In the die-casting process of metal materials, in order to prevent the product from sticking to the mold or getting stuck in the mold, to ensure the quality of the product surface and to improve production efficiency, a surface release agent is needed to reduce the friction between the die-casting metal and the mold, and to produce smooth and bright high-quality die-casting parts. At this time, aluminum-magnesium alloy release agent becomes an ideal choice. This release agent is a high-quality water-soluble die-casting release agent that can form a dense, high-temperature resistant multi-molecular film layer between the casting and the mold, and has strong demolding ability; it effectively solves many problems such as difficult demolding, poor surface effect, and easy carbon deposition of die-casting magnesium-aluminum alloy materials. In addition, it can also extend the service life of the mold and reduce the wear and damage of the mold.

Bogao ED-842 aluminum-magnesium alloy release agent

In order to meet the needs of different customers and applications in the market, Bogao Industrial Oil actively developed and launched high-quality ED-842 aluminum-magnesium alloy release agent. Our research team has a deep understanding of the working principles and lubrication requirements of various mechanical equipment in the metal, rubber, plastic and other manufacturing industries. Combined with the unique properties of aluminum-magnesium alloy release agents, we carefully formulated the ED-842 series of aluminum-magnesium alloy release agent products suitable for different working conditions.

1. Product Definition

ED-842 is a high-quality water-soluble die-casting release agent that can provide a bright and clean surface for aluminum alloy and magnesium alloy die-castings. ED-842 can be fully emulsified in soft or hard water and can be used in fully automatic or manual injection systems. ED-842 will not clog the nozzle or leave a wax film on the mold. ED-842 is also a release agent that can be electroplated and painted in subsequent processes.

2. Product Use

Used for demolding and lubrication of magnesium-aluminum alloy die-casting that needs to be bonded or painted in subsequent processes.

3. Product Advantages

1. Good lubricity, which can make the surface of die-casting parts bright as new.

2. Excellent high-temperature stability, no mold scale residue in the mold, easy to clean.

3. It has the characteristics of low pollution and low smoke, shortening the spray time and die-casting cycle.

4. Strong demolding performance, making the workpiece easy to detach without deformation, reducing the workload of the die-casting machine.

5. It has excellent stability and chemical inertness.

6. Good water solubility, no stratification during long-term storage.

7. High solid content, high concentration, high dilution ratio, small usage, and low cost of use.

4. Product Use

In general magnesium-aluminum alloy die-casting processes, the dilution ratio is 50-100 times diluted with water. The specific usage ratio depends on the complexity of the customer's process. The dilution ratio can be increased by using automatic spraying. A lower dilution multiple should be used for high-difficulty demolding, pressure-free spraying or hand coating. For complex castings, it is recommended to spray a uniform layer of diluent on the mold after each demoulding to ensure easy demoulding for the next pouring.
