1. Analysis of current situation of China's Metal Injection Molding industry
 
Metal Injection Molding is a process in which finished products and metal materials are produced by press forming, sintering and necessary subsequent treatment using various metal powders as raw materials. In the 1930s, the Metal Injection Molding process successfully produced porous oil-bearing bearings. With the use of cheap iron powder, the Metal Injection Molding process began to be applied in large scale in the automotive, textile and other industrial fields. In recent years, Metal Injection Molding has gradually become a processing method for manufacturing new materials.
 
The specific process of Metal Injection Molding is as follows: the first step is to prepare and prepare a raw material powder, which may be pure metal, non-metal, metal compound and other compounds; the second step is to press the powder into a desired shape according to the product design mold; It is sintered and formed. Metal Injection Molding has the advantages of energy saving and mass production of complex parts. The parts produced by Metal Injection Molding are close to the final size, once formed, with no or less cutting, so the material utilization rate is over 97%, and the machining material utilization rate is only about 50%. Since the Metal Injection Molding process eliminates multiple processes and the processing temperature is reduced, the mold can be quickly and repeatedly manufactured after molding, so that complicated structural parts can be mass-produced. Due to the various characteristics of Metal Injection Molding, it is especially suitable for a wide range of applications in the automotive and home appliance fields, and manufactures small-sized but complex components.
 
Metal Injection Molding is not only a promising component manufacturing process, but also a processing method for producing new materials. As a scalable technology, Metal Injection Molding continues to expand into other parts categories. First, Metal Injection Molding can make the core gear components of automotive engines and transmissions; it can manufacture parts for new energy vehicles, such as electric vehicle transmission systems, fuel cell connection plates, and so on. Secondly, Metal Injection Molding is a new material such as aluminum alloy, high alloy material, high temperature alloy, magnetic material manufacturing technology. For example, magnetic materials can be applied in new energy fields such as vehicle chargers, charging piles, photovoltaics, and solar energy. Metal Injection Molding is a general-purpose, platform-type technology, and its application range is gradually expanding, and the market prospect is broad.
 
2.The future development trend of China's Metal Injection Molding industry
 
Since the 1990s, the use of bicycles for Metal Injection Molding in the United States has increased significantly. In 1940, a large American automobile company changed all the oil pump gears used to Metal Injection Molding gears, and Metal Injection Molding structural parts began to be used in the automotive industry. Due to the increase in the quantity and weight of Metal Injection Molding parts used in American cars, from 1995 to 2005, the number of bicycle Metal Injection Molding used in the United States increased from 12.2 kg to 18.4 kg, an increase of 50%.
 
The reason for the increase in the consumption of Metal Injection Molding in the United States is mainly due to the expansion of the application range. The major growth in automotive Metal Injection Molding parts in the United States comes from the significant expansion of the range of applications for Metal Injection Molding parts. The Metal Injection Molding industry has developed from the production of iron-based bearings with only a few tens of grams of weight, transmission clutch plates, suspension ball joints and engine oil pump gears to technologies for producing highly complex special alloy parts, such as powder forged connecting rods and multi-seat transmissions. Brackets and engine VVTs, etc. In terms of products, the application of Metal Injection Molding parts to engines and automatic transmissions has increased significantly. 1) Due to the high cost performance of Metal Injection Molding parts, it can manufacture complex structural parts and provide reliable electrical pulses, which can be used to improve the electronic control of the engine.
 
Therefore, the use of Metal Injection Molding parts in the engine is significantly increased, and the Metal Injection Molding parts of each engine are increased by about 1.8-4.5Kg. 2) Due to the minimal subsequent machining required for the final forming of parts produced by Metal Injection Molding, the torque converter hub of the transmission, the transmission parking hub, the sprocket, the variable vane pump stator, the rotor, the body and the panel, etc. Most of them are converted into Metal Injection Molding, with an increase of about 2.8-8.2 Kg per gearbox Metal Injection Molding. From the experience of the United States, the trend of expanding the application of Metal Injection Molding parts on engines and gearboxes is also being interpreted in the Chinese market. China's automotive Metal Injection Molding parts market rose from 2.84 billion yuan in 2012 to 3.71 billion yuan in 2015, and the bicycle usage was about 3.9Kg. Considering the popularity of China's automotive Metal Injection Molding parts and the requirements for energy saving and emission reduction, the future use of bicycles will increase steadily. Corresponding to the development trend of the United States, the relevant components of China's powertrain also entered the process of accelerated penetration of Metal Injection Molding. Referring to the increase of Metal Injection Molding in the United States (the engine increased by 1.8-4.5Kg, the gearbox increased by 2.8-8.2Kg), the long-term Chinese Metal Injection Molding The bicycle usage will reach 9-16Kg. It is estimated that around 2025, China's Metal Injection Molding bicycles will reach 10Kg, calculated at 39,000 yuan per ton. The market size will reach 16 billion yuan, and the compound growth rate will be 17.5%.
