MIM Metal Powder Injection Molding

MIM is the abbreviation of metal powder injection molding, which is developed from plastic injection molding technology. Metal powder injection molding technology is a kind of near net shape technology manufacturing high quality precision parts. MIM make mass production easy, and get product quality stable and easy to control. Product’s structure is not restricted for MIM. Irregular surface can be realized by MIM technology too. Products with holes and grooves, concave and subsidence, thread, knurling, lettering, engraved trademark are all available for metal powder injection molding MIM too.

The processing for defect products of the stamping1

How to deal with the bad situation in the stamping process? Come with ZCMIM powder metallurgy process manufacturers to understand.

1 according to the material, product structure to determine the amount of deformation compensation;

2 according to the amount of compensation then design the model for stamping out the finished or semi-finished products;

3 processing semi-finished products to finished products;

The processing for defect products of the stamping 2

defect phenomena including crack, wrinkle, strain, uneven thickness, not forming etc.

(1) screw drill hole diameter and depth (bottom hole size according to the thread specification to determine the size); external threads to process to the thread size outside the circle (size is determined according to the specification of thread)

(2) Produce thread: internal thread use the corresponding grade; external thread by thread cutter or die threading.

(3) Defect phenomena including wire arbitrary deduction, not uniform size, thread gauge inspection unqualified materials etc. According to the requirements of the user to select copper, aluminum, low carbon steel etc which has lower deformation resistance, and good the plasticity good ductility of metal or non-metal.

For the inspection specification, according to the requirements to determine the inspection specification, like thread inspection has the GB thread gauge, hole inspection has the plug gauge or buy GB standard size gauge.

Powder Metallurgy Technology pplication

In defense industry, such as launch vehicles, missiles, aircraft engines, ships, nuclear industry, military electronics industrial heat and corrosion resistance refractory metals, ultra hard materials, those can only be produced by powder metallurgy technology. In modern science technology, nanotechnology is also a new field of powder metallurgy. Therefore, powder metallurgy technology always gain world attention as a new high technology in field of material science.

Powder Metallurgy Technology - Manufacturing of Mechanical Parts

Secondly, another major development direction of powder metallurgy technology is the manufacture of mechanical parts, including structural parts, oil bearing and sintered friction materials, etc.. Powder metallurgy parts started in 1916, used in copper based powder metallurgy oil bearing industry. With the development of automobile industry, powder metallurgy parts begin to be used in automobile manufacturing industry.

Metal Injection Molding—Sprue Gate Location

How to located sprue gate when design mould before metal injectionmolding process? There are some suggestions for your reference.

(1)   Choose nearest obstacle

(2)   Gate size and location should avoid  injection and peristalsis.

(3)   Gate should be located in the thickest part of injection part section

(4)    Gate location should make flow process shorter and less change of flow direction

(5)   Gate location should be  helpful for discharging inside cavity gas

(6)   Gate location should reduce or avoid weld mark so as to increase weld fastness.

(7)    Gate location should be selected to prevent material from extrusion deformation by cavity, core and insert

Powder Metallurgy Process—Pouring Gate Form

As explain in last article, pouring gate is also called  feeding throat or inner sprue.In  powdermetallurgy process projects, their pouring gates have so many forms. They can be generally concluded as follows:

Inside gate
Common side gate (edge gate)
Outer gate
Fan-shaped gate: used to  for  wide lamelliferous products

Flat seam type gate
Tab gate

Gap gate
Point gate
Subsurface gate
Disc ring gate
Spider gate

Claw gate
Circular gate
