The difference between metal powder injection molding and plastic injection molding

With the progress of the society, all kinds of new technology, new industry into the machinery manufacturing industry, constantly expanding the scope of the mechanical manufacturing industry, including metal powder injection molding are widely applied, metal powder injection molding is a kind of led out from the plastic injection molding industry to a new type of powder metallurgy near net shape technology, but some people will put mixed metal powder injection molding and plastic injection molding, actually they are not the same technology. In order to let you know more about the new material of dahong products, now xiaobian dahong new material to explain to you about the difference between metal powder injection molding and plastic injection molding knowledge.

Metal powder injection molding is a new type of powder metallurgy forming technology, high technical content, and plastic injection molding technical content is relatively low, the price is low, but the strength of plastic products is not high, have different processing process, vacuum sintering of metal powder injection molding need, and plastic injection molding, and also is there a difference in the injection process.

Plastic injection molding technology is similar to syringe used for injection, it is the use of screw (or plunger) thrust, plasticized good melting state (viscid flow) of plastic injection into the closed mold cavity, after curing and finalizing the product process.

Metal powder injection molding is the basic process steps of: first is selected to meet the requirements of the MIM metal powder and binder, and then use the appropriate method under a certain temperature to mix powder and binder into uniform feeding, after granulating in injection molding, molding billet after degreasing process for sintering densification into finished products.

Metal powder injection molding is actually an extension of plastic injection molding technology, in order to improve the flaws of plastic injection molding technology, can be added in the plastic metal or ceramic powder with high strength, good abrasion resistance products, increase the content of solid particles, and during the subsequent sintering completely remove adhesive and billet densification.

The above is by daihong new material xiaobian for you to introduce the difference between metal powder injection molding and plastic injection molding, whether there is a better distinction between the two characteristics?
