In comparison to earlier times, the die-casting molds for aluminum alloys that are produced in my country have achieved a significantly higher level of technological sophistication.On the other hand, the proportion of high-, middle-, and low-end products produced within the domestic mold industry is extremely unbalanced, which is very unfavorable to the development of the mold industry within my country.This is because my nation has a domestic mold industry that is on the smaller side in comparison to other nations.

Using the technology of laser surface treatment, it is possible to modify the surface of low-grade materials so that they have a high level of performance.Because of this, the resulting parts have the best possible combination of high-performance working surfaces and low manufacturing costs.The laser beam's power is unaffected by the laser's own inertia, and its intensity can be continuously adjusted without affecting the CNC machining beam's output.It is possible to perform local hardening on components that have complex shapes and other components that are difficult to process using traditional methods. This type of hardening can be done on a variety of different types of components.In addition to this, it is able to perform a wide range of laser hardening treatments on the different components that make up the part.

Because of its many advantageous characteristics, laser surface treatment is ideally suited for use on the surfaces of certain parts and local locations that are notoriously difficult to treat with more conventional methods of hardening (such as carburizing and carbonitriding quenching, nitriding, and high- and medium-frequency induction heating quenching, etc.). These parts and locations include those that are notoriously difficult to treat with more conventional methods of hardening.Particularly well suited is this method of treatment for areas that, when approached with more traditional approaches, are difficult to access.Therefore, strengthening treatment provides a number of distinct benefits in the process of manufacturing aluminum alloy die-casting molds. Some of these benefits include the following:

(1) It is possible to replace high-grade mold steel with low-grade mold steel or cast iron; (2) Use domestic mold steel to replace imported mold steel; and (3) Enhanced repair (remanufacturing engineering) can be performed on aluminum alloy die-casting molds to reduce the cost of manufacturing aluminum alloy die-casting molds. (1) It is possible to replace high-grade mold steel with cast iron; (2) Use domestic mold steel to replace imported mold steel; and (3) Use domestic mold steel to replace imported mold steel.The total cost of manufacturing aluminum alloy die-casting molds can be brought down to a more reasonable level by combining these three approaches.This has the potential to significantly cut down on the amount of time spent on design and manufacturing, significantly cut down on the amount of money spent on production, change the methods used to manufacture molds, and ultimately integrate and improve the entire mold industry.

Traditional technologies that are currently in use cannot even come close to competing with these advantages in terms of technology, economics, and providing better service to customers.In the manufacturing of mold cores, the process of laser melting is a technology that is utilized.
Because the laser melting of metals is becoming an increasingly important aspect of mold making, this technique enables the cooling opinions to be placed very closely underneath the contours of the mold. When working with complicated parts that have varying wall thicknesses and are fitted with reinforcing ribs and mesh ribs, it is possible to carry out cooling operations in close proximity to the contours of the part where cooling is required. 

This makes it possible to reduce the amount of time spent on the cooling process.In times past, it was not possible to achieve controllability over the material flow characteristics that occurred during the injection molding process. However, in modern times, it is possible to achieve controllability over these characteristics.The cross-section of the cooling opinion covers an area that is greater than 5 millimeters in width and depth combined.

As a consequence of this, the cooling opinion can be positioned between two and three millimeters zinc die casting products close to the contour of the mold so that the optimal amount of cooling can be achieved. Controlling the temperature can be accomplished with such an opinion; for instance, the temperature control that takes place in high-gloss mirrors (also known as the high-gloss effect) is an example. Certain molds even have the ability to perform two separate tasks at the same time by utilizing two separate opinion loops:According to one point of view, the temperature of the highly reflective, high-gloss surface can be controlled.

3. Laser welding is gradually replacing more traditional methods of mold repair, which are being phased out gradually.
Repairing die-casting molds that are made of aluminum alloy can be done in a number of different ways, including by utilizing the EDM process, argon arc welding repair, laser surfacing technology, the brush plating method, and a great deal of other options.Laser welding is currently making its way into the market as an alternative to precision mold repair that is both viable and cost-effective.The laser beam that is utilized in laser welding is brought to a point of concentration by a high-power coherent monochromatic photon flow, and this serves as the process' primary source of heat.One of the benefits of the process is that it does not require the work to be done in a vacuum. This is one of the advantages of laser welding.On the other hand, the penetration power of laser welding is noticeably lower than that of electron beam welding.

4. Increase the rate at which the modifications are being made to the structure
However, the proportion of high-, middle-, and low-end products produced in the domestic mold industry is extremely unbalanced, which is very unfavorable to the development of my country's mold industry. Although the level of mold technology in my country is significantly higher now than it was in the past, the proportion of high-, middle-, and low-end products produced in the domestic mold industry is extremely unbalanced.The mold industry in my country is dominated by low-end products, which is why this is the case.In spite of the fact that the structure and system of the mold industry in my country has been subjected to significant changes over the course of the last few years, the industry continues to place a primary emphasis on the production of molds that are medium- and high-end, as well as large, precise, complex, and long-life.

On the other hand, as a result of the overwhelming demand for molds ranging in price from lower to higher points, the self-matching rate for molds of higher quality in my country falls below 60%. This is due to the fact that molds are in such high demand.Imports are particularly important for the automotive industry when it comes to the production of key and core molds.In recent years, domestic businesses have continued to advance both the technology and the products associated with aluminum alloy die-casting molds. These advancements have been made possible by continued research and development.However, it is impossible to deny the fact that only a small percentage of companies have been successful in penetrating the international high-end market.
