Dalian Lushun Yumin Heater Manufacturing Co., Ltd. was established in 1985, and is a specialized manufacturer of non-ferrous metal casting and electric heating elements in Dalian. Our factory is fully equipped with production facilities, has strong technical capabilities, advanced processes, and reliable quality. Our products are sold throughout the country and exported to Japan, the United States, Africa, and Southeast Asia. The tubular electric heater is made by placing a metal resistance wire inside a metal tube and tightly filling the gap with electric-grade crystalline magnesium oxide powder, which has excellent thermal conductivity and electrical insulation. It features a simple structure, high thermal efficiency, good mechanical strength, and is lightweight and durable. Currently, it is widely used in ships, aviation, oil, chemical, food industries, and for civilian purposes. For aluminum castings, we use sand and metal molds for production, serving various domestic and international units, including those in the United States, Japan, and China, mainly applied in diesel engines, gas stations, and automotive parts. Over the years, we have been producing aluminum casting components such as discs and blades for central air conditioning systems for our customers, with these components being exported to Koki Holdings Co., Ltd. in Japan for use in large-scale central air conditioning systems. These products have earned a high reputation and praise from foreign customers over the years. Air rings are primarily used for air cooling in various plastic extruders and blown film machines. The various types of air rings produced by our factory have good aluminum casting density and are durable. The heater factory welcomes new and old customers to visit or contact us for business discussions. We will strive to adapt to the market, providing high-quality products and services at reasonable prices, with prompt delivery. We look forward to sincere cooperation with colleagues from all sectors, enhancing friendship, and achieving mutual growth.
