Mould heating pipe material selection of common sense, do you know about it

Want to know the material composition of heating tube need different production, only to ensure that all kinds of good raw materials, components, can guarantee the quality of the mould heating pipe products and performance. Let's take a look at the mold heating pipe material selection need to pay attention to the content of basic common sense.

All kinds of heating tube mould materials selection knowledge

First, now on the market of stainless steel materials into a lot of kinds, everyone in heating tube material of choose and buy when, must uphold the principle of heat resistance, corrosion resistance to choose from. Now usually heated mold can choose 304, 202 and 301, 302 stainless steel material, and the most commonly used liquid heater product is seamless 304 stainless steel material, its oxidation resistance, late performance is stable.

Second, selection of resistance wire is more critical, because now the mould heating tube to have efficient heating performance, so the choice of the resistance wire must be good. From the length, diameter and related dimensions are need to meet the requirements of the product and according to the resistivity of different material to calculate the final resistance value, can be sure that this kind of resistance wire can meet the demand of heating products.

Third, the choose and buy of magnesia powder, now the mould of heating pipe is filled by the high quality crystal magnesium oxide powder, so we must buy normal manufacturer of professional products, because if the quality problems of this kind of filler material or polluted, is affects the thermal efficiency of heating products, serious and may even lead to safety accident.

Fourth, the choice of sealing material is also a point of electric heating tube products, for this type of sealing material choice, different stainless steel material collocation of the sealing material differences. If you don't use high quality sealing material, can lead to water vapor into the heating device, thus lowered the insulation performance, tripping, short circuit, and other problems, for a long time not to use the sealing material, and may even yes nozzle is damaged, will cause the electric heat pipe scrap.
