool is used to process with the blade installed on the punch tool holder. The blade conducts linear cutting movement on the workpiece fixed on the workbench. The workpiece has a forward movement perpendicular to the cutting movement. The whole process of non-standard parts processing requires very strict professionalism. Because only with such precise and strict requirements can non-standard parts be processed into non-standard parts, making the products processed with non-standard parts more accurate. Automobile parts processing Another type of machine tool for machining non-standard parts is the CNC machining center, which is different from the CNC milling machine in that the machining center has the ability to automatically exchange processing tools. By installing tools for different purposes on the tool magazine, you can change the processing tools on the spindle through the automatic tool change device in one clamping process to achieve multiple processing functions.

Aluminum alloy has the characteristics of low density, high strength, corrosion resistance, etc. Its portability and strength make aluminum alloy widely used in the processing and manufacturing of various parts. What are the five common methods for processing aluminum alloy accessories? Processing of aluminum alloy parts 1、 Five methods for processing aluminum alloy accessories: 1. Stamping of aluminum alloy parts Stamping refers to the forming and processing method of workpieces that can produce plastic deformation or separation by exerting external force on plates, strips, pipes and profiles through presses and dies according to the shape and size of the required workpieces. 2. Machining of aluminum alloy parts It mainly uses general machine tools such as vehicle, milling, planing, drilling and grinding to process mold parts and assemble them into various molds. Machining of aluminum alloy parts can also be called CNC precision machining or automatic lathe machining, CNC lathe machining, etc. 3. Precision casting of aluminum alloy parts Parts obtained by this method generally do not need to be machined. The shape and casting precision of precision casting are higher than those of traditional processing methods. 4. Powder metallurgy of aluminum alloy parts Powder metallurgy is a technology that uses metal powders as raw materials to produce materials or products through mixing, molding and sintering. 5. Injection molding of aluminum alloy parts The solid powder and organic binder are uniformly mixed, granulated, heated and plasticized, and then injected into the mold cavity with an injection molding machine for curing and molding. The binder in the preform is removed by chemical or thermal decomposition methods, and the final product is obtained by sintering and densification. Processing of aluminum alloy parts 2、 Three characteristics of aluminum alloy parts processing: The aluminum profile processing process includes three whole processes: melting, extrusion and coloring (coloring key includes: oxidation, electrophoresis process, fluorocarbon painting, electrostatic powder spraying, wood grain transfer printing, etc.). Processing characteristics of aluminum alloy parts: 1. Low processing hardness of aluminum alloy Compared with titanium alloy and quenched steel, aluminum alloy has lower hardness. Of course, heat treated or die cast aluminum alloy also has higher hardness. Generally, the HRC hardness of aluminum plate is below HRC40. Therefore, in the case of aluminum alloy processing, the tool load is small. In addition, aluminum alloy has excellent thermal conductivity, so the cutting temperature of aluminum alloy milling is low, which can improve the milling speed. 2. Low plasticity in aluminum alloy processing Aluminum alloy has low plasticity and low melting point. When processing aluminum alloy, the bonding edge problem is very deep, the chip removal performance is poor, and the surface roughness is also high. In fact, the main reason for processing aluminum alloy is that the effect of knife and roughness is not good. If the two problems of fixed blade and quality of machined surface are solved, the problem of aluminum alloy machining can be solved. 3. Aluminum alloy processing tools are easy to wear Due to the use of unsuitable tool materials, when processing aluminum alloys, tool wear is accelerated due to problems such as rod edge and chip discharge. Aluminum alloy CNC processing manufacturer Xiao Bian believes that you have a certain understanding of the aluminum profile processing process and aluminum alloy processing characteristics. In addition, if we choose aluminum alloy CNC processing manufacturers, we must choose qualified CNC processing manufacturers to have a good CNC processing service experience.

How do you know stamping parts? To simply understand the stamping parts, sheet metal processing companies are called stamping parts through hardware stretching. Sheet metal chassis can also process various types of industries. Generally, there are many stamping parts in the hardware industry. These stamping parts are numerous in the modern manufacturing industry, as well as in the automobile industry, but mainly stretching. There are many automobile factories, tractor factories and aircraft manufacturing industries. General profile steel forming die is composed of upper and lower templates, gaskets, punch, female die and die handle. Hardware, stamping parts, plastic products manufacturing, processing, etc. For example, the body, frame, carriage and body of a truck are all made of steel plates through stamping and welding. The materials used for stamping shall not only meet the technical requirements of design, but also meet the requirements of stamping process and subsequent process requirements. Stamping accessories Common metal stamping plates include low titanium alloy, carbon steel, stainless steel, aluminum, copper and their alloys. Stamping parts are widely used in various fields of our life, including some electronic components, auto parts, decorative materials, etc. Generally speaking, stamping refers to cold stamping of parts. For example, if you want to turn an iron plate into a fast-food plate, you need to design a set of molds. The working surface of the mold is the shape of the plate. Press the iron mold to make the plate you want. This is cold stamping, which is to directly use the mold to stamp metal materials.

Sheet metal processing is anything. These requirements may vary in size, shape, design, etc. With the help of advanced technology in the market, we can perfectly meet any specific requirements of customers, and spend less time. Sheet metal processing is the key technology that sheet metal technicians need to master, and it is also an important process of sheet metal product molding. It includes not only traditional cutting, blanking, bending and other methods and process parameters, but also various cold stamping die structures and process parameters, various equipment working principles and operating methods, as well as new stamping processes and new processes. It is generally divided into large sheet metal and small sheet metal. The large sheet metal is the power distribution cabinet, and the tolerance is generally 0.5-1mm. Small sheet metal requires high precision, about 0.2-0.5. This is also a customization requirement. Customized sheet metal Customized sheet metal processing is a kind of processing with complex structure. Its production and processing are generally completed through the processes of material preparation, lofting and cutting blank content, forming and assembly. As the cold processed sheet metal needs to go through the combination of processing and welding, metal cutting, heat treatment and inspection to form a complete product manufacturing process, its processing process often includes the above processing process content, Simple and solid structure, which can reasonably meet customers' requirements for products; It provides design, production, on-site construction and other one-stop services for large, medium and small enterprises, and welcomes new and old customers to make customized drawings. In sheet metal processing, laser punching technology can basically realize the function of laser cutting machine and truly change the traditional sheet metal processing technology. Realizing the real unmanned operation, greatly improving the efficiency, of course, the processing effect is also very good. Of course, the application of this technology needs further research. skill comes from practice. In order to improve efficiency, we must learn technology well. The laser drilling technology has greatly developed the entire sheet metal economy, which has significantly improved the drilling technology to a higher level, and the processing effect is significant.

First of all, there are many kinds of products that need sheet metal processing companies in the industry. In the face of these sheet metal chassis processing, professional factory equipment is also needed. Naturally, professional equipment manufacturers must have better quality. Zesi Hardware has its own advantage in sheet metal case processing. After all, we are also a professional manufacturer. For parts produced in large quantities and customized special materials, the required size and processing accuracy should also be taken into account. The more complex and precise the parts are, the higher the processing cost will be. The processing fees of each processing plant are somewhat different, so we still need to go to the processing plant to understand more clearly. General sheet metal processing cost includes drawing design cost, material cost, processing cost, surface treatment cost, etc. Sheet metal chassis The sheet metal processing technology includes the traditional cutting, blanking, bending and forming methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operating methods, as well as new stamping processes and new processes. The entire production process is complex. In fact, most of our sheet metal processing quotations are based on our experience. If the production process is complex and the customer's production cycle is tight, the quotation will be slightly higher. Product tax unit price=(material cost+processing cost+surface treatment cost+external component cost) * loss+packaging and transportation cost+project cost+profit.

The commonly used materials for sheet metal processing include cold rolled plate (SPCC), hot rolled plate (SHCC), galvanized plate (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum plate (6061, 5052, 1010, 1060, 6063, duralumin, etc.), and stainless steel (mirror surface, wire drawing surface, fog surface), which are selected according to different materials. High efficiency cutting technology combined with advanced functional features expands the scope of application and reduces the cost of single piece processing. If the proper automatic handling device is added to these laser cutting systems at the right time and connected to the storage system, the productivity can be further improved significantly. A similar effect can be achieved in the bending area. At this stage, the real economy has been greatly impacted. The cost of commodity production and processing should be spent on the cutting edge. So it is particularly critical to choose a high-quality sheet metal processing factory. The continuous output power of a sheet metal processing company can reach the order of kW to 10kW, so precision sheet metal processing is suitable for both finishing and large-scale material processing. Sheet metal processing company The precision sheet metal processing beam is easy to control: it is easy to combine with precision machinery, precision measurement technology and electronic computer to achieve high processing automation and high processing precision. The processing problem of precision sheet metal parts is often a welding problem. When a product is very small, we can use some corresponding welding methods to build it. When any product is manufactured, spraying can be divided into three situations. One is flat spraying, which can also be divided into mirror smooth and low-quality smooth. The spraying effects of the two skills are very different. The advantages of flat spraying are that it is beautiful, and the effect after printing is good, However, the price will be higher, the process will be more complex, and it is easy to scratch and difficult to maintain.

The shape and size of stamping materials are expansion stamping parts. Dongguan metal stamping parts are introduced to everyone, which is the premise for analyzing the deformation degree of stamping parts, designing processes and formulating process procedures. If the shape of the sheet is suitable, it can not only significantly improve the uneven distribution of deformation along the sheet, but also increase the forming limit, reduce the lug height and reduce the trimming allowance. Stamping can obtain complex shapes, which is difficult to be completed by other process methods. The stamping process of carbon steel and stainless steel is often used for equipment shells, components, boxes, etc., but because of its strong stiffness, stamping oil is usually used to improve the process. In order to meet the precision requirements of stamping parts, it is necessary to determine the number of processes through stamping process, because it is not only related to material properties, drawing height, drawing ladder number and other factors, but also related to drawing diameter, material thickness and so on. Stamping accessories Stainless steel plate is easy to harden, so high film strength and anti sintering tensile oil are required. Stamping oil with sulfur and chlorine compound additives is generally used to ensure extreme pressure performance and avoid burrs and cracks of workpiece. A specific shape is formed by a press that provides the pressure required for processing. Metal stampings are widely used in various fields of our lives, including some electronic components, auto parts, decorative materials, etc. The processing of stamping parts includes blanking, bending, drawing, forming, finishing and other processes. Build hardware and security provisioning. Most hardware products are not consumer goods. It is used as a supporting product of industrial manufacturing, semi-finished products and tools used in the production process.

In the hardware industry, many of our customers may encounter such a problem: tolerance requirements for sheet metal processing? The dimensional tolerance of sheet metal processing refers to the level to determine the accuracy of dimensions. The national standard stipulates that there are 20 levels. From IT01, IT0, IT1, IT2 to IT18, the larger the number, the lower the tolerance level (processing accuracy), the larger the allowable variation range (tolerance value) of dimensions, and the smaller the processing difficulty. For general NC machining, the tolerance for each tool is basically within plus or minus 0.3. General tolerance precision standard for sheet metal parts 1. Purpose Adopt unified and standardized unmarked tolerance standards, standardize the design, production and acceptance standards of sheet metal parts, and ensure that sheet metal Precision requirements for machined parts. (1) It can effectively simplify drawing, save design time, and exchange information efficiently. 2. The size with tolerance marked on the drawing shall be highlighted to facilitate production and manufacturing. 3. Simplifying inspection requirements is helpful to quality management. High quality and high efficiency production can be achieved. 2. Scope of application: trial run from the date of promulgation of the standard, applicable to newly designed sheet metal parts after promulgation (The previously designed sheet metal parts are also manufactured and accepted according to the original standard.) The whole stage from design drawing, production and manufacturing to product acceptance is operated according to this standard. Sheet metal processing 3 Responsibilities 3.1 Technical Center The Technical Center shall design in accordance with this standard. See Appendix - for standard reference. No special requirements for functions General tolerances are applied to elements, The tolerance may not be indicated on the drawings, but only the technical requirements or technical documents shall refer to this Standards.
