What is the manufacturing process for heating pads using silicone heating wire

Each product has its own production and production process, including heating elements. Silicone rubber heating belt is a particularly soft heating belt composed of nickel chromium alloy wire and insulation material. Its design has high power density, fast heating, high thermal efficiency, and long service life. In addition to being used for heat tracing and insulation in general constant power bands, it can also be used in places that require heating in some cases. The PI heating film adopts an improved PI film, which has better thermal conductivity and can be customized according to design requirements. It can meet different heating power and temperature requirements in different areas, achieving temperature distribution on the heating surface. The electric vehicle battery heater uses the thermal energy generated by the auxiliary heater to heat the battery pack, which does not consume battery power and therefore does not affect the power and range of the electric vehicle. At the same time, it can also ensure the heat required by the air conditioning system. The vehicle controller distributes heat by controlling the opening of each electronic control valve, and the control method is simple. Today, let's learn about the production process of traditional heating wire silicon heating plates?

The production process of traditional heating wire silicone heating pads is actually relatively simple. It can be said that the vast majority of silicone heating pads are designed and produced on demand. Therefore, the first step in the production of silicone heating pads is to obtain customer requirements, including shape, width, length, and thickness; Power (referring to the amount of work done by an object per unit time), working temperature, lead length (default is 150mm, designed as needed), and temperature control devices can also be equipped as needed. Epoxy resin heating plate refers to a general term for polymers with more than two epoxy groups in their molecules. It is a condensation product of epichlorohydrin with bisphenol A or polyols. Due to the chemical activity of the epoxy group, various compounds containing active hydrogen can be used to open the ring, solidify and crosslink to form a network structure, making it a relatively thermosetting resin. Bisphenol A type epoxy resin not only has a large output and a wide variety, but also new modified varieties are constantly increasing and the quality is constantly improving.

The design of the shape is directly related to the design of various components of silicone hair gel. For example, the square 300mm x 500mm x 3mm silicone film on both sides can be made into 300mm x 500mm x (about 1mm). Then, according to the required power (referring to the amount of work completed by the object in a unit time), and based on the input power of the power source, the appropriate resistance wire is selected. The rated function and demand need to be calculated. After geometric operation, the heating wire is evenly distributed around an area of 300mm x 500mm. Then, high-strength fiber cloth is attached to both sides using the high temperature resistance, insulation, and stretching ability of the same area. Finally, professional machinery is used to press down the silicone film mentioned earlier to make it as a whole. Of course, do not forget to export the resistance wire lead. The length can be freely designed. The Chinese name for PCB heating board is printed circuit board, also known as printed circuit board. It is an important electronic component that supports electronic components and serves as the carrier for electrical connections of electronic components. Because it is printed electronically, it is called a "printed" circuit board. PCB heating plate is a type of heating equipment that uses electric heating alloy wire as the heating material, mica soft board as the insulation material, and is outsourced to thin metal plates (aluminum plate, stainless steel plate, etc.) for heating. Typical applications, such as electric water bottles.

Casting metal tubular heating elements into aluminum plates, aluminum plates, or welding or embedding them on aluminum plates and aluminum plates to form various shapes of silicone rubber heating belts and silicone rubber heating belts. Typical applications include rice cookers, electric irons, electric coffee pots, etc. In this way, the production of a more traditional heating wire silicone heating element has been completed, and the work of checking the sealing of the product and testing the power has been completed. This is slightly simpler than the new nano carbon based electric heating pad, but even if the processing principle is the same, the quality of the final formed product varies greatly due to differences in material selection and calculation accuracy.
