On April 27, 2026, the workshop of New Hongda Electric Heating Technology Co., Ltd. was a busy and orderly scene. After strict quality inspection, a batch of customized cast aluminum heating plates and cast copper heating plates for a large machinery manufacturing enterprise were officially loaded and sent to the customer's factory, marking the company's successful completion of delivery tasks in the field of customized industrial electric heating equipment services.
In many high-temperature scenarios of industrial production, such as mold heating, metal melting, and chemical reaction kettle heating, high-temperature single head electric heating tubes have become indispensable heating elements due to their small size, high power density, and rapid heating. To assist enterprises in precise selection, improve heating efficiency and equipment stability, this guide is specially formulated.
L Type Cartridge Heater is a special category of single head electric heating tube, named after its L-shaped corner structure. It inherits the core feature of a single head electric heating tube with one end leading out, and is suitable for heating scenarios where wiring at both ends is not possible, especially in devices or molds with limited space and corners, with significant advantages. It is composed of a metal protective sleeve, a spiral nickel chromium heating wire, and a magnesium oxide powder insulation layer inside. It is compacted by the shrinking process, which combines high thermal efficiency and mechanical strength. The heating speed is fast, and it can reach the working temperature in a few seconds to tens of seconds. The highest temperature can reach 300-400 degrees Celsius, and some special models can even exceed 760 degrees Celsius.
In industries involving corrosive liquid heating such as electroplating, chemical engineering, and pharmaceuticals, PTFE electric heating tubes have become the core heating equipment due to their excellent corrosion resistance. However, there are significant differences in the material, structure, power, and other requirements for products under different operating conditions. Scientific selection is the key to ensuring stable operation and extending the service life of equipment. This article provides comprehensive selection references for you from dimensions such as core parameters, structural forms, and scene adaptation.
Recently, Shenzhen Xinhongda Electric Heating Technology Co., Ltd. (hereinafter referred to as "Xinhongda Electric Heating") organized a public welfare team to travel to poverty-stricken mountainous areas in Guizhou to carry out a caring public welfare activity for left behind children with the theme of "warming up children's hearts and growing together", delivering materials and care to local children, and practicing corporate social responsibility with practical actions. Traveling thousands of miles, sending warm backpacks to children in mountainous areas
The Uniform Heating Cartridge Heater is an upgraded version of the ordinary Cartridge Heater, and its core advantage lies in achieving temperature uniformity in the heating section through a special wire winding process. Its heating wire has a higher winding density at both ends than in the middle. Although the heat generated at both ends is greater, the heat dissipation speed is also faster, which ultimately keeps the temperature of the entire heating section consistent. This characteristic makes it irreplaceable in scenarios that require strict temperature uniformity.
