Industrial Mold

  The density ratio between aluminum and steel is 1:3, and aluminum die instead of steel die can save 1/2 in quality. The steel - aluminum compound die was used. The cost of the aluminum alloy die is about 15% lower than that of the steel mold.
The production time of the aluminum die is much shorter than that of the steel die, so the time occupied by the fund is less and the advantage is obvious.
The cutting cost of the aluminum die is 35% lower than that of the steel die. It can be completely processed as follows: repair welding (repair and correction welding), the milling time of the surface hardening treatment (anodizing, electroless plating and nickel plating) is 5~10 times longer than the aluminum die, 5 times the length of the drilling time, 4 times the machining time of EDM, and the polishing time. The life span of cutting tools is 3~4 times longer than that of cutting steel dies by 4 times.
Using aluminum steel compound die can greatly shorten processing time and save processing cost.
Typical alloys are 2024, 5052, 5754, 5056, 6061, 7075 and so on.
Product features: high strength and excellent machinability.

 Beryllium copper, a copper based alloy with supersaturated solid solution, is a nonferrous alloy with mechanical properties, physical properties, chemical properties and corrosion resistance. After solid solution and aging treatment, it has a high strength limit, elastic limit, yield limit and fatigue limit, which is equivalent to that of special steel. At the same time, it has high conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance. It is widely used in the manufacture of various mold inserts, replacing steel with high precision, complex shape, welding electrode material die-casting machine, injection molding machine punch, abrasion resistance and corrosion resistance. The beryllium copper belt is applied to micro electro mechanical and electrical brush, cell phone battery,
Computer connectors, various kinds of switch contacts, springs, clamps, washers, diaphragms, film and other products. It is an indispensable and important industrial material in the national economic construction.

The titanium alloy has stable microstructure, good oxidation resistance and weldability, and the corrosion resistant machinability is better, but the plasticity is low (thermal plasticity is still good), and the stamping performance at room temperature is poor. The most widely used one is TA7, which has moderate strength and sufficient plasticity and good weldability in annealed condition. It can be used below 500 C. When the impurity elements (oxygen, hydrogen, nitrogen and so on) in the gap are very low temperature, they have good toughness and comprehensive mechanical properties. It is one of the excellent ultra-low temperature alloys. The structure and various die forgings used for long-term work below 500 degrees, such as: making engine compressor plates and blades.

 ɑ+β type titanium alloy has good comprehensive mechanical properties, most of which can be heat treated and strengthened (but TC1/TC2/TC7 can not be heat treated and strengthened), forging, stamping and welding performance are good, machinable processing; room temperature strength is high, 150~ Below 500 °C and better heat resistance, some (such as TC1/TC2/TC3/TC4) and good low temperature toughness and good resistance to seawater stress corrosion and resistance to hot salt stress corrosion, the disadvantage is that the organization is not stable enough . Stampings, weldments, die forgings and various parts for bending work below 400 °C. Long-term working parts below 400 °C, structural forgings, various containers, low temperature parts, tank tracks, etc.

 Magnesium-zinc-zirconium-based magnesium alloy: It has high strength and good plasticity and corrosion resistance. It is one of the most widely used wrought magnesium alloys, with no stress corrosion cracking tendency, simple heat treatment process and good machinability. It can produce large forgings with complex shapes, but the welding performance is unqualified.

 Magnesium-aluminum-zinc-based magnesium alloy has the following properties: 1. High strength and heat treatment strengthening. 2. Casting performance is good. 3. The corrosion resistance is poor. The stress corrosion cracking tendency of MB2 and MB3 alloys is small, and the stress corrosion cracking tendency of MB5, MB6 and MB7 alloys is large. 4. Good machinability. 5. The thermoplastic is preferably MB2 and MB3 alloy, which can be processed into various magnesium materials such as plates, bars and forgings; MB6 and MB7 alloys have lower thermoplasticity and are mainly used as extrusion parts and forgings. 6. MB2, MB3 alloy has good weldability, gas welding and argon arc welding. The weldability of MB5 alloy is poor. The weldability of MB7 alloy is still good, but stress relief annealing is required.
The main uses are:
Used for making complex forgings, die forgings and medium load mechanical parts for aircraft interior components, siding
Mainly used to make parts that withstand large loads
Mainly used to make parts that withstand large loads
Can be used in place of MB6, used as a variety of structural parts to withstand high loads.
