Five mold families, one tool room.

We specialise in designing and developing high-precision molds for complex, high-tech products and demanding production environments.

Mold & die-set

01

Thermoforming & pressure forming mold

Multi-cavity forming tools cut to the thermoformer already on your floor, with pressure forming where the part needs detail the vacuum alone will not pull.

02

Inline punch & die stamping mold

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

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

04

Heavy gauge mold & cutting jig

Heavy gauge tool with mechanical design. Thicker sheet, larger parts: the tool stays flat and the jig puts the cut in the same place every time.

05

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.

Forming, punching and stacking

On a multi-station line the pressure forming mold forms the parts, the punch and die cuts them from the sheet, and the stacker collects them.

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