Our heating mantles made of alkali-free glass fiber insulation material, the Cr20Ni80 alloy wire spring installed in them, with aluminum silicate cotton by the vacuum shape of the hemispherical insulation body insulation. Each mantle is made with extreme care and is hand sewn to assure its reliability, quality and safety. Maximum heat transfer to the sample is achieved by having excellent insulation around the cartridge and good flask coverage.
1.Exclusively using special mould to finalize the design by vacuum filtering the Aluminum silicate wool and to add glue and to dry to make the hemispherical thermal insulator.
2.Aluminum alloy shell tensile heat resistance, corrosion resistance, strong and durable
3.Then making the heating sleeve according to different dimension of flasks with international standards by Pure manual knitting method.
4.Semi-spherical heating with electric heating set, large heating area, rapid heating and high temperature.
