Mold & die-set

01

Thermoforming mold

Multi-cavity forming tools cut to the thermoformer already on your floor.

02

Pressure forming mold

Where the part needs detail the vacuum alone will not pull.

03

Inline punch & die stamping mold

Three and four station machines, with the middle punch, trimming set and tray stacker matched to the trim.

04

Pressure box with cooling system

The half of the tool that decides how fast the part sets and releases.

05

Heavy gauge mold & cutting jig

Thicker sheet and larger parts. The tool stays flat and the jig puts the cut in the same place every time.

06

3D punch & die stamping mold

Where the trim line is not flat. Ground to the formed geometry so the cut edge stays clean across the field.

The cooling is drawn with the cavity, not after it.

Cycle time is decided long before the machine runs. Ports, manifold and circuit are laid out together with the cavity field so the part sets evenly and releases cleanly.

Mold and die-set work covers vacuum forming molds, three and four station thermoforming molds, middle punch, trimming sets and tray stackers.
