Tungsten Heater and Bottle Lid

Tungsten heater is used in vacuum coating furnace, which is widely used to coat the surface of bottle lid. With the development of bottles and lids, beauty is not the only target now, fashion, anti-artificial, different are all the targets with the times going.

There are many kinds of bottles for storing different liquids, for example, alcohol, wine, beer, drinks, milk, soybean milk, water, etc. besides the liquid which can drink by people, the bottles can also be used in chemicals, medicals, etc. All the bottles are sealed by the lid, which is colorful and practical. Before stamping or engraving names, letters, images on the lid, coating is mostly applied to improve its appearance beauty, decoration, anti-oxidization, anti-artificial, anti-wearness, electricity conductivity, etc.

About the coating, colors with red, green, gold, blue, orange, grey, mixed colors, etc. are all can be plated by the vacuum coating. Besides above, double coating, mixing with chemical elements with special properties can also be usable. And all the coating layers are all practiced in vacuum coating furnace, tungsten heater is one of the parts, which is used as heater to ionize the coating materials.

Heater in the coating furnace is made by tungsten, because of its properties of high temperature resistance, high purity, high electricity conductivity, low thermal expansion rate, etc. Due to its high purity and high temperature resistance, during its coating on the bottles lid, the purity of coating materials is not contaminated, and the heater can emit high heat and high temperature after charging electricity, so that the coating material can be gasified and plated on the surface of the lid quickly.

Heaters for the application of coating lids can be made with drawings, such as straight type, spiral type, etc. with single wire, double wires, three strands, five strands, seven strands, three plus one strand, and other customized types and strands. If you are making the lids for bottles, and owns the coating furnace, please do not hesitate to contact Chinatungsten to discuss heaters.
