What we brought

  1. What we can do

    We design moulds that open cleanly

    Two parting lines release the runner, then the five dice. Guide pins align the plates; vents stop air traps.

  2. How we look after you

    You approve each round before we print

    Sea Almond approved the scope, the first design and the refined second design in our deck before fabrication.

  3. What you get

    Your team can run it themselves

    We filmed how to bolt the mould together and take it apart, and supplied the aluminium plate design to mill.

Production runs and finishing the moulded parts

At Additive Inn, our 3D printing studio in Singapore, we designed and 3D printed injection moulds for Sea Almond's hand press, one for a cup and one for dice. Sea Almond sent the real cup and dice, and needed moulds their own team could run.

Design & prototyping

Step 2 of 5

Each mould is a three-part stack: a cavity plate, a plate carrying the sprue and runners, and an aluminium plate on top that takes the nozzle's heat and force. The dice mould fills five dice per shot through a runner spider.

  2. First design · 11/07/2026

    Bolts replaced the clamps, and Sea Almond's idea of an aluminium plate was built into both moulds.

  3. Second design · 31/08/2026

    We split each mould into inserts and added guide pins, air vents and two parting lines so parts release cleanly.

Production

Step 3 of 5

We 3D printed the cup mould's plates in matte black, with the cavity and sprue as smooth resin inserts, so the parts are easier to make and assemble.

Build & assembly

Step 4 of 5

We bolted the cup mould together on its guide pins and filmed how to take it apart and close it again, so Sea Almond's team can do it themselves.

The final build

Step 5 of 5

Sea Almond has a cup mould that bolts together on guide pins and opens by hand, sized from their own cup. The aluminium plate is milled on their side to our design.
