Refers to the use of mass spectrometry and mass spectrometry instrument analysis, mass spectrum of samples to get samples of different mass spectrum graph represent data and physical and chemical properties, and quantitative analysis of samples and data representation, meet various scientific research institutes and enterprises confront demand spectrum instrument analysis. Other analysis: other than chromatographic analysis, spectral analysis, thermal analysis, and rustic analysis.


The medium temperature wax said that after dewaxing wax liquid static precipitation half an hour after the drainage. It is characterized by a narrowing of the line, using simple equipment. Good fluidity, rapid forming, good finish of waxy surface, high dimensional precision. Due to its characteristics, medium-temperature wax is more suitable for casting than low-temperature wax. In addition, the medium temperature wax mould containing high molecular organic matter should be completely burnt out, and the temperature should reach over 670. Does the color of car paint match the color of car wax?


In order to remove the residual alcohol, water and a small amount of organic matter in the residual wax and ceramic layer, and further enhance the strength of the ceramic layer, the roasting mold is required. It can be seen that the thermal expansion rate of sodium silicate sand sleeve is different from that of ceramic layer when heated. The ceramic layer expands slowly and continuously.


In this way, the ideal size of wax mold can be obtained, and then the casting can be obtained. Here, we are using PS powder as a molding material disappear, depending on the die casting material choose different scaling, if the pattern is used to cast aluminum, so overall amplification 1% to CAD model; If the vanishing die is used to cast steel parts, the overall CAD model should be enlarged by 2%. In the actual production process, by measuring the casting size, the wax mold size can be coordinated again, and finally qualified wax mold and casting can be obtained.


Casting refers to the process of smelting metal into a liquid that meets certain requirements and pouring it into the mold. After cooling, solidifying and cleaning, the casting process can be obtained with predetermined shape, size and performance. Casting refers to the process of producing a cast blank or part shape obtained by various casting and forming methods.
