Want to develop a plastics product but don't know where to start?

We offer plastic part manufacturing to companies of any size, from startups to large brands.

  • Accessible for everyone

    Custom molding for pure plastic parts or products combined with electronics and metals.

  • High quality molds

    Product design, mold planning and mold making, plus the related parts and assembly.

  • Cost and time savings

    Bundled mold orders cut development cost and speed up production.

Explore our plastics services: injection molding, 3D printing prototypes, plastic design and CAD, and blow molds.

How plastic part manufacturing works

Plastic part manufacturing in six steps, from a sketch to inspected production. You approve each one before the next starts.

Sketch of a computer mouse
  1. 01

    Develop a concept

    Send a sketch, a reference product or a digital image. We discuss the part and its use with you.

  2. 02

    Optimize the parts

    A list of every material and part, with hinges, joints and connections planned before tooling.

  3. 03

    Create the 3D and CAD drawing

    Every dimension of every part, so the molds can be planned and budgeted precisely.

  4. 04

    Get the prototype

    Professional 3D prints you can hold and test. We refine the design on your feedback.

  5. 05

    Make your molds

    Injection, blow or other molds once you approve the CAD and the prototype. The molds are yours.

  6. 06

    Arrange production with QC

    We set up the line and any assembly, then inspect each batch before it ships.

Why choose us for plastic part manufacturing

We handle plastic part manufacturing end to end, from CAD to molded parts, in our own and partner factories.

No expertise needed

Provide sketches, designs or a reference product and we handle the technical side.

Guided process

From 3D and CAD files to the right molding technique and plastic material.

Fast prototyping

Professional 3D prints first, refined in up to 5 revision rounds.

Your own molds

Once finalized, the molds are yours to use for future parts and projects.

Plastic part manufacturing questions

What brands ask about plastic part manufacturing before their first molded part.

What is the minimum quantity?

It depends on the part and the mold. Steel molds have no single minimum; they usually pay off from several hundred to a few thousand pieces in total. Blow molding of non-bottle parts starts at 10,000 pieces. Below that, we use 3D printing, vacuum casting or soft tooling. PET bottles are blow molded; see the blow mold page.

Can I just do 3D prints for a few items?

Yes. We 3D print any part without molds. For short runs, soft tooling or vacuum casting can be the better option. Send your CAD file and we will compare costs.

Where are your molds and production?

In China and Vietnam, where the plastics supply chain is mature and raw material is usually cheaper.

Do you work with biodegradable or recycled plastics?

Yes. We often use plant-based PLA and material made from recycled PET. We can outline the options for your part.

Are CAD files always needed?

Almost always. Only CAD files carry all three dimensions. The exception is a flat part with even thickness. We can make the CAD files for you.

Can I take my files and molds elsewhere?

Yes. Our files follow industry standards and the molds you pay for are yours. We can ship them to another molder if you ask.

How do you protect my design?

We always sign an NDA before you share your design. It is a standard step in our workflow.
