Tooling and part continuity.

For parts that will be in production for years — components inside a device family, sealing parts on long-lived equipment, consumer parts on a rolling programme. The tool, the material spec, the drawing and the paperwork all held stable across every batch.

Why continuity matters

Because the third batch has to feel like the first.

Getting a part right on the first run is one problem. Getting the same part, from the same tool, in the same material, to the same feel and colour, three years later after a supplier has been through several material batches, several operators and probably a couple of process improvements — that's a different problem entirely.

We manage continuity through three linked disciplines: tool maintenance (the steel gets cleaned, inspected and, if needed, repaired between runs), material spec control (the grade, colour and cure system are fixed at first sign-off and don't drift), and drawing control (the drawing we mould to is the one you last signed off, not a marked-up copy in someone's inbox).

For every long-running programme, you have a named engineer who owns the tool and the paperwork. If the material supplier changes something upstream, you hear about it. If a batch drifts on colour or feel, you're told before it ships, not after you receive it.

For programmes that outlive the original design assumptions — a device selling well enough that the volume goes up — we can migrate the tool. Compression to LSR, single-cavity to multi-cavity, without redesigning the part from scratch. The migration is planned rather than emergency-triggered.

Drill down

2 ways we run tooling and part continuity.

Each variant has its own page with the specifics: where it fits, how we run it and what to send us.

Tool transfer

Your supplier has closed, moved, or stopped being reliable. You own the tools. We'll take them in, check them, and get parts running again.

Tool refurbishment

A well-looked-after tool keeps making good parts for years. Refurbishment catches wear before it becomes a quality problem.

How continuity is held

Three disciplines behind long-run supply.

Tool maintained between runs

The steel is cleaned, inspected and, where needed, polished or repaired between runs. Wear is tracked; if the tool needs a full refurb, you're told before it degrades the part.

Material spec locked

Grade, colour, cure system and supplier are fixed at first sign-off. Any change — even a supplier change forced upstream — is communicated before it hits your batch.

Drawing controlled

The drawing on our floor is the one you last signed off. Changes go through a revision process, not through email. Every batch references the drawing revision it was moulded to.

How a long-run programme runs

From first batch to fifth year.

First batch is signed off carefully because everything after it references it. The rest of the programme is disciplined repetition against that reference.

  1. Golden sample established

    First production batch produces the golden sample. Signed off by you against feel, colour, dimensions. That sample becomes the reference for every subsequent batch.

  2. Batch schedule agreed

    How often you want batches, how much notice you can give, whether we hold finished stock or make to order. That's built into the annual quote.

  3. Rolling batches against reference

    Each batch first-off checked against the golden sample. Material batch, tool ID and cycle count recorded. Any deviation reported before the batch ships.

  4. Tool servicing at defined intervals

    Between batches — or at defined cycle counts — the tool comes out for cleaning and inspection. Wear is measured; refurb is scheduled rather than surprise-triggered.

  5. Migration planned when volume shifts

    If demand outgrows the original tooling assumption, we plan the migration — usually compression to LSR — rather than being forced into an emergency retool.

To quote it

What a continuity programme needs upfront.

01

The expected life of the part

How long the parent product is expected to be in production. That drives tool steel choice and refurb intervals.

02

Volume rhythm

Constant year-round demand, seasonal, or ramping. Different schedules suit different tool designs and different cavity counts.

03

Change tolerance

Whether the part is likely to see revisions during its life. If yes, we design with revision in mind — modular tool inserts rather than a single monolithic cavity.

04

Documentation format

How your quality team wants batch records delivered. Easier to build the record correctly than to retrofit it two years in.
