    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.

    One of the main advantages of die casting is the ability to produce parts and products of various shapes and sizes. Unlike other manufacturing processes (such as extrusion), the die casting process does not limit the shape of the part, and in most cases will be the final shape of the part. Durability:Unlike plastic parts, die-cast parts are stronger than plastic parts. In most cases, this can make the wall of the part thinner while maintaining the strength required for its application. In addition, die castings can withstand a wider temperature range, making them more ideal in harsh temperatures and working environments. High-speed mass production:Because the die-casting process allows manufacturers to produce complex parts into their final shapes, little or no machining process is required, which reduces production time and makes die-casting one of the most effective processes for mass production of complex non-ferrous parts. Green manufacturing:How long does it take for biodegradation of plastics? According to scientists, it takes at least hundreds of years for plastics to degrade completely. This means that outdated plastic products will accumulate in landfills, pollute our beaches, kill millions of marine animals, and cause health hazards to residents near us. Unlike plastics, die-cast parts are mainly made from recyclable materials. On average, about 95% of the metal is recovered from recyclable parts, which makes it a sustainable material that can be used repeatedly without degradation. Thin-wall castings:Compared with sand casting and permanent molds, the die-casting process can produce thin-walled parts due to the high pressure during the injection process. This allows a lightweight structure and eliminates or reduces the need for secondary operations. Insert casting:The die casting process allows inserts to be cast to form certain features, such as threaded inserts, heating elements or high-strength bearing surfaces. Die-casting parts can be used to make shells bought for     Lamps and lanterns  , automobiles, motorcycles, auto parts, luggage, medical equipment, etc., and are widely used. We supply non-ferrous metal die casting products such as aluminum alloy die casting and zinc alloy die casting.

    Preparation and application of metal plating for casting metal materials: Metal material plating is the whole process of spraying molten corrosion-resistant metal material to the metal surface with air compression or rare gas to produce a maintenance coating. When metal materials are coated, the raw materials of the coating are melted and atomized in a professional spray sink or paint spray gun, and sprayed onto the raw materials of the substrate. This type of surface decoration is sometimes called metal material painting. Oxyacetylene flame is generally used, but sometimes other vapors are also used. When the coated iron wire is automatically fed according to the flame core, the iron wire is melted and additionally atomized by the compressed air stream and sprayed onto the base material. Basically, any metal material that can be made into iron wire can be plated in this way. Another spray gun uses powdered raw materials to spray out according to the flame. The advantage of this type of method is that not only can be coated with metal materials, but also can be coated with metal ceramic polymer materials, metal oxides and cemented carbide tools. Preparing the surface layer before plating: The fusion between the plating raw material obtained from the metal material plating and the substrate raw material is purely broken mechanical equipment. Therefore, the substrate raw material must be properly pre-solved. Facilitate the integration of excellent machinery and equipment. No matter which surface preparation method is used in advance, the substrate surface must be cleaned without oil stains. The common way to prepare the surface in advance is the sandblasting process. Therefore, the sand grains are sharp enough to create a truly uneven surface. For the surface of a cylinder that can rotate on the side of the lathe, a reasonable way is to turn out a very thick external thread, and then gently extruded with an extruding knife Tooth crest. One improvement that can be used in the plan view is to use a round grooving knife to cut out a series of parallel-faced grooves, and then use a knurling knife to capture the center of each groove. If the plated surface layer is also to be produced and processed, the substrate surface layer should be prepared in advance by preliminary processing or grooving to facilitate good preparation in advance.

    Die casting is a type of metal casting that uses the process of pressing molten metal into the two steel molds that make up the casting. Die casting is commonly used in mass production and is known for producing high-quality, consistent products. The equipment used for the die-casting process generally has a higher initial cost compared to the process using sand molds. However, the daily production costs using die casting are often at a lower level, so the cost per product is lower. Modern methodLow pressure die casting is performed using a vertical process, which sprays molten metal upward against gravity. The metal passes through the blast furnace under the piston through the shot blasting chamber and enters the two dies under low pressure. These two molds are made of aluminum alloy. One is fixed, while the other can be pulled apart so that the casting can release itself from the mold once it cools. As the metal cools, the pressure in the mold remains unchanged to ensure uniform and accurate filling. As the metal cools, more molten metal can be added to fill any missing or shrinking cavities. The only disadvantage of low pressure is that the casting cycle is slow, but compared with high pressure die casting, this die casting process is a cheaper and simpler technology that can be automated. When it comes to this metal casting method, high pressure die casting is a new craze. In contrast to low pressure die casting, high pressure die casting has a shorter casting cycle and utilizes a horizontal casting process rather than a vertical casting process. High-pressure die-casting is formed by two machine plates on both sides, which are locked together to form a mold in the middle, just like a die-cast sandwich. A piston is used to push the molten metal through the cavity at high speed and high pressure to fill the mold. After the metal has solidified, open the mold and remove the casting. Due to the expensive nature of the machine and its molds, high-pressure die castings should be reserved for mass production. Although this new trend has accelerated the process, there are still some drawbacks in using high pressure die casting. High pressure die casting is a big investment, while low pressure die casting is a cheaper option. The process is also limited to smaller parts, because the locking mechanism can only bear a certain weight. However, this has led to the ability to use aluminum alloys to make lighter and stronger castings, a change that brings to other industries (including automotive, aerospace, electronics, and general hardware) that seek to minimize the weight of their cast parts and components Great benefits. Why choose vibration die castingAfter the die casting process is completed, the casting is moved for further processing or quality inspection. In some cases, if the standard is not met, the casting will be sent back to the furnace for melting and recycling. This process requires a vibrating conveyor and feeder system to move the casting to where it needs to be. Why is vibration better? The answer is simple. Belt conveyors simply cannot handle that much volume and wear out quickly. Vibrating conveyors and feeders can handle larger castings and scrap without being damaged or melted by heat. Aluminum alloy die-casting, zinc alloy die-casting and other non-ferrous metal die-casting products can be manufactured as excellent housing accessories for  Lamps and lanterns   , LEDs, locks, joints, elbows, strollers, belt buckles, hardware accessories, etc. Jiaxing Yunhe Trading Co., Ltd. is a professional manufacturer and supplier of lamps and lanterns.

Hardware Fitting : What Is Die Casting

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.
