Injection-molded plastic gears

Custom
POM gears.

Low-friction gears for small motors and compact drives where noise matters. Molded to your drawing or sample. No drawing? We’ll design it with you.

01 / Process

From mold to motion.

A molded gear is only as accurate as its mold. We take on both, the mold and the molding, in one project.

Injection-molded plastic parts
Injection-molded plastic parts
  1. 01Design

    Tooth profile and fit checked for molding.

  2. 02Mold making

    The cavity is built to that design.

  3. 03Injection molding

    Trial samples first. Production once they’re approved.

  4. 04Inspection

    Checked against your drawing or sample.

02 / Gears

Gears we mold.

Spur, helical, worm, bevel, and compound. Hubs and stacked gears come out of the mold as one part. Resin, size, and tolerance are set for each project.

03 / Production

Operations.

  1. 01Injection molding

    Raw material is injected into a precision mold and comes out as the part.

  2. 02Chamfering

    The molded part is chamfered so sharp edges are removed.

  3. 03Quality inspection

    The finished part is inspected against the requirements before it is shipped.

04 / Material

Why plastic over metal.

Most of our gears are POM. When a gear needs a different resin, we mold that too.

  • QuietPlastic teeth mesh softly. No metal-on-metal whine.
  • Low frictionPOM can suit dry-running applications. Lubrication needs depend on load, speed, and the mating material.
  • Wear-resistantMaterial, tooth geometry, and operating conditions all matter. We review them for your application.
  • LightA fraction of the weight of steel, so less load on the motor.
  • Rust-freeNo plating, no coating. Fine in damp places.
  • Low cost at volumeOnce the mold is built, every gear comes out formed. No cutting per part.

For high torque or sustained heat, metal is still the right call. We’ll tell you if that’s your case.

05 / Applications

Where they run.

Anywhere a small motor drives a mechanism that has to stay quiet.

Parts from the project

Project / Motion products

POM gears for robotics, desks, and medical beds.

The need. Quiet gear mesh and stable tooth geometry in mechanisms operating near people.

Our work. POM material selection and injection molding to drawing, with a review of tooth profiles, assembly fit, and dimensional stability.

06 / FAQ

Before you ask.

What do you need to quote?

A drawing, CAD file, sample, or clear photos. No drawing? Tell us what the gear drives and where it fits, and we’ll design it with you.

Can you copy an existing gear?

Yes. Send the gear or clear photos of it, ideally with the part it meshes with. We work from that.

Who owns the mold?

The mold is part of the quote. Ownership, storage, and handover are agreed for each project before work starts.

What’s the minimum order?

It depends on the gear and the mold. We confirm it in your quote.

How long does it take?

Most of the time goes into the mold. You get a timeline with your quote.

07 / Quote

Let’s make it.

Send a drawing, CAD file, or photos of your sample. No drawing? Tell us what the gear has to do.

What happens next

  1. We review your drawing, sample, or application.
  2. We confirm the mold requirements, quantity, and critical dimensions with you.
  3. Once the requirements are clear, we reply by email with a quote and proposed timeline.
