· Tianjin Huitian Electro-Technology Co., Ltd. was established in 1993

· In 1994, the "new rotor internal mixer" developed in cooperation with Beijing University of Chemical Technology won the third prize of the National Invention Award and obtained a national patent.

· In 1995, the "new roller mill" developed in cooperation with Beijing University of Chemical Technology won the fourth prize of the National Invention Award and obtained a national patent.

· In 1996, we developed the first domestic silicone rubber special extruder and a two-stage silicone rubber hot air vulcanization drying tunnel, and obtained the national patent. This solved many problems in the production process of domestic silicone products in the past and greatly optimized the domestic production process. The production method of silicone products has greatly improved the quality and production efficiency of silicone products.

· Rated as a high-tech enterprise in 1997

· In 2003, the company's flagship product - silicone rubber extrusion and vulcanization production line, after achieving great success in the industrial and civilian fields, began to enter the medical, electric power, military and other fields, and also achieved extraordinary results. Launch Vehicle Research Institute, Beijing University of Chemical Technology, Shenyang Aircraft Group Well-known domestic and foreign companies and scientific research institutes such as Shandong Medical Device Research Institute, Northwest Rubber Research Institute, Japan's Cooliet, and South Korea's Sewun have successively reached cooperation with Huitian.

· Become the company with the largest domestic market share and have been recommended by domestic and foreign professional media such as China Chemical News

· In 2004, the silicone rubber extrusion and vulcanization production line entered the international market and was exported to many countries in Asia, Africa, Europe, and the United States.

· In 2005, new products such as silicone special open mill, vertical extrusion vulcanization production line, and silicone dipping machine were developed.

· In 2010, a major modification of the silicone extrusion and vulcanization production line equipment was completed, which improved product performance and reputation.

· In 2012, a micro silicone extruder was successfully developed, which can realize the extrusion of hoses below 0.5MM to meet the needs of precision and fine extrusion.

· In 2015, special extrusion technologies such as silicone variable cavity drainage tubes were successfully developed. On this basis, a variety of specially designed proprietary shapes were developed, overcoming the limitations of traditional extrusion technology. We are the only domestic manufacturer that can sell this technology. . Promote domestic products to completely replace imported products, achieve large-scale exports, and basically achieve the domestic monopoly status of such products.

· In 2016, sales of silicone rubber extrusion and vulcanization production lines exceeded 1,000 sets

· In 2021, the threaded pipe spiral extrusion system for silicone ventilators was successfully developed. All major domestic manufacturers of such products have purchased them and exported them to Taiwan, Brazil, India and other places.

· The special extrusion technology for silicone spiral drainage tubes has been successfully developed and is the first domestic manufacturer to develop this technology.

· The special technology for automatic co-extrusion of soft and hard silicone rubber (two-color segmented extrusion) has been successfully developed. It is the first domestic manufacturer that can realize industrial application.

· The silicone fully automatic diameter adjustment extrusion system (extrusion production line) was successfully developed. It is the first company in China to realize fully automatic adjustment of silicone pipelines to product size. The product accuracy reaches ±0.05MM, reaching the international advanced level.
