How to Avoid Aluminum Alloy Casting Error

Aluminum alloy casting errors will inevitably occur, but aluminum alloy casting errors have subjective and objective reasons. Next, a brief discussion of objective reasons and solutions. The error caused by the objective causes of aluminum alloy casting is mainly divided into three parts: CNC operating system error, mechanical error and tooling error. 1. CNC system error. According to the control mode of the servo system, the aluminum alloy casting system can be divided into open-loop control system, closed-loop control system and semi-closed-loop control system. The closed-loop control system can detect the actual position of the tool in real time, and feedback the result to the CNC system, and compare the feedback value with the command value in the system

What are the relevant requirements for aluminum alloy casting

Compared with manual processing, aluminum alloy casting has great advantages. For example, the aluminum alloy parts cast by aluminum alloy have very high precision and good repeatability; aluminum alloy casting can produce parts with complex shapes that cannot be completed by manual processing. What are the relevant requirements for aluminum alloy casting? Let's take a look. 1. the use of aluminum alloy casting environment. In order to improve the service life of aluminum alloy casting, it is generally required to avoid direct sunlight and other heat radiation, and to avoid being placed in places that are too humid, dusty or corrosive. Precision aluminum alloy casting should be far away from vibration equipment, such as punching machines, forging equipment, etc. 2. good

Briefly talk about the advantages and properties of gravity aluminum alloy casting

Due to the low melting point of aluminum alloy and good casting performance, gravity casting is widely used in automobiles, motorcycles, motors, communications, hardware tools and other fields. Gravity casting products are widely used in our lives. High-quality products make our products more worthy of consumption. Trust, let's introduce the detection methods and advantages of gravity aluminum alloy casting. Detection method of gravity aluminum alloy casting: gravity aluminum alloy casting usually adopts penetration inspection and coloring inspection. The surface of the casting is infiltrated or sprayed with a highly permeable colored liquid. The penetrant penetrates into the opening defects, quickly wipes off the surface penetration layer, and then sprays an easy-to-dry color developer on the surface of the casting,

Processing steps of aluminum alloy casting parts

Due to the different shapes of aluminum alloy castings, different cleaning methods are required. The flexible shaft is cleaned in the casting pipe hole by rotating equipment, which is suitable for occasions where important castings cannot be heated by vibration. Next, we will look at the processing methods of aluminum alloy castings. And cleaning methods. The processing steps of aluminum alloy casting parts:(1) the aluminum alloy casting parts after solution treatment are heated to a set temperature and come out after a period of time. The method of slowly cooling in the air is called aging. Aging strengthening is completed at room temperature. Natural aging is completed at room temperature, while aging strengthening is completed after artificial aging after holding for a period of time in an environment higher than room temperature. Aging causes supersaturation

Process Flow of Low Pressure Casting

Low pressure casting is to place the mold in a closed holding furnace, and the cavity is connected with the molten metal in the furnace through the riser. When working, pressurized air is introduced into the furnace, and the molten metal flows into the cavity from the riser. After the molten metal solidifies, the compressed air in the furnace is released, and the unsolidified metal flows back into the furnace from the riser. Many of the parts we currently use are manufactured using low-pressure casting technology, such as aluminum wheels and blades in the core of the torque converter. The resulting castings have compact structure and good mechanical properties. The yield of this method is high, as with gravity casting products, the yield of this method is 70% to 80%. The production efficiency of the same product die-casting process is the gravity

What are the advantages of low pressure casting

Low pressure casting refers to the casting method in which the mold is generally placed above the sealed crucible and compressed air is introduced into the crucible to generate low pressure on the surface of the molten metal and raise the molten metal from the riser tube. Fill molds and control solidification. This casting method is well replenished and compact in structure. It is easy to cast large thin-walled complex castings without risers, and the metal recovery rate can reach 95%. Easy to automate. However, the equipment cost is high and the production efficiency is low. Generally used for casting non-ferrous alloys. So what are the advantages of low pressure casting? 1, low pressure casting pouring process parameters can be set and adjusted within the scope of the process, can ensure the smooth filling of liquid metal, reduce or avoid

Cooling Method of Die Casting Mould

In the die casting process, a high temperature metal solution is forced into a mold cavity, which is cooled by heat exchange with the mold. The die-casting mold should absorb the heat brought by the high-temperature metal solution and dissipate the heat of the die-casting machine through the space. Generally speaking, the heat absorbed is greater than the natural heat dissipation, so the mold temperature will gradually increase with the die casting process. If the mold temperature is too high, it will affect the casting quality and mold life. In order to carry out normal die casting production, it is necessary to keep the mold temperature substantially constant. Cooling method of die-casting mold. Commonly used cooling methods are: extend the die-casting cycle, spray release agent or coolant, or open a cooling channel in the mold, with cold

The difference between die casting and lost wax casting process

Both processes belong to precision casting, which are very different and are completely different from the two casting processes. Die-casting The molten metal is poured into the steel mold of the die-casting machine and extruded by the die-casting machine. The process is relatively simple and suitable for non-ferrous metal props with lower melting point. Here to analyze the difference between die casting and lost wax casting process. Wax casting is simply to make a wax mold first, then make a shell on the wax mold, then melt the wax mold, and then pour the metal liquid into the empty shell after the wax mold melts and solidifies. The process is complex and suitable for small and medium-sized castings of various alloys. Let's talk about the difference between die casting and lost wax casting process.
