Longhua die-casting release agent is a polymer synthetic water-based concentrated release agent. It is suitable for high-pressure die-casting processes of non-ferrous metals such as aluminum, zinc, and magnesium. It is matched with Longhua's full range of cold chamber die-casting machines and is compatible with manual spray guns, robot sprays, and integrated spraying equipment. It is widely used in the production of automotive parts, communications, electromechanical, and hardware die-casting parts.
How to use
1. Stir and shake the original solution thoroughly before use;
2. Dilution reference ratio (volume ratio)
-
Simple thin-walled aluminum alloy parts: 1:100~1:150
-
Conventional medium complexity aluminum parts: 1:80~1:100
-
Magnesium alloy / thick wall, deep cavity, difficult to demold complex parts: 1:60~1:80
3. Use an automatic sprayer or spray gun to evenly spray the mold cavity, core, and slider; the spraying pressure is 0.3–0.6MPa;
4. Allow sufficient drying and evaporation time after spraying, and ensure that the water evaporates completely before closing the mold to prevent pores;
5. Fine-tune the spraying amount and dilution ratio according to the mold temperature, cycle rhythm, and casting defects. A thin and uniform film layer is preferred to avoid excessive accumulation of material during spraying.
Things to note
1. When using this release agent, the mold should be cleaned first.
2. The amount of spraying should be appropriate, and the film is too thick: the peeling film is formed slowly, and the solution flows and swirls, which can easily cause wrinkles and deposition on the gas and liquid surface. The film is too thin: local oil film rupture occurs, and the film release is not good, which can easily cause marks and bites on the surface of the casting.
3. Shelf life: 6 months
4. Packaging method: 20Kg/barrel, 200Kg/barrel
