Electric heater What are the classifications of
stainless steel Mica heating ring This product is made of 5261 stainless steel and mica 4102, which is not 1653 in production. It can be used for small-scale heating of nozzle and barrel of plastic machine. It has the characteristics of reasonable structure, beautiful appearance, stable performance, uniform heating, fast heat dissipation, long service life, good insulation performance and high voltage resistance. Widely used in injection molding machine, extruder and other plastic molding machinery.
(2) Ordinary Ceramic heating ring The shell of the product is made of stainless steel, which has the advantages of convenient installation, high temperature resistance and fast heat transfer. The working voltage is any value between 12V and 380V. It is widely used in household appliances (hair dryer), beauty instrument, medical instrument, industrial dryer, fax machine, etc.
(3) Crawler type ceramic heating ring: similar to the ordinary ceramic heating ring, the ceramic raw material is 95 red porcelain, and its temperature resistance effect is better than that of ordinary ceramic heating ring.
（4） Cast aluminum heating ring : the product is a tubular electric heating element as the heating body, bending components, into the mold casting aluminum into a variety of products. The utility model has the advantages of close fitting with the heating body, uniform heating, good thermal conductivity and long service life. This product is one of the ideal heaters at home and abroad. According to the needs of users, the insulation layer can be added outside the heater, the thermal efficiency is higher, and the power consumption can be saved by about 20%. It is mainly used for heating of plastic machinery, oven, water boiler, pipeline and non corrosive liquid.
(5) Cast copper heating ring: the process is similar to that of cast aluminum heating ring.
(6) Cast iron heating ring: the process is similar to that of cast aluminum heating ring.
(7) Brass heating ring: the product is mainly sealed by brass tube. The heating body adopts imported high temperature resistance wire and high temperature resistant mica plate, and the outgoing line adopts high temperature resistant fiber line and copper tape, which makes the outgoing line wear-resistant and durable. The wiring of the product is connected with the heating body with copper Mao and welded with silver fiber, so that the finished product is completely sealed.
(8) Hot runner heating ring: This product is used in the injection mold, which injects molten plastic particles into the cavity of the mold. Hot runner mold is widely used in electronic, automobile, medical, daily necessities, toys, packaging, construction, office equipment and other industrial departments.
