Foundry The Prospect Of Development

Wuxi Hoohi Engineering Co.,Ltd | Updated: May 10, 2017

Foundry precision casting materials

Foundry metal materials mainly from the outsourcing of materials, the enterprise's waste castings, pouring risers. The outsourcing of metal materials is often in bulk, very few pressed into a tube, different materials are easy to confuse together, such as 316 material mixed with 304 or 430 material. Therefore, the precision casting enterprises to choose as much as possible to purchase into a cylindrical material. The chemical composition of each batch of purchased material was analyzed using a spectral analyzer. If possible, the supplier should conduct field visits to evaluate whether the material is to be identified, protected and isolated.

Foundry For the enterprise scrap (waste castings, pouring risers) to be in addition to corrosion, to oil, sand and clean and dry treatment, control S, P ingredients. And, the scrap of different materials to be identified, protected, separated storage, can not be confused.

Foundry tells you the prospect of precision casting development

Investment Casting is a fusible material made of fusible material, on which a number of layers of special refractory coating, after drying and hardening to form a whole shell, and then steam or hot water from the shell Melt the model, and then put the shell in the sand box, filled with dry sand in its surrounding shape, and finally the mold into the roasting furnace after high temperature roasting, casting or shell by roasting, pour molten metal in which Get cast.

The precision welding of the products obtained by precision casting is very close to the final shape of the parts, which can be used without processing or very little processing. It is an advanced process of near net forming. It is an excellent process technology in the casting industry. Application is very extensive. It is not only suitable for all types of casting of various alloys, but also to produce the casting size accuracy, surface quality than other casting methods to be high, and even other casting methods difficult to cast the complex, high temperature, easy to process castings, Can be used to melt casting precision casting.

Foundry At present, the world's investment casting process has developed rapidly and widely used. From the current situation, the future development trend of the process is that the casting products are getting closer to the parts and components. The traditional casting is only blank, Market quick response. The complexity of parts and components and the quality of the increasingly high grade, research and development means more and more strong, professional collaboration began to show, CAD, CAM, CAE application of parts and components to become the main technology.

From the current development situation analysis, investment casting technology is very wide range of applications, the future development prospects of the future want to be broad.
