Single-head electric heating tubes are widely used in many fields, especially in industrial heating equipment. Steel heating is used to present a single-head heating tube, which is called mold heating tube. In China's electric heating industry, the type of title: M3 It is called a cartridge heater in foreign countries. In the choice of acquisition, it should be selected according to the characteristics of the equipment. The conventional single-head heating tube has several types of threaded single-end electric heating tubes, L-type single-ended electric heating tubes, single-head heating tubes, etc. There are several types of high-temperature line type, external high-temperature line type, external high-temperature line, and direct-out type. Therefore, the choices are based on the environment and equipment used in the practice. The internal threaded single-head electric heating tube needs to know in the planning process of the single-head heating tube of the mold. It is planned to be a one-way wiring or a two-way wiring or a variety of forms. The choice of raw materials is also very important. Perhaps stainless steel pipes, etc., require a clear distinction between heating equipment. Inductive analysis of the different types of mold heating tubes, but the planning of materials and functions have a common point. The function requirements of the single-head electric heating tube of the mold are as follows: 1. The temperature rise time. At the experimental voltage, the component should rise from ambient temperature to the experimental temperature for no more than 15 minutes. 2. Rated power error. Under conditions of sufficient heat, the error in the rated power of the component should not exceed the scale of the following rules. 3. Insulation resistance. The cold insulation resistance should be no less than 50 megohms at the factory inspection. 4. Insulation withstand strength. The component shall be held for 1 minute under regular experimental conditions and experimental voltage without flashover and breakdown. to sum up. When selecting a single-head electric heating tube for a mold, it must be referred to the environment in which the equipment is used. It is also necessary to understand the characteristics of different types of goods. Refer to the article "Professional Threaded Single-Head Heating Pipe Manufacturers Introducing Commodities" to facilitate the selection of single-head heating tubes for molds. Jiangsu Huabang Electric Co., Ltd. has proposed to purchase single-head heating pipes for general molds. Most of them use external wiring methods. The lead wires cannot withstand temperature. It is easy to cause short circuit after being used in environments above 200 degrees. The single-head heating pipe for the mold produced by our company is from the internal lead wire. The single-head heating pipe is made of imported high-temperature wire and external terminalless processing technology, and the quality function is reliable.
