September 20, 2017, Beijing, Today, Guangxi Liugong Group Co., Ltd. ("Liugong") and Shougang Group Co., Ltd. ("Shougang") have signed a strategic cooperation agreement at BICES 2017. This strategic cooperation agreement will be furthered. Promote comprehensive and in-depth cooperation between Liugong and Shougang in the steel business, mining machinery, engineering machinery, and construction machinery. It is reported that Liugong acquired a 42% stake in Beijing Shougang Heavy-Duty Vehicle Manufacturing Co., Ltd. in 2011 and became a shareholder of Shougang CNPC with Shougang Mining Co., Ltd. and began to establish a cooperative relationship with Shougang. Although facing the decline of the mining market in the past six years, both parties are still sincerely cooperating to overcome the difficulties and jointly support the development of Shougang. In June 2017, Liugong further acquired the equity of Shougang Steel and became the controlling shareholder of Shougang CNPC. Liugong continues to promote the development of mining truck products and business. After six years of cooperation, the two sides mutually recognized each other's corporate culture and values, and both have the intention to further strengthen cooperation. Therefore, this time the company further signed a strategic cooperation agreement. In the signing of the strategic cooperation agreement, Liugong and Shougang established the long-term strategic cooperation relationship of the mining machinery industry based on the principle of complementary advantages and win-win cooperation, and further developed the strategic cooperation relationship in steel business, engineering machinery, and construction machinery. The two sides will establish a system of regular meetings between senior leaders and set up a joint special working group to promote the implementation of strategic cooperation between the two sides.

Food machinery precision casting or food machinery investment casting, silica sol process. It is a casting process with little or no cutting.
Cast food machinery is an excellent process technology in the foundry industry. Its application is very extensive. Food machinery cast not only applies to the casting of various types and alloys, but also produces the dimensional accuracy of castings. The surface quality is higher than that of other casting methods, and even castings that are difficult to cast and which are difficult to cast have high temperature resistance and are not easily processed can be cast using investment casting.
In wax pattern process,we mix stearic acid and paraffin wax in wax pattern making,as you know,it is better than polyethylene,and the wax deformation is small.
In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at 24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.
In shell hardening process,we use aluminium chloride to harden the shell.This can make the shell so hard that it can`t be distorted,at the same time the bug which the casting may have will be decreased.If there are letters or numbers in it,they will be much clearer.
In dewaxing process,about 95% of the castings suppliers adopt the original water dewaxing technics,but we using the advanced steam dewaxing technics,which we are very proud of. This can effectively avoid the air-hole and sand-hole, making the casting look much nicer.
In smelt process, we use middle frequency furnace, avoiding the emergence of the oxide; in molten steel control part, we use Germany-imported direct reading spectrometer machine, assuring its quality before the molten steel out of the furnace. During this process we use ERP production and management software to get the feedback information.
In shell-knock out process, we have special machines,which can decrease the hitting and knocking, easily made by manual shell knocking out.
In shot-blasting process, we have crawler-type and hanging shot-blasting machine, with steel shot 0.5-0.8, making the products smooth.Of course, if the customer wants it look much nicer, we also can carry out sand-blast treatment.
In heat treatment process, we use electric furnace, and adopt double-temperature control in order to heat the products equally. As a result, the products will have great metallurgical structure.
Our tolerance can reach at the grade of 5-7 according to our country`s tolerance standard.
In machining process,we have 12 CNC machining centers and some other machines, so we can make further machining if the customers need.
