01 Mold Design

Mold Design

We design injection, blow and rubber molds. Every design is checked with mold flow analysis before any steel is cut.

Mold flow analysis, 4-cavity mold, Autodesk Moldflow.

Checked on every design

  • DFMDraft, wall thickness, undercuts, parting line
  • Mold flowFilling, pressure, weld lines, air traps
  • Gate locationEven filling, no marks on visible faces
  • Sink marksThick sections found and corrected
  • Air ventingNo burn marks or short shots
  • CoolingFlat parts, shorter cycle time

You receive the 3D mold assembly, 2D drawings and BOM, in native CAD and STEP. Mold design starts at $200.

02 Mold Manufacturing

Mold Manufacturing

Molds are made to the approved design and tested on our own injection molding machine before dispatch.

  1. 01

    Design approval

    You approve the mold design and the flow analysis.

  2. 02

    CNC and VMC machining

    Core, cavity and plates machined to the drawing.

  3. 03

    EDM and wire cut

    Fine details, sharp corners and deep ribs.

  4. 04

    Assembly and polishing

    Fitting, polishing, and checks on cooling and ejection.

  5. 05

    Trial

    First shots on our machine. Samples sent to you with photos and video.

  6. 06

    Dispatch

    Packed and shipped, or kept with us for production.

  • P20 steel for most molds. Harder steels for high volumes.
  • Machining with partner toolrooms, under our supervision.
  • The mold is yours after payment.

03 Production

Production

Plastic parts from our molds or from your existing molds.

From our mold

Production starts on the same mold once you approve the samples. Mold and parts are quoted together.

From your mold

Send us your mold. We check it, run trials, and start production after you approve the samples.

  • Sample approval
  • Quality checks
  • Export packing
  • Shipping documents

04 Part Design and 3D Printing

Part Design and 3D Printing

We also design plastic and mechanical parts, and 3D print samples to check fit before tooling.

  • Part design3D models and assemblies
  • Reverse engineeringFrom a sample or photos
  • Drawings2D drawings with tolerances
  • 3D printingFDM in-house, resin on request
