How it runs

From cross-section to pallet

  1. SM-01

    Draw and DFM

    Section review, wall thickness, shrink and drawability. Written feedback in three working days.

  2. SM-02

    Die and first sample

    Die cut on our own 5-axis CNC and EDM, then calibrated. 15–25 days to a first off-tool sample.

  3. SM-03

    Run and measure

    42 single and twin screw lines. Critical walls held to ±0.05 mm, colour matched to ΔE ≤ 1.5.

  4. SM-04

    Cut, punch and pack

    6 m lengths or cut to size. Foil lamination, printing, punching and welding run in line, not subcontracted.
