Warm congratulations on the launch of the revamped website of Taiwan Da Fa Spring Industry Co., Ltd!

The world's first patent for a cone crusher was published in 1878, and it wasn't until 1898 that a product was made. The United States began using cone crushers at the end of the 19th century. The spring cone crusher was designed by the Simmons brothers from Milwaukee, USA, hence it is named the Simmons cone crusher. This machine has a history of about a hundred years; although it has gradually improved and its structure has become more refined, the basic structure has not undergone significant changes. In 1954, China designed and produced the 1200 spring cone crusher based on the Soviet Union's 2100 and 1650 spring cone crushers. In 1958, a large 2200 spring cone crusher was also designed and manufactured. After years of repeated research and practice, the old series of spring cone crushers overcame issues such as insufficient spring pressure, low component strength, and certain structural flaws. Currently, the mass-produced spring cone crushers come in five specifications: 600, 900, 1200, 1750, and 2200, with 14 different cavities. Compared to similar crushers from advanced countries, domestic spring cone crushers still have gaps in quality and performance. To catch up with the world's advanced level, domestic heavy machinery factories have introduced the Simmons and rotary cone crusher technology from the American Nordberg company and collaborated to manufacture this series of cone crushers. The basic parameters specified by the new standards for cone crushers are also comparable to those of the Simmons cone crusher. Therefore, the spring cone crushers produced domestically in the future will essentially be Simmons crushers, and older products will gradually be phased out. The Simmons cone crusher developed and manufactured by Dawn Heavy Industry is based on the introduction and absorption of foreign technology, designed and developed according to customer needs, and based on the principles of laminated crushing and the concept of more crushing and less grinding. It integrates high swing frequency, optimized cavity shape, and reasonable stroke into a modern high-performance spring cone crusher. Practice has proven that the CS series high-efficiency spring cone crusher, with its excellent performance, reliable quality, and high cost-effectiveness, has won the trust of users worldwide and is an ideal substitute for traditional cone crushers. Dawn Heavy Industry leads the development of domestic spring cone crushers with its own brand, technology, and strength.

Yesterday, the opening ceremony of the 2011 National Spring Industry New Products, New Technologies, and Technology Information Exchange and Exhibition was held for the first time in Dongguan, where dozens of domestic and foreign spring manufacturing companies gathered to exchange new technologies. The exhibition was jointly organized by the National Spring Standardization Technical Committee, the General Parts Product Quality Supervision and Inspection Center of the Machinery Industry, and other institutions. Well-known spring manufacturing companies and experts from Italy, Japan, and Taiwan participated in the conference. A representative from a spring manufacturing company in Dongguan stated that there are currently dozens of spring manufacturing companies in Dongguan, but the overall technical level is not high. Many companies survive by competing on price, and those that want to grow need to improve their technical capabilities. The exhibition serves as a great platform for technical exchange and learning.
