    Die castings are made for the automotive industry. Although die castings have been used in many industries, the design of modern die casting processes can meet the needs of many metal parts in automobile production. Hot chamber die castingZinc die castings used in the automotive industry involve a process called hot chamber die casting. Heat the zinc until it reaches a molten state, then press it into a mold in the shape of the desired car part. After the metal has cooled and hardened, it is removed from the mold. In this method, the furnace and mold are connected as a single machine. The pressure comes from a hydraulic piston that pushes the molten zinc out of the furnace and into the mold. Traditional aluminum die casting cannot use this process because the melting point of aluminum is much higher than that of zinc. Aluminum die casting requires cold chamber die casting, where the furnace and die casting are separated. The metal is melted in the furnace and then transported to the casting machine where it is forced into the mold. Hot chamber processing is faster because you can skip the step of transferring molten metal to the mold. This is another reason why using zinc parts can help you speed up car production. Jiaxing Yunhe Trading Co., Ltd. is a professional     Die casting supplier   in China. Specializing in the production of aluminum alloy die-casting, zinc alloy die-casting and other non-ferrous metal die-casting products.

    Before evaluating any new or replacement    Mold release agent   , the production benchmark should be determined and the number of cycles that can be achieved before the release agent is reapplied. For example, if you want to spray every sixth time on Part X, check if you can spray every seventh or eighth time. Each additional cycle without spraying can save a lot of money. When choosing an agent to eliminate cycle time reduction issues, follow some important steps below. Use the most difficult part to test. If it looks good, try it on other parts molded from multiple resins. Eliminate debris. Make sure to clean the mold thoroughly and remove all traces of old release agent. Cleaning the mold before each test helps to ensure that the test results are accurate and reflect the performance of the specific release agent. Consistently. Ensure that the molding conditions will not change during the trial period. It is best to set up and evaluate all mold release properties during one stamping operation, because each operator has his own working style and style, just like molding machines and molds. This will affect the performance and molding results of the release agent. Test to see how many parts can be released with the current mold version and settings. Then clean the mold to ensure a fresh molding environment. Apply the new test release agent according to the instructions, then run the mold until the part starts to hang and you need to apply the test release agent again. Repeat this process several times to ensure that a large number of test results are obtained for comparison to ensure consistency. Try to ensure that the only factor that changes is demoulding. The same operator, resin, mold temperature and pressure are used, so these factors will not affect the results. Use the whole can. After selecting the most effective release agent, test with a full tank and record the number of molded parts. As more demolding products are used on the mold cavity, the demolding performance may change in both positive and negative directions. Using too much release agent will cause the surface of the mold to accumulate and adversely affect the release of the part; too much release agent will cause premature adhesion of the part. Determine the cost-effectiveness of release. Calculate the cost of each part by dividing the number of parts of the mold release product A by the cost per tank. The demoulded product B is then used for this calculation. This will provide an accurate measure of the cost of each demolded part to purchase the release agent. Generally, more expensive release agent tanks can provide greater performance in the number of released parts, so that when more expensive but better performance release agents are used, the cost of each released part can be much lower. Choose according to productivity. It is important not to evaluate products based solely on product prices. A more important indicator is the number of parts that the product can release. What is really interesting is the amount of money spent on release and the maximum number of parts that can be molded. Now that the release assessment can determine the key facts, you can calculate the most appropriate release for a particular resin and part. Alkyl alkyl polysiloxane is the core raw material of die-casting water-based release agent. It provides excellent heat resistance for the release agent formulation and can maintain the function of the formulation during the die casting process. Silway provides mold release agents and finished product raw materials mold release agent manufacturers, and is also a professional supplier of    agricultural adjuvant   . The agricultural industry provides various solutions, including: silicone additives, silicone defoamers, water retention agents, methylated seed oil surfactants.

    The design of die-casting parts must take into account the wall thickness of the die-casting parts, the fillet and demolding angle of the die-casting parts, the reinforcement ribs, the minimum distance between the holes and the holes on the die-casting parts, and the rectangular holes and grooves on the die-casting parts. There are several aspects of the machining allowance of the inserts and die-casting parts. 1. Design specification for casting filletGenerally, all parts of the die casting should have rounded corners (except at the parting surface), which can make the metal flow smoothly when filling, and the gas is easier to discharge, and can avoid cracks due to acute angles. For die-casting parts that need to be electroplated and painted, the rounded corners can be evenly coated to prevent the accumulation of paint at the sharp corners. The fillet radius R of die castings is generally not less than 1mm, and the minimum fillet radius is 0.5 mm. 2. Design specifications for inserts in die castingsFirst, the number of inserts on the die-casting part should not be too much; secondly, the connection between the insert and the die-casting part must be firm, and it is required to slot, bulge, knurl, etc. on the insert; thirdly, the insert must avoid sharp corners In order to facilitate the placement and prevent the stress concentration of the casting, if there is serious electrochemical corrosion between the casting and the insert, the surface of the insert needs to be protected by plating; finally, the casting with the insert should avoid heat treatment to avoid the phase of the two metals. The change causes volume change and loosens the insert. 3. Design specifications for the wall thickness of die castingsThin-walled die castings have higher strength and better compactness than thick-walled die castings. In view of this, the design of die castings should follow this principle: the wall thickness should be reduced as much as possible on the premise of ensuring that the casting has sufficient strength and rigidity. And keep the wall thickness uniform. Practice has proved that the wall thickness design of die-casting parts is generally 2.5-4mm, and parts with a wall thickness of more than 6mm should not be produced by die-casting process. The performance of the influence of too thick and thin walls of die castings on the quality of castings: If the walls of the castings are too thin in the design, the metal will not be welded well, which directly affects the strength of the castings, and will also cause difficulties in forming; the walls are too thick or severely uneven At the same time, shrinkage and cracks are easy to occur. On the other hand, as the wall thickness increases, defects such as pores and shrinkage porosity inside the casting also increase, which will also reduce the strength of the casting and affect the quality of the casting. 4. Design specification for die casting machining allowanceUnder normal circumstances, due to the limitations of the die-casting process, when certain dimensional accuracy, surface roughness or form and position tolerances of the die-casting parts cannot meet the requirements of the product drawings, the company should first consider the use of such as correction, flattening, extrusion, Reshaping and other finishing methods are used to repair. When finishing cannot completely solve these problems, some parts of the die casting should be mechanically processed. It should be noted here that you should consider choosing more Small machining allowance, and try to use the surface that is not affected by the parting surface and active forming as the rough reference surface, so as not to affect the machining accuracy. 5. Design specification for the draft angle of die castingWhen designing die castings, there should be a structural slope in the structure. When there is no structural slope, there must be a process slope for demoulding where necessary. The direction of the slope must be consistent with the demolding direction of the casting. The main products of    Power generating tools    include various accessories for automobiles and motorcycles, motor parts, luggage, medical equipment (wheelchairs), lights, LEDs, locks, accessories, elbows, strollers, belt buckles and hardware accessories.

    Die casting is a metal casting method in which molten metal is pressed into a cavity by using very high pressure. There are many different types of die castings, which are characterized by the use of non-ferrous metals in the process. The most common are zinc, aluminum, copper, magnesium, lead or tin-based alloys. These metals have different advantages, which can be weighed according to the purpose of the casting. For example, aluminum die casting is a lightweight material that provides excellent stability for complex shapes. Zinc is also very common because it is the easiest metal to cast, with high impact strength and long mold life. There are several main steps in the die casting process. These steps start with the preparation of the mold. This step is completed by spraying lubricant into the mold cavity, which helps control the temperature and makes it easier to remove. Die casting: fillingAfter preparing the mold, the next stage is called filling, in which molten metal is injected into the mold through a high-pressure system. Fill the cavity and maintain the pressure until the casting hardens. The high-pressure nature of the injection allows the mold to be filled quickly, which is essential for the entire cavity to be filled before any part of the casting becomes solid, thereby helping to obtain a smoother texture.   After the filling enters the ejection stage of the die-casting process, the mold is opened and the injection material is ejected into the ejector pin. Since there are usually many cavities in a single mold, these injections are different from casting.   Finally, the crushing stage separates the waste from the pellets. Usually, the phase-out phase includes special dressing molds, although it may also involve sawing and grinding. Another way is to flip the lens, if the door is thin and easily breaks, you can use it.   No matter which precise method is used in the die casting process, it can provide excellent dimensional accuracy and a smooth casting surface. It also provides thinner strokes and faster productivity, while still maintaining high casting tensile strength.   Die casting can be used in many different industries to create strategic advantages and efficiency. For example, automotive castings allow you to design flexibility and maximum durability in lighter weight castings. Die castings, such as those made of aluminum, can provide the higher strength/weight ratio that manufacturers are seeking.   Jiaxing Yunhe Trading Co., Ltd. is a professional Die casting manufacturer, wholesaler and supplier of suppression in China. Specializing in the production of aluminum alloy die-casting, zinc alloy die-casting and other non-ferrous metal die-casting products. Our products mainly cover automobiles, motorcycles, auto parts, luggage, medical equipment (wheelchairs),    Lamps and lanterns   , LEDs, etc. We have technologies for smelting aluminum, zinc, copper, etc., and have passed ISO9001: 2008 quality management system certification standards.

    With the continuous development of network technology and integrated wiring technology, network communication equipment, data center servers and other IT facilities are developing towards racking, networking, and miniaturization. Therefore, the status of cabinets has evolved into a very The important role, take you to learn the basic knowledge of the cabinet today. First, the classification of the cabinet Extended classification: console, monitoring console, tool cabinet, standard cabinet, network cabinet, computer cabinet cabinet, stainless steel cabinet. According to the scope of application: power cabinets, server cabinets, indoor cabinets, communication cabinets, outdoor cabinets, industrial safety cabinets, low-voltage power distribution cabinets. Divided by function: fireproof antimagnetic cabinet, safety cabinet, waterproof cabinet, safe, multimedia console, file cabinet, wall cabinet, power cabinet, monitoring cabinet, shielding cabinet. Second, the concept of capacity "U" The height of the equipment installation in the 19-inch standard cabinet cabinet is represented by a special unit "U". U refers to the effective internal space of the cabinet, 1U=44.45mm. That is, how many U of 19-inch standard equipment can be installed, and the panel of standard equipment using 19-inch standard cabinets is generally manufactured according to the specification of n U. Third, the difference between racks and cabinets They are used to place 19-inch equipment, the load capacity of the 4-post rack is greater than the 2-post rack, the 2-post rack accessories are cantilevered, fixed at 2 points, and the 4-post rack accessories are installed in the same way as the cabinet, 4 points fixed , And the cabinet is closed, which is conducive to the protection of internal equipment; but the rack is open, there are no doors at the front, back, left, and right to facilitate the installation and construction of related equipment, but the dustproofness is relatively poor. Compared with the cabinet, the external environment requires more Higher. Fourth, the difference between network cabinets and server cabinets There are requirements on the depth, height, and load bearing of the cabinet. The width is generally 600MM, and the depth is generally more than 900MM. Due to the large heat dissipation of the internal equipment, the front and rear doors are provided with ventilation holes. The power cabinet cabinet and the server cabinet cabinet are 19 inches. Standard cabinets, server cabinets are used to install servers, monitors, UPS and other 19 "standard equipment and non-19" standard equipment. The network cabinet is mainly used to store network equipment and accessories such as routers, switches, and distribution frames. The depth is generally less than 800MM, and the width is 600 and 800MM. The front door is generally a transparent tempered glass door, which has low requirements for heat dissipation and environment. Fifth, the concept of grounding Grounding includes signal grounding and chassis grounding. The signal grounding function of the equipment is to provide the level reference plane of some or all circuits of the equipment. The ideal grounding plane is a physical entity with zero potential and zero impedance. Any current passes through it. There will be no voltage drop at all times, and the signal ground is usually realized by a dedicated grounding copper bar; The earth connection of the bushing is to realize the safety earthing of the equipment, prevent electric leakage, and realize the safety protection of the operator. OEM/ODM supports metal indoor rack server network cabinets, high-quality supply  network rack cabinet   , and home network cabinets.
