to undertake more than 350 Jiahe County in Guangdong Industrial and Foundry to return home to accommodate the expansion of local foundry business development, Jiahe County Industrial Park in the Tan Tong Industrial Park, located in the casting, while the first phase of the planning longtanzhen 600 acres of land for the Foundry Association business base, more than 20 million Loaning longtanzhen has started construction of the base. The base will become the Yuan town, Tan Tong Industrial Park after another foundry industry gathering. "Golden Harvest manufacturing" industry leader in metal casting low-carbon development, according to Luo Hui, in recent years, the county's casting forging industry is developing rapidly, "Golden Harvest create" hardware machinery products all over the north and south.

However, due to firm size, technological level there is uneven, a few high energy consumption, high pollution discharge enterprises also increased pressure on the county's industrial energy conservation. To promote the traditional industries of energy conservation, low carbon industry to guide the direction of the county's accountability and the implementation of energy saving vote veto system, give prominence to the key enterprises casting forging energy conservation. Strict implementation of the project review system and access to joint projects, "three simultaneous" system, improve project access "threshold."

Since September 2009, the county has banned include shutting down the upper reaches of a small smelting casting forging companies, including more than 100, to promote the use of new energy saving technologies, new products, new materials, to promote the unit GDP energy consumption decline. The county through the implementation of differential pricing, industry focus to guide the implementation of energy saving capital transformation of the tilt casting forging companies to encourage enterprises to save energy policy. Shonan Casting Co., Ltd is the New Tan Tong Industrial Park, a machine foundry business, this company invested 20 million yuan, in the county's support, introduced on behalf of today's most advanced foundry industry lost foam molding process.

Lost foam molding process and the traditional molding process compared with the labor-intensity, high efficiency and low pollution, low-emission benefits, and produced castings with a smooth, non-porous characteristics, the price per ton than the traditional style casting can be nearly thousand dollars. Technology upgrade, the company has produced a variety of precision casting conditions, the current business owners are aiming to develop wind Hunan is the development of helicopter transmissions and other high-end equipment and machinery castings. According to statistics, first quarter of 2010, the county completed GDP14.42 billion yuan, up 24.8%, chemical oxygen demand reduction the county completed 100 tons yuan industrial added value 13.4% reduction in energy consumption.

CNC Machine Tool force extension casting chain March 22, 2011, from Jiahe County Zhuquan Economic Development Zone has learned that casting for the expansion of the industrial chain, the county has introduced a giant, big love, Hunan number and a number of CNC machine tools manufacturing, CNC machine tools to further enhance the county's manufacturing capacity, to promote Golden Harvest casting to the "Golden Harvest made" transformation has taken a welcome step beyond.
