Generally, medium temperature wax is combined with silica sol shell making process, while low temperature wax is generally combined with water glass shell making process! The shrinkage of the medium-temperature wax is greater than that of the low-temperature wax because the low-temperature wax paste contains water vapor. If the difference, I just know that the size of the medium-temperature wax is more stable than that of the low-temperature wax, the price is more expensive!
The purpose is to make the surface temperature of the molding powder cylinder constant in 98 ~ 120 ℃ forming the required temperature range. Since the laser sintered powder at the beginning, the heat accumulation in the forming cylinder is less, so the heater needs high power heating. After a certain layer of laser sintering, forming has certain heat accumulation in cylinder, so the heater power is reduced, so that we can ensure constant upper and lower the temperature at which the molding, to prevent the bottom thermal deformation, improve the quality of molding.
秒速时时彩The medium temperature wax has good solubility with other waxes. Low shrinkage, good fluidity and molding, fast solidification speed, smooth surface of the mould material; Good toughness, high strength, repeated use, stable performance, slow aging speed; Uniform and stable thermal expansion, small expansion force, high precision of products; This product is a new mould material with low impurity content and high quality.
However, the candle still needs to be further improved. Its material is usually animal grease with many defects, which is solved by schweill et al. Between June and July of 1809, a letter from a textile factory was sent to kejiasheffler, France, asking him to analyze and determine the ingredients of a soft soap sample they had sent.
T98 mold material is the production of wax material filling type, low gray matter, high surface finish, dimensional accuracy and stable characteristics, the melting temperature is 87-93 ℃ of wax material, mixing, the wax material under stirring temperature down to the injection temperature, injection temperature 60-66 ℃ T98 recycled material is only allowed for injection mold level 3, 4, 5, and 6 sprue cup part of guide vane group
