Still machining a part that could be made by metal injection molding?

Representative MIM gears, shafts and precision components on studio display

Many small metal parts are still produced through CNC machining, multiple secondary operations, or multi-piece assembly even when MIM may be a more efficient route.

If your part is small, complex, and intended for repeat production, MIM may help reduce unnecessary machining, combine multiple features into one part, and create a more scalable production path.

We review the drawing from our own press side and tell you if MIM is the right route before you commit.

What we do

We manufacture MIM parts for engineering teams that need a reliable production partner for small, complex metal components — drawing review, tooling, pressing, debinding, sintering, and secondary operations all run under one roof.

Metal Injection Molding Feasibility Review

Assess whether MIM suits your part based on geometry, expected volume, material direction, and tolerance requirements.

Drawing & DFM Review

Identify wall thickness concerns, undercuts, secondary machining needs, and features that affect production stability or cost.

Material Direction

Align the project around realistic material options such as stainless steels and other commonly used MIM alloys.

Prototype to Production

From first sample to scheduled volume — all run on our own presses and finishing line.

Is metal injection molding right for your part?

MIM is not the right answer for every metal part. It is most useful when the part is small, complex, and intended for repeated production.

When metal injection molding fits

  • Your part is small and geometrically complex
  • You are currently machining too many features
  • The part involves multiple pieces that may be combined
  • You expect repeat or ongoing production volume
  • You want a cleaner path toward repeatability

When metal injection molding is less suitable

  • The part is very large and simple
  • Production volume is extremely low
  • Nearly every dimension needs extreme precision machining
  • Another process already fits the part more naturally

If you are not sure, send the drawing. We will review it against our own pressing, debinding, and sintering limits and give a direct answer.

Why engineers switch parts to metal injection molding

Part Consolidation

Combine multiple features or components into a more integrated part design.

Less Secondary Processing

Reduce unnecessary machining, handling, and assembly steps where possible.

Fit for Repeat Production

A more repeatable manufacturing path for parts that need ongoing supply.

Complex Geometry Capability

Support shapes and features difficult to produce through conventional machining alone.

Materials and secondary processing

Each project is reviewed case by case. We match realistic material and finishing options against your drawing, performance needs, and production volume — all done in-house.

Typical projects may involve stainless steel, precipitation-hardening stainless steel, and other commonly used metal alloys depending on the application.

The goal is not to force every part into MIM. The goal is to identify the most workable route for your part.

How the process works

The earlier the drawing is reviewed, the easier it is to avoid the wrong process path.

1

Send your drawing

Upload your 2D drawing, 3D file, or basic project information.

2

Initial review

We review the part for MIM suitability, production logic, and major risk points.

3

Technical alignment

Clarify material direction, quantities, key dimensions, and any secondary process requirements.

4

Quote & timeline

If the project fits, we issue the quote directly, confirm tooling and production timing.

5

Prototype & production

We sample, validate, and scale to volume production on our own presses.

Why work with us

MIM projects often fail early for simple reasons: the wrong process was assumed, the drawing was not screened against real pressing limits, or changes got lost between engineering and the shop floor.

Because we run the presses ourselves, the drawing review and the production floor are the same team — fewer hand-offs, fewer surprises.

Fast initial review

Our engineers look at your drawing directly, not through a sales layer.

Production-first answers

Answers come from the press floor, grounded in what we actually run.

Drawing-first approach

We evaluate real parts against real tooling, not vague descriptions.

No middleman

Your drawing, the tooling, and the press that runs it all stay on the same desk.

Zetar Industry injection molding workshop, Shanghai

20 years in injection molding.
Now applied to metal.

Zetar Industry Co., Ltd. has been running injection molding programs out of Shanghai since 2005 — 45+ presses, ISO 9001 / 13485 / 14001 / 45001 quality systems, and 30+ English-speaking project managers delivering 100+ molds per month.

We now run MIM production on that same infrastructure — small, complex metal parts manufactured in-house under the same quality system.

Frequently asked questions

Can you help determine whether my part is suitable for metal injection molding (MIM)?

Yes. That is one of the main reasons engineers come to us. We review the drawing from our own press-side and judge whether MIM is the right route based on geometry, production logic, and project goals.

What files should I send?

A 2D drawing, 3D file, or both is best. If you do not have final files ready, you can still send basic specifications and part photos for an initial discussion.

Can metal injection molding replace currently machined parts?

Yes. Many inquiries start from parts that are currently machined or assembled through multiple operations. We can help review whether a shift toward MIM is worth evaluating.

Do you only support large-volume metal injection molding projects?

Project suitability depends on the part and the commercial context. Volume is important, but it is only one part of the decision.

Can you support prototypes before production?

Yes. If the project is suitable, prototype discussion can be part of the next-step planning.

Do you sign NDAs?

Yes. NDA discussion is available when needed.
