Product Application Overview:

Heating sheet, a sheet-shaped electrical component, is mainly used to efficiently convert electrical energy into heat energy. Thanks to its cost-effectiveness, ease of use and installation, and environmentally friendly characteristics, this component has been widely used in many heating applications.

Product Highlights:

Made by chemical etching technology, this heating sheet is exquisitely designed, with smooth edges and no burrs, smooth and wrinkle-free surface, and can maintain the stability of resistance value. Its manufacturing process is efficient, quality control is strict, cost-effective, and cost-effective.

Heating sheet etching advantages:

Through chemical etching technology, the film of the resistance heating sheet can be quickly drawn within two hours, greatly reducing costs and production cycles. This technology also supports half etching on the metal surface, which is convenient for adding company logos, strengthening brand recognition, and preventing counterfeiting.

Etching technology accuracy:

This process can ensure high-precision processing of resistance heating sheets with an accuracy of up to 5 microns, ensuring the stability of processing quality, clear batches, and strict quality control to meet the specific requirements of different customers for resistance values.

The ultra-fine laser drilling method uses the beam generated by the laser to evenly cut a thin line of only a few microns deep on the designed solid line, dotted line, wavy line, and easy-tear line. Taking advantage of the laser focusing, the focusing degree can be as small as the sub-micron order of magnitude, so it has advantages in the micro-processing of materials, and the cutting, marking, scribing and drilling depths are controllable. Even at low pulse energy levels, a higher energy density can be obtained to effectively process materials. Laser equipment can be used in slitting machines or rewinding machines, and laser technology can be used for flexible packaging materials such as OPP, BOPP, PE, PET (polyester), aluminum foil, and paper.
