The phase analysis is mainly based on the solubility and dissolution rate of various minerals in the ore in various solvents. Different concentrations of various solvents are used to treat the analyzed ore samples under different conditions, so that various minerals in the ore are separated. Thus, it is possible to measure the presence and amount of a certain mineral in a sample. Spectral analysis and chemical analysis can only find out the types and contents of the elements contained in the ore. It is not possible to indicate the presence of various compounds. Only through phase analysis and rock identification, can we know an element in the ore. What minerals are present. According to the available data, the following elements can be analyzed for phase: Copper, lead, zinc, manganese, iron, tungsten, tin, antimony, cobalt, bismuth, nickel, titanium, aluminum, arsenic, mercury, silicon, sulfur, phosphorus, molybdenum, germanium, indium, beryllium, uranium, cadmium and the like. The various elements need to be analyzed for which phases, and the relevant information can be found, and will not be described here. Compared with rock and mineral identification, which relies on microscopic analysis as the main method, the phase analysis operation is faster and accurate, but it cannot distinguish all minerals one by one. More importantly, it is impossible to determine the spatial distribution and embedding of these minerals in the ore. The mosaic relationship is therefore only an auxiliary method in the study of ore material composition, and it is impossible to replace the rock mineral identification. For the mineral processing staff, it is not necessary to master the technology of phase analysis. It is mainly to understand what elements can be analyzed by the phase analysis. Which phases should be analyzed for each element? Minerals exist? What are the options for various minerals? For example, a tungsten ore, spectral analysis only knows the approximate content of tungsten, chemical analysis knows the content of tungsten oxide, but whether the tungsten oxide is scheelite or black tungsten Mine, or both, must be determined through comprehensive analysis such as phase analysis and rock and mineral identification: if it is scheelite, re-election or flotation method can be adopted according to its embedding particle size; Generally, only the re-election method is adopted; if both are available, the heavy-floating joint method can be used. With these basic concepts, we can put forward reasonable requirements for the phase analysis, in order to correctly analyze and apply the phase analysis data drafting plan. If you can't do it now, don't send the phase analysis. Due to the complex nature of the ore, some elemental phase analysis methods are not mature enough or are still in the process of research and development. Therefore, it is necessary to comprehensively analyze the data obtained by phase analysis, rock ore identification or other analytical methods to obtain correct conclusions.

Vacuum casting offers a wide range of options for companies needing specific finishes,materials, or other features in their prototypes. We have the ability to simulate a full range of thermoplastics and elastomers, and we can also over-mold one
material over another to simulate, for example, rubber over ABS, or opaque plastic over transparent plastic. It is also possible to over-mold threaded inserts.
After casting, painting and printing is common, although polyurethane casted parts can be colored in the mold. EPT also specialize in producing high-gloss clear parts by using a CNC machined and polished acrylic master model. Polyurethane casted clear parts are very high quality.
We can create small and large urethane cast parts with production-like aesthetics and material properties for a range of applications, including medical and healthcare, military, automotive, electronics packaging, consumer products, and others.
