The production of aluminum alloy die-casting requires the use of die steel. What is die steel? Die steel is a kind of steel used to make molds such as cold die, hot forging die, and die-casting die; then what is the demand for die-casting of aluminum die-casting? China Die Casting Parts Factory will talk about you:

First, high tempering resistance and thermal fatigue resistance

Generally, in the aluminum alloy die-casting production, the molds are continuously produced for a long time, so the temperature must not be low, but will reach the highest point, so the mold steel must have certain hardness and no sticking;

Second, sufficient strength, hardness, plasticity and heat resistance

Aluminum Alloy Die Cast Part is produced by pouring molten metal into the mold during molding, so the mold steel must have sufficient high-temperature strength and toughness;

Third, good thermal conductivity

The first point is that the mold is at a high temperature of 600-700 ° C for a long time, and good thermal conductivity is necessary;

Fourth, good resistance to damage of molten metal

It is also in a state of high temperature, high temperature casting melt damage, Die Casting Mould does not have a little damage resistance is not acceptable;

The life of die-casting molds is a point that all manufacturers care about. The long life of the molds is used. The more products are produced with the same specifications. If the life of the die-casting molds is short, it takes a lot of time to re-sample the custom molds. It is very troublesome, then do you know how to extend the die casting mold? The following Aluminum Alloy Die Cast Part Factory will tell you;

1. The quality of the mold is a major factor in determining the length of service;

2. Dimensions need to be designed reasonably and with inserts;

3. Re-stressing and tempering should be required after roughing;

4. For quenching and cooling, the steps must be continuous enough;

5. The profile of Custom Die Casting Mould shall not be highly polished and shall be oxidized;

6. The temperature of the aluminum liquid must be reduced as much as possible before obtaining a qualified product;

7. Do not spray too much release agent;

The above is the method to extend the service life of the die-casting mold, and I hope to help you.

A good Custom Die Casting Mould is very important. If the protection is not good, it will affect the service life and will affect the subsequent use. So, do you know the maintenance method of the die-casting mold? Aluminum Alloy Die Cast Part Factory to explain to you:

1. Reduce the speed of compression and reduce the impact of the mold as much as possible.

2. Reduce the temperature of the aluminum casting as much as possible, which will increase the service life of the Custom Die Casting Mould.

3. It is necessary to reduce the rapid cooling of the mold as much as possible and to produce as continuous as possible. In the indifferent state, it is not possible to shoot at high speed.

4. In the daily need to strengthen the maintenance of the mold, it is also necessary to do regular maintenance, regular tempering of the mold cavity.

5. When Custom Die Casting Mould is used, the cover should be cleaned and the aluminum skin should be cleaned in time to avoid squeezing the mold.

The above is the daily maintenance method of die-casting molds, I hope this article can help you.

Core Abstract: the aluminum alloy die-casting surface technology is rich and varied, and the aluminum alloy die-casting surface effect is very beautiful and fancy. let’s look at the other two polishing processes of aluminum alloy die-casting parts.

Two polishing processes for aluminum alloy die casting

The surface technology of aluminum alloy die casting is varied, and the surface effect of aluminum alloy die casting is very beautiful and fancy, let’s take a look at the other two polishing technology of aluminum alloy die casting.

1.Alkaline electrolytic polishing process for aluminum alloy die casting

The research on the alkaline polishing solution system was carried out, and the effects of corrosion inhibitors and viscosity agents on the polishing effect were compared.The alkaline solution system with good polishing effect was successfully obtained, and the first time was to reduce the operating temperature and prolong the solution. An additive that has a long life and an improved polishing effect. The results show that adding appropriate additives to NaOH solution can produce good polishing effect. Exploratory experiments also showed that the reflectivity of aluminum surface could reach 90% after using NaOH solution of glucose under certain conditions. However, due to unstable factors in the experiment, which needs further studies. The feasibility of using pulse electropolishing method to polish aluminum under alkaline conditions was explored. The results showed that the leveling effect of constant voltage electropolishing could be achieved by pulse electropolishing method, but its flattening speed is slow.

2. aluminum alloy die-casting and aluminum alloy environmentally friendly chemical polishing

It is determined to develop a new environment-friendly chemical polishing technology based on phosphoric acid and sulfuric acid, which is to achieve zero emission of NOx and overcome the quality defects of previous similar technologies in the past. The key to the new technology is to add some special-effect compounds to the base fluid instead of nitric acid. Therefore, it is necessary to analyze the chemical polishing process of aluminum triacid, especially the role of nitric acid. The main role of nitric acid in the chemical polishing of aluminum is to suppress pitting corrosion and improve polishing brightness. Combined with the chemical polishing test of pure mono-phosphoric acid, it is concluded that the special substance added in mono-phosphoric acid should be able to inhibit the spot corrosion, alleviate general corrosion,at the same time, have a great leveling and bright effect.
