Description
Technical field
The present invention relates in metal powder injection molding more particularly to a kind of feeding for metal powder injection molding
Preparation method.
Background technique
Metal powder injection molding (metal injection molding, abbreviation MIM) technology be a novel nearly end at
Type technology is the multidisciplinary phases such as collection injection molding technology, polymer chemistry, powder metallurgy technology and Metal Material Science
Mutually infiltration intersect product, using mold injection moldable blank by knot burn quickly be made high density, high-precision, high intensity,
The constitutional detail of three-dimensional complex shapes, the processes such as especially some complex-shaped utilization machinings can not process work and be difficult to
The small parts of processing.MIM technology can be completed freely, and have many advantages, such as that at low cost, high-efficient, consistency is good, easy shape
It produces in batch, is known as " components forming technique the most popular now ", therefore favored by insider.
MIM feeding is the core head section technique of metal injection molding product preparation, be by metal powder and forming agent according to
Certain proportion carries out the mixing of a period of time temperature in being kneaded granulation all-in-one machine under the conditions of certain temperature, then pelletizes, and is made
Feeding.
The preparation of MIM feeding has important influence to the density of metal powder injection molding product, therefore, how to provide
A kind of preparation method of MIM feeding, with improve the density of metal powder injection molding product be those skilled in the art institute urgently
The technical issues of solution.
Summary of the invention
In order to solve the problems in the prior art, the present invention provides a kind of feedings for metal powder injection molding
Preparation method, available highdensity metal powder injection molding product.
The present invention provides a kind of preparation methods of feeding for metal powder injection molding, by surfactant, gold
Belong to powder, organic binder melt blending processing formation mixture, mixture is kneaded using high shear mixer, directly
The feeding of metal powder injection molding is prepared.
As a further improvement of the present invention, the surfactant is stearic acid, oleic acid, zinc stearate mix.
As a further improvement of the present invention, the surfactant be stearic acid, oleic acid, zinc stearate, stearate,
Oleamide mixes.
As a further improvement of the present invention, the surfactant be stearic acid, oleic acid, zinc stearate, stearate,
Oleamide, polyethylene wax mix.
As a further improvement of the present invention, according to powder loading be 55-60% volume ratio, by metal powder with
Organic binder is uniformly mixed under conditions of temperature is 160~190 DEG C, forms mixture.
The beneficial effects of the present invention are: through the above scheme, the preparation process of feeding is optimized, it is available highdensity
Metal powder injection molding product.
Specific embodiment
The invention will be further described With reference to embodiment.
A kind of preparation method of the feeding for metal powder injection molding, using polymer blending modification technology, by table
Face activating agent, metal powder, organic binder melt blending processing form mixture, reach powder-modified purpose, are cut using height
It cuts mixer to be kneaded mixture, the feeding of metal powder injection molding is directly prepared.
Powder surface modifications, which refer to, is handled powder surface with physics, chemical method, purposive change powder table
The physicochemical properties in face, such as surface atom layer structure and functional group, surface hydrophobic, wetability and adhesion characteristics.For
For MIM injection moulding, high density, flawless metal parts in order to obtain, it is desirable that metal powder surface be easy to it is organic viscous
Agent mixing is tied, the injection feeding of high powder loading and low viscosity is obtained.Therefore, powder is modified, improves powder dispersion
Situation is very necessary, and the modified success or not in surface decides feeding dispersibility and uniformity, to the preparation of entire product play to
Close important role.
