The pressure differential helps the metal flow into every intricacy of the mold. For the production of ceramic shells for the investment casting process a slurry is created from combining a liquid binder, refractory flours and sands.

Investment casting is most often used in the production of thin-walled odd-shaped castings bindeg in mechanical engineering and binder casting investment industry. This is one of the oldest casting methods for manufacture of statues, bells, cannons. A characteristic feature of this type of casting is that each pattern can be used for one casting only as it undergoes sweating in the course binder casting investment mold production, and the molding sand mixture itself is made not from a homogeneous molten metal, but from the refractory fine dusty material in the binder solution. It is the mixture design that contributes to obtaining castings with high surface quality. The precision of the pattern impress is provided by increased metal temperature, thus investment and binder materials should have a high fire resistance. The con of this method is a long and lengthy casting manufacturing process, which requires tailor-made expensive tooling and highly trained and qualified specialists.
Ultracast NSi is a highly stable binder with polymeric and biocidal additives made in Russia for the manufacture of ceramic molds in the manufacture of castings by investment casting, used as an alternative replacement of ethyl silicate binders. The suspension prepared with Ultracast NSi binders has stable rheological characteristics, a long «survivability» cycle and minimal requirements for keeping the suspension in working order. Increased resistance to cracking during the application of the refractory coating and removal of the wax model mass from the cladding is achieved due to the modified copolymer incorporated into the binder. Indicator name. Purpose and application of the Ultracast NSi binder Ultracast NSi is a highly stable binder with polymeric and biocidal additives made in Russia for the manufacture of ceramic molds in the manufacture of castings by investment casting, used as an alternative replacement of ethyl silicate binders. The advantages of the binder Ultracast NSi The suspension prepared with Ultracast NSi binders has stable rheological characteristics, a long «survivability» cycle and minimal requirements for keeping the suspension in working order. Ultracast NSi perfectly combined with the main types of refractory fillers.

Ultracast NSi perfectly combined with the main types of refractory fillers. Ultracast NSi — eco-friendly and industrially safe material In the manufacture of ceramic molds reduces the drying time of layers, compliance with the parameters of the microclimate of the site, the drying time of the layer can reach 1 hour.
When the first layer of the slurry is applied, it has an excellent wetting characteristic of the wax model, the suspension is applied evenly, excluding the formation of defects.
Technopark company has developed three modifications of binder Ultracast NSi : NSi—U applicable for use on the first layer high surface wettability, high resistance to cracking NSi is suitable for use on subsequent layers NSi-P «reinforced» binder is applicable for products with complex configuration, and large-size castings.

Water binder for investment casting
Remet have pioneered the binder casting investment from alcohol to water based binders within the investment casting industry, Enabling foundries to increase efficiencies, reduce costs, decrease environmental impact and improve the working environment, whilst improving binder casting investment quality of their investment castings. The technique can use substantially less material than gravity pouring because the sprue and some gating need not solidify. The earliest known text that describes the investment casting process Schedula Diversarum Artium was written around A. In these cases, we will consider a custom development project with our customers. Silica sol method costs more but has the better surface than the water glass method. Retrieved A view of the interior investment shows the smooth surface finish and high level of. This technique is more metal efficient than traditional pouring because less material solidifies in the gating. The investment shell for casting a turbocharger rotor.
