Quality CNC Machined Parts

For stamping products, the production process, mold design and selection, procurement of various materials, surface treatment and other processes are all very important. Whether it is production, design or material selection, Dongguan Fortuna has a first-class level . Next We will discuss stamping parts that you don’t know about .About precision stamping parts processing1. We attach great importance to early development work. For every new product launch, we will set up a project team to carry out special follow-up. For the development and manufacturing of metal stamping parts, we have gatheredthe company's experienced engineers in mold design and manufacturing, process engineering, etc. to produce detailed and rigorous product DFM reports.2. In terms of mold design, we have accumulated rich design and manufacturing experience. We use 3D design software to develop and design molds. We have a strong knowledge base, have brought together many cutting-edge mold structures, and have the basic strength to develop various complex precision stamping parts. We use Mitsubishi slow wire cutting, Makino EDM and other equipment to process mold parts, and use German Zeiss CMM, high-precision Rockwell hardness tester and other equipment to conduct quality inspection of mold parts to ensure that the accuracy of the mold meets manufacturing requirements.3. After the customer confirms that the sample is qualified, we will proceed to mass production. We use imported high-speed punching machines for stamping production, which can reach 800-1200/min. The production efficiency is greatly improved, which can fully meet the urgent production needs of customers.Stamping mold design steps1.First look for raw materials for mold design.The stamping ability of the product , check the formulation of the process and whether the sketches of each process are reasonable. If the stamping process is found to be poor or theformulated process is unreasonable, modifications need to be made. Only in this way can product design, process preparation, mold design and mold manufacturing be better combined;3. Carry out relevant process calculations for each process according to the work content specified in the stamping process card;4. Draw assembly drawings of stamping molds and other mold parts;5. Check the mold drawings. After the mold drawing design is completed, it needs to be inspected. This is an important step in stamping design.6. Write a stamping design calculation manual, which is an important technical document, especially some important parts of the process formula and mold design; after the design work is completed, a design calculation manual should also be compiled for future reference;Selection of processing materials1.Hardness of materialThe material selection of stamping parts is first based on the material required by the customer, and then the most suitable part of this type of material is selected, because for stamping parts processing , material selection is a very important step and is also a very critical measurement element. In terms of hardness measurement, we can use a Barcol hardness tester or a Rockwell hardness tester to test materials.2. Molding properties of materialsWhen selecting stamping materials, you need to carefully understand the molding properties of the materials, which has a very important impact on the quality of stamping products. When selecting, you can test the bending performance of the material and select molding materials with good performance.Surface treatment of metal stamping parts1.Product electroplating electroplating is a process that uses electrolysis to deposit metal or alloy on the surface of a workpiece to form a uniform, dense, and well-bonded metal layer . Through surface coating electroplating, the surface properties or dimensions of the raw materials are changed. Its main purpose is to prevent the product from wearing out during use , enhance the corrosion resistance of the original product metal (coated metals are mostly corrosion-resistant metals), make the product stronger , and also enhance the product's conductivity and heat resistance . It can improve the surface aesthetics of the product.2. Common electroplating layers(1)Copper plating: used for primer, mainly to promote the coating ability and corrosion resistance of the electroplated layer in the future. (Because copper is easily oxidized and no longer conducts electricity after oxidation, copper products must be protected with copper)(2)Nickel plating: used for foundation or appearance to improve corrosion resistance and wear resistance (the wear resistance of electroless nickel plating exceeds that of chromium plating in modern processes). (Note that many electronic products, such as DIN connectors, N connectors, etc., no longer use nickel as the base. This is mainly due to the deviation of nickel, which will affect the electrical performance of passive inter-modulation)(3)Gold plating: Improve conductive contact resistance for signal transmission. (While gold is stable, it is expensive.)(4)Tin plating: Bright tin and matte tin plating are currently mainly used to improve future welding capabilities and are widely used.(5)Silver plating: Silver has very good properties. Although it is easily oxidized, it can also conduct electricity after oxidation. Silver plating can improve conductive contact and enhance signal transmission.3. cleaning the surface materialsCleaning is a technology that uses mechanical, physical, chemical or electronic chemical methods to remove grease and other dirt attached to the surface of equipment and its parts. Cleaning is widely used in the maintenance of equipment parts, including metal parts, electronic and electrical equipment, etc. In addition, cleaning can also provide a clean surface for subsequent surface engineering treatment of equipment parts.Machine operation precautions1. Before operation, the operator should check whether all moving parts of the machine have been filled with lubricating oil, start up and check whether the clutch and brake of the machine are operating normally.2. Operators should always be vigilant when working and pay attention to safety accidents that may occur during operation. They must maintain a good mental state and must not be distracted. They must not operate in a state of irritability or fatigue to avoid accidents. When the machine is running, no part of the body can touch the working area, let alone touch it directly with hands. At the same time, other staff are not allowed to enter the machine operating area without reason, and are not allowed to change switches at will or touch the moving parts of the machine.3. For daily mold replacement, you must first turn off the power of the machine and wait for the machine to completely stop operating before proceeding with subsequent operations and starting mold debugging. After the mold is installed, check whether the mold position is symmetrical and cannot shift. Keep the screws fixed and in a reasonable position. Mold installation and disassembly must be performed in a standardized manner and standard operating tools must be used.4. When the operator leaves work, he must turn off the power and clean up the remaining debris and waste to ensure that the machine does not malfunction and the working environment is orderly.After listening to the above introduction, do you have a deeper understanding of metal stamping?

When you look at a sleek and polished car on the road, have you ever wondered how its built with such precision and accuracy? One of the fundamental processes that plays a vital role in manufacturing automobiles is "Stamping."In this comprehensive guide, we will dive in to stamping in car manufacturing, exploring the process, the crucial automotive stamping parts involved, and the different types of stamping methods used.So, let's get started.What is Stamping in Car Manufacturing?Stamping is a critical manufacturing process deeply rooted in the automotive industry. This important procedure involves forming, configuring and carefully shaping flat sheets of metal into accurate shapes and dimensions.Its importance cannot be overemphasized considering how crucial this step is in making a variety of parts that eventually find their purpose within the complex anatomy of vehicles.These accurately formed stamped parts serve two purposes during car manufacturing. Firstly, they are the foundation upon which safety in automobiles is based. These parts include the skeleton as well as the body panels to create protection around occupants of the vehicle - absorbing and distributing force exerted by impacts sustained during collisions so that occupants have some form of numbing effects instead of being thrown out from the vehicle.They also provide support for creating its core structure, helping to keep the entire vehicle stable while maintaining its strength.Secondly, the stamped components are integral not only to the aesthetic but also to the functional aspects of automobiles. They determine the sleek contours of car bodies, precise lines of hoods and fenders, and even subtle curves of interior components.Beyond aesthetics, they play a critical role in ensuring the functionality of systems such as doors, windows, and engine enclosures. In essence, stamped parts serve as canvasses upon which the visual appeal and mechanical prowess of automobiles are etched.In short, stamping in car manufacturing represents a multifaceted process that goes way beyond mere metal shaping. It is the foundation stone of automotive construction, weaving together threads of structural robustness, visual elegance and functional efficiency to produce vehicles that drive us on our roads.But what's the process? Let's discuss this at length. What's the Process?The stamping process is a complex and exact operation that encompasses several intricate steps. Here is an in-depth breakdown of the process:Material Selection: The process starts with the determination of the right type and thickness, which is generally steel or aluminum, based on real requirements of car design as well as the required properties for parts.2.Coil Feeding: Normally, sheet metal materials come in big coils. Those coils are fed into a stamping press, an industrial machine built to shape the metal.3.Crimping gauge Design: A die is a specialized tool that shapes up formed sheet metal into its desired form. However, dies are customized in design for the intended aim; that is to say, they are customized for every component to be stamped. Two major types of dice used in stamping are the male portion (punch) and female portion (die).4.Stamping Process: The punch and die are co-joined in the stamping press to deform sheet metal into the desired shape, depending on the complexity of the part. Many stamping operations will ordinarily be required that include bending, stretching, cutting, and deep drawing that should be carefully controlled to attain acceptable tolerances and quality.5.Blank-Stamp or Trimming: During the stamping process, excess material is often removed from the edges of a stamped part. This helps create clean, precise sharpness on the system component's final product, which is known as the blank-trim process.6.Quality Control: Throughout the stamping process, quality control measures are taken to make sure stamped parts to meet specifications, such as visual inspection and measurement or other quality checks.7.Assembly: After producing stamped components, they are usually assembled into larger sub-assembles or integrated with the car's chassis and body.So, that's how stamping in car manufacturing works. Now, let's discuss some automotive stamping parts.Automotive Stamping PartsAs we have said earlier, stamped parts are like puzzle pieces in a car. They fit together to make the car solid and valuable. Here are some of the essential car parts made through stamping:1. Body Parts: Stamping helps in the manufacture of the parts on the outside – doors, fenders, hood, roof especially where these create shape for those inside to be protected from wind and rain.2.Chassis Parts: The chassis is like the skeleton of the car. Stamping parts are used in building it so as to make it solid and safe.3.Inside Stuff: Inside stuff made through stamping includes seat frames, which go into building up seats, dash board, and center console—all things that make the interior of your car comfortable and user friendly for people who use cars.4.Engine and Transmission Parts: Some very important car parts—like engine and transmission components which make your car go—are shaped via stamping too.So, different metal stamping parts are being made in car manufacturing. That is why there are different types of stamping techniques that you must know in order to understand the whole procedure.Types of Stamping In Car ManufacturingVarious stamping methods are employed in car manufacturing, each tailored to specific requirements. The most prevalent types include:Mechanical Presses: Utilizes mechanical force to deform metal; ideally suited to mass production where rapid, accurate shaping of metal is essential; known for speed and precision.2.Hydraulic Presses: The hydraulic presses compress metal under the application of hydraulic fluid. They are used where exceptionally high pressure is required in deep drawing applications such as forming complex shapes.3.Mechanical Servo Presses: A mechanical servo press combines the strength of a mechanical press with the accuracy found in a hydraulic press. It offers significant flexibility and versatility so that the requirements of stamping parts can be easily adjusted to suit complicated and challenging automotive components at will.Final ThoughtsStamping plays a big role in manufacturing cars; it's not just all about making parts look pretty, but ensuring they work well and keep us safe.Stamped parts are everywhere on cars, from outside panels to inside gadgets to even the engine.With 30 years of experience as precision metal stamping and lathed parts manufacturers, we're your trusted source for metal stamping parts.Contact us today with your requirements so you can benefit from our experience in supplying high-quality components for automotive requirements.

Metal stamping parts are metal parts with a certain shape, size and performance formed by stamping process, which are widely used and have a broad market demand. What are the main characteristics of metal stamping parts, do you know?1. stamping can be processed thin wall, light weight, complex shape, good surface quality, good rigidity parts. 2. Save materials Waste can be minimized or no waste can be generated, and even in some cases the bottom and corner can be fully utilized to make other forms of parts to avoid waste. 3. the product has good interchangeability The dimensional tolerance of metal stamping parts is guaranteed by the mold, which has the same characteristics and generally does not require further processing, so the processing dimensional accuracy of the same product is high, the consistency is good, and the interchangeability is good. 4. high production efficiency With ordinary press for metal stamping processing, up to dozens of pieces per minute; Produced by high-speed press, it can reach hundreds or thousands of pieces per minute, which is suitable for large-scale production. 5. simple operation, easy to organize production, easy to realize mechanization and automation. 6. high metal stamping production efficiency, high material utilization rate, low production cost.

The connector terminal plays the role of a bridge, which is formed by stamping the die, and is used to achieve an accessory stamping product of electrical connection, which is widely used. It is mainly divided into three main parts: the plug area, the transition area and the press area.The connector area is the part where a terminal is connected to the other half. This part is designed by the connector designer to engage the docking terminal and work in a certain way. If the contact is deformed during pressing, the performance of the connector will be reduced. The transition zone is also designed to be unaffected during the pressing process. If the position of the elastic plate or terminal stop is changed, the performance of the connector will also be affected. Only the pressing area is the part of the design affected by the pressing process. Clamp the press area to securely connect to the cable using the connector manufacturer's recommended termination device. The material selection of connector terminals should take into account elasticity (tensile strength, hardness), fatigue resistance, electrical conductivity, coefficient of thermal expansion, melting point (softening characteristics), corrosion resistance, processability, wear resistance.
