A private modern enterprise specializing in scientific research, production and large-scale mechanical processing of ductile iron, vermicular graphite cast iron, gray cast iron and special performance cast iron.

Guangdong Zhongtian Chuangzhan Ductile Iron Co., Ltd. is located in Yingde City, Qingyuan, Guangdong Province. It is a private modern enterprise specializing in scientific research, production and large-scale mechanical processing of ductile iron, vermicular graphite cast iron, gray cast iron and special performance cast iron. It is the largest enterprise producing similar products in Guangdong Province, and has been recognized as a national high-tech enterprise, a national intellectual property advantage enterprise, a specialized new small and innovative enterprise in Guangdong Province.

The company was founded in 1980, formerly known as Dadu Casting and Forging Factory. In 2000, it acquired the original Huadu Ductile Iron Factory and changed its name to Zhongtian Chuangzhan Ductile Iron Co., Ltd., Shunde District, Foshan City, and carried out a comprehensive technical transformation, built a new factory building, and purchased advanced production and Testing equipment has expanded the company's production scale and greatly increased its production capacity. In December 2010, taking the opportunity of Qingyuan (Yingde) Economic Cooperation Zone in Shunde, Guangdong Province, industrial upgrading and transformation were carried out, and a larger and more modern production base-Guangdong Zhongtian Chuangzhan Ductile Iron Co., Ltd. was officially built in the scenic Yinghong Industrial Park. The company covers an area of 300000 square meters and a plant area of 150000 square meters. It has undertaken all the casting technology, research results, key research equipment, capital and patent technology transfer of Shunde Zhongtian.

The products are all made of furan resin sand and produced by intermediate frequency induction furnace, with an annual production capacity of 100,000 tons. The single piece of ductile iron castings weighs up to 70t and the single piece of gray iron castings weighs up to 80t, which is in the leading level in the province. The main products include: ductile iron castings, vermicular cast iron, gray cast iron and special performance cast iron and other cast iron scientific research, production and large mechanical parts precision machining, etc.,

The main supporting production industries are: construction machinery, die-casting machinery, injection molding machinery, automobile extrusion molds, wind power generation machinery, aluminum alloy wheels, including film machinery, pressure machinery, medical machinery, petroleum Machinery, valves, spark machinery, etc., are also exported to Geman, France, the United States, Japan,South Korea, Chinese Taiwan, Chinese Hong Kong and other countries and regions, and get a good reputation.

Quality is the life engineering of an enterprise, and the company has a perfect quality management system and excellent quality management personnel. In November 2014, the ISO9001 was fully introduced and implemented: 2008 the quality management system to continuously improve product quality; The engineering center laboratory and pre-furnace testing enable the company to completely control the quality of the whole process from raw and auxiliary materials, intermediate production to final products.

At present, as a group of senior middle and senior technicians and managers, the company keep improving in research, especially in the fields of high toughness and low temperature impact ductile iron, large section ductile iron production technology, high wear resistance cast ductile iron, high strength and low stress machine tool castings and metal matrix composite materials, and has achieved remarkable results, it is the main revision unit of the national standard "ductile iron castings" GB/T 1348-2019 and the participating revision unit of "ductile iron metallographic examination" GB/T 9441-2009. It has obtained 11 authorized invention patents, 26 utility model patents and 2 appearance patents. So far, it has passed the identification of 12 high-tech products and 2 famous high-tech products. The company has innovative research platforms such as Guangdong Engineering Technology Research Center, Guangdong Provincial Enterprise Technology Center, Qingyuan Engineering Technology Research Center and Qingyuan Science and Technology Commissioner Workstation; the company is the director of China Foundry Association, the director of Foundry Society of China Mechanical Engineering Society, the fourth president unit and the fifth vice president unit of Guangdong Foundry Industry Association, and the vice president unit of casting and die casting branch of Guangdong Mechanical Engineering Society.

Analysis to liquid metal flow

This animation represents the charge Filling process and this process Medium metal liquid temperature change the situation. Total filling type The time is 100 seconds. The liquid metal rises casting 2/3, hot Liquid metal injection at riser Into the cavity, thus creating The temperature of this part is relatively high. High Fill to casting When in the middle, due to the liquid Surface rise speed relative Slower, cold iron contact The local temperature of the part is reduced.
