Mold transfer: moving an injection mold to a new factory

Moving a tool is routine work. What traps people is the order they do it in.

Filed under Molds and tooling

The short answer: a mold transfer takes five steps, in this order. Get the ownership paper signed, audit the tool where it sits, crate and ship it, check it fits the new press, then re-sample and match parts against the last good parts from the old factory. This is the work Jack does as part of injection mold making and tooling transfer. Who owns the steel is covered in the tooling custody note.

Before anyone mentions the move

Collect everything you can while the relationship is normal: maintenance condition, photographs, and the process setup the tool actually runs on, including machine size, cycle, temperatures and pressures. Keep retained good parts from the last lot.

Step one: ownership paper

Confirm in writing that you own the tool and that the current factory will release it. Settle any open invoices first, because an open balance is the most common reason a tool does not leave.

Step two: audit and crating

Inspect the tool where it sits: cavities, cores, slides, cooling lines, ejection, and wear. Photograph everything. Crate it with the inserts, spare parts and drawings, and record what is in the crate.

Step three: fit the new press

Check tonnage, platen size, tie-bar spacing, shot size and locating ring at the new partner factory before the tool arrives, not after.

Step four: re-sample and match

Run trials, measure against the drawing and against the retained good parts, and approve a first article before production restarts. Hold safety stock to cover the gap.
