Being refreshedWe’re updating our project images and write-ups over the coming weeks.

Render of the benchtop control unit: a cream enclosure on a navy base, with a screen and a control knob.

Injection Mould Tooling

Injection-moulded enclosure and tooling designs, including a control unit, clock face, chess set and two-part enclosure. Each design was checked with mould-fill analysis.

Benchtop control unit

  • Line render of the enclosure from its front corner.
  • Front view of the enclosure, with the screen opening and buttons.
  • Fill-time analysis of the enclosure shell.
  • Temperature analysis of the enclosure shell at the end of fill.

The enclosure is three parts, with 1° draft angles and a constant wall thickness, so each part fills evenly and releases cleanly from the tool.

Wall clock face

  • Exploded diagram of the clock face mould: plates, sprue, runner, ejector pins and cooling lines.
  • The clock face in CAD and as a rendered part, with its fill pressure plot.

The clock face has engraved numerals and two logo impressions. The mould must release these details cleanly, without drag marks or incomplete filling at the edge.

A centre sprue feeds a four-arm runner, with alignment pins across the parting line, and a stripper plate and knockout pins sit over the cooling lines for clean ejection. The fill study ran from 0.10 to 0.58 MPa across the face, confirming the numeral ring fills evenly.

Chess set

  • The six-cavity chess mould with a full set of pieces.
  • Fill analysis of the rook, with the crown filling last.

A full set means six turned profiles of very different volumes coming out of one tool. Each piece is split on its axis of revolution and sunk into matched plate halves, so pawn through king run in a single shot.

The rook is the hard case: a heavy base feeding a notched crown through a narrow neck. The crown fills last, at 0.63 s, with no air traps around the notches. Fill, pack and warp studies ran on every piece before committing the block.

Core and cavity

  • Tooling split of a vented enclosure into core, part and cavity.
  • Draft analysis of the enclosure at 3°, with every face resolved.

A vented enclosure with bosses and slots had to come out of a two-part tool with no side actions. A draft analysis at 3° confirmed every face resolves positive or negative.
