Power transmission castings are main products in our water glass casting plant.

We are proud to serve the power transmission industry in many areas, producing castings that must pass stringent requirements used in high voltage sub-station power switching and storage equipment. 

With a long history of innovation, we has created comprehensive solutions for the power transmission industry to improve reliability in sometimes adverse environments in order to meet grid requirements and prevent power outages. 

The demand for quality power transmission systems has never been greater. Contact us to learn how we can help with electrical, wind, or solar power transmission casting requirements. We look forward to working with you.

Water Glass Casting

Water glass casting is one of the most common investment casting processes in China, but is seldom in other countries. In Chinese investment casting foundries, about 80% foundries focus its business in water glass casting, while the rest are silica sol casting factories. So what is water glass casting?

Water glass casting, one kind of lost wax investment casting process, uses water glass as the binder for the shell. The origin of water glass casting is in Russia. Process of water glass casting is what we described in investment casting process, with this method, it is suitable for steel castings, especially for carbon steel and alloy steel castings. It allows to produce steel castings ranging from 0.5kg-60kg.

Why Water Glass Casting?

Water glass casting process was introduced to our country in the mid of 1950 by the former Soviet union, it is different from the ethyl silicate binder investment casting process. Due to the advantages of material cost and production cycle, water glass casting was quickly applied in civil machinery manufacturing. With the development of water glass casting process in our country for more than 60 years, in terms of its production scale and application field, it has become the mainstream of investment casting industry of China.

By adding 0.5% penetrant, the surface quality of water glass casting is greatly improved, and surface finish can even be comparable to the silica sol casting technology. It can avoid defects caused by traditional shell making technology. At the same time, the working environment is improved obviously. In addition, the process parameters and operation requirements are not so complicated and strict, general workers are available to operate shortly. This reduced the loss of skilled workers and new workers are also feasible, which stabilized the normal production efficiency of the factory. In terms of costs, shell making material cost of water glass casting is not added compared with traditional hardening process, and this process decreased the weld repair processing significantly, improve the product rate shortens, and thus to reduces the production cost and the production efficiency.
