Hard Alloy Screw Barrel for Injection Molding Machine
Sintering
Parts:
There are similarities with the production
of ceramic powder sintering technology, are, therefore, a series of powder
metallurgy new technology can also be used in the preparation of ceramic
materials. Because of the advantages of powder metallurgical technology, it has
become the key problem to solve new materials, plays an important role in the
development of new materials in powder metallurgy products. Including milling
and milling which is mainly metallurgical process, and powder metallurgy
products and literal agreement. It is often far beyond the category of
materials and metallurgy, often across multiple studies (materials and
metallurgy, machinery and Mechanical) technology. Especially the modern
printing metal powder 3D, in Mechanical Engineering Cheng, CAD, reverse
engineering technology, layered manufacturing technology, numerical control
technology, materials science, laser technology, makes the product technology
of powder metallurgy technology has become a modern comprehensive more cross
discipline.
Based on different raw material,we can make
Carbon Steel Sintering and Stainless Steel Sintering parts.
Advantages:
Powder metallurgy has unique chemical
composition and mechanical, physical properties, and these properties can not
be obtained by traditional casting method. Be made directly using porous powder
metallurgy technology, semi dense or fully dense materials and products, such
as oil bearing, gear, cam, a guide rod, a cutter.
(1) The process of powder metallurgy
technology can minimize alloy composition segregation, eliminate thick, uneven
casting organization. In the preparation of high performance rare earth
permanent magnetic materials, rare earth hydrogen storage materials, rare earth
luminescent materials, rare earth catalyst, high temperature superconducting
materials, new metal materials (such as Al-Li alloy, heat-resistant al super
alloy, alloy powder, corrosion resistance of stainless steel, high-speed steel
powder, intermetallic compound high temperature structural materials) plays an
important role.
(2) It can be prepared by amorphous,
microcrystalline, quasicrystals, nanocrystalline and supersaturated solid
solution of a series of high performance etc. The balance of materials, these
materials have excellent electrical, magnetic, optical and mechanical
properties.
(3) It can be easily combined with various
types, give full play to the characteristics of each element of the respective
materials, is a kind of high performance metal based ceramic composite material
and low cost technology.
(4) It can make special structure and
properties of the production that ordinary smelting method can`t produce, such
as a new type of porous biomaterials, porous membrane material, structure and
function of high performance ceramic abrasive material.
(5) It can realize near net forming and
automatic batch production, which can effectively reduce the production of
resources and energy consumption
(6) It can make full use of ore tailings,
steelmaking sludge, mill scale, scrap metal recycling as raw materials, is a
kind of new technology can be effective and comprehensive utilization of
renewable materials.
Manufacturing
process:
(1) The production of powder. It includes
powder preparation, mixing and other steps. For powder molding and plasticity
improve powder usually add oil, rubber or paraffin as plasticizer.
(2) Pressing powder. Under the pressure of
15-600mpa, pressed into the desired shape;
(3) High temperature sintering furnace or
vacuum furnace. In a protective atmosphere in sintering. Unlike metal melting,
sintering at least one element is in solid state. The sintering process of
powder particles by diffusion, recrystallization, welding, chemical, physical
and chemical dissolution process of a series, as metallurgy products have a
certain porosity.
(4) Postprocessing. In general, good
Sintering Parts can be used directly. But for some high precision size
requirements and has high hardness and wear resistance of the parts but also
for sintering postprocessing. Postprocessing including precision pressing,
rolling, extrusion, quenching, quenching, oil, And infiltration, etc.
