The advantages of CNC die casting in aluminum alloy die casting are as follows casting services

CNC is an abbreviation for computer-controlled automated machine tool


CNC is an abbreviation for computer-controlled automated machine tool. The control system is capable of logically processing the program specified by the control code or other symbolic instructions, and through computer translation, the machine tool is capable of performing the specified actions, and the blank is processed into semi-finished parts through the use of a tooling system. Intelligent inverse simulation system for numerically controlled machiningVirtual NC is a collection of software that, using inverse post-processors and virtual machine tools, simulates real-world NC controllers and machine tools, and checks the NC machining process on the computer's side. Input data from the machine, tool, blank, and fixture are used to simulate CNC machining programs, which helps to identify errors during the machining process.

Numerical Control (abbreviated: NC) technology is a type of technology that allows for the motion control of one or more mechanical devices to be accomplished through digital instructions composed of numbers, characters, and symbols, rather than through analog signals. Numerical control is often referred to as computer numerical control, abbreviated CNC, in the United States, and numerical control is commonly referred to as CNC machining services in other countries. Numerical control is generally implemented using a general-purpose or special-purpose computer to realize digital program control.

CNC has a number of advantages, including: 1. high processing precision and consistent processing quality; 2. multi-coordinate linkage, which can process parts with complex shapes; and 3. high processing speed.

3. When processing aluminum alloy die castings, it is usually only necessary to change the numerical control program, which reduces the amount of time spent preparing for production.

4. The machine tool itself has high precision, high rigidity, low processing consumption, and high productivity (generally 3 to 5 times that of ordinary machine tools); 5. The machine tool has a high degree of automation, which can reduce labor intensity; 6. The machine tool has a high degree of automation, which can reduce labor intensity; 7. The machine tool has a high degree of automation, which can reduce labor intensity; 8.


6. Operators have high expectations for quality, and maintenance personnel have high expectations for technical proficiency.

Die casting leakage can be resolved in a variety of ways.

Distal or wall thickness pressure does not increase the specific pressure; 2. It can be debugged and judged using simulated filling or actual samples; 3. It is easy to use.

Improvements to the gating system that are reasonable;

3. Select a high-quality alloy.

Analyze whether air entrainment has occurred during the hot mold stage of the diecasting process. The alloy does not flow well and does not fuse well. Increase the size of the slag collection bag and the length of the exhaust pipe by a reasonable amount.

5. Using X-rays, locate hot junctions on the circuit board. If it is determined that the hot junction is the source of the leak, it may be possible to negotiate with the customer engineer to change the structure and reduce the thickness of die cast parts the walls. In addition, secondary extrusion can be used to solve the leakage problem that occurs during pyrolysis.

6. Make every effort to avoid machining or to use the smallest machining allowance possible.

7. Die castings are subjected to X-ray flaw detection to ensure that they are of high quality internally. Reduce the melting temperature to an appropriate level.

In addition, X-ray flaw detection is used to inspect the internal quality of die castings. Use of coatings that produce little gas; impregnation of die castings

9. To identify pressure test equipment, use qualified die castings to identify the equipment. equipment for routine maintenance and inspection;

Compression testing can be used to identify number 10. Increase the level of process protection and ensure that molds are repaired in a timely manner.

11. Plane found and checked for flatness. In order to maintain control over the manufacturing process, there must be sufficient pressure holding time. Squeezing should be avoided at all costs during the process.

What is the best way to deal with the problem of water leakage in die castings?

With the appearance treatment of aluminum alloy die castings, the goal is to select the most appropriate technology for the specific requirements and to obtain a high-quality film layer that meets those requirements. This is accomplished by selecting the most appropriate technology for the specific requirements and by applying it to the die castings. Due to the fact that various existing appearance processing techniques still have their own set of issues, we must first understand the fundamental issues that exist in each of the different processing skills.

1. The fundamental capabilities of chemical film formation.

As opposed to anodized film formation, chemical film formation is completely dependent on the chemical reaction that occurs between the treatment liquid and the workpiece, and therefore does not have the same effect as applied voltage. Pay close attention to the uniformity of the die casting's appearance when inspecting it. As long as the appearance components are consistent, it is possible to form a consistent treatment film layer. As a result, it is important to ensure that the composition of the magnesium alloy liquid is consistent, that the composition of the die casting is consistent, and that the appearance of the die casting is sufficiently clean. Particularly when thin-walled die-casting parts (less than 2mm in thickness) are treated with a chromium-free treatment fluid with low film-forming properties, the design of alloy fluid composition, injection speed, and model conditions that affect the uniformity of the appearance and composition of die-casting parts should be strictly controlled to ensure that die-casting parts are not damaged during the treatment process. The piece's appearance is consistent and stable throughout.

Two important abilities in anodic oxidation film formation are:

In contrast to chemical film formation, anodic oxidation film formation is carried out under the influence of an applied voltage, and thus does not impose as stringent requirements on the appearance quality of die casting parts as do chemical film formation does. It is always possible to find the optimal processing voltage and processing time for die castings, even when the surface has not been pretreated. This is especially true for die castings that do not have a pretreated surface. The effectiveness of the treatment solution is the most important consideration when it comes to anodizing film formation.

Die castings' requirements for appearance quality are reduced, and the release agent has the opportunity to enter the treatment liquid during the casting process. If the release agent does not match the selection of the treatment liquid, the agility of the treatment liquid will be compromised, resulting in failure. In addition, during the formation of the plasma micro-arc oxidation film, the temperature of the treatment liquid will rapidly rise, causing some treatment liquids to fail and affecting the appearance treatment in some instances. In order to achieve consistent anodizing film formation, it is necessary to carefully select the release agent and treatment liquid as well as to maintain the temperature of the treatment liquid at a constant level.
