An effective method to prevent sand inclusion in stainless steel castings

The sand in the sand mold is not clean and there is residual sand and gravel, which is caused by the molten iron washing the sand on the sprue wall during the pouring process. Some use paint to prevent, get a better effect, but there will be castings appear sand, because the gate paint is more hard and difficult.

Five ways to prevent locking of stainless steel fasteners

A type of mechanical parts that are used for fastening connections and are widely used. In all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies, etc., you can see a variety of fasteners. It is characterized by a wide variety of specifications, different performance uses, and standardization, serialization, generalization of the species is also very high. Therefore, some people have also referred to a type of standard fasteners as standard fasteners, or referred to as standard parts.

Investment casting

Lost wax casting is now called investment precision casting, is a kind of less cutting or no cutting casting process, is an excellent process technology in the casting industry, its application is very extensive. It is not only suitable for casting of various types and alloys, but also produces castings with high dimensional accuracy and surface quality than other casting methods. Even castings that are difficult to be cast by other casting methods are complex, high temperature resistant and not easy to process can be cast by investment precision casting.

What is casting? The development of casting?

Casting is a process in which the metal is melted into a liquid that meets certain requirements and poured into the mold. After cooling, solidification and cleaning, the process of obtaining a casting with a predetermined shape, size and performance is obtained. The casting blank is nearly shaped, and achieves the purpose of no machining or a small amount of machining, which reduces the cost and reduces the time to a certain extent. Casting is one of the basic processes of modern manufacturing industry.

Describe in detail the characteristics and differences of various castings

Casting can also be divided into gravity casting and pressure casting according to the pouring process of liquid metal. Gravity casting refers to the process of injecting liquid metal into the mold under the action of the earth's gravity, also known as casting. Generalized gravity casting including sand casting, metal casting, investment casting, clay casting; narrow meaning of gravity casting refers specifically to metal casting. Pressure casting refers to the process of injecting liquid metal into the mold under the action of other external forces (without gravity). Generalized pressure casting including die casting machine pressure casting and vacuum casting, low pressure casting, centrifugal casting, etc.; narrow sense of pressure casting refers specifically to the metal die casting machine pressure casting, referred to as die casting. Xudong Precision Casting Factory has long been engaged in gravity casting of sand molds and metal molds. These casting processes are the most commonly used in non-ferrous metal casting and the lowest relative price.

Development Prospect of Precision Casting

Investment mold precision casting refers to the meltable model made of fusible materials, coated with several layers of special refractory coatings, dried and hardened to form a whole shell, then melted the model from the shell with steam or hot water, then placed the shell in a sand box, filled with dry sand around it for modeling, and finally put the mold into a baking furnace for high-temperature roasting. After the mold or shell is roasted, A molten metal is poured therein to obtain a casting.
