HMAX series mold steel for hot forging mold steel: HMAX-D\HMAX-R\HMAX-3\HMAX-4\HMAX-5\HMAX-6.HMAX new high red hardness, high strength, toughness and high wear resistance mold series, among which HMAX- 3 Mold steel is one of the HMAX mold steel series. It has a pure matrix and uniform structure. It is a high-performance chromium-molybdenum-vanadium alloy steel with good resistance to thermal cracking, cracking, thermal wear and plastic deformation. It has the following characteristics: excellent toughness and ductility in all directions, good tempering resistance, good high temperature strength, excellent hardenability, heat treatment, and good dimensional stability after surface coating.

According to the forging temperature, it can be divided into hot forging, warm forging and cold forging. The starting recrystallization temperature of steel is about 727°C, but 800°C is generally used as the dividing line. Above 800°C is hot forging; between 300 and 800°C is called warm forging or semi-hot forging, and forging is performed at room temperature. is called cold forging. Forgings used in most industries are hot forgings. Warm forging and cold forging are mainly used for forging parts such as automobiles and general machinery. Warm forging and cold forging can effectively save materials.

Casting can also be divided into gravity casting and pressure casting according to the pouring process of molten metal. Gravity casting refers to the process in which molten metal is poured into a mold under the influence of the earth's gravity, also called casting. Gravity casting in a broad sense includes sand casting, metal mold casting, investment casting, mud mold casting, etc. Gravity casting in a narrow sense refers specifically to metal mold casting. Pressure casting refers to a process in which molten metal is injected into a mold under the action of other external forces (excluding gravity). Pressure casting in a broad sense includes pressure casting and vacuum casting of die-casting machines, low-pressure casting, centrifugal casting, etc. Pressure casting in a narrow sense specifically refers to metal mold pressure casting of die-casting machines, referred to as die-casting. These casting processes are currently the most commonly used in non-ferrous metal casting and are also the cheapest.

What are the characteristics of aluminum alloy die-casting products?

There are four types of aluminum-silicon series (AL-Si), aluminum-copper series (Al-Cu), aluminum-magnesium series (Al-Mg) and aluminum-zinc series (Al-Zn). Commonly used grades include ADC12 (A383), ADC10 (A380)

Die-cast alloys are divided into two categories: cast steel alloy materials and non-ferrous metal alloys. Cast steel alloys are not commonly produced in China due to problems such as high melting points, easy oxidation, molds, and low service life. Non-ferrous alloys include low melting point lead alloys, Tin alloy, zinc alloy, high melting point aluminum alloy, magnesium alloy, copper alloy, etc. Among them, aluminum alloys are relatively more widely used, and magnesium alloys have been increasingly used this year.
