Foundry industry is a relatively intensive labor and resource industry, our country is rich in production resources, excess production capacity, labor costs have advantages.
铸造行业是一个劳动力、资源相对密集的产业，我国生产资源丰富，生产能力过剩，劳动力成本具有优势。
Foundry production is expanding and transferring from developed countries to developing countries.
铸造生产正在从发达国家向发展中国家扩展和转移。
China's entry into WTO has brought unprecedented development opportunities to the foundry industry.
我国加入WTO给铸造业带来了前所未有的发展机遇。
The production of modern machines has put forward more and more stringent requirements for the accuracy and overall quality of castings, which provides an opportunity for the vigorous development of investment casting and solid casting that can achieve precision casting production.
现代机器的生产，对铸件精度和整体质量提出了越来越严格的要求，这为能实现精密铸造生产的熔模铸造和实型铸造的大力发展提供了契机。
At present, there are two types of investment casting enterprises in China.
目前，我国熔模铸造存在两类工艺水平的企业。
One is the use of medium and high temperature mold, silica sol or ethyl silicate shell process, the production of aviation, gas turbine blades and stainless steel commercial precision casting factories;
一类是采用中、高温模料，硅溶胶或硅酸乙酯型壳工艺，生产航空、燃气轮叶片等和不锈钢商业精铸件的工厂；
The second is the use of low temperature mold, water glass shell process, the main production of carbon steel parts of the factory.
二类是采用低温模料、水玻璃型壳工艺，主要生产碳钢件的工厂。
A small number of factories, high level of technology;
一类工厂数量少，工艺水平高；
The number of second-class factories is large, and the production quality is low.
二类工厂数量多，生产质量低。
Modern investment casting is developing towards the direction of "precision, large scale and thin wall", and China's investment casting should conform to the development trend of The Times.
现代熔模铸造正朝着“精密、大型、薄壁”方向发展，我国熔模铸造应顺应时代发展潮流。
The first type of factory should keep up with international advanced technology and improve management
第一类工厂应紧跟国际先进技术， 改进管理
