metal injection molding degreasing equipment

Difficulties in metal injection molding:
(1) control the dimensional accuracy of parts
There is a certain gap between the precision of metal injection molding and that of traditional powder metallurgy. There is room for improvement in accuracy, mainly
It is controlled by fine process. Sometimes it adopts secondary processing, such as machining, heat treatment and polishing.
(2) reduce production cost
The cost can be saved by optimizing the production process, standardizing the operation and recycling the waste.

Future development direction of metal injection molding:
Although metal injection molding is attracting more and more attention, its scale is still weak compared with traditional processing technology, and it has great development potential.
The metal injection molding industry also needs us to take a series of efforts to develop and expand it, such as formulating industrial standards, accelerating industrialization, improving the quality of practitioners, developing equipment and striving for customers.
1) multi direction development of material system. Injection molding is an ideal near net forming technology, which can be economically formed and close to the final shape, and needs little or no follow-up processing after sintering. In the production of precision ceramics, it is mainly used in carbide, cermet, inorganic non-metallic ceramics, oxide ceramics, intermetallic compounds and so on.
2) diversified binders and multi-channel degreasing technology. Many binder systems based on cellulose acetate, polyethylene glycol, acrylic acid and agar have been further developed and applied. Computer-aided controlled thermal degreasing technology, solvent degreasing technology, catalytic degreasing technology, freeze-drying technology and microwave-assisted drying technology are all used in the research of adhesive degreasing.
3) more advanced and precise equipment. At present and in the future, the research on the precision control of the injection molding machine and the related on-line quality monitoring and control system and the development of the key equipment technology of the computer-aided degreasing are the focus of attention. Forming equipment, such as powder synchronous injection molding machine, uses double simple injection molding machine with coordinated control to produce composite parts.
4) in terms of industry, it is necessary to form a related industrial chain, with intensive cultivation. Only by thoroughly absorbing the technological and engineering capabilities, forming an ecological industrial chain and holding the industrial chain together, can we resist the risk and accelerate the development.

Metal injection molding performance and cost
Micro powder is used in metal injection molding, which can not only accelerate sintering shrinkage, but also improve mechanical properties, fatigue life, stress corrosion resistance and magnetic properties. Taking the processing of typewriter’s printing element guide rod as an example, it usually needs 14 processes to be able to go up and down, while using MIM process only needs 6 processes, which can save about half of the cost. When the ratio of material cost to manufacturing cost increases, the potential cost can be reduced more. Therefore, the smaller and more complex the parts are, the better the economic benefits will be. Through the above analysis, we can see that MIM molding has great potential.
