How long does it take to turn ideas into reality and drawings into real products? Generally, different industries have different production cycles. For the die casting mold industry, the processing volume is determined according to the size and structure complexity of the parts. FLOW PATH How long does it take to turn ideas into reality and drawings into real products? Generally, different industries have different production cycles. For the die casting mold industry, the processing volume is determined according to the size and structure complexity of the parts. CAMEL DIE got a set of a die-casting mold project from one of our American customers in May of 2020. This die-casting part is a metal gasket used on aircraft seats. Due to the product design updates and change in the number of cavities from 2 cavities to 4 cavities we provided the updated quotation within 24 hours with all related details such as the mold base, tool action (slider requirement), cavities, estimated casting machine size for the first trial, estimated die casting mold size(mm), estimated mold life, design confirmation timing, steel cutting to T1 (weeks), mold cost and freight cost. etc. CAMEL is committed to improving our response speed. Serving our customers and fulfilling their requirements is our standard. When our client wanted to proceed to start this project however, they needed to expedite the lead time to 5 weeks instead of the 8 weeks we had originally quoted. Had this requirement not been met, we would have stood to lose the order. After strong communication with our team of experts and the detailed evaluation of this project, we determined that it could be completed in advance within the required time. To support long-term cooperation with our customer, we proceeded with the designing in advance before we got the order. This saved us one week of lead time, and we were thus able to adjust the processing schedule accordingly. With our strong motivation to go above and beyond our customer’s expectations to build quality molds we thrive on being flexible with lead time without cutting any corners. After we confirmed the completion of the required changes with our customer the order was promptly confirmed. Upon receiving the order confirmation, we immediately began to prepare for the die casting mold design and submitted the product analysis report in one working day. In the DFM report, all details were confirmed with our client, such as the parting line, injection pin, visible areas, inserts, split lines, ejection location, engraving & cavity, radii, machining & allowance, complete information of the die-casting machine, clamping slot, etc., as well as some suggestions about the parts. The mold flow analysis report was provided within 3 working days and the 3D mold drawing in 2 working days. Our teamwork cooperation and communication were smooth and efficient and because of that the design confirmation was completed in one week. During the mold building process, we strictly followed our project management system in order to ensure quality control. If there were any pending questions that required confirmation with our clients our team ensured that a prompt reply was provided with our suggestive solutions so that everything remained on schedule. Because of our teams’ strong work ethic and attention to detail the entire project went very smoothly and in fact we were able to finish the project one week in advance which our client was incredibly pleased with. During the mold building process, we made sure to keep our client up to date on every step and detail to ensure we were all on the same page. An example of this is that we submitted the tooling schedule and weekly report status with pictures of the mold process. After we finished the mold build and completed the T1 trial, we provided our client with the trial report with detailed photos of the mold and parts. We also provided the die casting machine parameter data. The FAI report was provided in 3 working days to ensure all measurements were in the correct tolerance . After inspection by our engineers, we confirmed that there were no issues with the samples and sent 5-10pcs to our customer for assembly inspection. The whole project went exceptionally smooth. As normal it took 7 days by express freight for our client to receive the samples. After inspection and measurement confirmation our client provided feedback to CAMEL If there were any updated suggestions. With detailed review and confirmation our client approved these samples after 2 weeks then informed us to arrange the mold shipment. We promptly proceeded with inspecting all mold components, assembling the mold, and running one more trial before shipment.

This page Introduces steps 4-5 of die casting mold design on this page. Steps Of Die Casting Die(HPDC Mold) Design II Die casting mold design, We often said as design of die casting dies or die casting die design. Also, Which be called die casting mould design in some countries. The basic die casting die design steps are summarized as follows: 1. Understand and determine the task 2. Design preparation 3. Select the parting surface and die casting system 4. Choose the die casting equipment 5. Determine the appropriate mold structure and draw the mold assembly sketch * 6. Calculation and verification of relevant parameters * 7. Draw the die casting mold pattern * 8. Proofreading and review * 9. Organize and archive design materials Next, Introduces steps 4-5 of die casting mold design on this page. STEPS OF DIE CASTING DIE(HPDC MOLD) DESIGN II 4. Choose the die casting equipment 4 Dies design is carried out according to the type of die casting equipment, so it is necessary to be familiar with the performance, specifications, and characteristics of various die-casting equipment. For die casting machines, the following should be understood in terms of specifications: clamping force, pressure chamber capacity, injection pressure, mold opening stroke, mold opening force and ejection force, mold installation dimensions, ejection device and its size, die casting machine Gate displacement distance, gate sleeve positioning ring size, mold maximum, and minimum thickness, installation matching size, etc. According to the quality of the die casting and the total projected area of the die casting on the parting surface, the required clamping force is calculated, and the overall dimensions of the die are preliminarily estimated. Combined with the actual die casting machine situation of the die casting production unit, the die casting machine is initially selected. 5. Determine the appropriate mold structure and draw the mold assembly sketch * 5 The main content of this part includes (1) The form of the gating system and the overflow system, including the sprue, the runner, and the position, shape, and size of the inner gate, as well as the exhaust overflow method, etc. (2) The structure of the formed part (3) The demolding method of die castings, the method and sequence of mold opening, the selection and design of the ejection mechanism, etc. (4) The structure of the main parts and the ruler and the required installation cooperation relationship (5) Selection of mold base, combination design of supporting and connecting parts (6) Cooling and heating method and mold temperature adjustment system When determining the structure of the die-casting mold, the following conditions should be considered (1) Each structural element in the mold should have sufficient rigidity to withstand the clamping force and the back pressure during liquid metal filling without deformation. All parts in contact with molten metal should be heat-resistant die steel. (2) Try to prevent the molten metal from impacting or scouring the core from the front to avoid erosion at the inflow of the inner gate. When the above situation is unavoidable, the eroded part should be made into a block type so that it can be replaced frequently. It is also possible to use a larger internal gate section and maintain the thermal balance of the mold to improve the life of the mold. (3) Reasonably choose the combination of mold inserts to avoid sharp corners and sharp splits to meet the requirements of heat treatment. The push rod and core hole should keep a certain distance from the edge of the insert to avoid weakening the strength of the insert. The fragile parts of the mold should also consider the inlay structure for easy replacement. (4) After splicing at the forming part, it is easy to leave splicing marks on the die casting. The location of splicing marks should consider the aesthetics and performance of the die casting. (5) The size of the mold should correspond to the selected die-casting machine. Drawing a sketch of the mold structure can check the coordination relationship between the considered structures. For inexperienced designers, this sketch is used to solicit the opinions of mold manufacturing and mold operators so as to introduce their rich practical experience into the design. 6. Calculation and verification of relevant parameters * 6 (1) Calculate the working size of the formed part; (2) Calculate and verify the thickness of the side wall and bottom plate of the formed part cavity to determine the size of the template; (3) Calculate core-pulling force, core-pulling distance, mold-opening stroke required for core-pulling, and size of related core-pulling parts such as diagonal pins; (4) Check of push rod compression instability; (5) Calculate the temperature adjustment system parameters; (6) Checking the relevant parameters of the die casting machine Link to: STEPS OF DIE CASTING DIE(HPDC MOLD) DESIGN I Link to: STEPS OF DIE CASTING DIE(HPDC MOLD) DESIGN III contact

Failure Mode and Analysis of Aluminum Alloy Die-casting Dies. Aluminum alloy die-casting dies as bearing high temperature, high pressure, and high-speed aluminum liquid carrier, its working environment is extremely harsh. Failure Mode And Analysis Of Die-casting Dies For Aluminum Alloy The vigorous development of the automobile industry and the need for lightweight, so that Aluminum alloy Die-casting is to the large-scale and complex direction of rapid development. Die-casting dies as the main equipment of Die-casting production is to achieve the basic guarantee of high quality and efficient production of Die-casting, its life directly affects the quality of Die-castings, production, as well as the production cost of enterprises and market competitiveness. At present, in most countries, the low service life of the Aluminum alloy Die-casting dies problem becomes the main factor that restricts the further development of die-casting industry, the failure mode of Aluminum alloy die-casting dies is more problematic. 1. Working environment of Aluminum alloy Die-casting dies Aluminum alloy Die-casting dies as a carrier of high temperature, high pressure, high speed Aluminum liquid, its working environment is extremely harsh. When working, the cavity surface is repeatedly flushed by the Aluminum liquid, the specific pressure is more than 40MPa, the inner sprue speed is 30~65m/s, the mold cavity surface temperature can reach 1112°F or more instantly, and after opening the mold, the mold cavity surface temperature drops sharply due to spraying and other reasons. This kind of hot and cold alternating effect in the die-casting cycle repeatedly, making the mold cavity surface temperature changes dramatically. 2. Failure mode and analysis of Die-casting dies According to the field statistics, the common failure forms of Die-casting dies are cracked, cracking, erosion, adhesion, and deformation, etc. Among them, cracked, cracking, erosion, and adhesion mainly occur in the mold cavity surface. (1) Cracked: In each Die-casting cycle, due to the existence of intense heat exchange, the mold temperature changes dramatically, the resulting thermal stress leads to thermal fatigue on the surface of the mold cavity, forming micro cracks. With the increase of Die-casting cycle, the micro-cracks further expand and form crack. This is the main mode of Die-casting dies failure field. (2) Cracking: In the Die-casting production, in addition to thermal stress, due to the high-pressure impact of Aluminum, in the mold internal also produced other stresses. When these stresses exceed the fatigue limit of the mold material will produce cracking, especially easy to produce stress concentration of the sharp corner parts, the possibility of cracking is greater. In addition, if the stress generated during the processing of the mold is not completely eliminated, the mold is more likely to crack. (3) Erosion: Aluminum high speed filling cavity friction heat, so that the surface temperature of the area on the surface of the mold cavity towards the inner sprue, coupled with the violent impact of Aluminum, so the surface protection layer of this part is easy to be destroyed. The Aluminum solution further reacts with the exposed metal substrate to produce harder compounds. In the process of removing these compounds, it is easy to take away the substrate material and expose the fresh surface, and so on, intensifying the damage of the cavity surface, forming a serious erosion. (4) Adhesion: Pressure injection, the instantaneous temperature of the cavity surface at 1112°F. above, at this time, the affinity between the mold material and Aluminum liquid, strong adhesion, easy to form cavity adhesion. (5) Deformation: In the Die-casting process, Die-casting dies to withstand the clamping force, injection backpressure, and other stresses, if the template stiffness is not enough, the mold in these stresses under the long-term role of bending deformation. (6) Movement Obstacle: In Die-casting production, the temperature difference between inside and outside the mold, resulting in different thermal deformation of each part of the mold. Different heat deformation amount leads to different changes in the size of each part of the mold, thus changing the fit relationship between the mold parts. This change of fit relationship may cause significant movement obstruction of the mold parts with relative movement. LINKS： 1. How to Extend The Service Life Of Die-casting Tools 2.

Die-casting die life and material, design, manufacturing, and maintenance have a close relationship. In the actual application, we found that the influence of die-casting die life of each Factors accounted for the proportion of roughly as follows: mold design and manufacture How to extend the life of die casting dies The service life of die-casting dies is closely related to the material, design, manufacture, and maintenance. In the actual application, we found, affect the die-casting dies life of the proportion of each element is rough as follows: mold design and manufacturing about 80%; including mold materials about 10% ~ 15%; mold use and maintenance and maintenance of about 5% ~ 10%. Take the following measures is to avoid die-casting mold failure, improve its life effective method. 1. Mold material 2. Mold design 3. Mold manufacturing 4. Heat treatment of the mold 5. Use and maintenance of the mold 1. Mold material 1 Die cavity material should be selected with the excellent overall performance of the hot work mold steel. Try to use finer grain, isotropic good, good heat treatment performance of the material as the mold cavity material. At present, the domestic common use SK61, DACS5, 8407, and other imported materials as mold cavity materials. Before the mold material is put into processing, the appearance inspection, metallographic inspection, and ultrasonic flaw inspection should be used to check the material to avoid using defective material, which will cause early scrap of the mold. 2. Mold design 2 (1) Pouring system design The pouring system design is the core part of die casting mold design, especially the position and size of the inner sprue. When choosing the location of the inner sprue, try to avoid the frontal impact of the aluminum liquid on the core, in order to reduce the generation of erosion. In the case of ensuring that the casting is well-formed, increase the cross-sectional area of the inner sprue, so that the aluminum liquid enters the cavity in the form of laminar flow, thus reducing the speed of the inner sprue and reducing the impact of the aluminum liquid on the cavity. (2)Forming parts design As far as possible to avoid sharp corners, in order to prevent the corresponding parts of the mold due to stress concentration and cracking. The unavoidable vulnerable parts, such as the slender core, should be used in a reasonable patchwork structure, so as to facilitate timely replacement when damaged. (3)Formwork design Determine the appropriate thickness of the template, so that it has sufficient rigidity and strength to effectively resist bending deformation. In the template, especially the structure design of the moving mold template, the integral template instead of the traditional support plate and through the template, is conducive to improving the overall bearing capacity of the die casting mold. (4)Design of guiding parts First of all, each guide part should choose the correct tolerance fit and surface roughness level. Second, improve the structure of the guiding parts, such as with the slider with the side and bottom surface into easy to replace the guide slip, while the guide slip chooses to wear resistance and thermal expansion of better alloy materials. (5) Easy to replace the design of maintenance For the easily damaged core and sliding fit parts, design the structure to facilitate rapid replacement and maintenance. Such as the core from the step-type fixed structure to the screw-type connection structure. (6) Maintain the thermal balance of the mold Reasonable design of cooling system to ensure the overall thermal balance of the mold. If conditions permit, you can choose to configure the mold temperature balancing system. (7)Apply CAD/ CAE technology CAE simulation analysis is carried out to determine the distribution of temperature field, flow field, and stress field of the mold after the preliminary design has been completed. And on this basis, the mold design optimization, in order to improve the overall quality of mold design, so as to improve the die casting mold life to provide a strong guarantee. 3. Mold manufacturing 3 (1)Develop reasonable processing technology The machining process of the mold is the link that directly affects the life of the mold and needs to pay attention to the details of the process. For example: choose the appropriate processing benchmark, it is best to unify the parts of the processing benchmark, in order to reduce the cumulative error; two-sided butt method of processing longer cooling water hole, in order to ensure the smooth surface of the water hole at the same time, should also pay attention to ensure its coaxial, to avoid stress concentration and cracking; comprehensive use of CAD / CAM technology, improve the accuracy of processing, etc. (2)Electric discharge machining EDM is widely used in mold manufacturing. After EDM, a hardened layer appears on the surface of the cavity. The thickness of the hardened layer is determined by the current intensity and frequency of machining, which is deeper for rough machining and shallower for finishing.2 No matter how deep or shallow the hardened layer is, it will produce large stress on the surface of the mold. Therefore, the hardened layer should be eliminated or stress relieved by high-frequency EDM and other technological measures. (3) Grinding The large amount of frictional heat generated by grinding may soften the surface of the mold and reduce its ability to resist thermal fatigue, thus causing early failure of the mold. Therefore, when grinding, the amount of coolant should be moderate, and avoid excessive grinding volume and feed to avoid fine cracks in grinding. (4)Weld repair Welding is a common means of repairing mold processing errors. When welding, the surface is thoroughly cleaned and dried, the mold is preheated to 440~460℃ together with the welding rod, and after the surface of the mold is at the same temperature as the heart, the welding is carried out under protective gas. After the repair is completed, temper once at a temperature 50~80 below the original tempering temperature to eliminate stress. (5)Polishing Focus on polishing the narrow seams and deep grooves in the cavity to ensure that the overall roughness of the cavity reaches 0.2um, so as to reduce the flow resistance of the cavity surface and improve its resistance to galling and fatigue. 4. Heat treatment of the mold 4 (1)Quenching and tempering Vacuum quenching can effectively prevent the cavity surface decarburization and carbonization, reduce the early cracking of the mold caused by inadequate dissolution of carbide during heat treatment. After vacuum quenching, 2~4 times tempering is required. In general, the larger the mold, the higher the quenching temperature, and the lower the tempering temperature. (2)Stress relief tempering The new mold in the mold after passing the test should be tempered to eliminate stress. (3)Nitriding Nitriding treatment of cavity surface can improve the ability of mold surface to resist wear, adhesion, and thermal fatigue. After the new mold is qualified, the first nitriding is carried out. In the process of use, the timing of nitriding is determined according to the specific maintenance procedures and the condition of the mold. When nitriding, the hardness of the nitriding substrate should be between 35~43HRC, and the thickness of the nitriding layer should not exceed 0.15mm, and attention should be paid to the cleanliness of the nitriding surface to ensure the uniformity of the nitriding layer. When the cracking of the mold is serious, nitriding is not suitable. 5. Use and maintenance of the mold 5 (1)Reasonable setting of die-casting process parameters Under the premise of ensuring the quality of the castings, try to reduce the pouring temperature of the aluminum liquid, injection speed and injection pressure, shorten the high temperature holding time, especially to eliminate the practice of relying solely on increasing the injection pressure to improve the quality of the castings. In addition, you can use the parameter tester to seek the best combination between the parameters. (2) Evenly preheat the mold Avoid using the gas heating method to preheat the mold to prevent different thermal expansion of each part due to uneven preheating. It is better to preheat the mold with the oil temperature of the mold temperature machine. In the case of no mold temperature machine, can use the method of several molds before test pressing, rely on aluminum liquid preheat mold cavity. (3)Spraying evenly Focus on spraying the deep cavity of the mold, and at the same time, pay attention to avoid long-time spraying. (4)Keep the heat balance of the mold Regularly check and clean the cooling system to prevent the cooling water channel from being blocked, so as to ensure a stable mold temperature. (5)Timely mold inspection Pay attention to check whether there are cracks, crazing, and erosion on the mold surface. If these conditions appear, it is necessary to use the method of welding repair in time. If the nitriding layer on the surface of the mold cavity is partially damaged, the nitriding treatment should be carried out again. (6) Periodic stress relief tempering This is an effective method to retard cracking. According to the size and complexity of the mold to determine the time interval of stress-relieving tempering. In general, the aluminum alloy die casting mold in the first batch production 5000 ~ 8000 times, after every 10000 ~ 15000 times for stress relief treatment. However, if the mold cracking is serious, it is not suitable to carry out stress relief tempering, so as not to intensify the expansion of cracks. (7)The mold maintenance when stopping During the production, when stopping temporarily, you can reduce the cooling water flow and let the mold cool slowly. If it is stopped for a long time, the mold must be thoroughly cleaned and maintained and put into storage after passing the inspection. (8) Operation training Pay full attention to the operator's work training, to eliminate the mold damage caused by improper operation. Conclusion: Improving the life of aluminum alloy die-casting mold is a comprehensive technical issue. In the actual application, comprehensive consideration of the role of the influencing factors, and take targeted measures, it is possible to improve the service life of aluminum alloy die-casting dies. contact
