We concentrate on all kinds of metal casting for many years.

Die Casting

Die casting is a metal casting process, which is characterized by the use of mold cavity to melt metal to exert high pressure. Mold is usually made of high strength alloy, which is similar to injection molding. Most die castings do not contain iron, such as zinc, copper, aluminum, magnesium, lead, tin and tin alloys and their alloys. According to the type of castings, cold chamber die casting machine or hot chamber die casting machine should be adopted.

Gravity Die Casting

Gravity casting is the process of pouring molten metal into the mold under the action of gravity of the earth, also called casting. The generalized gravity casting include sand casting, metal mold casting, investment casting, die casting, mud casting; metal type casting refers to narrow gravity casting.

Investment Casting

Investment casting, also known as lost wax casting, includes wax pressure, wax repair, group tree, soaking, wax melting, casting metal liquid and post-processing technology. Wax casting wax was used to make castings, wax and wax were applied to the clay, and then coated with mud. The mud is dried, and the hot water is added to the internal melted wax. The melting end clay mold is dewaxing and baked into a ceramic mold. Roast it immediately. When making ordinary dies, leave the gate, and then pour molten metal from the gate. After cooling, the required parts are made.

Sand Casting

Sand casting, also known as sand mold casting, is a casting process with sand as the die material. The term “sand casting” can also refer to objects produced during sand casting. Sand castings are manufactured in specialized factories called foundries. More than 70% of the metal castings were produced by sand casting process.

Moulds made from sand are relatively inexpensive, and are also adequate refractories for the use of cast steel. In addition to sand, suitable binder (usually clay) is mixed with sand or occurs. The mixture is usually wetted with water, but sometimes wetted with other substances to develop strength and plasticity of clay and to make aggregates suitable for molding.

Heat treating
Metal heat treatment is one of the most important processes in mechanical manufacturing. Compared with other processing techniques, heat treatment generally does not change the shape of the workpiece and the chemical composition of the whole, but by changing the microstructure of the workpiece or changing the chemical composition of the workpiece surface, giving or improving the working performance of the workpiece. It is characterized by improving the internal quality of the workpiece, which is generally not visible to the naked eye.In order to make the metal workpieces have the required mechanical properties, physical properties and chemical properties, the heat treatment process is often necessary except for the reasonable selection of materials and various forming processes. Steel is the most widely used material in the machinery industry. The microstructure of iron and steel is complex and can be controlled by heat treatment. So the heat treatment of iron and steel is the main content of metal heat treatment. In addition, aluminum, copper, magnesium, titanium and other alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different performance.
