    Cast Iron Metal

    Cast iron, also known as cast iron, is made by adding other metal elements, scrap steel, and recycled iron during the smelting process to adjust its composition and change its internal structure through forging, deterioration, spheroidization, and other methods. The carbon content of cast iron is above 2.11%. Industrial cast iron generally has 2.5% to 3.5% carbon content. In addition to carbon, cast iron also contains 1% to 3% silicon, manganese, phosphorus, sulfur, and other elements. The form of carbon in cast iron makes cast iron have unique properties. One of the classifications of cast iron we will talk about below is based on the form of carbon in the iron. Cast iron is primarily produced using casting processes to create iron castings with special shapes and properties.

    Metal Stamping

    Metal stamping is a metal fabrication process. It is a forming processing method in which we use presses and molds to apply external forces to sheets, strips, pipes, and profiles to cause plastic deformation or separation and to obtain metal stamping parts of the desired shape and size. Both metal stamping and forging belong to plastic processing (also called pressure processing), collectively called forging. The blanks for metal stamping are mainly hot-rolled and cold-rolled steel sheets and strips.

    Hot Forging

    Hot forging is one of the metal manufacturing processes to heat the metal billet above its recrystallization temperature using heat conduction heating, electromagnetic induction heating, or electric heating, and then forge so that the billet undergoes plastic deformation to make forgings with specific shapes, sizes, and mechanical properties. Hot forging is a necessary process, and hot forgings are widely used. The hot forging process can process a lot of metals and has irreplaceable advantages.

    Lost Wax Casting

    Lost wax casting is also known as investment casting. It has the process for Wax Pressing, Wax Repairing, Tree Formation, Dipping, Melting Wax, Casting Molten Metal, and Post-processing. Lost Wax Casting is the process that uses wax to make a wax mold according to the part to be cast and then coating the wax mold with mud, which is the mud mold. After the clay mold dries, it is placed in hot water to melt the inner wax mold. And then, take out the clay mold that has melted the wax mold and bake it into a pottery mold. Generally, when making the mud mold, the sprue is left. Pour the molten metal into the sprue. After the mold is cooling, we can get the lost wax casting parts.

    Lost Foam Casting

    Lost foam casting (solid mold casting) is a new and widely used precision casting process. Its process is as follows: use paraffin or foam to make a model according to the size and shape of the casting and bond and combine it into a model cluster; after the surface of the casting cluster is brushed with refractory paint and dried, the model is buried in dry quartz sand and vibrated Modeling; complete pouring in a negative pressure situation, high temperature vaporizes the model, and the liquid metal occupies the position of the model; after cooling and solidification, get castings. Lost Foam Casting is a new technology with nearly no allowance and precise forming. It does not need to close the box to take the mold. It uses dry sand molding without a binder, which reduces pollution. It is known as the most likely process technology to achieve green casting in the 21st century.

    Aluminum Die Castings

    Aluminum die castings mean the parts made of pure aluminum or aluminum alloys obtained by die casting. Generally, aluminum or aluminum alloys heated to a liquid state are pressed into a metal cavity by a die casting machine, and aluminum parts or aluminum alloy parts of various shapes and sizes are obtained after cooling. These parts are usually called aluminum die castings.
