Zhuhai 4U Electronic Ceramics Co., Ltd.

Zhuhai Huiyou Electronic Co., Ltd Lies in Zhuhai, a coastal city in south of China′s Guangdong Province. The company is one of the major electric ceramic producers in China, specializes in the research and development and manufacture of ceramic heaters with most varieties in China and introducing production, testing and monitoring equipment advanced at home and abroad. Our company owns the large assembly line and sintering, brazing, slicing and milling equipment advanced in the world and employ strict procedure of routine test and random sampling and are equipped with well developed quality inspection equipment to control product quality at each stage.

Huiyou heating element always takes the lead in the trade. We have achieved many outstanding accomplishments, accumulated profound cultural deposits and integrated the advanced business concepts and management mechanisms for the new production technology and advanced equipment, it was identified the strict inspection according to SGS and RoHS to ensure lead the domestic industry in product quality, technical merit and service level.

Our ceramic heater is made by printing resistance slurry into the alumina raw ceramic pieces, then burn it under 1700 degree and get the nickel lead wire welded. In this way, the product comes to be a medium low temperature heating element, serving as a new product replacing heating alloy and PTC heating element heating element. It′s widely used for medium and low temperature heating in agricultural technology, communication, Medicare and routine life, such as ventilator, heater, heating auxiliary to air-conditioner, industrial drier, air dryer, electric heating splint, electric iron, direct/curving hair iron, vacuum flask, electric cooker, water heater, industrial drier, electric bonder, capper, UTR cylinder condensation-proofer, IR physiotherapy equipment, intravenous injection heating, quick food backing, mini thermostatic bath for special crystal parts. etc

Our ceramic heater is available in alumina and has many excellent features that do not exist in the sheath heaters.
