LPMIM / METAL INJECTION MOULDING

Metal injection moulding From part design to production

Complex geometry. Considered material choices. A clear route to production.

We help engineering teams develop and manufacture complex metal components. LPMIM is the international brand of Lingpeng New Materials Limited, based in China.

What is metal injection moulding?

MIM shapes fine metal powder mixed with a binder, removes the binder and sinters the component.

It offers a manufacturing route for complex metal geometry when design, material and repeat demand justify tooling and qualification.

From fine powder to a dense metal component.

Powder and binder become MIM feedstock. Injection moulding creates a grey-black moulded part; debinding and sintering then remove the binder and densify the metal with controlled shrinkage.

  1. 01

    Metal powder

    Fine metal particles are the starting material.

  2. 02

    MIM feedstock

    Powder is mixed with binder and made into pellets.

  3. 03

    Injection moulding

    Heated feedstock is injected into the mould.

  4. 04

    Moulded part

    A grey-black, binder-containing “green part” is ejected.

  5. 05

    Debinding

    Binder is removed, leaving a fragile porous part.

  6. 06

    Sintering

    Controlled heating bonds the particles and densifies the part.

  7. 07

    Sintered MIM part

    The same geometry is smaller after controlled shrinkage.

PART SELECTION

Is your component a candidate?

Metal component examples with branching, threaded and flange features

Small components with multiple features, recurring machining operations or opportunities to combine parts are worth reviewing. Very low volumes, changing designs and large simple shapes can favour another route.

MATERIAL SELECTION

Function first.
Then the material.

Compare corrosion, strength, conductivity and processing requirements. Confirm the exact grade and manufacturing route for your project.

Material family illustrations. Availability and finished-part properties require project-specific confirmation.

ENGINEERING TO PRODUCTION

Define the project before committing to tooling.

Meet your engineering partner
  1. 01

    Requirements

    Share the application, material goals, critical features and anticipated demand. A discussion can start without a drawing.

  2. 02

    DFM and production route

    Review mouldability, sintering support, secondary operations and material selection.

  3. 03

    Tooling and samples

    Agree scope, responsibilities and a first-article inspection plan.

  4. 04

    Production readiness

    Confirm acceptance criteria, traceability, delivery requirements and change control.
