Composition of release agent
For a better understanding, the basic composition of the release agent is described below, with special attention to the importance of the active release agent. Regarding these process-related materials, today's most advanced release agents are distinguished based on three basic components, which themselves can exist in many variant forms. The most widely known and oldest mold release agents include oils and greases. As early as the early 1950s, when industrial pressure casting appeared, new compounds from the petroleum industry at that time could be used as basic raw materials. Initially, the pressure die casting process was assisted by the use of anhydrous mold release agents, which usually consist of oil, fuel, grease, and various mixtures of these substances. In modern die casting technology, due to the high requirements of the industry for process requirements and reproducibility, only mineral oils with specified fractionation can be used. Here, mold release agent manufacturers can choose from a variety of mineral oils, semi-synthetic and fully synthetic products.
In addition, oils from renewable resources, so-called ester oils, are increasingly used in the field of die casting. In addition to being renewable and having a positive impact on carbon dioxide emissions, ester oils also exhibit chemical and physical properties, which constitute a useful complement to the petrochemical industry derivatives series. The selection of the above-mentioned oils is based on process requirements, product prices and the experience of the mold release agent manufacturer. The advantage of all the above oils is their good application effect on tools. However, the heat application area of all oils used in die casting is predetermined and limited by the maximum allowable mold temperature. The second type of release agent known since ancient times is wax. Natural compounds of this class include beeswax and wax-like compounds derived from plants. Because the mold is filled with liquid metal and the temperature is about 50 degrees Celsius, the process conditions for pressure die casting are very harsh. At 600°C and high metal flow rates, the use of natural wax in pressure die casting is limited.
Due to the rapid development of crude oil fractionation and petrochemical industry, wax can also be produced synthetically. This opens up a whole new range of possible applications, because synthetic waxes can not only be used and delivered in large quantities, but can also exist in the form of countless compounds with the most diverse chemical and physical properties. The most widely used wax compounds in die casting are based on polyethylene and polypropylene waxes. Over time, these substances have proven to be the best and most suitable variants for non-ferrous metal die casting.
Pay attention
Like oil, the correct choice of wax is based on the process requirements and experience of the mold release agent manufacturer. The most advantageous properties of currently used wax compounds are good flow promotion and good adhesion to molten metal, especially in the gate area. This is usually the area where the highest flow rate (see flow rate in die casting) is reached. Therefore, good adhesion of the release agent is particularly important, because insufficient adhesion can lead to metal welding, which leads to increased cleaning requirements associated with corresponding tool wear. Compared with the above oils, another advantage of using wax in die casting is that the wax compound has higher high temperature resistance. According to their chemical composition, the wax in the release agent mixture can also provide good release ability at a higher tool temperature than the oil used. In addition, water-based mold release agents have a higher dilution rate than oil-based mold release agents. Like oil, the lubricating effect of wax can be considered very good. However, for release agents with high wax content, it should be noted that according to the flow rate and geometric design of the die-casting parts, they will form so-called oil-carbon deposits in the mold cavity. ingredient. In addition, wax-based release agents show a tendency to deposit in the central supply system because certain wax compounds have low shear stability. Another criterion to consider when using wax-based release agents is that the spray tools and mold fixtures may be contaminated.
