From the manufacturing of belt type filter press to ceramic filter and the vertical pressure filter of research and development and improvement, the development of pottery and porcelain, new materials, rubber and other industries, with expanded the business domain, has important influence on the world.

Toncin's complete set of equipment technology started from the research and development of the filter in the last century. In the 1990s, a new complete set of equipment technology, such as tailings dry drainage, was derived. The complete industrial chain makes Tongxing complete equipment technology have high cost performance and high applicability.

Through a series of research processes, such as physical research, material design, material processing, test and evaluation, Toncin has created new materials that can meet various needs and are widely used in solar energy, agriculture and other fields.

Toncin has expanded from solid-liquid separation field to environmental protection industry. Rubber dam and gas shield dam products have a very high market position in the domestic market, and they are also one of the main solid-liquid separation equipment suppliers in FGD field.
