In the die-casting process that is in use today, aluminum alloy die-casting parts and the processing that comes after them are unable to avoid the generation of batch front burrs. Furthermore, the removal of batch front burrs takes CNC machining parts a significant amount of time in the processing stage. Therefore, the ability to remove burrs in a quick and effective manner is the key to aluminum problems that alloy die casting factories face and attempt to solve.

1. The creation of front burrs in batches
At this point in the process, the aluminum alloy die-casting parts that have been produced as a result of the aluminum alloy die-casting process are frequently surrounded by useless appendages that are not required by the drawings. These appendages take the form of edges.As a result of the fact that the extra parts frequently cause some discomfort to the hands, they have edges, which are also vividly called edges.Burr.Different aluminum alloy die-casting factories have different cultures and local dialects, and as a result, the companies that work in these factories have different customary names.Some people refer to them as burrs, while in other parts of the world, they are referred to as flashes and overflows.The processing of aluminum alloy die-casting parts frequently results in the production of burrs and burrs.

Die-casting aluminum alloy components typically have front edges that are located on the parting surface of the die-casting mold; however, there are times when these front edges develop in the aging and cracked mold meat. Specifically referring to die-casting parts made of precision aluminum alloys, the following are some of the general reasons for the criticism:It is difficult to correct the design structure of the customer's product through mold design because the design structure is either overly complex or unreasonable. defects in the structural design of die-casting molds, illegal operations performed during the manufacturing process of die-casting molds, or unreasonable processing techniques, etc. In the event that the heat treatment is not carried out in accordance with the specifications, the hardness will be insufficient, which can easily cause mold meat to deform.

Die-casting mold is not properly maintained, debris in the cavity is not cleaned in accordance with the operating specifications, or the mold is not properly equipped with the necessary components. Because domestic aluminum alloy die-casting factories generally prefer to produce aluminum alloy die-casting parts at high pressure and high speed, the life of the die-casting mold will be greatly reduced as a result of the parameter selection of the aluminum alloy die-casting process. One example of this is that the casting pressure is too high. During the production process of aluminum alloy die-casting, the alloy materials that are on the surface of the mold are not cleaned on a regular basis.

The generation of batch fronts through the exhaust block is a normal phenomenon that occurs during the process of die-casting aluminum alloy. These batch fronts assist in the discharge of gas that is trapped in the mold cavity and help to reduce the amount of internal pores that are present in the finished product. However, if the sealing material in other parts of the mold is not good, more batch fronts will be generated with the die-casting. Additionally, energy loss and the loss of the high-pressure posture of aluminum alloy die-casting parts will not only cause internal shrinkage of the product and lead to large-scale scrapping, but it will also cause fly materials during the die-casting process, putting the personal safety of employees in jeopardy; therefore, steps should be taken to prevent this from happening.

2. During processing, factors that contribute to the formation of burrs
During some of the subsequent processing steps, die-casting aluminum alloy parts will also result in the production of burrs.Because of their size and pointy nature, they are frequently referred to as burrs.During the machining process, the reasons for burrs in aluminum alloy die-casting parts can be considered from the following aspects: whether the designed fixture is conducive to processing; whether the design of the tool is reasonable, such as whether the chip removal is smooth; whether the selection of tool materials is appropriate. If the designed fixture is conducive to processing, the reasons for burrs in the part can be eliminated.putting in orderThe design of the process is not logical at all.Are there any obvious issues with the processing parameters?A maximum feed of 2 millimeters is what the manufacturer recommends for a knife.During the actual processing, burrs will quickly appear at a rate of 5mm at a time.Burrs will develop on the tool if the wear is significant enough.The task has to be carried out correctly if there is to be no loss of time spent by employees.Management of the tool's useful life..

3. Common approaches to the removal of burrs from the edges of batches
Die-casting aluminum alloy parts often have jagged edges, which can have a direct impact on the final product's quality.Because of this, the most significant challenge that aluminum alloy die-casting factories face is figuring out how to effectively remove them.A significant amount of practical knowledge has been amassed over the past few years as a result of the extensive research on the techniques for rounding off corners and removing burrs that has been carried out by a variety of different industries.Statistics that are only partially complete indicate that there are more than sixty different ways to remove edges and burrs.

To remove the cutting edge, a blanking die should be used. When designing the blanking die, it is important to remember to take into consideration the zinc die casting manufacturer cutting edge of the aluminum alloy die-casting and to design it as a profiling knife edge. Remove the nozzle and the overflow port from the slag bag (riser), and then cut them off. Additionally, cutting off the product batch edge together eliminates the need for multiple clamping and reduces the number of manual operations, both of which contribute to a significant increase in operational efficacy. Burrs on the edges of batches are manually removed. Blanking dies that have a low degree of automation also have some drawbacks. They do not remove all of the edges of the product batch. In light of this, people are working very hard to achieve automation, but many factories still use the more traditional method of manually filing documents in order to get rid of blanks. The front should be criticized.

Steel files, sandpaper, and other simple abrasives are all that are needed for manual deburring; in addition, it does not require a large amount of personnel and is flexible and adaptable. The primary benefit of manual deburring is the low initial investment that is required, as well as the ease with which the necessary tools can be acquired. It has low efficiency and is related to the proficiency of workers; it is difficult to control the surface finish after deburring; workers are prone to fatigue and omissions after working for an extended period of time; some tools have high noise when removing burrs, and some tools are not wear-resistant. There is a significant amount of dust, and the potential for harm is very high.

A device known as a trimmer is typically utilized for work on the edges that are visible after finishing. After the planar surface has been processed, there are frequently some burrs around it. It is necessary to get rid of these burrs because they will lower the overall quality of the product and cause pain to people's hands. When compared to using files and sandpaper, which is a less efficient method, the use of the trimming knife is incredibly straightforward and has little to do with the worker's level of expertise. It is risk-free, quick, and convenient, and there is no pollution from noise or dust. The traditional methods of removing burrs, such as sharpening and filing by hand, cannot compare to the smoothness of the edges of the burrs that are removed using this method because it relies on chips. After processing, manual deburring with this tool is recommended first and foremost.
