The spray-casting production method is characterized in that the molten metal liquid is sprayed into fine particles (10-500 micrometers) via an atomizing device in a very short time, and the sprayed metal is deposited on a predetermined deposition plate.
The big feature of the injection molding process is the rapid cooling, solidification and atomization of the molten metal, which enables the supersaturated second phase in the molten metal to be refined and evenly dispersed, which overcomes the slow cooling rate in the traditional casting process. The resulting macro segregation and organizational coarseness. The injection molding process is directly formed from a molten metal into a solid body, which also overcomes the problems of cumbersome and multi-pass treatment procedures, poor organization density, and severe powder oxidation during the powder metallurgy process, resulting in a higher ratio of injection molding materials. Powder metallurgy materials have low porosity and good properties.
The advantages of injection molding are many, such as: high stacking rate, (usually 0.25 - 1.7 kg/s); shape can be complex, can reduce the processing process; alloys are diversified, components are not limited; coarse embryos The density of the body is higher than that of powder metallurgy, and the oxide content is also small.
In the injection molding process, the molten metal can be rapidly cooled, solidified and solidified into a solid shape, which overcomes the problems of macro-segregation in the conventional casting process and oxidation in the powder metallurgy process, and exhibits excellent material properties.
The injection molding process method is a new type of aluminum alloy molding method, which is a choice of building materials, automotive parts, and composite materials used in nuclear power plants.
The Morse taper shank Drill Bit is a self-locking (or self holding) taper of approximately 5/8" per foot that allows the torque to be transferred to the drill bit by the friction between the taper shank and the socket. The tang at the end of the taper is only for ejecting the drill bit from the spindle, with the aid of a drift.
The arbor of a drill chuck is often a Morse taper and this allows the chuck assembly to be removed and directly replaced with the shank of a Morse taper drill bit.
Its material is high speed steel,treatment process is roll-forged
