    Die casting is a metal casting process, which is characterized by applying high pressure to the molten metal using the cavity of the mold. Molds are usually made of higher-strength alloys. This process is somewhat similar to injection molding. Most die castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin and lead-tin alloys and their alloys. Depending on the type of die casting, a cold chamber die casting machine or a hot chamber die casting machine is required. The cost of casting equipment and molds is high, so the die-casting process is generally only used for mass production of a large number of products. Manufacturing die-cast parts is relatively easy, which generally only requires four main steps, and the individual cost increment is very low. Die casting is particularly suitable for manufacturing a large number of small and medium-sized castings, so die casting is the most widely used one among various casting processes. Compared with other casting techniques, the die-casting surface is flatter and has a higher dimensional consistency. Based on the traditional die-casting process, several improved processes were born, including a non-porous die-casting process that reduces casting defects and eliminates pores. It is mainly used for processing zinc, which can reduce waste and increase yield by direct injection process. Jiaxing Yunhe Trading Co., Ltd. is a professional Hardware fitting manufacturer .

    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.

    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.

    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.
