A melting process of physical and chemical phenomena Alloy melting is an important part of the die-casting process; the melting process is not only to get molten metal liquid but, more importantly, to get the chemical composition in line with the regulations; it can make
Polishing is a processing method that uses mechanical, chemical or electrochemical action to reduce the surface roughness of a workpiece to obtain a bright, flat surface. It finishes the workpiece surface using polishing tools and abrasive particles or other polishing media. Polishing methods and processes
Definition of sandblasting, shot blasting, and shot peening Sandblasting Sandblasting is the use of compressed air as the power to form a high-speed jet beam to spray material (copper ore, quartz sand, diamond sand, iron sand, Hainan sand) high-speed spray to the surface of the
Surface treatment: A protective layer can be formed on the product’s surface to protect the body after treatment by mechanical and chemical methods. It can achieve a stable state in nature, increase the body’s corrosion resistance and increase the product’s beauty, thus enhancing its value. The
Semi-solid die-casting technology refers to the process of solidification of aluminium alloy from liquid to the solid state; when the temperature drops between the liquid and solid phase lines (solid-liquid two-phase zone), the microstructure of the aluminium alloy is made to be a liquid phase
Red is the special material for aluminium alloy die casting die, and yellow is the special material for copper alloy die casting die. DH31S Datong Hot working steel Characteristics of die steel: Japan Datong special steel patent steel, high life hot work die steel, small
Type and characteristics of die casting machine Classification of die-casting machine Die casting machines are usually divided into hot chamber die casting machines and cold chamber dies casting machines according to the working state of their pressure chamber. The pressure chamber of the hot chamber
When selecting die-casting materials, product design engineers should choose the correct materials according to various factors such as the product’s service performance, process performance, production conditions, economy and the characteristics of die-casting materials. The commonly used die-casting materials include aluminium, zinc, and magnesium alloy. Aluminum
1.Weight difference: the proportion of cast aluminum is lighter than cast iron, the density of cast iron is about 7.8g /cm3, and the density of cast aluminum is about 2.7g /cm3. The same size as cast iron and cast aluminum, the latter’s weight is lighter.
