        To make steelChina Mechanical Parts a thorough understanding of steel grades, production options (such as die casting and CNC), and material analysis options to ensure you get paid. This coversWhen to use CNC machiningWhen to use die castingCNC and die casting cost calculationChinese steel grades (and their international equivalents)Import of steel from other countries (for Chinese manufacturing projects)Materials AnalysisOn-site inspection of steel parts Suppose I want to make some kind of steel. How do I know that die casting or CNC is the best way?This actually depends on many factors, such as the complexity of the component, surface finish requirements, yield, part size, and material selection. Casting is the process of injecting molten metal into a mold. When the metal solidifies, it takes the shape of a mold, such as a crankcase (in a car engine). There is almost no waste during the production of the part, and the gate can be used for other parts after the gate is remelted. CNC machining, on the other hand, requires a solid blank and machining from unwanted metals until the geometry of the final part is left. This process generates a large amount of scrap that can no longer be used for the production and is usually sold at scrap metal prices. Yield is a big determining factor. For small batch production, CNC processing is more meaningful as it does not involve mold costs. A significant portion of the cost of high-pressure die-casting molds can be a significant capital investment. However, if output is high, the unit cost will ultimately be much less.

    China's machining of mechanical parts is a type of machining, but it is precision machining. With the development of the industry and continuous changes in demand, compact machining has changed a lot. Its classification is more and more, and its direction is more and more. The finer the direction, the more professional the direction. With the development of technology, the manufacturing technology of Automobile Press Parts has been continuously improved, and the quality and accuracy of processing have become higher and higher. Technological and economic development feels a tight mechanical development direction. Due to the emergence of machinery, China also has corresponding mechanical parts. But as a discipline, Chinese mechanical parts are separate from mechanical construction and mechanics. With the development of the machinery industry, new design theories and methods, new materials and new processes have emerged, and automotive stamping parts have entered a new stage of development. Finite element methods, fracture mechanics, dynamic fluid dynamic lubrication, optimization design, reliability design, computer-aided design (CAD), solid modeling (Pro, Ug, Solidworks, etc.), the theory of system analysis and design methodology has gradually been used for research Design of mechanical parts in China. Better integration of multiple disciplines, the combination of macro and micro, exploration of new principles and structures, the use of more dynamic design and precise design, more effective use of electronic computers, and further development of design theories and methods. An important trend in subject development. Therefore, in the future, precision machinery will become increasingly integrated. It is no longer purely mechanical. Its combination with high technology played a role. Especially the digitization of processing has made its development a qualitative leap. It will become an important science in the future and serve industrial development.

    Before actually redesigning an China Mechanical Parts , establish basic project management routines to determine the scope and parameters of the project. This routine considers the project's purpose, market, design goals, constraints and functional details. Design teams involved in the redesign project studied the product's functions and the interactions between the components, sub-assemblies, and main assemblies through disassembly. The functional study of the product also shows how the original manufacturer produced the product and resulted in a detailed analysis of the structural, mechanical and electrical subsystems. The analysis should include measurements, coverage of the control system, consideration of safety measures, and an overview of the overall system design. Any product test should disclose the performance of the product in different environments, durability issues, and how the original manufacturer views ergonomics. Functional research and analysis of products intended for reverse engineering should provide documentation that identifies design goals, provides measurement systems, and lists possible constraints. Design goals should cover form, function and materials. The design team reviewing mechanical parts for reverse engineering shall provide materials, parts, component lists and all upgrade results. The reverse engineering process is the opposite of a typical design process, with product design specifications as the end point of the process. Reverse engineering relies on using a laser scanner or a computed tomography (CT) scanner to capture the data. The scanner outputs the 3D scan data as a dense triangular point cloud, which becomes a visual sketch containing detailed dimensions of the part. Capturing detailed information during reverse engineering laid the foundation for testing. Deviation analysis of reverse engineering machinery parts allows precise point-by-point comparisons of original and new designs. This analysis can detect any deviation between the scanned data of a part, assembly or mechanical part and the CAD model. As a result, the design team can verify that the reverse engineering product will meet or exceed performance targets while validating the tool.

      Stamping Parts is the process of turning a flat metal plate into a shape using a mold. In the most basic sense, this is the process of cutting metal with parts. Stamping can be performed either stepwise or with stage tools. Metal stamping is used to produce large mechanical parts and can also be shaped into the shape of household items. Metal stamping is commonly used in the manufacture of parts in almost all industrial fields. Some of them include:agricultureHome appliancesAutomobile industryconstructionelectronic productMedicalPlumbingRecreational vehicleSmall engineAlthough metal stamping is widely used, it is difficult for individuals to maintain different types of stamping straight. Stamped components are mainly made by applying only a few different types of forces. Here are three examples of metal stamping: Punch pressPunches are used to cut holes in the material. It's easy to remember if you think about how they "punch holes" in sheet metal. Punch presses range from smaller, manually operated machines to very large CNC-operated machines that can accommodate larger, more complex molds. Punches can be used for blanks or perforations.2. Tower PressA turret punch, also called a turret punch, is a press that uses a large number of standard punch tools. Turret type presses can manufacture various parts without special tools. The versatility of turret presses enables manufacturers to perform rapid prototyping and small batch production without waiting for the hassle of designing and manufacturing molds.3.Brake press3 types of metal stamping: stamping press, turret press and brake press. Although punches are used to cut holes in materials, brake presses are used to bend materials. The brake press presses the clamp on a piece of metal plate and applies pressure until it reaches the required degree of bending. There are several types of brake presses, including mechanical presses, hydraulic presses, and pneumatic presses. In order to bend the material, each applies a different pressure.

Defects In Metal Stampings

As one of the common metal stamping defects, there are various reasons for chipping, some of which are due to poor mold design, some are due to poor material, and some are stamping operators. The first reason is that the punch or other parts of the metal stamping die are abnormally scraped or damaged, causing micro waste, which is mainly due to the excessive effect of the material when the punch does not have a homogeneous structure.

The first reason is that metal stampings of punches or other parts are abnormally scratched or damaged, resulting in finishing. The point is that for homogeneous structures, the punch must have too much material.

The second reason is that the gap between metal stampings of metal materials is too large, and the design of the gap of the cutter head is not reasonable (reasonable gaps account for 4% to 6% of the material wall thickness). In the normal high-speed operation of the metal material metal stamping, in view of the frictional working frequency of the sheet and the cutting head, the internal wear state of the cutting head causes the cutting head to be too large.
The third reason is that the raw material was subjected to metal surface treatment before the stamping of the mold, and there was a non-structured fusion state in the metal surface treatment layer, which caused the material edges to peel and fall.
Another reason is that the punches of stampings made of metallic materials are magnetically attractive, which can cause the board to bounce due to the attraction force.
