This article researches and analyses the technology work, with the thought and method of group technology, in product development, manufacturing technology and modernized management of the enterprise to tackle challenges and competitions in the market.

A manufacturing process of high performance coated sand phenolic resin was introduced.

It discusses the feasibility of the manufacturing process and presents the actual manufacturing process and matters needing attention.

The manufacturing process is also described in detail in this paper.

Cherokee rose is a natural fruit used to produce liquor and the relative technical operations are simple including raw materials treatment, fruits grinding, steaming, starter preparation, cooling and bacteria culture, barrel entry fermentation, and steamer-filling roasting etc.

In order to ensure satisfactory Xiaoqu liquor production in winter,the following points should be highly valued: strict technical operation,strengthening production management,proper grains cooking and bacteria culture,increasing the use level of starter,pit entry fermentation at 28～32 ℃,addition fermented grains by searching vapour,and liquor steaming by moderate fire etc.

However, in order to produce base liquor of higher quality, we should make more effort in starter, pit mud, technical operation and liquor storage etc.

The raw material and process operation which affects the catalytic activity are analyzed and a method to enlarge the life circle of MTBE catalyst is conclude,which proves to be effective in practice.

Koji is the driving force,cellar is the basis,and the process operation is the key point.
