Demand for powder metallurgy parts remains stable growth

In the past 10 years, from the market demand for auto parts, from 34% to 45% growth. And, in recent years, the demand for powder metallurgy parts in the automotive industry is still growing steadily. A car in the weight of powder metallurgy parts, the United States increased from 12 kg to 18-20 kg, Japan rose from 6.5 kg to 10 kg, from 7 kg to 8-10 kg in europe.

Large orders, high profits, become the supplier of auto parts, is the development goals of many powder metallurgy enterprises. However, the strict requirements on the quality of automotive parts, discourage  many enterprises.

As with the host plant plans to maintain coordination, to meet the needs of the host plant frequent changes: "on time delivery" supply mode; to ensure quality and stability, the whole process of quality tracking, etc.. Faced with changes in market demand, how to overcome the difficulties, seize the opportunity, every day thinking about the problem of powder metallurgy entrepreneurs. "The devil in the details", from the powder metallurgical material and mixed material screening, forming, sintering and post processing, On a step by step, resulting in thousands of miles.

The 21st century, the rapid development of science and technology for powder metallurgy products of China's rapid development provides a solid foundation, powder metallurgy products in China from so far only lasts for a few decades of time has in the market into the from all walks of life, which indicates that the powder metallurgy products in today's society has great significance.

Powder injection molding is widely used in the field of mobile phone

The application of powder injection molding is more and more extensive, and the technology of powder injection molding is used on the mobile phone. As the market needs a lighter, thinner and more beautiful cell phone, the best technology to reduce the size of the phone, mobile phone companies are seeking to use metal injection molding method to manufacture mobile phone assembly parts.

Our first metal cell phone is made of aluminum, we found that in order to meet all the requirements, metal injection molding method is the best, in many cases is the only choice. But not as the first material parts, metal injection molding, because the mobile phone market has very short service life, the style changes quickly, and the metal injection molding method of long production cycle, high cost.

Now there are several mobile phone parts are made of metal injection molding manufacturing method, such as: the use of tungsten manufacturing oscillator balance weight, using high strength steel hinge manufacture, application of metal injection molding is the most important method in mobile phone manufacturing slide, barrel and hinge. Technical advantages and metal injection molding method of metal injection molding can increase its application in mobile phone manufacturing, mobile phone manufacturing industry of metal injection molding method is lack of understanding of the impact of the application.

Now the metal injection molding method is used to create the structure and function of complex mobile phone, such as flip mobile phone. Considering the time and cost of manufacture, making the ordinary mobile phone should not be used for metal injection molding parts.

From this event can be seen, the application of powder injection moulding to more widely. The technology is more and more skilled, with the development of social economy, the powder injection molding will step onto a higher level.

Domestic metal injection molding industry product quantity and output value has a lot of room for improvement

At present, the competition between countries in the automotive industry is becoming increasingly fierce, the prerequisite for winning in the fierce competition is the low cost technology to produce high quality products, the automobile industry in the near net forming processing production put forward higher requirements. The development of metal powder injection molding (MIM) technology has greatly promoted the development of automobile industry.          

MIM combines the advantages of two kinds of powder metallurgy and plastic injection molding technology, breaking the traditional metal powder pressing molding process in product shape. MIM powder metallurgy technology can be sintered to a dense, with good mechanical properties and surface quality of mechanical parts. At the same time, the plastic injection forming technology to large scale and high efficiency production with many complexity characteristics of parts: such as a variety of external grooving, external thread, the tapered outer surface, cross through holes, blind holes, concave part and the pin key, strengthen rib plate, surface knurling and so on, with to features of parts are unable to use conventional powder metallurgy method, precision casting process of.          

From the traditional powder metallurgy, metal injection molding industry in full swing in recent years, the domestic powder metallurgy industry seems to be growing. But horizontal comparison of the manufacturing process industry, powder metallurgy, metal injection molding in particular, the market is still just the tip of the iceberg. The number of products and the value of enterprise production, not to mention the "substantial".

The development of metal powder injection molding is influenced by several key factors.

a new type of forming technology, the development of metal powder injection molding is affected by several key factors. These factors determine the development prospects, development speed and development trend of the technology. These factors are well studied, can promote the further development of metal powder injection molding, and can not solve the problem of the development of the resistance.          

Metal injection molding technology of the material composition, including metal powder and binder two parts. Simply put, the powder metallurgy and metal binder in certain proportion, according to the provisions of feed mechanism and order in under the action of high temperature and shear stress were mixing and uniform structure of feeding and the granulator granulation. Due to the presence of binder, granulating material in the injection molding machine injection has good rheological property, can be filled completely to the cavity of the mold. After the forming, the body is obtained by taking off the organic component of the body and sintering the densification process, and the product can be obtained.          

From the seventies of the 20th century to the present only lasts for a few decades time, metal powder injection forming technology has made considerable development and progress, but from the development also exposed some of the shortcomings of current technical route and process route. These deficiencies in the objective to prevent the technology to a deeper level of development. So it is urgent to solve these problems.

The principle of powder metallurgy

Powder metallurgy is the preparation of metal powder or with a mixture of metal powder or metal powder and metal powder) as raw material, through forming and sintering, preparation of metal materials, composite materials and products of various types of industrial technology. With the popularity of powder metallurgy products in the market, the principle for the majority of users are more concerned about the technology of powder metallurgy. So ZCMIM today to explain: the principle of powder metallurgy, up to understand it:

1, the production of raw materials, we will according to the specific use of the product to determine the powder metallurgy processing of raw materials, there are many different types of metal powder and a variety of metal powder has different performance, processed products also has different performance, only to choose a good production of raw materials, to produce the most suitable products.

2, press forming and by selecting the raw materials to produce we can carry on production and processing, will be selected out of the metal powder by a professional mold for molding and forming method of the general with compression molding and compression molding.

3, after forming the needs of products after sintering process can make produced have better mechanical properties, more in line with the needs of the user. In general, we can use two methods of unit system sintering and multiple sintering to carry out the sintering process of powder metallurgy products.

4, sintering after treatment, due to various kinds of powder metallurgy products, so some need to carry out some of the sintering process, in order to meet the needs of users.

Powder metallurgy Damascus steel smelting products are very popular

Damascus tool steel is mainly used for cutting tools in various forms, from the shape of the limit. People use it as a hunting knife, used to peel, flesh, very easy to use; can also be made into a small knife, carry, had cut the rope, cardboard boxes and other things can use it easily calm. Although these things with common tools can be completed, but in Damascus, the feeling is not the same. And others use it to make traditional longswords, light steel will cost thousands of dollars and extravagance.

Now, made by powder metallurgy Damascus steel jewelry jewelry is very popular. From the style, the name "Damascus steel" shows a kind of martial spirit, and therefore more suitable for men to wear. If a man is always wearing the gold and silver, may let a person feel less masculine, and wear of the Damascus steel jewelry will not have this "side effects." From the raw material price, powder metallurgy jewelry of Damascus steel and silver prices of similar, but silver products, scrap collected can still use, and Damascus steel scrap completely into the scrap iron, so the product price is higher than that of silver.

Powder metallurgy jewelry of Damascus steel can also be used to make a variety of products, such as tableware, automobile, furniture accessories. It is said that the country has mobile phone producers in preparation for the development of the mobile phone shell of Damascus steel.

Traditional Damascus steel according to the genesis is divided into two kinds: the first is casting Damascus steel, also known as wootz steel, in ancient India, the lines are in the casting process of crystallization, and now have been lost; the second is forging modeling Damascus steel, welding lines of steel is also known, the lines by two or more than two kinds of folded steel forging play and.

This technology is widespread, various regions of the world are in use, but the style is different. But in modern times, the traditional Damascus steel in both performance and cost are not rivals of stainless steel products. However, in Damascus steel tends to decline when using the new technology of powder metallurgy in contemporary Damascus steel into sight, make people re application of this ancient steel saw hope......
