Plastic parts from production

Want injection molding and production done affordably?

Our Injection Molding Package supports startups and mid-sized and large plastics businesses. We set up custom injection molds and mass production for any product or part.

  • Design to mass production

    We support you from product design to mass manufacturing, depending on your needs.

  • CAD files and samples

    We create or edit CAD files and make 3D printed samples before the mold is made.

  • Tolerances and shrinkage

    Molds need large upfront cost. We prepare each detail so the parts meet tolerance and shrinkage standards.

How you get your injection molding mold and more

Six steps from concept to production and QC.

Quality control of plastic housings
  1. 01

    Create a concept

    Without design files, we agree dimensions, shape and requirements with you, based on your sketch or reference. We then create a technical drawing.

  2. 02

    Optimize the parts

    Shapes must allow parts to fall out of the mold after injection. We check contact points, joints and other design aspects.

  3. 03

    Get a CAD/3D file

    The CAD file determines what your injection mold looks like. It specifies all dimensions. We create it only if you do not have one.

  4. 04

    Create a sample

    Before a steel or aluminum mold is made, a 3D print lets you check the shape. Tolerances and material differ from the final part. Final molds are not easily adjusted.

  5. 05

    Make injection molds

    We make the molds on CNC tooling, possibly from your approved CAD files. We make them only as complex as required.

  6. 06

    Arrange production and QC

    We run the injection molding and can package or assemble the product. Our own and partner factories have production lines next to the machines.

Why choose our injection molding package

The right injection molding company improves quality and lowers cost.

No expertise required

Send CAD files if you have them. We also help with every step and give feedback in any case.

Technical support

We help with material choice, mold type, assembly and shape optimization. We always provide samples first.

Mold options for your project

We weigh planned volume, cavities, product type and material, along with steel quality and precision.

Bundled projects, your molds

We bundle many projects in our own and partner factories for price and quality. The molds are your property and can be shipped anywhere.

Injection molding questions

What brands ask before they start.

What determines the total cost of an injection mold?

Four factors. Quantity: steel molds have no single minimum, as it depends on the product's sales price. Shape complexity: simpler molds suit simpler shapes. Size: large molds cost much more. Material: PP, PE and ABS allow simpler molds than PC or Nylon. We quote after reviewing your design files.

Why is it usually injection molding? What about other mold types?

Injection molding is the most common plastics process because it is versatile, fast and suited to volume. Bottles use blow molds. Long thin objects such as pipes use extrusion. Very large industrial objects can need rotational molding or thermoforming. We can help with those as well.

What are cheaper alternatives to steel injection molds made with CNC?

For prototypes and testing we use 3D printing or temporary aluminum molds before steel tooling. 3D printed parts cost several USD each, while molded parts cost a few cents. For most uses there is no real alternative to steel molds.

What about the IP of my designs and the ownership of the molds?

We always sign an NDA before you share your design. The IP of CAD and 3D designs we create or update is yours, even if you do not produce with us. Injection molds we make for you remain your property.

Where do your factories make injection molds and handle mass production?

At our own and partner factories in China and Vietnam. The plastics injection molding supply chain is well established and affordable there. In North America and Europe, even simple molds are costly.
