Powder Injection Molding is Sustainable

From point view of energy sustainability, general manufacturing process need a few traditional heating and re-heating process to forming. But when use atomized steel or iron powder, only  need melting scrap steel one time. All other hot working operations are carried out under the temperature below the melting point, which not only saving energy, and can be made into the final shape with required material performance and mechanical performance. By contrast of material utilization in powder injection molding process, found that the energy of manufacturing powder injection molding parts is 44% of required by forging, machining parts.

The MIM Process of Three Steps

MIM process(http://www.zcmim.com/helps/mimprocess.html) requires three steps:

(1) In condition of heating, pressure, injection the mixture of powdered metal and thermoplastics (or other binder) into mold cavity (similar to thermoplastic injection molding).

(2) Removing binder by heating or melting, only the metal powder left.

(3) Sintering the metal powder. Sintering temperature should be lower than the melting point of metal, but enough to make metal powder combined into solid metal (actual solid metal density is more than 96%).

Metal Injection Molding Process Applied in Sewing Machine Parts

Metal injection molding(http://www.zcmim.com/faq.shtml) technology was first introduced by national 863 plan, to produce high density, high precision, high strength, complicated 3D shape parts. It has the advantages of low cost, high efficiency, good consistency and good abrasion resistance, strong ability to resist high temperature, and easy to mass production. With the production of sewing machine industry as example, traditional production method is generally take cold extrusion process. Though its cost for blank is lower, it requires more than 200 times procedures, high artificial cost and low efficiency. Shuttle blank with metal injection only needs lathing once on each side, as much as 10 procedures can complete finish goods, saving more than 100 procedures than traditional process, greatly shorten the production cycle and save a large amount of labor.

application of powder injection molding technology drying machine

The application of powder injection molding technology is our immeasurable. Technology of powder metallurgy injection molding is also used in many places. The drying machine has a very significant effect on the application. Rotary metal powder dryer by rotary body, lifting plate, driving device, and the device made of a sealing ring, when the metal powder is transferred to the top, then enters the cylinder, can be copied to the rear plate rotation, in the dryer inclined, the metal powder by gravity and rotary force the role of slow down, on the other hand, has been repeatedly copying board toss, toss the metal powder after drying cylinder continuous uniform fall to form a uniform metal powder like a curtain flow. The drying of the metal powder is accomplished by the heat exchange with the strong hot air flow in the cylinder.

application of powder metallurgy oil bearing bearing

Powder metallurgy bearing is mainly used in general raw material powder by pressing, sintering, shaping, immersion process made. Now the machines are mostly relatively high degree of automation. Production is relatively large, most of the products can be formed at a time, so the larger the better production. And now with the mold less than a few words can do hundreds of thousands, more than one million words may do more than. But die cost is relatively high, so the lot of small words will not be done, and the time to replace the mold is long. Powder metallurgy oil bearing (oil bearing) is a kind of porous alloy product containing lubricating oil. When the shaft rotates, the friction between the shaft and the bearing of the increased oil bearing temperature and pump function.

Injection Molding Iron Based Gear Difficulty

Powder metallurgy request on mechanical properties is not high. But have high dimension accuracy requirement, the general density is 6.9 ~ 7.1, not high request on molding, but high requirement on sintering process. Adding Cu on sintering can prevent from deformation. With the development of technology, the demand for high performance powder metallurgy iron base part is higher and higher, the density of parts can reach 7.2 ~ 7.4. In order to further improve the mechanical performance of MIM parts(http://www.zcmim.com/), it is necessary to improve green part’s density, which must be from the powder preparation. Pulverizing powder and pretreatment technology is the key. Now use high quality water atomized iron powder, through plasticizing processing, compact density can reach above 7.9. This is the highest level for current powder metallurgy iron base parts, which would be unthinkable ten years ago.

Mobile Phone Processing Technology In 2017

Since the appearance of Xiaomi 5 ceramic glass shell in 2016, it brands new image of mobile phone. there is also news that iphone8 will use stainless steel and composite materials to explain a new generation of mobile phone shell. From process, the industry mostly used many milling to machine blank into shape, namely the so-called integrated molding technology. Through CNC, injection molding, polishing,grinding and anodic oxidation treatment can finish manufacture. In addition, stamping and die casting process are also used among them. Although metal injection molding (injection molding and metal injection molding) shorten production cycle, saving materials and reducing cost, but some bubbles happened in injection and uneven cooling question when melt combined with mould needs to be improved. Whether mobile phone processing technology stand out from the competitionin 2017, we look forward to it!
