Domestic high-end foundry companies started independent research and development

As the market's demand for precision foundry products has increased, related companies in China have begun to move away from the constraints of foreign products and began to move toward independent development and provide product market competitiveness.

Casting molds refer to the models used to obtain qualified parts, common hand moldings, commonly used wood models, plastic models, and multi-purpose metal models for mechanical modeling, such as aluminum models and iron models. A wax model for precision casting and a polystyrene model for lost foam. Casting mold means that in order to obtain the structural shape of the part, the shape of the part is formed in advance with other easily-formable materials, and then the mold is placed in the sand mold, so that a cavity having the same size as the part structure is formed in the sand mold. In the cavity, a liquid is poured again, and after the liquid is cooled and solidified, parts identical to the shape of the mold can be formed.

Independent research and development has become the primary goal of the development of domestic foundry enterprises. Luo Baihui, secretary-general of the International Model Association, stated that it is fundamentally independent only if it is completely separated from technology. In order to get rid of this long-term dependence, domestic sector foundry companies have started to gain market access through independent development. Recently, the non-ferrous metal casting factory in Xiangtang Town, Xiangcheng District, Suzhou City, through a self-developed tooling mold, has embarked on a transformation path for precision casting.

It is reported that the precision casting company currently has a total of 118 personnel and produces more than 800 kinds of non-ferrous metal parts. Although other companies in the past two years have experienced major ups and downs in export-oriented nonferrous metal casting business under the financial crisis. However, Xiangcheng Non-Ferrous Metal Casting Factory has not been “anxious” for this purpose, but thinks this is a good time to adjust the product structure. In order to fully meet the needs of customers, it has begun to independently develop and process molds. Increased market development efforts and achieved intensive development in line with the international market.

At present, in order to shorten the molding cycle and increase the market competitiveness, casting mould companies adopt more and more high-speed cutting technology. HSM is generally used for large and medium-sized mold processing, such as car cover molds, die-casting molds, large plastic molds and other curved surface processing, the curved surface processing accuracy of up to 0.01mm. In the production of CNC high-speed milling technology, can greatly shorten the time of the mold. After high-speed milling, the mold surface after finishing can be used with only a little polishing, which saves a lot of grinding and polishing time. The increase of CNC high-speed milling machines is one of the key investments for mold and equipment enterprises.
