Drop forging is one of the common ways to manufacture a metal component. But what creats this method and why drop forgings so remarkably strong and tough? There are mainly two key aspects explaining why drop forging creates stronger products than other metal working processes and is an ideal manufacturing process for many critical metal components: predictable grain structure and uniformity.  
The raw material for forging is ingot. The defects of the foundry structure are mainly: the internal grains are coarse and nonuniform, the structure is loose and there are bubbles, shrinkage holes , micro-cracks, chemical composition segregation and nonuniform distribution of non-metallic impurities. The hot deformation process can greatly improve the cast structure,and the coarse columnar grains become a new equiaxed fine grain structure after plastic deformation and recrystallization; the defects such as looseness, voids and micro-cracks are compacted or welded with the three-direction compressive stress,the high melting point compound is distributed in a granular or chain shape along the direction of metal deformation after it was broken and the intergranular low melting point impurities are distributed in a strip shape along the deformation direction. As a result, the plasticity of the metal is increased and the mechanical properties are improved.
To achieve these properties of increased stregnth, resistance and toughness, alloy steel drop forging is typically done by heat treatment,also known as hot steel forging. Our company maintains an extensive inventory of alloy steel. Our most popular closed die alloy steels to forge include 20Cr, 20CrMo, 30CrMo, 35CrMo, 42CrMo, ect.
Alloy steel is also one of the most commonly used metals for drop forging. This is because drop forged alloy steel is known for being stronger, more wear resistant and tougher compared to carbon steel drop forgings. Alloy steel is considered to be iron-based alloys that has been alloyed or mixed with a variety of elements in the range of 1.00 – up to 50.0% to enhance the physical properties. The combination of alloys and elements forged together is what determines the phyical strengths and properties of the metal. Common alloys added are chromium, molybdenum, manganese, nickel, vanadium boron and silicon.

Hot forging, also called drop forging, is a process to produce a wide variety of most metal parts. Hot forging process is developed since the last century, but with the development of equipment, lubricants, and forging ability, modern hot forging process is able to make more complex shapes with more materials since that time. The basic procedure for hot forging is relatively simple. Metal bar or billet is first heated into the hot working temperature range to improve ductility. Then the material is squeezed or hammered in a series of tool steel dies to deform the billet into the finished shape. Flash casused by excess material after forging is exsited, so the final step is to remove the flash to yield the finished forged part. Hot forging is a near net shape process, but some forgings may require some subsequent machining, in particular for surfaces that may affect the final assembly of a product.

Aluminum forging is a process that involves shaping aluminum using compressive forces applied through dies or molds. The process is used to create a wide range of parts and components used in various industries, including aerospace, automotive, construction, and more. Aluminum forgings are valued for their high strength-to-weight ratio, corrosion resistance, and excellent thermal conductivity, making them ideal for use in many applications.

China Made Steel Pipes, Valves, Flanges & Pipe Fittings
Forged Ball Valves, Butterfly Valves Check Valves, Gate Valves, Globe Valves, Plug Valves,
Choose the appropriate tooth tip type according to the specific working conditions. For example, for working conditions with medium wear resistance and penetration requirements, you can choose a general-purpose tooth tip; for extreme conditions, you need to choose a reinforced or specially designed tooth tip.
All our teeth are using high spec alloy steels to ensure excellent wear characteristics, parts is checked by the original gages to make sure the fitting is standard and ease of installation wherever possible. Wide range, quality, service, we are your best choice.

In the process of forging, not only the appropriate shape and size must be required, but also the performance requirements of the parts during the use must be met, which includes strength index, plasticity index, impact toughness, fatigue strength, fracture toughness, resistance against stress corrosion and so on. This makes forging process always better than other metal working processes. Below we would like to introduce forging under different conditions.
