The liquid mold release agent of the aluminum billet casting equipment is the aluminum alloy industry
Aqueous and anhydrous release agent
Regarding die-casting, a distinction is made between water-based mold release agents and anhydrous mold release agents. They can be divided into three groups according to their basic raw materials.
The first group includes mineral oils, semi-synthetic and fully synthetic oils, and oils (ester oils) extracted from renewable raw materials. The oil has good spreadability on the mold, and the ester oil also has a good effect on the CO2 balance. However, the use of this type of oil is limited by the maximum allowable temperature of the mold.
The second group includes synthetic waxes produced from crude oil. Their special advantage is to promote good flow of molten metal and good adhesion (adhesion) on the mold. This is important to avoid metal adhesion. Other advantages are higher temperature resistance compared with oil, and good demolding ability at higher mold temperatures. However, wax-based release agents tend to form deposits.
The third group is relatively new and is based on R-polysiloxane-based release agents. They adhere well to the mold surface, promote the flow of molten metal and the formation of high-quality casting surfaces, and ensure that die-cast parts can be easily removed even at very high mold temperatures. Unlike wax residues on the surface of castings, R-polysiloxane-based release agent residues are relatively easy to remove due to their decomposition products.
Micro spray
Since the evaporating water of the release agent will cool the molding surface of the mold relatively quickly, cracks will form there, which will negatively affect the quality of the casting and the service life of the mold. If the amount of water is reduced and applied, the cooling effect—and thus the risk of crack formation—will be reduced. For this reason, and due to the ever-increasing requirements for the surface quality of die castings, micro-spraying technology has become more and more important. As a result, the thermal load is reduced and the mold life is increased. In addition, the lower consumption of the release agent helps reduce manufacturing costs. In addition, liquid residues are avoided, which also improves the quality of castings. The further development of die-casting alloys, the increasing requirements for die-casting design and surface quality, and the optimization of production processes will inevitably have an impact on the release agent. Therefore, manufacturers of release agents should also be busy with interesting development tasks in the future.
