Tungsten alloy injection molding

Metal Injection Molding technology or MIM is a set of
plastic forming technology, polymer chemistry, powder
metallurgy technology and Metal material science and other
multi-disciplinary mutual penetration and cross product,
using the mold to the Injection forming and sintering ware
rapid manufacturing high density, high precision, the
structure of the 3D complex shape parts, can fast accurate
materialized the ideas of design for products with a
certain structure, function characteristics and can be mass
production directly from the parts, is a new technology of
manufacturing industry change.This technology not only has
less conventional powder metallurgy technology process, no
or less cutting, high economic benefit, but also overcomes
the traditional technology of powder metallurgy products,
low density, uneven material, low mechanical properties and
forming thin-walled, the shortcomings of complex structure,
especially suitable for mass production of small metal
parts, complex and has special requirements.
Tungsten alloy injection molding are widely applied, LED
lighting, quartz fuse, industrial furnace industry,
automobile industry, medical industry, the security field,
the oil industry, electronics industry, metallurgical
industry, nuclear power field.
High density tungsten alloy parts can only be produced by
powder metallurgy method.Due to its high strength,
hardness, extremely difficult machining after sintering.And
for the length to diameter larger products, suppress will
produce non-uniform density, lead to deformation after
sintering and dimensional deviation.Using metal injection
molding technology on the one hand, can be directly forming
a complex shape parts, on the other hand because it is
feeding uniform flow filling cavity, billet density uniform
throughout, eliminates the pressing process of an
inevitable phenomenon of density gradient.The MIM
technology since the emergence and development, preparation
has been used for many different kinds of high density
tungsten alloy parts.
