Standardized cleaning procedures for die casting molds and qual

  • Die-casting an aluminum alloy is one method that can be utilized in working pressure casting. The working pressure casting machine is put into use, the mold shell is put in place, the aluminum or aluminum alloy profiles are heated until they become liquid, and then they are put into the entryway of the die-casting machine. Following the aluminum die-casting process that the die-casting machine performs, the necessary castings are then cast.

    Aluminum castings that are heated to an excellent temperature maintain the excellent flowability of aluminum alloy die casting shape memory alloys, which in turn lowers the amount of structural stress and prevents cracking. The nature of the raw material being used and the requirements of the ingot serve as the primary factors in determining the casting temperature. If the temperature is not maintained at an appropriate level, the casting will experience an increase in its internal stress, which will result in the formation of cracks. It does not work, regardless of the temperature, and then it cold separates on the surface of the ingot, which results in flaws such as slag and even cracks.


    Additionally, the surface area die casting mould is a very important factor. Even though the aspect ratio of the liquid surface is becoming more and more suitable, the column lift of the ingot does not work because the surface of the liquid is too high. The surface of the casting that is not used in the production process should have a glossy and smooth finish. After being cleaned with tap water, the surface of the casting ought to be level with the casting and should bear distinct markings. The processing technology dictates the specifics of the cooling method, with the rate of cooling serving as the primary control variable. In general, the rate of cooling after annealing is slower than the rate of cooling after normalizing, which is faster than the rate of cooling after heat treatment, which is also faster than the rate of cooling after heat treatment. However, the regulations change significantly depending on the type of steel being used. For instance, hollow-hardened steel can be cooled at a cooling rate, such as normalizing. This will result in the steel becoming less brittle.


    The unreasonable design of the die casting company is responsible for a number of the shortcomings of die castings. These shortcomings include, but are not limited to, shrinkage cavities, shrinkage porosity, pores, lack of material, lack of casting, burrs, and so on.The stomata have a smooth interior, but the lumen of the shrinkage cavity has the shape of a peripheral nerve, and it is located at the end of the dendrite.The term "shrinkage porosity" refers to a type of metal mold casting in which the range of final solidification of the casting has not obtained the solvent of the metal material, and the dispersion and tiny small round holes are established. These holes frequently appear at the junction of the thicker cross section of the casting and its thin and thick cross section or at the thermal connection point.superior.The total area of shrinkage porosity is significantly larger than that of shrinkage holes, and while it is typically concealed within the casting, it can at times be so small that it cannot be seen with the naked eye.
    Because even the presence of a single blowhole or shrinkage porosity can result in major defects, not to mention a variety of other deficiencies, it is imperative that the design plan of the die casting company be given careful consideration.It is important that the cross section of the extrusion part be made smooth in order to ensure that the die-casting part can be solidified in a smooth and even manner.It is recommended that the acute angle arc be designed to the greatest extent possible, as this can reasonably increase the solidification rate.Dongguan Die-casting Factory conducted an investigation of the processing plant and found that the die-casting molds in the aisles and workshops in the industrial plant are basically filled with the relatively limited indoor space of the workshop, but they are just waiting to be cleaned. This information was discovered as a result of the investigation of the processing plant.


    Some businesses don't bother to clean the mold completely after each use because they calibrate and re-use the mold as soon as the manufacturing process is complete. If there are no other issues with the operation of the mold, it is safe to assume that the zinc alloy die casting parts that have been produced are clean. In the event that things continue as they are, there will be China die casting manufacturer a momentary shift in the company's cultural and industry awareness toward firefighting. Also, just passing through here.


    Some manufacturers will hire some junior and intermediate technicians or students from mold workshops to do some cleaning of molds and templates when they are cleaning and repairing die-casting molds. This is done so that the molds can be used again. When cleaning the molds and templates, however, die casting aluminum the track marks will also be washed away. This makes it difficult for maintenance professionals to see the molds and parts in order to properly repair them after they have been damaged.


    It is not necessary to be an experienced mold making technician in order to clean the mold; however, if a novice who is unfamiliar with the specific function and limitations of the mold as well as the characteristics of the important closed area of the mold attempts to clean the mold, the task will be fundamentally challenging. It's a very risky choice to make. It will result in molds with characteristic problems due to an unscientific division in the mold cleaning work, and at the same time, it will result in increased seams, burrs, edges, premature electroplating process or steel movement and mold mixing, etc. , as a result of increased seams, burrs, edges, etc. It is common for these kinds of issues to originate from a culture of temporary fire-fighting maintenance, which never monitors or carries over deficiencies and fails to identify the underlying cause of the problem. It is important to pay attention to cleaning the mold; in order to better achieve the overall goal of cost-effectiveness, it is important to formulate a specific plan for cleaning the mold. This will help. When cleaning the die-casting mold in its various positions, such as the internal cleaning of the press, the scrubbing of the large channel, the basic cleaning, and the cleaning of the key parts, the steps that are taken to clean are also distinct from one another. frequency. As a result, it is essential to keep track of the safe operation time of the mold and to file the observation reports of the accumulation of residues and damage inside the mold. In addition, the safe operation time of the mold should be documented.
